The ThrottleStop Guide (2020): How to Lower Temperatures, Increase Performance, and Boost Battery Life on Your Laptop

By Douglas Black , last updated on May 1, 2020

Background of this ThrottleStop Guide

I initially wrote the first edition of this ThrottleStop guide for UltrabookReview here as part of a short undervolting/tweaking guide several years ago. I published a more comprehensive guide for Notebookcheck back in 2017, but I felt it was time to update the guide for 2020. There have been quite a few bug fixes as well as a few new features added, but I also wanted to improve the readability and organization of the old guide. The current version of ThrottleStop at the time of writing is 8.70.6 (download link).

What is Throttlestop and how does it compare to Intel XTU?

ThrottleStop is an original program by Kevin Glynn, a.k.a. “UncleWebb”, which in simple terms is designed to counteract the three main types of CPU throttling (Thermal, Power Limit, and VRM) present in modern computers.

It started as a simple means to counteract some throttling mechanisms used in older laptops, check temperatures, and change CPU clock speeds. Initially much simpler and more limited than Intel’s Extreme Tuning Utility (XTU), ThrottleStop has grown in feature-set and stability over the years, and can be used for undervolting, “set-and-forget” temperature/clockspeed profiles, benchmarking, SST tweaking, and temperature monitoring.

In theory, XTU’s main advantage over TS was to be able to set PL limits and undervolt settings that would be kept applied automatically and would not require the program to keep running in the tray (as TS does). However, there have been quite a few bugs with XTU involving lost settings and frequent hard crashes upon resume from sleep, and for those reasons I have personally abandoned XTU in favor of TS. If you are reading this guide and plan to switch to TS from XTU, be sure you reset your XTU settings to default, uninstall it, and restart your PC before starting TS for the first time. Failure to do this can result in ThrottleStop reading your XTU-tweaked CPU register settings as the defaults (which they are not).

You might be thinking that these kind of programs are for the most advanced users or geeks who spend days trying to get their benchmarks a few points higher or temperatures 1-2C lower. While those stereotypes might be true for some TS users, the fact is that a few minutes of tweaking with the program will likely provide you with significant objectively measurable decreases in temperatures and increases in battery life and real-world performance.

A standard disclaimer when adjusting voltages and other settings on your CPU. There has never been a CPU damaged by this software to my knowledge.

Installation and first-time launch

Hopefully I’ve made my case for why you might want to install TS and give it a try. Luckily, there isn’t much to downloading and installing TS. You can always find the latest version of ThrottleStop in the first post of the ThrottleStop thread on NotebookReview’s forums.

After that, simply unzip the archive into a folder in a location of your choice (I like to keep a dedicated folder for tweaking utilities in my /Program files directory). I wouldn’t recommend installing it to the desktop if you have any intention of using the app, because later we will be automating the startup of the program using Task Scheduler, and if you move the TS director after doing so, you’ll need to do that all over again.

Once you’re ready to begin, double-click “Throttlestop.exe”. You will see a disclaimer regarding melting your computer; read it and then click “OK”. (I do not believe TS has ever melted anyone’s computer.)

After first opening ThrottleStop, you will be greeted by the main window of the program interface. It’s important to remember that all settings you see in ThrottleStop will be initially set to the default settings that your manufacturer has set for your CPU. If you ever want to revert back to your original settings for troubleshooting or benchmarking purposes, simply go to your ThrottleStop folder, locate the “ThrottleStop.ini” file and rename it or delete it, then shut down your computer cold before starting it (not restart). This will clear any settings or registers set by the program.

Note: If you get an error that TS could not be started because a file called “MFC120u.dll” could not be found, you will need to download and install both the 64 and 32-bit 2013 Visual C++ Redistributable Packages.

If you ever run into problems with your settings causing immediate crashes or all else fails, delete the ThrottleStop.ini file to reset all changes you’ve made.

The interface

We’re going to now go over the main features and terminology you will need to know to make your way around TS. If this is your first time tweaking your CPU registers, a lot of this terminology will be new to you. However, once you grasp the basic meaning and functions of each setting, tweaking will start to become second nature to you. As this is the latest (2019) edition of this guide, let’s start by introducing the newest features.

The main window of ThrottleStop 8.70.6. Also accessible from here are the options panel, TS bench utility, FIVR (voltage), and TPL (turbo limit) snap-ins.

New Features since 2017 (8.48)

Custom Logo – Starting with TS 8.70.5, it is now possible to customize the app with your own custom graphic. This can be done relatively easily by adding an image to the TS main directory called “logo.png”. The image can have a maximum size of 230×90 or less.

MHz/VID Min – You can quickly minimize the TS app by clicking on either the numbers next to the VID or by either of the MHz readings. Note that the app will minimize to either the tray or the taskbar depending on how the app is configured.

Clicking either the VID or MHz values will immediately minimize the app to your location of choice.

Main Window: Bottom

In the bottom bar of the main TS window you will see some buttons with basic functions: Save, Options, Turn Off(On), TS Bench, Batt, GPU, and a collapsing arrow to hide this bar.

Save – Saves the current settings to the ThrottleStop.ini file (found in your TS director).

Options – Goes to the options menu for ThrottleStop.

Clicking the “Options” button will open the options snap-in (right). Here, you can rename the 4 possible profiles, set tray icon settings, enable temperature alarms, battery profiles and monitoring, closing app behavior, and HotKeys. We will return here later when we setup profile alarms based on temperatures.

Turn On/Off – The developer has recently admitted that while this button used to do something years ago, it basically doesn’t do much anymore. Assume that TS will be governing your CPU as long as the program is running.

TS Bench – Opens a built-in benchmarking program. Though not strenuous, it is useful for detecting how recent tweaks you made will affect your CPU under load. In the top left area of the window, you will see four radio buttons. Each one has a customizable name (in the Options dialogue) and each refers to a separate settings profile for the program. A few settings are universal across all profiles, but most settings are profile-specific. We will discuss using more than one profile later.

TSBench is a handy tool to not only measure performance quantitatively with different loads, but also testing to see whether sustained performance is improved with your currently active settings/tweaks.

Main Window: Left

On the left half of the window you can find general settings that affect either CPU clocks or the way the program functions:

Outside of Undervolting, done in the “FIVR” snap-in, this section is where you will find most of the settings you will likely use to determine the behavior of your CPU.

Clock Modulation/Chipset Clock Modulation – These settings were designed to counter an older method of throttling which told the CPU or chipset to run at a percentage capacity. For most newer chips, this method is not used, and enabling the feature in ThrottleStop will have no effect.

Set Multiplier – This is another obsolete setting; on older CPUs, the clock speed is determined by multiplying the bus speed of the CPU by a multiplier. For example, an old Pentium III-M with a bus-speed of 133MHz set to a multiplier of 10 would be operating at its full speed of 1.33GHz. On modern CPUs, the multipliers are set differently. With a Core i CPU, simply increasing the default value by 1 will tell the CPU to run at full turbo clocks. Setting it higher will have no effect, and setting it lower will be the same as not setting it.

Speed ShiftEPP (Energy Performance Preference) – Starting with Intel’s Skylake, this became the new low-level (non-software) method for governing CPU behavior. It replaced the older “SpeedStep” technology, which required software-level governance. This means that EPP should be significantly more efficient and effective than SpeedStep was. If you have a Skylake CPU or later, this should be enabled. Note: On some Skylake machines (such as the DelL XPS 15 9560), this feature was never enabled via BIOS/firmware, despite that the chipset supported it. If your system has a Skylake or later CPU but it is not enabled by default in the BIOS, you can enable it by going to the “TPL” button and checking the “Speed Shift” option in that dialogue box.

Speed Shift – EPP operates with values between 0-255, where 0 means the CPU will prefer its maximum frequency (into the turbo range, assuming you have not checked “disable turbo”), and 255 means the system will prefer running the CPU at its lowest base clocks. I would recommend a setting between 0-32 in whatever profile you will use while plugged-in or want maximum performance on, and at least 128 for your unplugged/power-saving profile. You can play around with this setting yourself and watch how the clocks change while performing a strenuous task or running TSBench. This, along with “disable turbo” and the maximum turbo clocks under FIVR are the main variables you will likely want to adjust when creating different TS profiles.

Power Saver – Power Saver is a legacy feature that isn’t necessary on modern CPUs. Only available when turbo boost is disabled, Power Saver will tell your CPU to reduce its clocks to minimum when idle. This feature is redundant on anything newer than a Core 2 Duo, I believe.

Disable Turbo – This option will disable the turbo boost ability of your CPU when checked. For example, an i7-7700HQ has a base clock of 2.8GHz but can turbo up to 3.8GHz for a single-core workload. If you had tas this CPU and checked this box, the CPU will never attempt to boost above its base clock of 2.8GHz. This is useful when trying to limit spikes in power consumption (such as on VRM-throttling machines like the XPS 15 9550/9560/9570) or just in controlling temperatures when a dedicated GPU is in use as well.

BD PROCHOT – Short for Bi-directional Processor Hot. PROCHOT is an emergency throttling method triggered when a CPU hits its maximum temperature (100 or 105C). You will often see this triggered on MacBook Pros, for example. Bi-directional PROCHOT is a system some laptops use where the CPU will be throttled when another component, such as a GPU, reaches a set temperature even though the CPU has not his its maximum operating temperature. Disabling this box should disable this feature, meaning a hot GPU temperature trigger should not cause CPU throttling. Be aware that this may result in even higher chassis temperatures, and I would not recommend disabling it.

Task Bar – Ticking this check box will prevent ThrottleStop from minimizing to the tray and instead will keep it in the Taskbar. Set this to your preference. Note that this also determines where TS will minimize to by clicking on VID or MHz.

Log File – This will create a timestamped text log in your ThrottleStop folder. This is useful when you record your clocks and temperatures by the second during a benchmark. Keep it off when not needed.

Stop Monitoring – Clicking this will toggle the sensors and recording abilities of ThrottleStop.

Speed Step – On older CPUs (pre-Skylake), toggles the software-level governance of CPU clockspeeds.

C1E – This should be kept on anytime you are mobile or do not need the absolute minimum in system latency (DAW work, etc.). Turning off this option should prevent the turbo boost from shutting down cores automatically. When off, clocks should stay near maximum and the CPU will use more power.

On Top – This keeps the ThrottleStop window on top of any other windows.

More Data – Logs data at eight times per-second instead of once per-second.

Main Window: Right

The right side of the TS interface is more for monitoring purposes, though there are a few clickable elements.

The table will be headed with your CPU model, current voltage, and clock speed. In the table, each entry here represents one of your CPU’s threads. In the above screenshot, you can see that my CPU, a 6-core Intel Core i7-9750H, has 12 threads visible. If you were to turn off hyperthreading in BIOS, you would only see 6 in this window.

FID C0% Mod Temp Max
Frequency identifier/clock multiplier. This is usually equal to the current CPU frequency divided by the FSB clock. Percentage of time the CPU thread is in its highest-performance state (C0). This should be lower when idle and higher when under load. Refers back to the “Clock Modulation” options. Should read 100% on a modern CPU. Current temperature reading (C) of that CPU core/thread. The highest temperature reached by that core/thread. On a properly functioning thermal solution, the maximum temperatures of all cores and threads should be within a few degrees C of each other. This is useful for determining if you have a warped heatsink or poor thermal paste application. Can be cleared by clicking the “CLR” button below the readout.

Package Power – An estimate of how much power your CPU is drawing as a whole.

Temp – The current reading of the chip sensor (C). Note that this is often different than the individual core temperatures.

Limit Reasons – The two boxes here, one radio and one tick, serve to notify the user if any throttling has occurred. If TDP Throttle’s radio box is filled, then that means the CPU has throttled due to Thermal Design Power (TDP) restrictions. For example, if you have a laptop with a 135W AC adapter powering an i7-9750H and Nvidia GTX 1650, running an intensive game or benchmark may cause the combination of these components to exceed the total TDP allowed for the system, and thus it will throttle. If the PROCHOT [#]C box is ticked, then the CPU has at some point hit its OEM-designated max temperature. In the case of my ThinkPad X1E Gen 2, was set by Lenovo to 92C in a previous BIOS update.

FIVR, TPL, and C[#] are the more technical modules.

Below this chart lie 5 buttons: FIVR, TPL, BCLK, C#, DTS, and CLR. Only three of them do anything significant, however, and we will be mostly only be concerning ourselves with two of them: FIVR and TPL, though C[#%] is handy for ensuring your CPU is properly entering lower-power states.

CLR will reset throttling and temperature records.

Clicking DTS will simply change the temperature readings into degrees from the thermal limit rather than an absolute temperature (i.e. 25 DTS would mean 80C, 0 DTS would be 105C on many chips).

C#% will show the status of each of your CPUs threads in terms of its power state and utilization. This is useful when tracking down rogue programs and optimizing battery life.

BLCK sends a request to recalculate the bus and clock speeds of your CPU when pressed.

TPL is the Turbo Power Limit module, which is mostly useful for enabling Speed Shift on supported notebooks that don’t have it enabled in a BIOS update (i.e. the XPS 9550 and 9560). On some machines, some users have claimed to be able to set PL1 and PL2 limits through this module, though I personally have not been able to do so.

FIVR stands for Fully Integrated Voltage Regulator, and this is where we will soon go to undervolt our CPU soon. First, though, let’s take a trip back to the options to 


Use the Options dialogue to set up alarms and profiles for automatic functionality.

Before we go into undervolting, it’s important to set some options first. You may wish to give each profile a name or number so it’s easier to keep track of them. I recommend setting at least one profile to AC and one for battery, as well as “Start Minimized” and “Minimize on Close”, as I always run TS in the tray on all my computers. If your computer has a dedicated GPU, check the box corresponding to your card (Nvidia or AMD). Once you’ve chosen your GPU (if any), close and re-launch ThrottleStop for the settings to take. Now you should be able to see your GPU temperature displayed below your CPU temperature. It may be worth noting that if you don’t plan to use your GPU temperature to trigger any secondary profile, then you won’t need to check this box. It is possible that polling the GPU temperature may wake it up on occasion, but I doubt it will have any significant effect on battery life either way.


The first thing we’ll do is reduce temperatures and power consumption while increasing performance by undervolting. Undervolting slightly reduces the voltage supplied to the CPU. The first thing people ask is “why doesn’t Intel do this by default?”, and the answer to that is that every chip is different: some can undervolt to -160mv, others only to -60mv. Silicon manufacturers like to give a bit of headroom just in case, though some OEMs like Apple and Razer are now undervolting their notebooks’ CPUs out of the factory. You will still be able to undervolt a pre-undervolted chip, but don’t expect to see as much of an improvement as you would otherwise, of course.

There is no risk to undervolting (unlike overvolting), and the worst thing that can happen if you try to undervolt too much is that you will get freezes or BSODs (often under stress tests, but also at idle). To test an undervolt, run a benchmark. Sometimes it will crash immediately and you will know you have undervolted too much. Other times, an undervolt will work for benchmarks, but can lead to crashes on idle. In my own experiences, I find that undervolts are least stable on battery. If your undervolt is stable at idle and load while on battery, you can be sure it will happily run at those values when on AC power. If you do get a crash (often a BSOD, but sometimes a hard freeze), try reducing all your undervolts by 5mv at a time and see if the problem persists. Generally, too much of a CPU undervolt manifests itself in a freeze or BSOD, while too much of an Intel GPU undervolt will lead to a crash when running a graphics benchmark.

The FIVR module: Here is where the undervolting magic happens. We are mostly interested in undervolting “CPU Core” and “CPU Cache”.

Click the FIVR button to go to Turbo FIVR Control. You will see a lot options and sliders here, this process is actually very simple. Check to make sure you have the right profile selected (voltages can be profile-specific) then check the “Unlock Adjustable Voltage” box under “CPU Core Voltage”. There are 6 elements under “FIVR control”, but we only care about three: CPU Core, CPU Cache, and Intel GPU. In fact, CPU core and CPU cache should almost always be set to the same value.

Make sure the radio button for “Adaptive” is selected, as well as CPU core, and now we can select an undervolt for it. Only adjust the Offset Voltage. How much you should undervolt depends a fair amount on what chipset you have. In general, modern mobile CPUs undervolt very well (between -125-165mv) while older (3rd and 4th gen Core-series chips) may only be able to undervolt 40-50mv. For this guide, I suggest a conservative undervolt of -80mv for your CPU Core. Once that is done, click “CPU Cache” and perform the same steps. CPU Core and CPU Cache should generally have the same undervolt. It used to be suggested to run a modest -50mv undervolt on the iGPU, but there’s some consternation about this at the moment. Some have claimed this leads to stability issues waking from Standby and does little to reduce temperatures. If you are in doubt, just leave it at 0.

Once you have done Core, Cache, and iGPU, I recommend pressing “Apply”. If the voltages take and it doesn’t crash immediately, select “OK – Save voltages immediately”, as it is very annoying to re-enter all your voltages after a crash during testing. Before applying your undervolts to your other profiles, spend some time using your computer in various scenarios to confirm they’re stable.


Once your undervolts have been set, it’s a good idea to set up at least two profiles (if you have a laptop). The first profile should be set in Options to be your AC profile. Check the box for “Battery Profile”, and select another profile to use on battery (see above screenshot of the options for an illustration of this). This will cause ThrottleStop to automatically switch between the two profiles based on whether it is on battery.

Your AC profile should probably be the highest performance one, because there are no considerations needed for battery life. I recommend setting your Speed Shift value to 64 or lower for maximum performance on this profile.

Now click on the box in the main window for whichever profile you want to use while on battery. If battery life is a concern, I recommend checking the “disable turbo” box. Additionally, a more conservative Speed Shift value will help preserve battery life as well. Values from 128-256 are values that are biased towards battery life.

A third profile can be useful as a failsafe to cool off the laptop once a certain temperature has been hit. Go back to the “Options” dialogue box and you will see a section labeled “Alarm”. Rather than making a loud noise to wake you up, this feature will activate a profile of your choice while certain conditions are met. Remember that DTS refers to the number of degrees from max temperature, so a DTS of 1 means 100C on an i7-7700HQ. That is still quite hot, so I like to use a DTS of 20 (80C). Below that, you can enter which profile you want activated (select the number of your “failsafe” profile). Repeat the process for the GPU if you are monitoring it, noting that this box is measured in Celsius and not DTS. This method is quite useful for controlling throttling on machines that have been poorly configured to limit their TDPs, such as the XPS 15 7590 on launch

Click “OK” and navigate to your failsafe profile from the FIVR module. This third profile should be set to be triggered by one or both of your alarms (set in options). This profile should be designed to tame your CPU for various reasons, such as allowing your GPU more power and thermal headroom in a system with a shared heatsink. Once in FIVR, you probably want to lower the maximum turbo frequencies on the lower left. For example, if you set 32 as the maximum multiplier for all operations using 1-6 cores, then your CPU will never boost above 3.2 GHz on that profile. In the main window, you could also play with higher EPP values, such as 128-256. Alternatively, you could check “disable turbo” in the main window on this profile to limit the maximum frequency another way, but given the low 1.x GHz base frequencies of Intel’s chips nowadays, that might reduce performance a bit too much.

Now, when your CPU or GPU hit your desired temperature limit (set by the alarm setting in Options), ThrottleStop should automatically switch to the designated profile until the temperatures drop. Once they drop below the threshold, it will automatically return to your default AC profile.

This method of keeping temperatures in check is often preferable to letting the laptop manage its CPU and temperatures according to the manufacturer’s settings, as this allows you to effectively set your own customized temperature ceiling.

Automating TS to launch on startup

Once you have finished this guide and your computer is running more efficiently, let’s set ThrottleStop to launch on startup using Task Scheduler. There is step-by-step guide for this written by Kevin himself here once you’re ready.


This concludes your introductory guide to the wonderful, performant world of ThrottleStop! Due to the nature of modern CPUs and variants between systems, there is always a possibility that a feature that previously worked one way may behave slightly differently on newer machines and architectures. If you notice something isn’t quite working as described, try leaving a message here or making a post in the official thread at NotebookReview! Happy tweaking!

    Thx for the updated, detailed descriptions! I'm using ThrottleStop now on 3 laptops with great impact on improving performance on i5-8265U by 80%-90% and doubling the runtime on i5-4300U and i7-6700HQ laptops. The autorun doesn't work for me using launch command with profile switch (app shuts down after AC/battery switch), will probably post that and a related bug with my work-a-round here or on ThrottleStop page… anyway – great work!

      Have you checked the options to make sure "DC exit timer" isn't checked? That will cause TS to quit upon switching to battery :)

      • cosote

        October 8, 2019 at 8:02 am

        No, it's not checked. Also, this behavior happens only when TS is launch first time after boot as scheduled, manually starting TS again or even from schedule manually doesn't show it. My current work-a-round is to wrap TS inside a batch file infinite loop with start /wait – hehe…

    Hello, isn't power throttling also a way to avoid battery overheating ?

    • Douglas Black

      December 7, 2019 at 9:02 pm

      On battery, yes. The AC adapter should be more than sufficient wattage in most cases to avoid draining (only very poor examples like the Razer Blade stealth and Surface Book 2 drain while plugged-in).

    How to use factory defaults for sleep mode only?
    If undervolting is a problem in such case then a dedicated profile would be handy.

    • Douglas Black

      December 25, 2019 at 8:51 pm

      I know you can check the "default cache ratio" for sleep, and see if that helps, but I don't know of another way.

    I am experimenting with my brand new Thinkpad X1E2 (sounds like the same machine as yours).

    Should I expect to see a significant drop in average framerate in games when applying the undervolts? I get much better framerates without Throttlestop running than with it running, so I am not sure if I am missing something, or if I am not understanding the benefits of TS.

    My assumption is that I am not applying the performance tweaks correctly, but I am not sure. Is there a way to import someone else's settings?

    • Douglas Black

      December 27, 2019 at 9:51 pm

      Is the only thing that's changed the UV? Toggle that to see if that's causing the performance drop, or if is other settings

      • Jeff

        December 27, 2019 at 10:07 pm

        I played a bit more after making that post…

        I am running UV of -.125 for CPU core and cache and -.075 for iGPU for ALL profiles now (i had only applied it to the performance profile initially).

        I also turned off the ALARMS section to make sure it isn't dropping down to a lower profile during the benchmark (I am running a benchmark test from DiRT Rally on Steam). Finally, I changed the Speed Shift to 32 for performance mode (I tried a value of 1 here too). This actually did help – before any TS application I was getting 62 avg FPS, and with setting of 1 for Speed Shift, I get 95. With 32 Speed Shift, I get 94.

        I still see that the PROCHOT 97C tick comes in during the benchmark.

        • Douglas Black

          December 27, 2019 at 10:11 pm

          If you remove the UV ONLY does it fix the performance difference?

        • Jeff

          December 27, 2019 at 10:31 pm

          I'm not sure I understand that question. Are you asking what the FPS is if I leave the Speedshift settings and then remove the undervolts for the performance profile?

        • Douglas Black

          December 27, 2019 at 10:32 pm

          You hypothesized that the undervolt is causing a performance reduction. I am suggesting that you isolate all the different settings while TS is open to determine whether it is the UV or other settings as part of your profile. If the UV is indeed the issue, then simply disabling the voltage offset will fix the performance drop.

      I think you answered your own question. When you slow down your machine, framerates drop, as they're directly connected to your hardware's performance. The "benefit" is reduced heat and less wear on components. It's always a trade-off.

        December 30, 2019 at 8:41 am

        U may not have seen my other posts. I actually did see improvements when I turned off the alarm settings.

        I thought TS would effectively IMPROVE performance by eliminating or reducing the throttling that takes place due to thermals. (Hence the name Throttle-stop"). The hardware can spend more time in a faster un-throttled state so performance is increased.

        I need to run a few more tests where I change ONLY the under volt or the speed shift values to rule out the speed shift contributing to the improvement (about 62 FPS to 94 FPS).

  6. Jeff

    December 27, 2019 at 10:38 pm

    Ah – OK. My earlier reply actually corrected my assumption that the UV didn't appear to be the problem. I think it was either my ALARM configuration, or my Speedshift settings. My FPS improved nicely once I turned off the alarms and set the Speedshift to 32, even with UV active. I have now set the UV for -.140 without issue. Wondering how close I am to the limits now with my computer – might try going for -.150 next.

    • Jeff

      December 27, 2019 at 11:07 pm

      Well now I see I get a few errors using the TS bench test with both -.140 and -.150, so I have gone with -.130 for now as I get no errors under that setting.

    Hi, thanks for the guide; it's really informative and comprehensive. I have the same laptop as yours, the Thinkpad X1E2. I was previously using Intel XTU and only settings I had changed were cpu and cpu cache uv to -145, and I had huge performance gains. I scored about 2740 in cinebench r20, before the uv I had scored in the 2400's. However, my XTU settings were not sticking after reboot so I decided to try throttlestop. I reset my xtu settings to default and installed throttlestop and followed your guide. I undervolted to -145 on cpu and cpu cache, turned off C1E, turned off speedstep, set speed shift to 32, did not turn on alarm profile; and ran cinebench and am only scoring in the 2300s. I've tried playing with multiple settings, changing speedshift from values 0-64, turning on C1E, etc. Seems like it's throttling a lot more with throttlestop settings than it was with xtu. Not sure what settings are causing problems for me. Would you be able to share your settings?

      Did you have increased TDP in XTU ? That might be the thing. I'm not sure if TS can increase TPD as well.

    Thanks for the effort, this might be the most detailed guide on the internet I have ever seen!

    I have a question for you that I couldn't find an answer for in this guide nor in the others.
    I have an i3 6006u CPU and when I have CPU Core -115 mv and Core Cache -75 mv it works just fine but when I make both of them -115 it crashes immediately.

    You said they usually should be on same value. Can this cause any problem and should I leave it like this or adjust both of them a value which CPU Core and Cache will be same (in this case -75) ?

    Thank you for your answers in advance :)

    • Douglas Black

      January 6, 2020 at 6:17 pm

      As far as I know, the cache is the actual value that will be applied if it's different between the two. So actually with your settings you will only be getting -75mv with -75 on the cache, and that's why changing to -a higher UV on cache causes the crash.

      • HK

        January 10, 2020 at 3:13 pm

        Thank you for your fast answer, I wasn't waiting that ahhhahah.
        Actually interestingly after following your guide I always got BSOD, then I cleared the settings and readjusted the voltages at the same voltages, now it is working. I guess there was a problem on AC, Battery choice on options. I may understood it wrong or maybe you can add more detail about them on your guide. Thanks for your reply and answer again.

    My laptop get so hot when I'm gaming but I don't always play games. Sometimes i went a week or two without playing. I want to know if i can choose to use throttlestop only when I'm gaming. Or do i still to keep it open regardless. If i choose to open it only when I'm playing games, will it affect/damage my cpu later? Thank you.

    • Douglas Black

      January 8, 2020 at 6:11 pm

      There is no downside to running it all the time, and no possible risk of damaging your hardware with it though undercoating.

    January 17, 2020 at 4:46 pm

    Hello and thanks for this guide!


    You said "There are 6 elements under “FIVR control”, but we only care about three: CPU Core, CPU Cache, and Intel GPU."


    "It used to be suggested to run a modest -50mv undervolt on the iGPU, but there’s some consternation about this at the moment."

    So I didn't understand if I should only change iGPU and don't change Intel GPU at all, or change both Intel GPU and iGPU to the same value.

    • Noah Lauziere

      April 28, 2020 at 10:56 pm

      You can see in the FIVR picture they undervolted the iGPU Unslice so that's my guess. Hope that helps!

    • Andrei Girbea

      February 26, 2020 at 12:57 pm

      I'd start with a slight -50 mV undervolt, run CInebench for a few loops, then try -60 if stable and so on until it crashes. COre Us normally undervolt within -60 to -100, based on silicon lottery.

    March 29, 2020 at 11:11 am

    Hello, thanks for the guide!
    Still, there's a thing I can't get. I change options in FIVR menu, I set my Offset Voltage. But I see no changes in the window placed in top right corner, it's still "Default" and +0.0000 value.
    There's a screenshot:
    Does it mean that the program really doesn't change the voltage or it doesn't show the changes?

    • Douglas Black

      March 29, 2020 at 11:17 am

      That indeed suggests the voltages are not being changed for some reason…

      • John

        March 31, 2020 at 3:58 pm

        So what could be done here?

        BTW, Intel's XTU application doesn't allow me to change Offset Voltage, only Turbo Boost can be set. Does it mean that my CPU is somehow preventer from undervolting?

        • Douglas Black

          March 31, 2020 at 4:49 pm

          It's more likely that it's your BIOS that is not letting you UV. Unless you have a 1/2nd gen CPU.

        • John

          March 31, 2020 at 5:20 pm

          No, it's i5-9300H. So only BIOS undervolting could be a solution?

        • Douglas Black

          March 31, 2020 at 5:27 pm

          What I mean is that I'm not sure why you can't undervolt with that CPU. The only reason I could think of is that your manufacturer disabled undervolting in the BIOS. The only manufacturer I've seen do that before is Apple. What laptop do you have?

        • John

          July 8, 2020 at 9:48 am

          Intel has disabled undervolting on a lot of laptops due to Plundervolt. There might be a setting in the BIOS to allow undervolting again or you could try to downgrade to an earlier BIOS without this 'fix'.

  15. John

    April 3, 2020 at 5:58 am

    Sorry, Douglas, it took a while to come back to our conversation.
    "What laptop do you have?"
    Dell G3 3590

    • Douglas Black

      April 3, 2020 at 6:13 am

      No worries. I think it's very strange you can't undervolt with TS or XTU on that. Are you on the latest BIOS? You have successfully undervolted using TS on other laptops, right?

      • John

        April 4, 2020 at 6:06 pm

        Well, my laptop is quite new and with latest updates installed, but I'll check it again, thank you.

        Actually, no, I haven't done it before, but after reading a couple of manuals I think I could handle it haha.

        • John

          April 4, 2020 at 6:19 pm

          Also, my XTU screenshot. Everything's simply blocked.

          I've got an Inspiron 7590 and Dell disabled undervolting on latest Bios, had to rollback to be a able to.

    • Tony

      April 17, 2020 at 5:23 am

      John, on the G3 3590 you'll need to downgrade your BIOS to 1.8.0, then go into the BIOS and reset it to the system defaults. I just got one of these laptops myself and was able to get to -155mV with some apparent stability. (I'll see what happens after letting Prime95 run overnight.)

      Intel's released a microcode update blocking undervolting to stop a security vulnerability.

      You can read more details at the following link:

      • Jeff

        April 17, 2020 at 6:06 pm

        So is it fair to say that if the values show up in the FIVR table on the upper right, undervolting is still working?

        I just got a BIOS update on my Thinkpad X1E2 (which is CRITICAL to me since it is supposed to have fixed a very common issue with missing keystrokes), and I checked throttlestop and it still appears to show the offset voltages in that chart.

  16. Jeff

    April 14, 2020 at 11:02 pm

    I just had a random blue screen on my computer (Thinkpad X1E2), with a message something like "DRIVER_POWER_STATE_FAIL" (or something similar). Could this have been a throttlestop issue?

    I wasn't doing anything with it at the time – it was just running next to me while I was using a different computer. I am running Folding @ Home on it.

    • Douglas Black

      April 14, 2020 at 11:36 pm

      Possible. Reduce UV by 5mv and see if it occurs again.

    • Tony

      April 17, 2020 at 8:41 pm

      Yeah, that's fair to say. Seems to have been borne out in my testing so far.

      I really need to do a repaste on the G3. Even with the aggressive undervolt, it still hits max temp. But my Fire Strike scores are improved.

  17. Muhamad Rafdan Maulana

    April 15, 2020 at 3:11 am

    I have an Asus A412FL. Tried undervolt it to -80 mV for CPU, and -50mV for iGPU but there were no difference. In fact, it was worse. Right after I undervolted it, I launched Watch_Dogs, CPU temp went wild at avg 77-80C (90C peak). Is there anything wrong with what I do?

    • Douglas Black

      April 15, 2020 at 3:15 am

      I can't imagine that it would make it worse. Undo the undervolt and check temps again.

      FYI, I should warn that Dell is disabling undervolting on their PCs. My XPS 15 7590 is the latest victim.

          You'll need to install the x86 as well as x64 library

          As for what are the best settings… Epp of 0 and set up a profile to cut back the CPU when the temps get too high like I've shown in the guide will help for gaming

    Odd question – when using TS, does the windows power management feature do anything? (I mean the slider that appears when you click the battery icon in the system tray that reads "Best Battery Life <-> Best Performance".

    • Douglas Black

      April 19, 2020 at 1:22 am

      That's a good question actually, because windows power management, traditionally (for sure until Windows 7) did interfere/interact with TS settings. For this reason, its programmer (Kevin) has always suggested to put it on max performance when plugged in (as my TS settings are for max performance too on AC). When I am unplugged, I put it on power saving mode in Windows because my TS profile for being unplugged also biased towards saving energy at the cost of performance.

      • Jeff

        April 19, 2020 at 1:56 am

        So do the windows setting change anything in TS? Or vice versa?

        What does windows power settings do normally? Obviously it isn't undervolting, but is it limiting something with regard to CPU frequency?

        • Douglas Black

          April 19, 2020 at 2:05 am

          I think we could generalize and say that the Windows power settings may change or somehow influence the boundaries one sets in TS.

          As for what windows power settings do themselves… that's harder to say now than ever, with Microsoft walling-off more and more of the technical control of the system from users. They change the EPP levels now, mostly. Between 0 and 192 I think.

      Turn On/Off – The developer has recently admitted that while this button used to do something years ago, it basically doesn’t do much anymore. Assume that TS will be governing your CPU as long as the program is running.

      So, doesnt matter on or off. its always on. I tried it as well.

    April 30, 2020 at 2:58 am

    Hi! great guide, thanks!!!

    I have a question… you say "This means that EPP should be significantly more efficient and effective than SpeedStep was. If you have a Skylake CPU or later, this should be enabled". I have a Core i7-6700HQ but when I first opened TS that option was not enabled, SpeedStep was. Does it mean I should activate Speed Shift AND deactivate SpeedStep? Thanks!

    • Douglas Black

      April 30, 2020 at 3:11 am

      That "speedstep" check doesn't really control the actual legacy speedstep function of chips, I believe. Leave both of those checked for the proper speedshift functionality.

    I use programs like Prime95 or AIDA64 to test the undervolt stability.
    Do you have any advice on some specific program to use (other than the ones mentioned) and on how long the stress test should take?

    • Douglas Black

      May 2, 2020 at 6:01 pm

      Outside of those programs, I would unplug the laptop and use it however you most frequently use it. Let it idle, as well — sometimes machines are less stable when idling than when under load for undervolt. If you don't get any crashes after a day or so, you are pretty golden.

    Please help….

    • Douglas Black

      May 7, 2020 at 7:59 pm

    Thank you for such a great guide. However, I have a question regarding the TS Bench tool. What does the Size mean (64M, 256M and 1024M) and which of the numbers should be used in different situations (or which gives the most reliable results in terms of stability)?


    May 24, 2020 at 2:27 am

    I´ve been able to undervolt my I7 9750h up to -140mv. I could do more than that when my CPU is under load, but I get some crazy BSOD when my CPU is idle.

    Can I have a stronger undervolt under heavy load and softer under light load?

    • Douglas Black

      May 24, 2020 at 3:24 am

      That's sort of possible, but I don't know how reliable it will be. You could set an alarm for a relatively low temp like 70 to switch to a higher undervolt, and switch back to a higher UV for lower temps. Just needs 2 profiles

  31. Stan Wang

    May 25, 2020 at 2:46 am

    Hi, thanks for the guide. When i click on the battery icon on the taskbar, there is a slide for energy profiles. How does this and throtlestop interact with one another? After havingconfigured throttlestop, will the windows energy profiles still have effect and if so, is there a recommended sor it?

    • Douglas Black

      May 25, 2020 at 3:13 am

      Those slider profiles just affect EPP, AFIK. They will occasionally override each other (I think TS tends to override windows though), so I would use the profile/TS setting that harmonize (e.g. zero for highest performance)

      June 6, 2020 at 12:04 am

      You're welcome! Those numbers are the size of the file (I believe) being benchmarked with. 64m is the shortest benchmark, 1024 is the longest. For stability, I would test with prime95, because none of those benchmarks run long enough – – they are for comparing between machines.

I have a MSI GL62 7QF with gforce 960m, and using it's dedicated dragon boost to gain "max" performance. Playing newer games casues overheating issues and low fps on some games (for ex cod warzone). Stupid question, but just to confirm, is this TS something that could help me more than a cooling pad?

    Doug i need help, i did undervolting using throttle stop and followed your guide and i got pleasant temperatures, and i did it all the way to -110mv, then i decided to go all the way to -140mv so i can get my cpu range to around 70-80C but as soon i put the new change in i applied and saved it instantly , and then my laptop crashed , and it did so bad i had to factory reset it, and before at idle my laptop was around 39 to 45C CPU temp, but now it shoots crazy from 45 to 60 or even 78C and my laptop doesnt do anything! how can i undo , or fix this problem? because there is no way i can play games with that much temp, I have A MSI GS75 Stealth with RTX 2070 Max-q and i7 processer. i really need help on this.

    • Douglas Black

      June 13, 2020 at 5:12 am

      Those temp changes can't be caused by TS, I think. It's more likely to be CPU usage. If you accidentally set and saved your undervolt too low and TS is set to open in startup, go to the TS directory and delete the throttlestop.ini file

      • Michael Reyes

        June 13, 2020 at 7:20 am

        thanks for the reply, my laptop CPU never shot around this crazy before though, it happend after i used TS and it cause me to have many crashes then i had to factory restore my laptop, if i use TS using stable settings from now on , would i have to use it forever?, and i noticed my CPU actually overclocks by it self on idle, when my CPU temp shoots around from 40 to 65C.

    Thank you for the tutorial.
    Unfortunately on my new Dell Precision 5550 (The XPS 15 9500 business twin) with i7-10875h applying the CPU core and cache voltages does nothing. :(
    Offset remains unchanged after.

    Reading the previous posts I also checked the XTU software and the voltage offsets are also greyed out.
    Does this mean that Dell has blocked undervolting on their latest laptops by default in the BIOS?

    What can I do?

    • Douglas Black

      June 14, 2020 at 7:23 pm

      Yes, they have blocked undervolting. You can return the laptop to them and let them know it's because they disabled undervolting.

    Thank you so much for this guide and it's previous versions.

    I have updated my settings a bit mostly replacing 'disable turbo' with a scaled down turbo (30-26).

    However despite my UI looking like yours, I see no way to actually set the Speed Shift – EPP, just 128 when the box is checked and the green SST.

    I have ticked 'enable SS when starts' in TDP, but the 'Speed Shift' boxes is greyed out as ticked.

    I'm running a i5-6300HQ in a HP-Pavilion laptop.

    Any idea why I don't seem to have any way to change EPP?
    As I can't see any boxes or sliders in your screen shots.

      Speedshift may need to be activated in the TLP dialogue box, as you have an older cpu

      OK, I'm an idiot.
      I've been using this around 4-5 years and I never realised that you could type in an EPP value.

      I always assumed it was just displaying 128, even double clicking on it, it just highlighted the flush text.

      Ah well, mystery solved.

    Hey, I'm on Alienware 15 R2, recently my system has been lagging while doing normal things let alone gaming, my PCH thermal temps are really high.

    What should I do to improve my gaming experience. Any help would be appreciated

    Great guide. Unfortunately, I don't have the FIVR button since I am trying to undervolt a 7 year old Alienware with a 3rd gen CPU that was sitting in a closet fEor my nephew. The laptop is in great condition and running fine but on some games, it runs very hot (up to 100°C) and repasting didn't help much.

    Any way I can still undervolt using ThrottleStop without using the FIVR option?

    Hi, I'm suffering from the Power Limit Throttling with Dell XPS 15 9550 (i5-6300HQ, GTX960m). The manufacturer set it so that when the machine reaches 45W TDP, the laptop will throttle. This causes massive lag and stuttering when gaming.

    I have already set it to be -0.145V in ThrottleStop. Should I increase the TDP to 56W in TPL section? Also there is a "Clamp" button in the TPL, could you explain what does it do? Are there any other methods to lower power consumption so that the laptop TDP doesn't reach the 45W threshold?

    Well, i do undervolting and gained performance on a i5-8265u it can stay at 3.9ghz for a while but when reach 70º it downs its frequency but prochot is to 95º, why this happens?

      Sounds like your manufacturer set a temperature trigger at 70C

    Hey thanks for the great gruide. I'm using the HP Omen 15 2019 model
    processor- i7 9750h
    gpu- rtx 2060

    should i reduce the turbo boost short power max from 90 to a lower value?

      Reviews say that laptop runs very hot, so it wouldn't be a bad idea to do so.

    Quick question. i noticed while adjust the offset to .-125mv it would not change on the table on the top right corner. its shows everything as +0.00. even with my adjustments haven't noticed any difference on my laptop when trying the benchmark

    Laptop is a MSI GL65 -10sfk
    i7 10th gen 27070 rtx

      That indicates that undervolting is disabled on your system. Since MSI is an enthusiast OEM there might be a UEFI setting you can toggle to re-enable it.

    What is the meaning of a green "T" icon appearing on my Throttlestop?

    I updated my surface book 2 (i78650u,16gb ram,gtx1060) to windows 2004 and I noticed a sudden drop in fps(from around 100 to 20 or sometimes <10) while gaming. When I opened the task manager, I saw that the cpu's performance went down at the same time.This kept repeating.This didn't go away even after reinstalling drivers(up to date) and windows itself.
    Thinking that it's a throttling issue,I used your guide to setup throttlestop to reduce temperature and power usage. It successfully did so with a significant change but then the throttling still existed.The games still went through low frame rates like I mentioned above.

    I am not sure if I did something wrong,so can you please help me out here? I can't play my games properly and throttlestop seems like my only hope now.

    I've uploaded screenshots of my settings and the performance stats at the time of the drop with throttlestop on and off for comparison.Please go through this and let me where I went wrong.The same game with the same settings was played.

    Also can you please tell how to interpret the ts benchmark? I don't know what the numbers mean.And the limits too please.

      I forgot to ask one more thing.

      If I turn off BD PROCHOT if the temperatures are well maintained(like in the screenshots in the link) will it be an issue? I read somewhere that this is the setting that protects the cpu from getting fried but the temperatures won't go that high if I use throttle stop right?

    Thanks for sharing, throttlestop really helped making my laptop less loud, though i should probably just have gone with a less powerful one haha

    -160 ON CPU voltage and cache with the recommended settings as you stated. Runs stable except I still hit 97C while stress testing or gaming but only 2 of the cores (9750H) get this hot and throttle me still. So I'm thinking either a crap CPU and/or need to redo the thermal paste. The RTX 20170 Max-Q runs all games at Ultra and never hits 90C. Haven't OC'd the GPU since frame rates are fine with the 144Hz panel. Skyrim SE heavily modded with 2/4K textures and ENB will drop the RTX pretty good down to 35'ish fps. Thanks for the guide
