How to upgrade the memory on the Asus Vivobook and the Transformer Book Flip series

The Vivobooks and the Transformer Book Flips are two series of mid-priced Asus ultrabooks, spanning over a bunch of different models.

You’ll find Vivobooks with screen-sizes between 11.6 and 15.6 inch, while the Book Flips are available as 13.3, 14 and 15.6 inch variants. In fact, I’ve tested a few of these over the last months, including the Vivobook V551LB / S551LB, the Vivobook S301/Q301, the Transformer Book Flip TP300 and the larger TP500 model.

All these devices leave room for user upgrades, as they offer a spare memory DIMM (alongside the 4 GB of memory soldered on the motherboard) and use standard sized 2.5″ 7 mm storage drives. And while the storage is easy to replace, the memory might pose difficulties, mainly because the slot is hard to find unless you know where to look at.

I’ve added a few pictures below with the internals of all these laptops and all of them have one thing in common: a silver rectangular cover placed near the processor. Well, there’s where the RAM slot is, behind that cover. So in order to add more memory on these Asus laptops, you’re going to have to first remove this shield.

BTW, if you’re asking what the purpose of this cover, I cannot offer you a clear answer. It’s probably some sort of electro-magnetic barrier, but I cannot confirm this. One thing I can confirm is that Asus only uses this kind shield on their more affordable ultrabooks, while on the Zenbooks (UX301LA, UX303LN or the NX500JK) the memory slot is unshielded and easier accessible.

Anyway, thanks to our reader David Tapp who sent us the pictures below, I could put up together this quick guide that will take you through the steps of upgrading the RAM on the Vivobooks and the Transformer Book Flips. So here we go:

  1. Buy a compatible memory stick. From what I can tell right now, both the Vivobooks and the Transformer Book Flips can only take an up-to 4GB module in the spare slot, for a total of up-to 8 GB of memory;

Recent update: One of our commenters, Andrew M, confirms that 8 GB modules do work on the Asus V551 and probably the others, however you need to get low-voltage DIMMs: “Hi Guys, I just purchased an 8Gb SODIMM and installed it under the silver cover.I can confirm that the 8Gb module I used works fine and Windows 8 reports my machine as having 12gb of RAM. You have to get low voltage ram – otherwise it won’t work. I purchased a Samsung 1.35v DDR3 1600 SO-DIMM module along with an 840 EVO 500Gb SSD which I’ll install when I get the chance.This particular 8Gb module works for sure… I used the crucial ram tool to find out which one I needed (just google it!).

  1. First of all, you’re going to have to unscrew the back panels on these devices and for that you’re going to need an appropriate screwdriver (most of the time these use regular Phillips screws).
  2. Make sure you touch a grounded metallic object to discharge the static electricity in your body, or better-yet, use an anti-static wrist strap (it’s cheap, up to $5);
  3. (Optional, but Recommended) Disconnect the battery from the motherboard;
  4. Get yourself a pair of needle-nosed pliers. Locate the shield on the computer and notice that there are tabs sticking out at each end of the metal cover (see the pictures for details). According to David: “I took thin-nosed pliers, placed them on one of the tabs and gently pulled upwards until that corner of the cover lifted. I then did the same on the tab on the opposite corner and the cover popped off. There’s no risk of slipping, and damaging any components this way as the force is directed away from the mobo.“;
  5. You now have access to the memory slot. Place your stick in there, just make sure that the cut on the stick aligns with the nib on the slot and then gently press it in till it snaps in place. There’s literally no way to do this wrong;
  6. Once this is done, put the shield back on, reconnect the battery and power on the computer to see if the newly installed memory is recongnized;
  7. Finally, put the back panel in place and that’s it.

You shouldn’t encounter any problems while upgrading the RAM and this process should not void your warranty, as far as I know. It’s best to ask the Asus representatives in your country if that’s the case where you live though, some readers reported that Asus claims the warranty is voided by removing the back-panel, but this seems bollocks to me. I sure hope they don’t impose such a rule.

In the event the RAM does not work, you can either have a faulty (but there’s a very slight possibility of this) or an incompatible stick. So make sure to get the right module from starters. As long as you get a similarly specced RAM module to the memory already on the laptop (which is usually a DDR3 1600MHz SODIMM at 1.35V), things should go fine, but I’ve read about incompatibilities on these Asus laptops before. That’s why the best advice I could give you is to go on the forums on, search for the Owner’s Lounge for the laptop you’re planning to upgrade, and see what others have put on their machines and what worked for them, then get the exact same stick.

David tried to install a Corsair “Value Select” 8GB Module (1x8GB) DDR3 1600MHz SODIMM on his V551LB Vivobook and it didn’t work. This is advertised as a 1.5V module, while the soldered memory works at 1.35V, but that usually shouldn’t be a problem. Either way, laptop BIOS’es tend to be tricky, so it’s better to match the specs exactly. He later tried with a Kingston 4 GB 1.35V module and this one worked fine. Andrew M though, another of our readers, reported in this article that he managed to install an 8 GB 1.35V DIMM on the Vivobook V551, so if you will buy one of these lower-voltage modules, you should be able to get 12 GB of RAM on your units as well.

Anyway, that’s about it for this guide. Thanks for sticking by and I hope it has been helpful. The comments sections is open, in case you encounter any problems or want to share your results with us.

Again, big thanks to David, whose contribution made this post possible.

    Hi, I was wondering, what is the max ssd memory that I could put to replace those tiny 24GB SSD in the cache SSD memory slot ( located behind/ under the Wireless chip) because I don't want to replace my HDD,

      I don't have an exact answer to that question, but perhaps some of the other users can pitch up with a reply.

      I have Asus tp201sa. It say that it can upgrade to 8gb. But I can't find the slot memory…it's already with 4gb on board. Any suggetion?

        As far as I remember the RAM is not upgradable on that one.

    Is it possible to change or upgrade the processor of VivoBook X543 ? ( for example change Intel Celeron n4000 with a Intel Core series processors. and then upgrade the RAM )
