ux510 RAM module upgrade heatspreader

Hi,

I have the asus ux510 zenbook. Which has 8GB ram but is marked as "upgradable".

So, I got a 8Gb SoDIMM module and opened up my laptop. All the guides were great until I tried to find the RAM-slot.

There is a aluminium casing with the inscription "ux510 DIMM heat spreader" but it appears to be soldered to the mainboard and blocked by the heatsink.

No guide is talking about this, to avoid the risk of damaging any component I contacted support but they didn't really respond on how to get behind this metal box. Has someone experience with upgrading this laptop of a simular heatsink ?

Asus said "google it" and "we don't limit adding RAM in this model".

After a while I discovered there are little tabs holding the heat-shield in place. I opened them a bit by a very tiny screwdriver. After removing the cable that is taped to it, I could lift it by placing a screwdriver under it. And lo behold, a DIMM-connector.

The 8GB SODIMM 2133Mhz RAM I installed now showed up perfectly in Windows.

Boy they hid it well!

Now we can see the little dots around the edge where not the legs of RAM components which is what lead me to beleave the RAM was soldered. So I guess the base RAM is on the other side of the logic board.

Happy it all worked out!

If your upto it, how about taking some more pics showing your process of opening the system and how you got the cover lifted and make a IFIXIT guide for the next person. Helping others with your discovery ;-}

From your image and what I can also find on the web this is confusing! At is implies there is the option of adding additional RAM.

From their website: “DDR4 2133MHz SDRAM, 1 x SO-DIMM socket for expansion, up to 16 GB SDRAM”

Clearly this model has 8 GB of soldered of RAM (DDR4 2133MHz SDRAM) which is likely located under the shield given the limited view of your image. There should be a DIMM slot nearby (1 x SO-DIMM socket for expansion). Based on the description, but I don’t see it. If you peel back the tape does that offer a clue?

Looking at this repair guide which I found: Service Manual - ASUS Zenbook UX501VW. There appears to be two versions of the logic board! Your image does not show the signs of a socket where this manual shows one.

‘’’So... What to do to fix this?’’’ First I think you’ll need to talk with ASUS on getting clearification on what the web site shows (and hopefully your users guide as well) and the fact the model they sold you does not offer the option to expand the RAM. You’ll need to see what they will do to rectify this either giving you your money back of offer exchanging it for the 16GB model.

If that fails you’ll need to talk with your local consumer protection agency or if that’s not an option speak to a lawyer. Make sure you have all of your paperwork of your purchase and take notes of all your calls and what was stated (record them if you can) as that may help you later.

@danj That manual is for a different model laptop. So it makes sense that ASUS has used a different board.

Yes George, I’m aware this is a older version of the system, it was for reference on how ASUS designs things. Very often companies re-use a logic board design or alter it slightly, this is independent of the chips they use.

What threw me was looking along the edge seeing the little dots thinking these where the legs of SMT mounted RAM chips and their support chips. Still an odd layout, they must be via’s from the ground plain to extend the sheilding upto the metal RF shield covering the SIMM sockets RAM module.

I agree. It is an odd way to do things.

Check the opposite side of the board. I would imagine that that's the heat spreader for the pre-installed RAM. Often manufacturers will do that.
