FAQ about Asus VivoBook X512JA RAM
How much RAM can I add to my VivoBook X512JA?
You can add up to 8GB in the single accessible slot. The laptop comes with 4GB soldered that can't be changed, so your maximum total is 12GB (4GB fixed + 8GB upgrade).
Why can't I upgrade both RAM slots?
One slot has RAM that's permanently soldered to the motherboard - it's built right into the board and can't be removed. Only the second slot accepts removable memory modules.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory running at 2666MHz. Make sure it's SODIMM (the smaller laptop size) not regular desktop DIMM. The speed code is PC4-21300 if you see that listed instead of MHz.
Will faster RAM like 3200MHz work?
Yes, faster RAM will work but it'll automatically slow down to match the 2666MHz speed your laptop supports. You won't get any performance benefit from buying faster memory, so save your money and stick with 2666MHz.
Is it worth upgrading from 4GB to 12GB?
Absolutely. Going from 4GB to 12GB makes a huge difference for multitasking, browser tabs, and general responsiveness. It's one of the best bang-for-buck upgrades you can do.
