Question What RAM for this MB?

[-Charlos]

Hi guys, i got an Acer Aspire GX-281 . I'd like to buy some new ram, 16gb but I don't know the frequency my MB supports. Can you guys help me out?

You forgot to include a link to your PC, or at the very least, specs to your PC. Include that and we can move forward.

From this link:
https://www.acer.com/ac/en/US/content/model/DG.E0DAA.005

It uses DDR4 ram. You can use CPU-Z to look at the rams you currently have on your system.

It looks like you currently have DDR4-2400MHz RAM installed and your motherboard supports up to DDR4-2666MHz. With this assumption, you can find examples of 16GB kits of DDR4-2666MHz RAM here: https://www.newegg.com/p/pl?d=DDR4+2666&N=100007610 600561671 600006072&name=Desktop Memory&isdeptsrh=1

But the only way to be sure, I think, is to find your motherboard specs.

OPTION 1

Hi, the Crucial website has a system scanner tool that will detect your installed memory and suggest what kinds of memory you can upgrade to. By looking at its upgrade recommendations, you can find out what speed RAM your motherboard supports.

OPTION 2

Go to the Acer website, enter your serial number and get the exact system specs. If we're lucky, it will tell you the exact motherboard details (HP does tell you). It should also tell you what kind of memory (and speed) you can use.
