Question Upgrading RAM?

[gganault]

Hello,

Before I order new RAM, I wanted to make sure it'll work.

The AMD-powered ASRock A75M-ITX mobo in my — aging but good enough for my use — workstation currently has two, 2GB DDR3 DIMM @ 665MHz (9-9-9-24) for a grand total of 4GB.

According to the page above, the mobo supports "DDR3 2400+(OC)/1866/1600/1333/1066/800 non-ECC, un-buffered memory" for a "Max. capacity of system memory: 16GB*.

So I'm thining of getting two 8GB 1866 from this seller:

Alternatively, are those below also incompatible with the A75M-ITX mobo:

• "Cannot be compatible with A55, A75, A85, FM1, FM2 series motherboards" https://www.aliexpress.com/item/33028400883.html
• "can't compatible with A55, A75, A85, FM1, FM2 series motherboard." https://www.aliexpress.com/item/32222077805.html

Thank you.

It needs to be 2Rx8, memory modules, based on sixteen 512M x 8-bit FBGA components per module (double sided chips)
Your QVL is here :https://www.asrock.com/mb/AMD/A75M-ITX/#Memory. Never bought that Killisre from China

here is some Kingston that is on your QVL https://www.ebay.com/c/151886800

Thanks. I'll get 2x8GB from that vendor in China, and report back in a few weeks.

I have bought from AliExpress before but just modified Xenon 771 CPU's for 775 boards with no issues,but don't buy no name video cards from them from what I what I heard.

I received and installed two of the following RAM modules:

VEINEDA DDR3 4 GB Memoria Ram 1333 1600MHz
https://www.aliexpress.com/item/33029470958.html

Speccy does say that I now have 8GB, and the computer does feel faster:
8,00GB DDR3 @ 665MHz (9-9-9-24)

What's odd, however, is that the original modules from Corsair say that they were 4GB each for a total of 8GB, although Speccy reported this:

4GB DDR3 @ 665MHz (9-9-9-24)
=> On the stickers, it says "Corsair xms3 1600MHz 4GB (2x2GB) 8-8-8-24 1,65V"

Could it be that the Corsair weren't fully compatible with the ASRock A75M-ITX mobo?

… or that the modules were always sold in pairs, and the stickers are correct in that respect?

Thank you.

Regardless, 32-bit Windows 7 can only use up to 4GB, so those extra 4GB are unavailable and marked as "Hardware Reserved" in Resource Monitor :-/ I should have checked before.

I'll get a new computer when I have the courage of migrating the whole thing.
