some systems can be really weird with ram, if its possible its always best to go with a brand/make/model/speed recommended by the manufacture if they're providing such a list but usually I find you'll only get such a detailed list of ram from high end desktop motherboards and thats if you're lucky.

I did a job for a client with some weird re-branded boutique gaming laptop that was bluescreen crashing due to bad ram. The damn thing had zero documentation to work with so all I could do was work with the exact type/speed of ram that laptop came with but it also had generic no name brand ram in it so I just went with whats usually a solid option, crucial ram.

two sticks of 16gb (she def didnt need this much ram since all she did was excel work but she wanted it).

Only one of her sticks of ram was reporting as bad, but she wanted to get two of the same to ensure compatibility which isnt bad a idea but usually not necessary.

I installed both new sticks of ram and ran mem tests again. its still getting an error. I put the one good-old stick of ram back in and ran the tests again twice, once with the known good old stick of ram in both slots and it came back with no errors so I know the slots are good.

I put one stick of the new ram in, mem-test came back good. put both sticks in, mem-test came back failed. that means the last new stick I put in must be a doa stick stick right? wrong. I tested the last stick I put in by its self and the mem tests passed. wtf

put them both in but swapped the slots, fails again.

I put in one of hte old sticks and one of the new sticks.. it passes. i run these tests several times. makes no god damn sense. all the ram is good, both the slots are good, i just didnt like both new sticks installed at the same time for some reason.
