Windows 7 64 bit not recognizing all 8gb or ram? - Page 2

post #11 of 26
unlikely but possible. improper heatsink pressure can cause it to become misaligned as well. wouldn't hurt anything to pull it and reseat and reapply thermal paste.

If the CPU is out, how could the BIOS and CPUz still recognize it?
post #13 of 26
because its a new design. its a common problem with the new i-cores. not sure on how to exactly explain it though. but they took a page from amd and put the memory controllers on-die so the memory compatibility and speeds are tied to the cpu now. so even though the cpu is seated and what not its common for the pins that control the memory to not make perfect contact and not fully recognize your ram

So... even if the CPU can't see the mem, the BIOS and CPUZ can?

ya its kinda ****ed up i know. i've had it happen to a few computer systems i've built for clients. bios and cpuz show full ram installed but windows doesn't. i've had it where bios and windows don't see full ram but cpuz does. only had these issues with the i-cores

On my board when my overclocks are borderline unstable only part of my memory boots up too. Try backing your overclocks down and that might resolve this.

You fixed it by reseating everything?

how many sticks is it 1,2,3,4?
if one just reseat that and the cpu the new tiny pins on the motherboard that touch the cpu can be a pita go into the bios load defaults and then change only the settings you need to boot. restart and see if windows sees it.
now if you have multiple like say 4 start with 1 2 gig stick boot see if it sees 2 gigs then 4 then 6 then 8
if 2 sticks then it would see 4 then 8

now if that all checks out and you had to change any other settings in the bios for "better performance" or anything like that do them 1 at a time reboot and see if anything changes.

long process but this should make the issue rear its head

I have a 4x2gb set, I will try that.
