What is wrong with my RAM?

post #1 of 17
Thread Starter 
Sometimes when I boot up instead of saying I have 12 gigs of RAM which I installed, it says it sometimes says I have 8 or 10 gigs. I have reason to suspect it may be my GPU overclock causing instability. But is it something else? Only after I do a hard shutdown does it reset and read 12 gigs.

Usually for me disappearing ram is because I've either got the QPI/VTT voltage a bit too low, or I put the heatsink on too tight (if it does see all 12 most of the time the memory & slots all work at least).

Wait what...A cpu heatsink that is on too tight can cause this?

No it can't be that because they worked fined until I added another 6 gigs

You can try 2 things.

1. Make sure you've seated the RAM in the correct slots, I got the same problem when I didn't put one of the sticks in it's correct slot

2. Make sure your CPU Cooler isn't overtightened, Because yes, it will cause RAM to "disappear"

If it worked fine till you doubled the amount the problem is the qpi/vtt voltage, bump it up until it is all good again. 12 Gb will be a bit harder on the IMC.

How exactly can he place the RAM modules on wrong slots? Like..placing the module on the graphics card slot..?!

I've had the disappearing RAM thing on a similar mobo and it was caused by over-tightening of the CPU water block. Seemingly it causes the socket to flex and some of the CPU pins don't make contact.
