12GB installed, 64-bit OS, only 4GB usable

Hey guys,

I have an issue with my PC. Specs in sig.

Windows 8 64-bit bit is saying on 4 GB is available of 12GB installed. RAM is showing up fine in CPU-Z.

Any ideas? Thanks

Sorry about the size

too tight a cpu cooler,or bent cpu socket pins can cause that

test with one ram stick and test one ram slot at a time,you need to find which slots arnt booting,then repeat the test with the other ram sticks just incase any sticks are faulty

Hmm, the CPU cooler hasn't been moved in a while. It's a water block. Will go through the RAM slowly and see what comes up.

Maybe just check in Msconfig Boot tab, Advanced options, Maximum memory is unticked.

It would appear, that 2 of the sticks have died.

did you test the same slot with a working stick? if so you need to rma the whole kit for replacement

I removed the other 2 sticks, booted the PC, it was fine. Replaced the first stick, and it wouldn't boot. So yeah, a bit annoying!

Going to sort the RMA with Corsair tomorrow, need to take the RAM out of the PC to get all the codes.
