Bad DIMM?

post #1 of 7
Thread Starter 
How likely or unlikely is it for a DIMM to go out. Just wanted to ask before I spilled my guts on all the trouble shooting I have been doing.

It's 50-50 and happens all the times. Just run Memtest and let it runs few passes, don't have to do anything.

Should I try to reseat the CPU? And when I say bad DIMM, I mean the slot itself, not the memory.
post #4 of 7

If you have determined that DIMM slot is not detecting all DIMMs in it, then yes, check for bent pins and re-seat the CPU.

Its detected in that I can see the the DIMM in the BIOS and in CPU-Z, but the memory itself is not there. In other words with all sticks 3x4gb detected I still only have 8gb of memory available. When I run only two sticks in the first two channels both are detected but only one is in use. And I cannot overclock at all with a stick of ram in that slot. But without a stick in the slot my CPU will hit 4.2ghz and boot into windows and run IBT.

So is it for sure a CPU seating issue or some other issue?

If you didn't overclock the RAM and each stick is working, very likey it's the CPU seating/bent pins related issue. 3 x 4GB can run fine at 1333MHz. Or try udapting motherboard BIOS too.

The BIOS is up to date. So I will have to reseat the CPU tomorrow and see if that helps. Thank you, plus rep.
