Just built a new PC and am having a problem with the RAM. I have 6 2GB sticks and every so often, usually when the PC has been off for a while, the motherboard stops recognizing one of the sticks. I've noticed that shutting down and pushing down on one particular dimm, then restarting will usually cause the available RAM to go back up to 12GB.
The motherboard is the ASUS P6T Deluxe and I've read about a lot of people having problems with the memory on this board...but those are usually compatibility issues and that seems to not be the case here. Should I just RMA it and get a different board? Anything else I should try instead?
My apologies if this suggestion was obvious, but just in case:
When the DIMMs are inserted, make sure the side tabs are clipped all the way in to the little cutout on the DIMM at each end. Sometimes it can look in, and work, but not actually be clipped in quite properly.
Failing that, RMA, but if its common, it'll likely keep happening.

Thanks for the tip, I tried pushing them in further and they seemed to be clipped in all the way. If the problem occurs again later I guess I'll be RMAing the board. I may try to get a different one this time like the EVGA E758-A1.
Have you tried running a memtest with each stick individually? I had to troubleshoot a friends issue and manually tested each stick (1 by 1) only to find one of the sticks had errors and was causing issues.
It would still boot 95% of the time and sometimes show the correct amount of memory, sometimes not.
Your motherboard can hold DDR3 PC3-10600,DDR3 PC3-8500,DDR3 PC3-12800 with a maximum of 2GB per slot. As Gintok rightly said, test the memory stick individually and see if they are working fine. Also set the BIOS of your system.
Well the problem always seems to be fixed when I shut down and push down on the ram in slot 6. After that, the available memory goes back up to 12GB. I tried swapping different modules into that slot and the same thing occurred. Overnight, after cooling off, the module in slot 6 was no longer recognized until I pushed it in again. Although I couldn't see the RAM getting pushed in any further, it worked.
I'll try Memtest later on today to be sure. If it doesn't fail that I may actually return the memory and the motherboard to make sure the new RAM is on the compatibility list for the new board.

Thanks to everyone for your help!
Your welcome, in some cases slots can sometimes by faulty. I had a board which had a memory slot which would fail to read any memory (we tested different compatibly DIMMs in the first slot as well as another board). Had to RMA and all got fixed up in the end. Don't forget to select the most helpful answer
