My problem for the last six months has involved memory. When I first build this system my memory wasn't consistently registering 6GB. It would freeze and automatically restart. When it would reboot it would either recognize 4GB or 6GB of memory. After a while it ticked me off so I RMAed my board. Gigabyte replaces my board and I'm still having the same problem. Now its either the CPU or the memory. The memory is fine and I've tested it on another system. I contacted Intel and they said my settings for my memory could be off. For some reason my mobo puts the ram speed at 1066 rather than 1600. (8-8-8-24) 1.65V Intel told me it could be my voltages. Now I don't know what to do from here, and I'm not sure if I should even touch the voltages for the ram. Should I rma my cpu?

RMA the CPU could not solve the problem.
Set all the specs of ur RAM manually in the BIOS BUT don't rise the voltage more that 1.65V. After that run memtest86+ and Prime 95 or SuperPI
The RAM frequency defaults to 1066. You have to change BIOS yourself to get it faster. As saint said, set the specs manually in BIOS.
