Heya all.

after I read the whole tread a couple of times trying to solve my own cold boot problem I suddenly realised that maybe my 12 GB Dominator 1600 Mhz got to much juice. I then sat the voltage to 1.55 and now im running strong on 0805 Bios with 12 GB 1603 mhz Dominator.

Just wanted to share my findings.
Hope it helps =)
