P6T V2 build 1003
3x2 OCZ Gold 1600
3x2 Corsair Dominator 1600
(RMA'd the OCZ while I had the dominator, and since they are both the exact same timings, I put them together, and they passed 10 hours of memtest at 1604mhz 8-8-8-24-6-88 1T)
SB Fatal1ty CS
LCLC, 4x120mm fans, 1x80mm
OC bclk to 160
It's all very stable and good temps, I've tested it tons with prime95, OCCT, memtest, Unigine.
I just rebooted 2 more times and both times its reading 12gb again on windows.
It's almost like it's a short or something..
I have pulled out and replaced the ram even after i made SURE they were in firmly.
Sometimes I boot up with 10gb, then i just reboot again and it shows 12gb.
I've tried changing from XMP to manual entry also, and tried seting the UCLK to 32XX instead of auto.
Voltage is 1.66
