First my specs:
i7 920 @ 4.0GHz
3R Systems Prima Boss II 120mm CPU cooler
Asus Rampage 2 Extreme
12Gb GSkill DDR3 12800
Palit 4870X2 Revolution in CF
150Gb WD Raptor
300Gb WD VelociRaptor
1000Gb * 2 WD Caviar Black
1000W NC Top
Heroichi Cougar Big Tower
Windows 7 Ultimate RTM x64
I recently upgraded MB, RAM and CPU two months ago (new). After clean install of Windows 7 everything was working just great!
This afternoon, CPU meter in sidebar, system performance info (in control panel) and BIOS shows 8Gb! Funnily enough CPUz still shows 12Gb.
Removing 3 channels of memory and rebooting resulted in....NOTHING. No beeps, no BIOS posts-just a black screen with a "locked" message on the BIOS LED.
Trying 1 stick, 2 sticks, 3 sticks (in combo) resulted in the same result-NOTHING. 4 sticks worked but showed up as 4Gb, 5 sticks 6Gb ad 6 sticks 8Gb. Clearing CMOS faired the same results.
I have OCd the CPU to 4.0GHz WITHOUT altering voltages (all settings on auto)
What could be the problem? Bad sticks?
Thanks in advance!
