X58A-UD3R V 2 Bios FE
Win 7 64 Home Pemium
i7 930 o'c 3.885, watercooled EK HF 1.344V, Bus speed 185, Multiplier X21, QPI 3330.0
GEIL 6 X 2Gb 2200 @ 1480 MHz 9-10-9-28 1.66V
2 X XFX HD6870 in Crossfire GPU 935, memory 1100, Catalyst 10.12
Rocketfish 900W modular
2 X 640 Caviar Blacks in Raid 0
I've had this setup running at 4.2 MHz but it over heated when running Prime 95 or Intel Burn Test until I added the EK watercooling . The EK solved the over heats but it still remained unstable. So I kept lowering the bus speed. Now I'm getting BSODs, random lockups, and failures to boot.
MemTest has been run with no failures on each individual Ram stick.
Catalyst drivers wouldn't cause the boot failure. They have caused lockups but not usually BSODs
One reboot failed to find the drives. Yes the raid was in force in the bios.
Another boot stopped after the Ram test.
Any suggestions?
Regards Nigel
