Hi,
I just put an i7 920 computer together today and found that I can't run prime95 stable at 3Ghz (I was planning to overclock to 3.6Ghz!). Anyway, I am able to run prime95 at 2.9Ghz and the load temperature peaks at 74 degree C.

Here is my computer specs
CPU: i7 920
MB: Asus P6T
RAM: OCZ Platinum 6GB Triple Channel DDR3-1600
Cooler: TRUE
VCard: HD 4890
Case: CM 690

Here are the current voltage settings:
CPU: 1.35V
QPI/DRAM: 1.35V
DRAM Bus: 1.64V
CPU PLL: 1.96V
Everything else is set as auto

Could someone please advice what to do? I am very disappointed with my system!
Regards,
James

Reseat heatsink and CPU PLL seems very high. Lower that down to 1.88 or 1.86.

Did you apply the thermal grease correctly?
