Ugh, I have a POS i920 that is highly unstable. Frequent BSOD no matter what I do.

Asus P6T Deluxe V2
i920 D0 3919A509

CPU Ratio: 21
Speed step: enable
BLCK: 180
DRAM: 1443 MHz
CPU: 1.23125v
PLL: 1.86
QPI: 1.35
IOH volts: 1.20
DRAM volts: 1.66
CPU/PCIE spread spectrum: disabled
C1E: Enabled
C-State: Enabled

Under load it runs in the mid to upper 70s. The system can last anywhere from a few minutes to a few hours before BSOD. Extremely frustrating.

Ideas?
