I have an i7 3820 in a cooling loop with a GTX670 FTW cooled by a 360 rad and decided I may as well OC the CPU as I have the headroom, went with the following settings:
Multiplier: 36 (stock)
Turbo: Disabled
EIST: Enabled
BCLK: 100
BCLK strap: 1.25
VCORE voltage: 1.35v
VCSSA voltage: 1.1
Load line calibration: High
130% current capability
Other settings on stock
This was after some testing with prime (once temps had plateaued)
Under gaming neither CPU or GPU exceed 50's.
