Thread: Bios settings for i7 920 D0 @3.8

I built my rig the other day as well as did a little investigate on the web about overclocking the i7 920 as well as went ahead and did so @ 3.66 GHz (allegedly the sweet spot). I have the D0 revision i7 920, the rest of hardware is in Sig. I just required to ask you people if there are any bios settings I should change.

AI Overclockers Tuner: [Manual]
CPU Ratio: [20]
Speed-step: [disabled]
BLCK Frequency: [183]-or[190]
PCIE Frequency: [100]
DRAM Frequency: [DDR3-1467 MHz] [not sure i think 1500 something]
UCLK Frequency: [Auto]-Should I change this to highest?
QPI Link Data Rate: [Auto] -Should I change this also?

DRAM Settings:
7-7-7-24

DRAM CAS # Latency: [7 DRAM Clock]
DRAM RAS # to CAS # Delay: [7 DRAM Clock]
DRAM RAS # PRE Time: [24 DRAM Clock]
Everything else in RAM settings [Auto]

Voltages:
Vcore [1.175]--I think i could go lower, stable at this tho [1.20] for 3.8
CPU PLL Voltage: [Auto]
QPI/DRAM Core Voltage: [1.25] --changed this 2 [1.20]
DRAM Bus: [1.64]
CPU PLL: [1.82]
Rest on auto

CIE Support: [Disabled]
Load-Line Calibration: [Auto]
CPU Differential Amplitude: [Auto]
CPU Clock Skew: [Auto]
CPU Spread Spectrum: [Disabled]
IOH Clock Skew: [Auto]
PCIE Spread Spectrum: [Disabled]
Hyperthreading: [Disabled]-no performance gain in games as of yet. + it adds 5-10c more...


Well with these setting's its Prime 95 small stable during the night, haven't tried longer also passed 4 hrs OCCT . Temps Idle 40-50 load 68c max, well let me know what you think, Thanks

I've seen clients with 1.25vcore as well as hitting 4GHz if that’s what you are aiming for. Good job man. I think that RAM is helping a lot too because those are great settings.

Go for 4GHz! I have mainly the similar core system, got 4GHz on 1.23Vcore; you may be able to get it somewhat lower though. Not that it matters, but it will bring your RAM up to a nice pretty 1600.

I wouldn't be anxious about shortening the life, as long as you keep the temperatures in check.
