Just built new I7 rig, instant 4.0ghz overclock, just a couple of question.

I've just built the rig as per the specs to the left. It was a lovely smooth build, with everything working first time.

My I7 is under a Corsair H50 cooler, and core temps do not go over 69C, with CPU temp max at 55C so temps are good too.

Basically to overclock I set BLCK to 190, multiplier at 21, CPU voltage to 1.3V (1.28 idle / 1.265 Load actual) and ram at 1.66V with Corsair recommended timings of 9-9-9-24. I left the rest of the voltages at auto.

LLC and Hyperthreading is enabled and Turbo mode is off.

This passed 50 runs of standard IntelBurnTest with 8 threads and 8 hours of Prime.

If I drop CPU Voltage to 1.2750 in bios the PC will crash under Burntest within 2-3 runs.

Should I up the voltage from 1.3 in bios as it is so close to an unstable voltage or should I just leave it as is? Is it ok just to leave the rest of the voltages at their auto setting, or should the board maintain safe voltages in other words?

If it works then leave it as it is.

your running the same Bios setup as me and i've had no issues
you just loose a bit on the ram thats all.

windows shows it at 3.8ghz for some odd reason
