    Just be prepared because you might have to go up to +.05mv over initial
    to make it 100% stable. But don't loose any sleep over it, it will be fine.
    Once it's done with burn-in it will remain stable.

    CPU-Z shows that I am running 4.2GHz at 1.408V on watercooling. I'm on a Striker II Extreme 790i Ultra board. How safe exactly is 1.4V on an E8400? I'm very, very new to these 45nm cpus.

    Thank you, thank you very much. My temps are 30C on both cores with the voltages. I knew the temps are okay but I wasn't sure if it could handle the voltage. cheers.

    I oc'd my e8400 to 4.5 to 4.7 on air when i got it, loosening my ram timings to maximums. I let the voltage go to 1.5V real @ Load during benching, then tried to stress test with orthos @ 4.5ghz 1.42V. I settled for 4.2ghz @ 1.38V real for normal usage. I guess that was my burnin process...

    I see -- you didn't keep lowering the voltage and stressing?

    yes when i stayed at 4.2g, i played around with various combinations from 445mhz x 9 [4050] and up. at 4.2g i started with 1.424 Vcore load and kept going down until i found 1.38v to be the lowest possible before i would keep crashing.

    1.38 took about 1.45V in the bios on my ip35E
