    Re: a mild i7-860 OC that would last?

    Still doing it...

    Last resort: Bump up the PCH to 1.1v. If I still boot to the recovery environment, it's RMA time.

    Nope. Just got a "BOOTMGR image is corrupt. The system cannot boot" message again. Good news is that it isn't booting to the recovery environment anymore.

    What's the clue? Bad RAM? what part is going wrong?

    Mind you, no errors really happen during use, but when I startup, it's a game where some days it happens and sometimes it doesn't.

    Do you have another system to troubleshoot parts with?

    I'd run some MemTest86+ cycles on the memory individually.

    This is my only DDR3 system. I'll only have time to test individual modules on the weekend, and it's kind of hard to take out module slot #3 without the CPU 120mm fan getting in the way.

    However, on data corruption cases in the past, it passes memtest86+, only to BSOD when data is being transferred from HDD to HDD.

    Is all you're getting now is POST and error?

    Re: a mild i7-860 OC that would last?

    At 11-11-11-29 1T 1.7V, the modules sometimes POST fine all the way through the boot, but sometimes it just goes and does a "BOOTMGR image is corrupt".

    Anyways, got the go ahead for an RMA from Corsair, awaiting my RMA # and mailing label.

    Re: a mild i7-860 OC that would last?

    Update:

    Got the new sticks and a symptom from before still happens on these sticks:

    If I manually set any timings, the system will BSOD.

    Therefore, I'm running at DDR3-1333 11-11-11-29 1T 1.65v with the Dummy OC feature on. DDR3-1600 needs a lot of voltage, and that's what I'm not ready for.

    Vcore is 1.2v, VTT is 1.25v, BCLK is 166x21.

    Dang Jack.. I give ya props for persistence. You've been at this nearly a year now! Wish I could have been more help. I just decommissioned my i7-860 setup. Good luck to ya mate!

    Re: a mild i7-860 OC that would last?

    It was never perfect, I couldn't really figure it out... Now it's down to memory timings and voltage. Stock works for Stock, but once I OC, I had to loosen timings to prevent BSODs.

    Reverted VTT back to 1.2v from 1.25v... It's not that anything went wrong, I just wanted to see if this had any effect. (though, even with a higher VTT to counter tighter timings, Tight timings and BSODs still wouldn't cooperate.)

    lol So it's like you pushed the rig to it's limits and something crapped out. Now it's back to good old stock settings.

    Re: a mild i7-860 OC that would last?

    Nope, I'm at 3.5Ghz with DDR3-1333.

    I also turned on a BIOS feature that does extra checks during POST: Dummy OC. It means a longer startup, but it's extra insurance.

    I have not encountered the BOOTMGR error ever since I chose to run at DDR3-1333, but in case I do, I'll post again.

    Re: a mild i7-860 OC that would last?

    Confidence gone. Just BSODed. Raising VTT back to 1.25v. It was a dxgmms1 BSOD.

    Edit: Kinda found out why 1.2v BIOS set VTT didn't work. The VTT droops on my board by 0.3v from it's BIOS setting. That would in fact mean running it on 1.17V VTT when it was supposed to be 1.2v. At 1.17 and 166 BCLK, it hit it's hard limit and commited digital suicide with a BSOD. Currently, 1.25v droops to 1.22v.

    Also increased BIOS RAM voltage to 1.67v, since someone with the same board needed that much to really get 1.65v to his RAM.

    Vcore should be fine at 1.2v, it increases to 1.223v under load.

    Re: a mild i7-860 OC that would last?

    Urgh... After cold booting from heavy load, boot is successful, but a critical exe failed to load during logon.

    When I tried to shut down or log off then logon, Windows just throws a RPC error.

    Raising VTT to 1.275v. Have I hit a BCLK hole at 166?

    Edit: Now to the good news: 1.275v VTT has not resulted in a Windows freakout after a cold boot from shutting down from heavy load and leaving the system off for a few hours... For now. Will post again if it's still freaking out.

    Re: a mild i7-860 OC that would last?

    Well... after my home's circuit breaker tripped again for some unknown reason, (while my machine was on) trying to chkdsk the SSD later has just resulted in the Recovery crap returning!!!!

    I'm almost at the point of giving up... and I'm almost at the point where all of you are about to say "I no longer care about this, screw him."

    One last VTT bump to 1.3v. If I still get problems, I'm giving up and returning to stock.

    Update: I've gone 2 days stable, the only snafu was when I tried to tighten timings and the machine TDRed while playing Just Cause 2. Even 10-10-10-29 1T is too tight.
