Make sure you have SP1 installed on win7. On p95 blend is the only one worth running imo.

Run it for 6 hours and keep an eye out for failed workers. My first OC failed a worker around 4 hours, and my current one ran for 24 hours error free. A half hour at a time doesn't really prove stability, it just gives you an idea where your load temp will be.

I have found so far if you can pass test 1 your cpu voltage is good. Failed worker is low ram voltage.

Have you gotten it to post at 39x125?

What do you mean by "passing test 1" ? And how else does prime fail besides dropping a worker? If it drops a worker, it means there was an error, and an error means a stability problem. How would you know what voltage caused the failure? Is this your theory or is this a fact that can be backed up with a link?

I've gotten it up to 40X multiplier 5.0ghz stable but the voltage was way too high for comfort.
Considering I'm on air using a old Vigor Vigor Monsoon III LT designed for a 1366 processor I don't have much to play with heat wise.

Edit:

Seems to be stable after a few hours of testing. @ 4.8ghz at 1.315 voltage.
368
I'm done testing it as it passes Cruncher, Intel burn test and Prime 95 for multiple hours.

If it doesn't crash during any of those test I'm pretty sure gaming and converting clips from my camera won't touch it.
All is well so far lets hope it stays that way. thumb.gif

how many tests at a time are you guys running in prime? i run blend with 8 tests at time but for some reason as soon as i change the BCLK to get over 4.3 i will fail like 2 of the 8 after 2 hours or so but the other 6 will run fine for 12+ hours. i cant get it to stop failing no matter how much voltage i give it. ive gone up to like 1.4 on 4.5 and it still fails the tests. cant figure out the issue.

When you are changing the BCLK check that it is not changing your ram speed .
