I went to leak test my water loop with it and the PSU wouldn't even provide enough power for the pump to run. It made a goofy sound and stopped pumping after about a minute. I thought the kit was bad so I switched to the new PSU and it worked perfectly.
I think you may be having the same problem I was having. You might be giving it 1.5v but you're not giving it the amperage it needs, and I don't know if any way to detect amperage. That's just a theory, though.

It's a brand new corsair gs600, I'm pretty sure it provides all the amps the cpu needs, if it wouldnt my cpu wouldnt be stable for benchmarking.

Thanks... I may be able to back off vcore a tad more and still remain 24/7 folding/crunching stable but I seemed to need ~1.512v to eliminate a pesky "illegal sumout" error on one core when stressing with Prime v27.7.

And yes, I have:
HT @ 2200: http://www.3dmark.com/3dm11/4739310
HT @ 2600: http://www.3dmark.com/3dm11/4941255
Those temps are just fine too.

I did the same tests and the difference was negligible on the 8350.

HT@2200 http://www.3dmark.com/3dm11/5040520

HT@2600 http://www.3dmark.com/3dm11/5040583

Just to clarify whats the stock NB speed? I just got it set to auto and its @2200. Id like to find out the stock speed so i can set it and run the tests again

Thanks man

Bumped down to 4Ghz :-( 4.2 @1.4 threw some Prime errors... stressing 4.0 @ 1.4 now. I do think it's most likely my cooler. I could throw 1.5v on my Phenom x4 and not break 50C with this cooler, it would always stay in the high 40s but this is a totally different story.

I did reseat it and also changed the thermal paste from the ZeroTherm that came with it to some AS 5 that I had around the house, though I can't really say that I notice any difference in temps. Perhaps after it's "settled in" ...

I was pleased with 4.2 on stock volts (1.4v on stock .. is that oddly high for the 8320?) but I hope it will at least hold 4Ghz...

1.425V for 4.0Ghz is way to much !!. Im P95 stable at 1.3V for 4.0Ghz.

Running P95 now:

Prime95's use as a stress test is pretty controversial on Piledriver. I'm one of the guys who thinks it isn't a good test of PD. People have PD crash in Prime95 on stock settings, and Prime95 has a history of crashing on new architectures with new instructions.

Everyone has been primarily using Intel Burn Test instead.

You have 1 GPU, I have 2. That would be a fair enough difference I guess. Who knows, I may get a higher score with even more HT speed, but my HT multi is limited to 13, so I'd have to use FSB.

Stock NB is indeed 2200Mhz.
