    Hold that thought. The VDDA does work, my copy of orthos just got corrupted. I downloaded the version of prime from the link KTE provided, and its just about to finish 10k fft's at these settings...

    HTT=255
    CPU=11.5x
    NB=9x
    HT-LINK=1.8ghz

    vCore=1.3, 1.28 actual
    CPU VDDA=2.8v
    vCPU-NB=1.3v
    vNB=Auto

    Well guys, it looks like I finally figured out the problem after all. I think that because of the cold the bios set the VDDA lower than it did while it was on air cooling, causing me to not get the overclocks I did on air. If this goes for at least two hours, I'll just take a screenshot then so you guys get one finally. Maybe now it will clock higher...one can only hope.

    Edit: It froze when it got to the 14k fft's, so I decided to set the vNB to 1.3v and try again. Its currently halfway through 12k so I'm just gonna hope now.

    Edit 2: I hoped, and it worked. now its about halfway through 14k's and going. I have a quick question though, what's the maximum voltage you guys can give the nb on your boards. Mine maxes out at 1.4v and was wondering if any of you guys had the option of going higher, like to 1.5v. Since the nb is on the chip and not the mobo I thought that a little extra wouldn't hurt since its at such low temps anyway.

    Not much to say right now.

    Oldguy932: Can you show us what temps AOD picks up idle or load?
    AOD works subzero, I have it confirmed and have it working subzero myself. That speedfan pic is confusing because it's manually configurable and doesn't show those readings on my Phenom but 4 core readings instead.

    Should be 2.5V stock and is a CPU component voltage. Not sure what it does, we don't have it on this board. Vdd is only a term applied to standing for positive voltage at FET terminals though, so must be linked.

    Did'nt I link it in your thread earlier?

    Here it is if I didn't: http://www.amd.com/us-en/assets/cont...docs/31412.pdf

    Keep it going till 8 or so hours. Then switch it off and before doing so, capture the screenshot. Then leave it running, bench it etc and most importantly, let it idle. If you've read the thread earlier, you'll see my BE can do 2832MHz stock HSF and pass stability but it's still unstable because it will randomly freeze when idling or have one or two bootup issues. Others have similar issues. If your chip could bench 3060 on air, 2.93G should be air stable because voltage is too low for it not to be.

    You keep missing answering my one qs
    I'm going to repeat it again, I know you can read.

    We can't control vIMC, that's why you see sub-2.6G oc's at 1.23V.

    The minute someone on this board can and I'm hoping MSI has included the option in the upcoming 3 BIOSes, then you'll no doubt see higher oc's/stability. The NB maxes out quicker than everything on Phenom if its at stock volts. So far everyone on this board runs Phenom at stock vIMC volts but the guys with a 9600 BE.

    I've tried Asus M3A32-MVP Deluxe before. It can run vCPU NB upto 1.6875V, same as VCore, although I tested with an X2 5000+ BE instead so the options will be different for Phenom. It has far more voltage/speed options in the BIOS than the MSI BIOS. In fact, I may pick up one for a few days just to compare.
