    I have some serious problems with M3A79-T Deluxe and Phenom II 920, and I think it is related to some bad motherboard settings on my part.
    I can't get the system to run stable at all, not even with stock speeds and everything (but memory voltage) on auto.

    First off, ACC and AOD isn't working well att all. After reading here I can conclude that I'm not alone with those problems, so let's skip that.

    After hours and hours of tweaking (who at Asus came up with the brilliant idea to NOT write out standard voltages in BIOS?!) i finally got the system more or less stable with the following settings:




    NB freq is about 2200MHz and mem about 950MHz (800MHz original, not 1066).

    With those speeds SuperPi 1M runs at about 20sec, from what I can read this is pretty norma for about 3.4GHz.
    However, in 3DMark i get ~ 4400p as CPU reslut which is almost 1000p less then other results at the same speed.

    Overall the performance is much worse then with my old E8400 @ 4GHz. I realize that the E8400 was considerably faster with singel and dual threads, but even in programs that favors multicores, such as 3DMark, my results were better before.
    My GFx is a GTX 260, with the old system I got about 17300p and with the new about 16400p.

    Right now I feel like I've spent ~$525 on absolutley nothing, any tips you can give me?

    You don't need to worry about voltages as much as you are. Many of the options other than vcore, vnb, and ram volts can just be left at auto. Worry about finding the overclock for your cpu before trying to overclock everything together. Try working with just the multipliers first, but remember 18x and above don't work correctly.
    Not much to say right now.
