Here's a view of the voltage discrepancy I'm getting. the left side is HWmonitor (Aida64 and pretty much any other monitoring software I've seen shows the same odd voltages), and the right is Easytune6. I'd guess Easytune6 is correct, but it seems odd, as if the sensor was shot, all voltages should be off.
Edit: I realized how Easytune was able to force 4200 turbo, it changes the p1 state (which is normally 20.5x) to 21x. The 990fxa-ud3 seems to prevent my fx8350 from ever going into p0 (legitimate 21x). Really wishing I had just bought another board, the amount of uncertainties with this $140 bucks worth of metal is giving me quite the headache.
Edit 2: Ran some test after uninstalling Easytune. Using AMD PScheck, my fx8350 does go into p0, just very rarely, and so quickly that most apps like CPU-Z don't update in time to show it. From some videos I've seen it should be happening WAY more. Apparently some Asus boards have this problem as well.Edited by aquagene - 4/19/13 at 5:58am
