soundood,

Overclocking is NOT guaranteed. You are adjusting the sliders at your own risk. Initially it seemed that you wanted to try and solve the issues you are having, is that still the case?

1) the reason I asked to try at default BIOS settings was to check if CPU VID / CPU NB VID work OK this way
2) HT ref. clock slider has proven the root cause for various issues, extra details on how this works on that mobo would be useful

Also, does CoolNQuiet work OK on your board - do you see CPU multiplier and Voltage jump and and down based on load when CnQ is enabled? This is exactly the same thing as adjusting CPU Multiplier and CPU VID thru AOD.

One possibility is that you just have a bad board. BIOS corruption might hint into that direction (I dont see anyone else complaining about BIOS corruption, do you?).
