flash bios using @bios in windows (dont forgat uncheck checboxes, or program crash)
boot windows with new bios then shut down comp.
connect a ps/2 keyboard.
push power button then push alt button on keyboard dont drop button and spam to F12 button.
bios will ask you: flash backup bios with your main bios. flash it
and your bios will never come back to f3.

are you sure about you cpu can hit 5.3ghz+ ? used same cpu on asus board?
Tried with F7f bios but no change.
Thanks for the hint on updating the backup bios
Yea this same CPU does 5.3 in the Asus, also the CPU I have now in the Asus has been tried in the UD4 and I had the same issue on the UD4

I have ordered another UD4 which will be here tomorrow so I will try that next. If I get the same issue then I will be stuck, but i suspect the second board will just work as it should.
