Well now running on M704B_12. Not noticed any difference on the keyboard lockups, it's a bit early to say, see how it goes.
Have actually managed to get a small Overclock on.375x9 @1:1.5 = 1125
Vcore = 1.40v (24/7 stock volts for 3.6 on gigabyte & p5k) + 0.20 Over Volt Offset, giving Target
CPU Core Voltage 1.42.
Actual per v1.41
CPU-Z = 1.176v (priming smallffts) & 1.184v
So in summary :-
Target
CPU Core Voltage 1.42v Diff.
Idle .................................1.184v 0.236v
Load.................................1.176v 0.008V
Think i'll have to get the multimeter out.
Edit:
Forgot to mention I ended up flashing manually using
Ace's Bios Flashing Procedure
AWDFLASH.EXE M704B_12.BIN /e /py /sn /wb /
cd /cp /cc /cks
