Voltages did not change with the F9 bios.

edit: I guess my original ground was a poor choice, now getting closer readings.

        bios   idle   load
vcore	1.400  1.387  1.380
pll	1.450  1.455  1.501
	1.500  1.557  1.604
	1.570  1.578  1.623

vtt	1.300  1.308  1.311
vdimm	2.200  2.215  2.207

excellent voltage readings . just one question; do you have the voltage settings at auto? i still don't understand why the PLL voltage slightly increases during load. try to hard set or type in the nominal values instead of leaving the other voltages on auto.

i'll try to get a reading on mine later then compare it here. i have all the voltages hard set and the only ones on auto are DIMM reference and GTL reference. BIOS version is F11, btw. (F11 seems to handle GTL ref very well at auto, i spent days tweaking GTL reference settings with F9).

edit: were you using a fan header (ground) as your ground on the readings?
