Has the default memory controller voltage been reduced in BIOS ver F6? I am pretty sure the default was 1.3 in F5, but it is 1.187 in F6. Can anyone confirm the F5 default for the Memory Controller Voltage? B.T.W. I took the measurement off AMD Power Monitor. The reason I am asking is that I routinely undervolted it in F5 and earlier by 0.200 volts, but when I did this in F6 it would not get through POST. However when I reset it and then undervolted it to 0.100 volts I got it to boot cleanly.
