the bios sets the auto vcore to 1.475V

is this ok? the pcu specs are 1.40 max.

i will appreciate it if someone can post all the voltages i should be using at stock.
thank you

I've noticed the same thing. I thought flashing the bios to the latest FD version ould help, but this made no difference. For now I've manually set the voltage to 1.35 in the bios and have not noticed any issues, though I have yet to try it out with the Turboboost feature. It might be that the 1.475 volt value is really maximum that will be used for Turboboost and that the value used under other conditions will be less. It would be nice if Gigabyte would explain what they are doing.

I've previously noticed that my ASUS M3A-78T seemed to overvolt the Phenom 9850BEby about 0.1 volt. It could be that the motherboard makers have a strategy of overvolting cpus to facilitate overclocking, but I would prefer not having that as a default condition.

Further experimentation indicates that the 1.475 V Vcore sectting is used only in the Turboboost mode. If my experience is anything to go by, for operation at stock speeds, one can probably drop the Vcore setting in the bios by .05 volt or more.
