I am currently use EasyTune 6 verison B9.0316.1 2009/03/17 link at GIGABYTE - Support&Download - Motherboard - Utility - GA-EP45-UD3R (rev. 1.1)

Maybe I like to share with you for ET6 tips pix below you get an idea.

pix 2 "see CPU Vcore" 1.45 that is so high while I overclock so I notch down to 1.3 after.

I think 4 highlights that really need changes the mostly and others the rest should be auto since they do not changes anything even overclock.

Pix below.

Hope it help
