I just built a 3570k on a gigabyte voltage locked board, we managed to get 4.3ghz stable of course without any change in voltage, you shouldn't need to go all the way up to 1.3!
I'll have a look at my voltage in a bit, I think it's only about 1.25.
Mine is deffo 1.25, don't know if you will be able to match it because you have a diff mobo. I didn't change anything else apart from voltage and CPU modifier
Yes, it will still post so you can get into bios
well the lower the voltage, lower the temps. Also at 1.30 you might able to run 4.5/4.6 if its stable at 1.275 at 4.4
i just bought the same board and processor, its running x44 ok on +0.005v offset. if i step it up to 46 it BOSDs on boot and at 45 it starts crashing out the odd thing when i run prime, but its not that hot (67c after 30 mins of prime)
Whats the highes ti should push the offset? as its not a fixed voltage im just a little concerned about how much it can jump. Vcore shows as high as 1.295 when i check it in windows.
