MSI GTX580 3GB LIGHTING EXTREME Vcore - Page 2

post #11 of 27
From what I read with the gtx 500 cards, I dont think you should risk going over 1.1v. Stock can be anything from 0.9 to 1.037v

Theres no set amount of extra voltage you need to become stable, all cards are different.

Yes you do, your going to need around +30 for 2200, mine do 2450 both cards at stock voltage, but all cards are different.

^Possibly, When I overclokc my graphics card I tend to leave the memory clocks and just go for core clocks though.

aux voltage is PLL, usually overclocking aux/pll has no gain but sometimes it helps with cards (like the one you seem to have), try it out and report.
