Hi Guys,

No matter what I try my GTX 470's voltage won't change, I have tried at least 5 versions of afterburner and the slider to change the voltage is still grayed out.

Anyone know of anything else that can be used to change the voltage?

go unto the settings, icon at the bottom right corner of afterburner....in one of the tabs you will find a box to unlock voltage control, check it, save it, restart afterburner;)

all of it...lol. Depends on the PSU and if it helps the clocks get stable. but yeah I maxed it with tri SLI and the temps were acceptable. Wouldnt run 24/7 with it personally, at least till I go water. Hope that helps even thos its sort of all over the place.

one more thing....go to the fan profile....

move the low point to 0% fan at 0*C then have it got 100% at 80*C, should help temps a bit.

all of it

All of the manufacturers say the card will allow for the full slider, but I will say you do need to set a better fan profile, or it will overheat and crash.

I ran Tri-SLI with all 3 maxed;)
