How much voltage?

post #1 of 4
Thread Starter 
Quick question
Coolings great on my 470's

how much voltage can I use 24/7?

I already flashed unlocked bios's onto them for 1.22v and I run them daily on 1.137v~

can I and should I go higher to the max?

I only have warranty for 1 of em though

cheers

I think the max is around 1.1v-1.15v for good air cooling if you keep temps under 90c. Do your cards have cooling for the VREGS if so your good, if not might not be good to run them up to 1.15v. H20 you can push it to ~1.2v but that a bit high and might start degrading card. Cooling is key when you start hitting 90-100c on the core other components are getting toasty and might hurt the card with high voltages such as 1.1v+. The cooler the better IMO and from what I see water cooling is best way to keep it alive with higher voltages(1.1v+).

I have a waterblock for one of em and the other has the twin frozer II cooler.

I had a peek underneath the main heatsink and there are heatsinks around the vregs and such

temps are well within safety
both cards are always >70*C unless I fire up furmark or something

If you get over 70c max temps a 1.1v should be in the safe spot.
Don't go overboard.
