Help OC' GTX580 with Afterburner - Page 2

post #11 of 22
Overvolt if you keep temps down. What's the point of putting it on water if your not gonna overvolt? You said you want to go all the way. Keep volts below 1.2v if your on water. Under 1.15v for air

Shouldn't you be able to get 1Ghz out of 580's?

Try 850 @ 1.087v first...run OCCT to check for stability, if stable shoot a little higer on the OC, once you get errors, THEN increase voltage.
Overclocking vram is unnecessary and only generates more heat.

edit: what are your temps @ that OC/Voltage?

First download funmark for stability test, then i would recommend to look online for the same configuration that you have on your system and reduce by 15% and run the stability test or Start with small increase in the Core Clock and then run funmark for a few minutes i'll say 25 min, try to increase Core, Shaders and Memory clock one at the time and try to run the test on every increment you make

For a 950 oc I needed 1.125. For 1ghz, I had to flash to a custom BIOS to unlock more volts. I was able to achieve 1ghz on 1.163. Was it worth it? To me yeah but it will void your warranty and more volts= shorter lifespan

You need the latest version of afterburner, think 210 beta 7 now.
