Overclock 580 Sli's...

post #1 of 4
Thread Starter 
First of all, thanks everyone for being such a help with all my questions! Next, I just got 2x580's and I'm wondering what the basics I should be shooting for when overclocking them via EVGA precision. I would appreciate any advice since I don't want to screw them up!

Slowly bump the clocks while testing stability. Bump them like 5-10 MHz then check stability. Take GPU tool or OCCT and run the test; if you're getting artifacts/errors you're going too high.

in the case of artifacts or errors then increasing voltage will generally solve the problem to an extent. As soon as you find an oc that is just barely unstable add some more voltage then add mhz until it is unstable again. Just rinse and repeat until wanted oc. Most ocs over 900core will need watercooling tho depending on what voltage the card requires

i have my SLI GTX 580 900/1800/4200, VOLTAGE 1.088V MAX LOAD 67C ON AIR BOTH EVGA BRAND. Try my setting and see if you can get them stable. Do not rely on benchmark tool for videogames, try playing different games like crysis, just cause 2, BC2 etc. You will notice that your card might be stable running heaven or 3dmark but not stable in games.
