On the first page of this thread you can find the link for Afterburner.. download it ,install it
When you press Reset it will tell you stock v for your card,you can also save profiles for you OC's,this way every time you crash you can go back and adjust your "Core Clock" or "Memory Clock"
If you lucky your stock on both cards will be close -very unlikely-there for i would try to OC each card separately and see how far you can go and how much v you need for desired clock
Leave Memory clock @ stock and just start bumping you Core Clock ,make your changes 10 at the time ( 830,840,850,..) every time you bump your Clock run some type of stress test (Unigine Heaven for example all the highest settings ) and watch for artifacts ,tearing ,etc
If you crash ,just bump your V by 10 (1000,1010,1020,etc) and run your test again,if it's all good go back to your Core Clock and do it again,...
Once you establish your Core Clock you can get your Memory Clock up to speed-bump it by 20 at time (you won't benefit much from high Mem. Clock) i only bump Mem. to get stutter(I mean tearing) out
Here are some of my settings; stock v963
1000v~830/1900
1038v~860/1953
1050v~910/2020


Good Luck

Loving my new 580. My only gripe is that when I have it oced to my sig specs (stock ref cooling atm) during gaming, it effectively negates the temp drop my room should be getting from the central air vent; heat wave + 580 stock cooling = gratitude to myself for
buying a kindle and plenty of books for alone time. Sometimes, gaming just isn't worth it.

first of all,i want to say ty...you guys are a blessing!!!
ok...i oced my cards one at atime using evga precision and gpuz
i was able to get both cards to 850 core and 1700 shade with temps around 67 and holding when i stress tested them with oc scanner for 10 mins...
but when i put them back in sli...the temp on the first card in the first pci e slot went to 82 pretty quick..so i stoped the test...
for some reason afterburner will not let me control the voltage..even if i chose to in the settings,however..evga e-leet will...so i checked the voltage and on the first card the voltage is...1.013..
the voltage on the second card is...1.038..
i dont know if this is why the first card is running hot or if its because there
so close together,or what...but they oc very well by them selves...but not in sli..so im stuck....

To allow for over voltage in MSI Afterburner you need to click the option in settings to enable it. Unlock voltage tuning.

will increasing the voltage of the first card bring the heat down?....
what do you think?..
or maybe new thermal past?..i dont know

No shouldn't hve to do any thermal paste on those. Unless it was applied incorrectly, reapplying thermal paste dosen't really improve temps.

Switch the bottom to the top, and top to bottom and see if that changes anything or which runs cooler on top. They'll probably run at the same temps.

Over clocking does increase GPU temps and with SLI the top card always runs hotter than the bottom. Adding more voltage also brings it even further in temps.

Do you have the fan settings to manual or auto? I use a aggressive manual fan settings for myself with a six point scale 'curve' instead of the 'steps' on the graph.

40C - 51%
50C - 62%
60C - 73%
70C - 84%
80C - 95%
90C - 100%

My GTX 580 idles around 39-41C and max temps gaming full throttle or heavy benching dosen't go past 79C-80C with my one card.

P.S. I once posted a lower setting graph (degree to point 40C-40%, 50C-50% etc) to somone who said my scale wasn't aggressive at all as he keeps his at 100% all the time.

I asked him dosen't that burn out your fan much sooner than it's life expectancy? His reply : I've been doing this for years with no problems, besides it's an EVGA with lifetime warranty, why should I care?

After that response I went up on fan % on the grid for each 10C as posted above.
