GTX 580 OC

[Ticonderoga]

So I pulled the trigger and got my secondhand EVGA GTX580 SC. Since I am going to be watercooling it I am looking to OC it.
I am hoping for something like 900-950 on the core, but what should I be aiming at with the memory and vcore? How much volt can I give the GPU without decreasing its lifespan too much?
Also which program is best for oc'ing nvidia gfx cards? I have tried afterburner in the past and works ok (not too great though).
So please post your GTX580 oc's and give me a few pointers

Cheers from Denmark

Afterburner, as for the overclocking it depends if u are looking for a 24/7 overclock or benching overclocks, i can get around 950 on mine but i need the max voltage the bios will alloe of 1.15v to get that stable and i wouldn't want to run it it thoes voltages 24/7, i would say no higher than 1.1v for 24/7, u get less gains from overclocking the memory but u should be able tu run 2050.

I am not benching much, just trying to get some higher minimum framerates and take advantage of the watercooling. I would feel more at ease with a 24/7 oc.

You should be fine with those clocks.

My old MSi Twin Frozr II 580 OC ran without a hiccup at 950/1990/2150 with 1.125v put through it.

Every card is different do it's hard to say, my old SC had a stock voltage of 1.088v and it ran flawlessly on the stock volts at 850/2050, start at leaving the memory alone and maybe start at 850 on the core and test with stock voltage running something like 3DMark11 and Heaven 3.0, if it runs thoes fine with no artifacts just keep upping the core by 10MHz and keep testing, once it fails(3DMark11 normally driver crashes and with Heaven u can get either driver crashes or visible artifacts) just up the voltage a notch and retest, once u find ur highest stable core overclock on the highest voltage u are prepared to go just leave it on that and try upping the memory 10MHz and nkeep testing, once that fails just back it off 10MHz and then u will have ur highest stable overclock for that voltage, then it's about testing a few games u play and see if it is still stable in thoes games.
