I got a Gigabyte OC 560 ti (900mhz core, 2000mhz memory) and it was running very cool (it has a double fan cooler), so I decided to push it a bit more.
Since this is my first try overclocking a gpu, I'd like to know if this seems safe: 1ghz core, 2165mhz memory at 1.062v, running at 58ºC at full load.

I got to 922 and 2094 with 1.025v (what was default for this card it seems), but when i tried increasing core I'd get driver crashes, so I messed a bit with the voltage and was able to increase core and mem a bit more without crashes. I'm just wondering if 1.062v sounds like a bit too much for the overclock I got, or if it is around the expected.
