So i'm trying to overclock my Asus GTX 560 Ti. The first overclock i got was 950 Mhz (stock is 830 mhz) without even changing the voltage. Now i wanna try and push it to 1Ghz. I've done that, and everything runs just fine, except Furmark, which gives me a driver error after 6-7 minutes.
Here are my settings:

With the built in limit, you can push the voltage slider to the max without damaging the videocard. The bios has a software limit that prevents you from using higher voltages than the company wants you to use, and a common mod for these cards, is modding the bios to allow for a higher voltage.
eg on my gtx 460 (I don't mod the bios until I have had the card for a few months (since modding can void your warranty if the card fails in a way where you cant restore the stock bios)
Also when testing your card, you need to use a program that can run the GPU at 100% continuously and see if it artifacts or crashes after 30 minutes.
With a 100% nonstop GPU load, the GPU will get hotter than normal so hitting 90-93C is acceptable, if you hit 95C then either find better cooling or lower the voltages and the overclock. The GPU's can generally handle up to 105C before overheating but it is not good to run them near their upper limit unless your card has a life time warranty and you are okay with paying for shipping to RMA it eventually.
PS also look into overclocking the RAM, if offers a tiny bit of improvement
I plan to eventually increase the voltage further and overclock to 930MHz
