Stock GTX 670...

Anyone with experience with OC on these, I'm looking to get as much as I can out of it, within safe perimeters ofc.

I am a highly experienced overclocker, but sadly i am still on Fermi hardware, although i am upgrading to GK110 (new build).

OC'ing Kepler has a lot to do with temperature, as the card will throttle if it can not run cool enough, this will limit your OC before anything else.

I recommend trying to keep 75-80c as your maximum temperature under heavy gaming.

As far as voltages, i think only few cards have unlocked control for this, or you can flash a custom bios yourself, which also brings on a host of issues if you mess that up, including a bricked GPU.

It will throttle at 70C, and then again once it reaches 80C. Default fan speed for my GTX 670 Sig2 is 30%. For certain games that are more GPU-hungry, I manually increase the fan speed to about 50% and that keeps my card under 70C.

Keep in mind, i'm using GTX 670 Signature 2.  It has a better cooler than reference models.
