This math is confusing. Is the 1006 the RAM speed (12% over stock), or what the GPU core actually runs? If it's the core, that's a 35.9% overclock. I thought RAM speed was automatically higher, around 1150 Mhz as stock.
Willi, voltage is not controllable through CCC. Afterburner needs to be installed, and settings need to be changed in it (a tick box to allow voltage adjustment) to change the voltage. Keep in mind this will increase heat output, and if set too high, can damage the card. Try mild overclocks to start with, leaving the voltage alone. After you're comfortable with that, and have found a stable limit, try adjusting the voltage higher, and overclock more. Watch temperatures closely.Edited by UnexplodedCow - 3/14/11 at 8:48am
