3. In regards to above, if I mess with the voltage, will that affect my CPU overclock too? I OC'd my CPU earlier and I'm worried if I have to increase voltage that that will somehow affect my OC for my GPUs.
4. Is EVGA Precision the best way to OC the GPUs?
5. What kind of performance gains would I be seeing?
6. How do I know if it's stable or not? Artifacting, shutting down, etc.?
1. Start by adding 50mhz to the clocks with no voltage increase. After that move in 15-25mhz increments.
2. For GPUs you don't need to go into the bios, use EVGA's software or MSI afterburner to control the voltage and clocks.
3. It will not change your CPU overclock.
4. EVGA Precision or MSI afterburner, I pref afterburner.
5. Download Heaven HERE
and watch it as it runs, when the program is open, there is a button to click that says "benchmark", this will track your progress in performance, and you should watch the runs for artifacts or if the device driver fails, restart and go down in mhz or up in voltage.
ALSO, make a custom fan profile for your cards so they aren't getting too hot. I would reccommend putting them at a minimum speed that you can't hear them, then scaling up ~70c to max fan speed at ~80-85c.
