So, I tested what overclock I can run with my card still stable. I got to +120Mhz core clock and 7.800Mhz memory clock.
I tried three settings for the voltage control. +0mV +20mV and +40mV
Strange thing was, that the +120Mhz core clock resulted in different max CPU clocks depending on the voltage -> 1486Mhz (+0mV), 1499Mhz (+20mV), 1512Mhz (+40mV)
Benchmarking results with Heaven:
+0mV: Score 1883 / 74,8 FPS
+20mV: Score 1880 / 74,6 FPS
+40mV: Score 1895 / 75,2 FPS
Strange that the second is lower than the first.
Also, the power consumption obviously varied. It was hard to say exactly by how much thought. TDP was around 80-85% (0mV), 85-90% (+20mV), 90-95% (40mV).
Attached you can also see 3 screen shots of the testing.
So, how should I set up my card? My aim is to get a little bit extra out of my card. I am not a hard core gamer and am happy if my card can last 1 year longer with an overclock. But I do not want to just waste power because I crank up the card to the absolute maximum just to get a few FPS extra out of the system.
I guess the question is, where is the sweet spot between power consumption and added performance. I read somewhere that the most gain is around 1400-1450Mhz. Everything above that cost a lot of power to achieve. Is that correct?
