i'm currently using my old rig (not in sig) with an EVGA 9800 GTX+.
As i'll be getting a new card in about two months (most likely a Gainward GTX 560 Phantom, non-ti), i thought i can play a little bit around with MSI Afterburner...
Which is also my very first attempt on squeezing more out of anything i have than it is shipped with.
i didn't do a lot of comparing (besides MSI Kombustor which raised from ~146 FPS to ~162 FPS), more like "none".
Just played a little bit around with the clock speeds, didn't unlock the voltstuff as i fear i might break something.
what i did was:
Core Clock: from 738 to 785 Mhz
Shader Clock: from ~1836 to 1952 Mhz
Memory Clock: from <1100 Mhz to 1200 Mhz
Cooling seems to be no problem right now (means: not more as it was before... The card gets around 70-80°C, "same" (as i said, didn't compare same speccs with same tasks/benchmarks) as before.
Noob-question now is:
As long as i don't fool around with Voltages, am i safe as long as there're no artefacts and the temps are okay?
And if not, where do i know to stop?
