6950: Max stable OC on stock volts

post #1 of 5
Thread Starter 
So far I'm getting it to stick at 950 core 1450 mem (65 degrees at load)... only have a few
issues every few hours in crysis 2 ;p

what is the point of increasing volts,
and why would you over volt? I can't find anything really
informative on the interwebz, and I'm trying to max my performance
on my 6950 (Sapphire)

Issues every few hours means you're clearly not stable. You increase voltage in order to increase stability at higher clocks. There are stress tests like furmark out there, but its better to just test stability with the games you regularly play. If you get crashes or artifacts, raise the voltage on the gpu a bit and try again.

increasing volts would increase the chance of powerplay kicking in right?

My Sapphire crashes at 900/1400, while around 60 C temps on stock voltage. It runs at 880/1375 (6970 speeds) well, but every once and a while has a flicker in Heaven 2.5. Kinda crazy that some people can get high clocks on stock voltage and mine will barely go over 6970 speeds without freezing.

It's probably my terrible power supply. Need to get a nice one ASAP.

940 bench stable @ 1.1v but only 920 game stable. Gaming causes more voltage fluctuation due to varied load, which is a better indicator of stability.
