6xx overclocking?

[Otis11]

Hey guys, just wondering how high people have clocked on 6xx series cards and still run GPUGrid. Got a beast that needs some ah, serious stability testing... I'm thinking 2 months should do it... but was looking at clocking it up pretty good in the mean time.

Will hopefully crunch after the "testing" but will probably go to more sane clocks.

Thanks guys!

Good to see you, hope school and work are going well for you.

Rock solid stable on all WU types. I think the 670 can do more but it has been running for months like this and I don't want to jinx it.
GTX670 GPU @1249, MEM @3206
GTX650Ti GPU @1270, MEM @3225

Keep in mind that currently the LONG PAOLA WUs are running at very low GPU utilization so these cards will down clock a little (not all the way down to 2d but in the lower 1100s) and may take 12-24 hours on Win7 x64. NATE run nice in the upper 90s%

I bet you can taste that pie already

Oh, I'll be getting pie tomorrow!!!

and it doesn't seem my AC can handle this... before this beast started my AC was running 100% 24/7 and barely able to keep up... since I got those GPUs working, my indoor temp has been rising about 0.5F an hour... Tomorrow it's going to hit 104 here... things might get interesting.

I have tried up to GPU@1215, Mem@3100, it may go a little higher (can bench up to 1255/3555, i think i can crunch at 1225/3450) but i ll test that in the winter. Temps are still a little high. Wish i had 1300+ GTX670

Pushing the MEM to 3450 won't help runtimes much (if at all) and just makes you use more electricity and runs the card hotter!

Thanx for the info. Then i guess i ll just find the max gpu speed and leave mem at stock
