I would use the guide I posted, no matter if you are changing your voltages or not. There's a reason it's been sticky'd.

I wouldn't heavily rely on other peoples clocks, each chip has its own limitations. Overclocking is a process of trial and error.

The memory clock is the one you have to watch out for. 950+ is pretty easy on the GPU clock, but I wouldn't go above 1350-1400 max memory clock as that's the one that will limit your OC. I use to run mine @950 1350 24/7 with no heat problems. Those 5770s run VERY cool at very low voltages. This 5870 runs a little hotter, but still cool compared to the old 90nm GPUs of the past.

Going from 925 to 950 wont merit a noticeable difference, just like going from a 1385 clock to a 1400 clock.

My XFX Juniper XT's in CrossfireX ran a 925/1385, temps maxed at high 70's.
925/1385 is a nice improvement over 850/1200 and its easily obtainable without touching the voltage.

i ran my at 1000mhz on the core?
post #17 of 19
When I was running one card, I usually had it clocked at 1050/1400 at 1.30v or 1000/1400 at 1.25v.

Stock voltage I can get up to 980/1400.

Temps never go above 65c.

With both cards installed, I run them at 960/1350 stock voltage. Still never goes over 65c

This except I'm at 1000/1500 @ 1.25v <66C
