gives me 704Mhash @ 74 deg on one card, 680mh @ 83deg on other.
Actually found out to be false. I got the exact same temperatures.
But I checked gpuz sensors and found out cgminer under-volt does nothing.
How ever I tried msi after burner lastest version undervolting and going down any where near 0.88 just crashes
and ati driver stops responding. I did mange to go from 1174>1156
A read out drop on the sensor from 1.07>1.04 VDDC
And any lower it crashes at 1180 OC
The above numbers are impossible, just fallacy.
I thought it was working too as well, and I realized it wasn't
You aren't going mange a 20% under volt with a 930>1180!
Dream on, getting a 15% higher clock and 20% under volt is everyone's dream.
That simply can't be done.
