hey how you goin, i've been having troubles with a Gigabyte 7950oc stock at 900/1250 at 1.090V,
after some testing using furmark/gpuz & gpushark, hwmonitor and 3dmark11 and BF3. I found that at stock clocks using catalyst drivers, overdrive and power @ 20% it was actually around .890v. I got it up to .900 with it on 0%. Not sure what was happening there.
I was having issues with BF3 @stock settings, but could run 3dmark,but any overclock would result in every different error from 3d mark 11. If i did any o/c the voltage still stayed below 900mv. Once i finally relised even at stock clocks i was nowhere near normal volts. I moved on to Afterburner, manually set it to 1000/1350 @1100mv,which is still only bringing it to 1049mv/1061 peak on Gpu-z and 1090 in hwmonitor.
Im stable now, i can play bf3 stable at 60 degrees, Furmark is stable at 71 degrees. I just think they have poor voltage regulation. Set the voltages manually for piece of mind. But i still haven't got any control of the power setting on either msi or catalyst. I have checked and seen no changes and vddc or mem voltage and noticed no change at tdw. I think i got a dud in that department.
Learnt something new i guess.
