Gigabyte WF3 7950 OCing

Seems perfectly average.  

what does gpuz say your voltage range is? lowest and highest.

for my msi tf3 7950 which is apparently a boost card, gpuz says my voltage range is .808 to 1.220 and i got mine clocked at 1100mhz core and 1500mhz memory.

although afterburner says my voltage range is .950 to 1.250

I have the same card, if you lower the memory to around 1375 I think you can up the clock core to around 1100 as it makes a much bigger difference to performance anyway.
You should be scoring around 9400 on 3D mark with this. You will have to up the voltage a little, let me know if you want me to dig out my settings, im at work atm.
