HD7950: How is this overclock?

post #1 of 8
Thread Starter 
Hey all, I have a Gigglebyte Windforce HD7950.
I managed to get 1150/1450MHz on stock volts...I can probably go a tad higher though. 60C is maintained with the fan speed at 60%. The power limit is at 5%.
What do you guys think?

Pretty good i would say! You could probably go higher, just dont let it pass 85C.

Stock volts meaning....? Cards stock volts range from .9v to 1.25v.

Depending on volts, the core clock may be a bit above average, but the memory is completely average. Looks like you got, which is unfortunate. Seems like a lot of 7950s come with Elpida now.

I highly doubt 1256mV is the stock voltage. So no worries.

max out power control to +20% to avoid any powertune throttling. your card is a boost edition card with 1 ghz boost clocks. so mostly stock volts of 1.25v. you can check core voltage with gpu-z or hwinfo32.

I managed to squeeze a little more out of the card, now running at 1160/1475MHz.
After doing some research and digging, I learnt that the VDDC is the voltage for GPUs...lolz...anyways, at highest clocks it reads 1.15v.

EDIT: never mind, I need to roll back to the clocks in the OP.

Your temps are good. I have had my sapphire 6970 dual fan x2 in crossfire up to 85C running furmark at power limit 20%.
