overclocking 7970

[JimInk]

Hi guys, i have been playing around with overclocking my HIS x-edition 7970 using msi afterburner.

Its been going well and is stable at 1200mhz core and 1600 mhz memory. However afterburner has a maximum memory clock of 1600 and i have seen other people clock beyond that. So is there a setting i have obliviously failed to find on afterburner, or is another program used for pushing it further?

Thanks in advance.

Thanks for the help guys, I'll try out the HIS tool first

I'll report back with how it goes.

Hurrah! Getting it past that 1600mhz limit now.

Currently stable on 1200/1700 and doing stability testing. What are the best gpu stability testing program's? I'm using msi kombuster and heaven 3.0 to check its ok.

Thanks

Thanks again for more help, the community here is awesome

@LtMatt i dont have Sleeping Dogs, Metro 2033 good for pushing the gpu?, seems to be intensive on it.(will prob pick up sleeping dogs though and dishonoured as they both look fun)

I've upped my volts a little, everything I have read says that temps are more the problem, but I'm keeping the volts below 1200mV no matter what as I really like the card and don't want to risk it. Currently keeping temps at 60degrees ish which is fine with me

Is going well with the clocking

It's at 1210/1675 with core temps maxing at 60 degrees, seems stable on heaven, getting 2209, and fine on metro test too.

Vrm temps are hitting 74 degrees on vrm temp 1, and 64 vrm temp 2 (on gpu-z sensors, not sure if that is a good sensor to use). Seems high but within reasonable limits. Might clock it down for normal usage though.

Just updated to the 12.11 beta driver and that increased the heaven score by a hundred 0_0 and I dropped the voltage a notch. I hope it is a pretty stable driver as it seems to be very good...

Gonna keep testing and try some more game tests to see how it runs for me.

Yeah, that's the one with the blue pcb.

Currently dropped the memory back to 1600mhz as I would occasionally have graphics glitches during games and that seems to have sorted it out. Core Clock at 1250mhz and gaming/benching very well. Have had to put the core voltage to 1200 get that but the temps still sitting at 60 with a slightly more aggressive fan profile.

I suspect a little more juice to the memory I could clock it up but doesn't seem worth it cos I don't want to risk anything.
