overclocking 7970

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.
 
Do HIS have there own overclocking Tool???

The manufacturer of the cards own software is usually the best place to go as its the Bios on the cards that determines the stopping place of the sliders. My AFterburner has almost no limits at all.

You can also try GPU tweak by ASUS and enable the higher overclocking ranges.
 
HIS have their own overclocking tool.... HIS Turbo. Extremely easy to use.... I installed my new HIS IceQ 7970 GHz card this afternoon, ran HIS Turbo, clicked the sliders up and had it running apparently stable at 1250 / 1550 at stock volts in 10 mins (although it allows you to up the voltage), been happily playing and benching with those settings without a crash since. :cool:

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 :)

Sleeping dogs extreme preset has weeded out many a unstable overclock for me that unigine/furmark/kombuster have not picked up.

If its stable on sleeping dogs extreme preset, its stable on anything.

Just play the campaign and drive around a lot for 30 minutes.

Pretty much several loops of Heaven and also pick a game that whoops the GPU's butt and play it over and over or use it's benchmark loop if it has one.
 
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)
 
Are you using the Metro 2033 test? You can loop that afew times and set it all to max, its in the steam folder with the game i think, maybe in the steamapps folder..
 
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

7970's are built to operate in the mid to low 80's. As long as you're below 90c, you won't have any problems, same for the vrms. :)

Once overclocked though its best to keep temps at 80c or below.
 
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.

Mine can sit on 1100 on the core with volts of 1112mv. But not matter what volts I add, Anything past 1175mhz, it artifacts in heaven, Tiny little white pixels popping in the textures. I don't really have an issue with temps, They stay around the same 70-75ish with a reference cooler on the XFX black edition. I was looking at more cooling for it, but if i cant get it to go any higher, Is there any point?


Your clocks are looking very nice, I'm not Jealous much :)
