ATI 6970s Average Overclock

Hey dudes,

I was jus wondering whats a good clock speed for these cards, I currently have them at: core 890MHZ, and mem clock at 1390mhz clock. However the increase in performance is almost unnoticeable. Heres the link to the cards I have

What clocks do you guys think I can reach with the 6970s I have, I want to increase my benchmark performance considerably. Ive seen people with my exact same setup scoring close to 10k on 3dmark 11. However! I cant see their GPU Clocks due the forsaken "driver no supported" mesage. KK thanks :D

10mhz. You really thought you'd get a good increase from 10mhz?

So far, the highest OC I've seen in reviews is 950mhz in the core. Increase the core by 10mhz increments, and run a 3DMark11 bench. If it freezes, back it down by 5mhz increments until it's stable, and then run a 10min OCCT GPU test at optimal shader settings. That's the method I use currently, and it hasn't failed me yet.

LMAO I haven't tried anything above 10mhz due to benchmark crashes, however 3dmark 11 isn't that stable compared to vantage or 06 in my experience. Regarding the 10mhz increase should I do the same for mem clock? What kinds of clocks have you seen for memory clocks btw? robertoenrique

Wow, really? You're hitting instability at those clocks already? Hm :?

Are you sure your CPU OC is fully stable? Because I know my friend had overclocking woes with his GPU's as well, only to find out it was his processor that was unstable.

Just hit a wall on mem clock at 1420mhz, 3d mark 11 crashed. I'll keep un bumping core clock. Benchmark runs perfectly now after I removed CPU overclock, so yes it wasnt stable. robertoenrique

Lol well there you go. Glad to hear you managed to find your problem.

But yeah, just keep on bumping it up by 10mhz until something weird happens with 3dmark11.

try changing your voltagesgrackfields

6970's don't have automatic voltage tuning capabilities.

Another wall :( Core at 930mhz causes my Pc to freeze. Oh well looks like Im gona have to do with Core at 920Mhz and Mem Clock at 1410 Mhz. I'll Oc again my CPU now. Score should be around 8500 marks now. I'll post back. Thanks for the help dude. robertoenrique

a 6950 1gb at 950 mhz core will match/beat a gtx 580, so a 6970 at 920mhz should do the same if not better

Here's a benchmark to try to compare to if you wish to beat two 580's :)

Hey raven whats your 3dMark 11 score btw?

This is 3dmark 11 of an oc'd 6950, you can see that the oc'd 6950 gets a score similar to a 580 gtx. Also 2 6970's at stock should have a 3d mark 11 of 10000

EDIT: Image doesnt seem to be working so i'll post the link http://techgage.com/article/amd_hd_6950_1gb_vs_nvidia_gtx_560_ti_overclocking/8

Hey raven whats your 3dMark 11 score btw?

P7910 :( My processor's severely pulling down my score as it's only clocked at 3.6ghz.

I maxed CCC options for my XFX HD6970 (950MHz/1450MHz) off stock cooling and voltage.
