Radeon 6850/6870 HD Crossfire overclocking

post #1 of 3

Hey folks, quick question!

I am using the latest Catalyst Control Center to set the overclock on these cards, then test them with FurMark. The 6970 has the option to be overclocked more than the other. Is there any point, or should they both be the same speed?

Is there a better way to accomplish my goal? Im a n00b open to suggestions!

I prefer to use the Heaven Benchmark. It loads the GPUs and has a benchmark score. I like to use the scores to figure out the best over clock. Sometimes I have found that a lower clock than the max I can run, will actually give me a higher score. You can download it here

Also I would keep both cards at the same clock speed.

Thank you for your help!
