    Possible bad 4870M?

    I've been fiddling around with some benchmarking utilities just to see the difference when I replace my current 4870M CFs with the 6990M CFs I'll be getting at the end of the week. I've downloaded and ran HWInfo64 and GPU-Z and ran both of them to capture the peak values of what they monitor. However, I've noticed two different values in both HWInfo and GPU-Z on my 2nd GPU as far as clocks go. I've included a link to a screenshot of my results following a benchmarking session in 3DMark Vantage. I've repasted the cards not too long ago and was certain that the CF cable and cards were seated properly. Also, I don't notice any performance drops when playing games. But how can I have two different values for the clocks? Shouldn't they be closer in values especially under load? There is no overclocking going on and I've installed the latest drivers from ATI. Both GPUs are running the stock vBIOS from Dell. Anyone have any insight?

    Thanks in advance.

    Update:

    Running HWInfo64 and GPU-Z on another computer that runs 2 nVidia cards in SLI shows the clock speed values are exactly the same as far as maxxed values, so I don't think there is an issue with the 2 utilities. Will try to reseat both the cable and cards in the near future as well as run each card individually in either slot.
