  • SLI no better than one?

    I got 2 GeForce 460 SE, installed them SLI and ran 2 benchmarks:
    Futuremark and Passmark. I can't see how SLI has helped. Both cards appear as expected in EVGA Precision, but the GPUs remain cool and I don't know if SLI is active. How can I test my setup? I'd really like to know that I didn't waste a bunch of money. Thanks for any suggestions. Mike.

    See these old threads.

    But even though we didn't see any significant speed increase with SLI, we could force the benchmark to run on both cards via the device driver. So check the device driver control panel to see if SLI is on.

      sli is better than one!

      Thanks Passmark.
      Once I'd switched on SLI in the device driver, as you suggested, my score went from 13011 to 18024, about 40% improvement. I just wanted to make sure the second card wasn't dead!
