    I was getting around 12000 each PPD with 2 GPUs. Now I'm getting </>50% with 4? The TPFs are just horrible!

    Attached a screen shot of HFM

    Suggestions?

    Could they not be getting the cpu power they need? You have 4 gpus competing for what two had just a few days ago. Try lowering your smp flag on the smp client?

    Fixed it. They were running @ 400mhz while the 1st one was running @ 700mhz stock, guess the OC profile wasn't too nice so they were running in failsafe mode or something? lol

    Reset the clocks back to stock and dropped my volts to 825 and restarted. Now wer're in business :D

    Will mess with overclocking them all stable when I get more time this week.

    It must sound like an airport ramp full of jets in the room where that computer is.
