    Okay, so today, I commissioned my dad's iMac to folding also. I just (don't laugh, i'm slow okay :p) realized that he runs his iMac 24/7 for no apparent reason, just idling, so might as well use it for some good right.

    His specs are:

    2.4GHz Intel Core 2 Duo T7700 Processor
    6GB DDR2 Ram, 320GB Hard Drive
    256MB ATi Radeon X2600XT Video Card

    and his system, using SMP, got 1% every 15-20 minutes, even at 100% idle. I feel this is strange because on my Air, I'm getting 1% every 15 minutes overnight (when system's literally 100% idle) and 1% every 25 minutes when I'm using the system. Shouldn't my air, specs:

    2.13GHz Intel Core 2 Duo SL9600 Processor
    2GB DDR3 Ram, 128GB SSD
    256MB nVidia 9400M Video Card

    be A LOT slower because of the unclocking done by the firmware to prevent overheating? Technically, my air's running at 1.6GHz with some jumps to 1.86GHz and not truly 2.13GHz at 100% of the time. The iMac however, only hovers around 50-55 deg C for the CPU so its running at 100% 2.4GHz speed, yet its not that much faster than my air?

    Can anyone shed any light on this?

    I have a MBP with:
    2.53ghz C2D 6MB cache
    4GB ram

    I get 31mins for 1%. But i'm running two instances one for each core.

    You should run only one instance of the SMP version. One frame should take 15 mins, close to 2k ppd...

    Your iMac should get the same speed as mentionned in the above post.

    Something is odd about your air, it shouldn't be that fast. The overheating is unfortunatly expected, reducing processor speed...

    Something is odd about my air, its not suppose to be doing 1% that fast, at least I don't think it should. I'll let this WU run through and see if its verified properly or if it throws back errors.

    The iMac isn't going any faster... :(
