    While i have just recently destroyed my 8800gt leaving me with just a nvid 250, i have been trying to limit my ppd drop by using the smp on my q6600(using the fah gpu tracker... Its far more usable than the old DOS client thing i turned away from).
    Hoping to get the best speed/performance on these smp work units i am trying to o/c my cpu.
    So far i have got up to 3.42. From 3.1 i have not noticed much of a performance increase on the smp. Is there any point trying to push the chip to 3.6?
    Any help welcome.
    Thanks,
    Loons :rock:

    I don't believe you will see any viable performance bump. Maybe few extra PPD and that's all. LGA 775 chips become very power hungry when you push them to the limits so you're going to end up wasting a lots of energy. Don't mean to rain on your parade, but I believe it's not worth it. Keep it as it is and your chip will live longer too.

    I have 3 Q6600s Folding, currently they are Folding P6067, two are at standard clocks (2400MHz) and the other is at 3600MHz. The two standard ones are serving 2xGTS450 and 1x8800GTX they are getting 3179PPD and 3908PPD. The Fermi (OpenMMGPU3) client is well known for taking more CPU time than the GPU2 client. But the 3600MHz Q6600 is making 6347PPD whilst serving 2x9600GSOs, so yes over-clocking does increase your PPD.

    P.S. The 3600MHz Q6600 is under Phase so is running in the negative degC

    Why not save up and get a gts430 or gtx460. One of those will give more points than both your current cards could. (especially now your 8800gt is dead)

    thanks for the help.
    I think i discovered my problem,.,., prime caught one of my cores failing almost immediately @ 3.41 even when it the system was stable for an entire evening. I have currently reverted back to 3.1 until i have more time to fiddle with the volts to see if i can get my 3rd core stable at a higher clock.
    Now that my 8800gt was killed by trying to get the heatsink off to add a new cooler.... and pulled off half the card with it.... i have persauded the Better Half that a nvid 460 would be an ideal Xmas pressy. Smp until then to try and keep the side up. Roll on Santa. :brrr:
    Thanks,
    Loons :jawdrop:
