So as it says. what's the best way of making the most of this setup?

I'm Windows 7 with the F@H 7 client thingy. The i7 2600 is clocked at 4500 MHz.

Please don't suggest I should be clever and doing something with virtual machines as I have never got close to working that out, and have even less of a clue how you set anything up in linux.

I've tried all sorts of permutations. The predicted PPD seems to vary quite widely, in an unpredictable way and changes every few hours especially if a WU changes.

  • There was an incredible, but very unlikely 70k using a SMP limited to 6 clients (which when you see the logs says WUs could fail and in fact did) + 1 uniprocessor and the GPU.
  • With the SMP accessing all 8 CPU cores, plus the GPU, it was predicting some 45k, but then a few hours later has dropped to a a feeble 20K.
  • SMP only gets even worse :(

I know different WUs can create different returns but the range of PPD seems silly. I can see something changes with the lower PPD as the CPU temps also drop, currently down from 68 deg C to 62 deg, yet still 100% use. I know GPU needs a bit of a CPU core, but not the whole thing, but is it too harmful to the SMP for even part of the CPU core to be used? Are my PPD predictions even within a range of tolerance or might I have something else wrong :confused:
