Will I benefit from bringing in a Q6660 cruncher with a 8800 nvidia? |

I used a Q6600 coupled with a 1 x GTX275/GTS250 & 1 x GTS250 for several years before I upgraded to a GTX460SE on one of my machines with no regrets. ![]() I don't buy computers, I build them!! |

Yes. |

From my understanding it's even better if it's G0 stepping (SLACR). Apparently overclocks especially well. |

They aren't "state of the art" any more, but you might get 4,000 RAC from a Q6600, and a decent amount more from the old CUDA card. So it's certainly on the "worth crunching with" list. Ian |

.... with a 8800 nvidia? I've been trying out an 8800GT. It can do up to 3700/day. |

I run a Q6600 with (2) GTX 460 Just have it feeding the cards (4 tasks) and not crunching. It does about 40,000 RAC all projects.. Mainly on Einstein since SETI is usually out of work. Good machine and heats my apartment in winter! |

.... with a 8800 nvidia? Most likely 10-12K per day with optimized app. |

.... with a 8800 nvidia? Wow. Once I have things in more permanent configurations (the combos/locations), I'll look into that. |

Has anyone got a cheap second hand Q6600 processor for sale? Happy to pay the shipping/postage. |

Used to... gave it to a mate of mine. I do have a i7 920 lying around with a gigabyte motherboard in a box somewhere though. Theres one going on ebay uk at the min for £35 or so with 27mins left on the auction :) |

I run a Q6600 with (2) GTX 460 +1 I got Q6600 with one GTX 460 2GB. Run 3 cpu tasks, 1 gpu task, then when I go to bed I switch to 8 gpu tasks. ![]() |

My everyday hack Q6600 (SLACR @ a mild 3GHz) runs dual GTX550 Ti's crunching on all cores plus 2 per card got up to a RAC of 32,000 (and climbing) when the limits and troubles hit so now it seems that every time it gets back up to 25,000 a backup project or two has to fill in for the lack of work here. Cheers. |

I have a Q6600, G0 stepping, running at 3.2GHz (has been since I got it years ago) with 2 x GTX470s. Runs WUs on all cores and 1 WU per GPU. With this config, it had a tendency to runs at a RAC of circa 45k (when we had caches, seems like a distant memory now). It was running with a RAC of 34k and climbing at a rate of 1k per day before it ran out of work. It will run quite happily at 3.4Ghz on air, but can be a bit flaky on a hot day though. cheers |

Check out my system , and results. Running Q6600 and 560 ti ( super overclocked ) Though ignore the 560 ti atm as it is playing up and keeps dropping to safe mode ( 405 ) and I have done all i read to solve it. Will be upgrading to a i7 cpu ( and new MB / ram ) when I can afford it :/ ![]() ![]() |

It's a sort of "tangible" reminder of what this is about; an actual signal out there somewhere that could end up being heard by the Arecibo dish, recorded on the tapes, processed through the splitters and sent out through Berkeley's clogged bandwidth toward becoming the greatest astronomical discovery in history having a profound effect the outlook of Humankind. Wow :) |
