just built a 8 core Harpertown, currently at 3405mhz and shooting for 3870mhz with a volt mod and a BSEL mod.
----------------------------------------Machine after one day is claiming at a rate of 36,238 a day and claims vs award are almost identical. Machine is a SM X7DWA-N MB, 2-E5450 Harpertowns and 4x1 gig Kingston HyperX DDR2-800FBDimms. A beast for computational power and is eating up the HCC WU 8 at a time at app 3.2-3.3 hours each.  |

The beast is impressive but the time per HCC WU is not. Which system are you running?
----------------------------------------Based on the average 3.0 hours that they need in my Q6600 at 2.88 GHz under Ubuntu 64-bit I would expect yours to need only 2.5 hours. Strange. Cheers. Jean. |

On an individual basis the dual sockets will never be able to match singles but in terms of pure power they dominate. Also comparing windows and Linux is tough. Linux is much more efficient IMO I just talked with the guys at Xs and compared to windows machines with Q6600's,and Yorkfield 9650's and the times make sense. |

OK, thanks. As you can see I am very ignorant about the Xeon world.
---------------------------------------- It's sure that the number of WUs per hour out of your box is still much more than from mine. Cheers. Jean |

Jean The dual socket boards are more like Clydesdales vs the gaming boards being like thoroughbreds. Limitations with memory, IE: The 800FBDimms will max out depending on brand between 420-450 That makes for a maximum FSB speed of 1800 possible. I'm at 378 now until I BSEL and volt mod so thats a small factor. Your 3.0 hour time at 2.88ghz is excellent for that speed. I was hearing 3 hours for machines clocked in the 3400-3600 range so you have a winner there! [Edit 1 times, last edit by Movieman at Jun 30, 2008 12:07:31 PM] |

HCC feels very happy under Ubuntu 64-bit. It does not make such a big difference for other projects. I think it might be because it does more integer computation than the other projects. When looking at the benchmarks the floating point values are the same in XP 32-bit and Linux 64-bit (about 2800). But for the integer value I get something like 5800 for XP 32-bit and close to 8100 for Linux 64-bit. That makes a difference.
----------------------------------------My (uneducated) guess is that the Q6600 might take advantage of the 64-bit width to handle twice more integer data at once whenever it is possible. But I might be completely wrong as well... Cheers. Jean. |

Jean. When I ran the WCG bench I got 3456/10097 under winXP64 maybe I need to expand my horizons and try a Linux install..Thats if these old brain cells can figure it out..  |

If my old brain could do it why not yours?
---------------------------------------- However from the figures you give it seems that XP64 is already offering you the "integer effect" I was mentioning. Cheers. Jean. |

AFTER 2 days up with both cpu's at 3404 it looks like it's doing app 34,000 points a day. I want 3870mhz from this and interested to see what effect the increased buss speed will have. From there I might try Linux just to see what effect there is. Thanks again for the imput.. |
