For all CUDA crunchers. Please, upgrade your video drivers to latest WHQL available and CUDA RT DLLs to CUDA RT 2.3. This could give ~30% (more or less - depending from AR of task) speedup for free ;) |

Ok, url: http://lunatics.kwsn.net/index.php?module=Downloads;sa=dlview;id=208 (though I think "Downloads" section is very known place for all Lunatics adepts ;D ) |

But.. the CUDA_V2.3 file found place in the DL area - after my thread .. ;-D |

Warning - newest NVidia drivers cause problems when crunching GPUGRID wus under Windows XP 32-bit. If your active on that project, don't upgrade right now. |

I'm seeing plenty more than a 30% increase... Currently getting 9.9 credits per minute :) -10.5 minutes per 92.6 credit task -2.5 minutes per 29.08 credit task Which equals 14000 RAC (approx) on a single gtx260 core 216 (highly OC'ed) Which is VERY impressive!

a warning about a experience i had with driver 190.38 on a windows xp computer.. my mother plays pogo games and i had update the driver and it was doing something crazy in-conjunction with java, java was up to date and i rolled the driver back and this problem stopped; so a forewarning on that front... I recommend Secunia PSI: http://secunia.com/vulnerability_scanning/personal/ Go Georgia Tech. |

I'm seeing plenty more than a 30% increase... What are you running your card at for mem/GPU/shader speeds ? What does BOINC estimate your card at in GFLOPS ? I am TCP JESUS...The Carpenter Phenom Jesus....and HAMMERING is what I do best! formerly known as...MC Hammer. |

Yes that's a VERY nice boost, but should I be voried about this Result? Strange is that they are in Completed, waiting for validation state, not invalid ?!¿¡ Who the hell is General Failure and why is he reading my harddisk?¿ |

Estimated @ 117 GFLOPS Core/shader/memory 702/1512/1000 It would be 702/1550/1100 if evga precision was working... Zeus, As long as the result validates it shouldn't be an issue but something is causing memory usage problems.

I run (3) BFG OC MaxCore 216 GTX 260 cards @ Core/shader/memory - 675/1600/1100 ...and a static 75% Fan setting. CUDA device: GeForce GTX 260 (driver version 19038, compute capability 1.3, 896MB, est. 123GFLOPS) CUDA device: GeForce GTX 260 (driver version 19038, compute capability 1.3, 896MB, est. 123GFLOPS) CUDA device: GeForce GTX 260 (driver version 19038, compute capability 1.3, 896MB, est. 123GFLOPS) I am not sure if I am seeing quite the improvements that you are though, although I could be wrong, as I can't see completed tasks to get more info.

looking at your pending tasks your seeing about double the time I am? unless those weren't done as 2.3's? Bob Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957 Or Good Shop? http://www.goodshop.com/?charityid=888957 |

I did the driver update earlier today. I just copied over the 2 x dll files a few minutes ago, then rebooted. Should hopefully see better results soon, as I can finally see results now that the function was re-enabled.

HOLLY CRAP ! .....the 'Pending' are starting to roll in.... 50% +++ increase in performance. 99 sec for a 126 point WU...not too shabby considering I was 200-300 secs previously. I am TCP JESUS...The Carpenter Phenom Jesus....and HAMMERING is what I do best! formerly known as...MC Hammer. |

Thats just the CPU time... Check out the difference in elapsed time (wall clock) It is 1.8x-2x faster :) Bob Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957 Or Good Shop? http://www.goodshop.com/?charityid=888957 |

For all CUDA crunchers. Many thanks, Raistmer! 8800 Ultra - common workunit falls from 14 min to 9 min ;) To keep DCF at 1.0, "flops" had been changed accordingly :) ___________ WBW, Leonid |

Well thanks for the heads-up on that. But having downloaded and unzipped Cuda2.3rt_fft_dlls.7z What do I do with them? Just copy them to the program files\BOINC folder ? PAul [IMG][/IMG] |
