A question for the devs: Is there a cuda 3.2 app in the works? The CUDA 3.2 toolkit is still at 'release candidate' stage, according to http://developer.nvidia.com/object/cuda_archive.html. | |

Hi, | |

I've updated drivers to 260.89 at present, just waiting on the DLL's and apps to become available to use it. Older cuda apps seem to be fine on it. Presumably there will be some speed improvement for Fermi-based cards when using cuda 3.2. | |

Similarly, I've been running 260.89 drivers for a while, in three combinations: WinXP/Fermi, WinXP/9800GT, Win7/9800GTX+. No problems, and if anything GPUGrid has been running more reliably on the 9800GT-series since the upgrade - though that may just the the variability of the tasks issued (I still can't get the HIVPR_n1 series to run on the older cards). | |

I have been using it since it was in Beta, without too much trouble. By itself it brought no speed increase over the previous final release on a GTX470 XP x86. The dll files in 3.2 might help, but only for some tasks; for those already at 93% to 98% GPU utilization there is little improvement to be had. | |

Similarly, I've been running 260.89 drivers for a while, Has anyone noticed a slowdown (lower GPU usage) with v260.89? Is there a way to force the driver to use max power instead of adaptive mode? The max power option seems to have disappeared from the preferences. | |

Yes, but I think it is the lightweight IBUCH tasks rather than the driver. | |

Yes, but I think it is the lightweight IBUCH tasks rather than the driver. I did not say less GPU utilization, I said SLOWER. After more fiddling it turns out that with 260.89 the GPU runs at the correct speed after rebooting for about 1/2 hour, then drops to about 55% shader and core speed. The only way I can get it to go back to full speed is to reboot WinXP-64. Anyone have a solution or just go back to the 258.xx drivers? I can't find a way to turn off the adaptive power setting... | |

Beyond: set the windows power settings to maximum performance?

They could still optimize routines and avoid some unneccessary calculations here and there. Not saying this is possible with the current code, just that generally even at 100% load there may still be room for avoiding calculations ;) MrS ____________ Scanning for our furry friends since Jan 2002 | |

Thought you would pick up on that ;) | |

Beyond: set the windows power settings to maximum performance? Yep, always. Last night installed the new v260.99 on 2 machines with GT 240 cards. One seems to be staying at high power while the other one is dropping to low power even faster. Once they drop to low power it seems that NOTHING will bring them back short of rebooting. | |

For driver 260.99 the Power Management Preferences are now under the Program Settings Tab, however I was not able to set Power management preferences to Maximum; there is only the one setting, Adaptive. So avoid this Beta as well (NVidia Control Panel version 3.4.772.04). | |

Thought you would pick up on that ;) It was an unfortunate coincidence that these frequency reductions occurred during the release of many lightweight tasks. I came across cards reducing their frequencies before (as did many) and found that by using EVGA Precision and leaving it open on the desktop my cards did not slow down, but that workaround may not work on this occasion. Good suggestion. I tried installing the NVidia Control Panel and NView from v258.96 (over v260.99). Still no power settings and still went to low power about 30 minutes after rebooting. Tried leaving MSI Afterburner and a host of other programs open to see if they would stop the down-clocking but no go. Actually v260.99 is also listed as WHQL and seems to have the same problem. I reverted to v258.96 and the problem is gone. Kind of looks like the NVidia driver team is trying to match the success of their chip designers... ;) | |

At least the fans didn’t stop this time :) | |

To see two broken WHQL released only a week apart tells me something is wrong there. Could be by design. Thinking "so many people are wasting electricity by choosing high performance for no reason, so let's just make adaptive the standard" and setting the load detection wrong, so that compute doesn't wake the GPU up properly. This would be the real bug - for a company pushing GP-GPU so hard one would expect a little more understanding for the needs of the people actually buying their GPUs for crunching. And give us the Tesla drivers for desktop GPUs please, so we can manage our headless crunchers via remote desktop! MrS ____________ Scanning for our furry friends since Jan 2002 | |

Just an update. Eventually all 3 machines on which I installed v260.89 & later v260.99 reverted to GPU low power mode when running GPUGRID with no way to return to normal speed except rebooting. After rebooting low power mode would return after ~ 30 minutes. All machines were XP-64 and all returned to preferred normal (remaining in max power mode) behavior by reverting to NVidia driver v258.96. | |

low power mode when running GPUGRID with no way to return to normal speed except rebooting. What if you launch a game? Does it speed up and stay there for another 30 mins? Sorry if this has been answered before, I haven't paid much attention lately. MrS ____________ Scanning for our furry friends since Jan 2002 | |

low power mode when running GPUGRID with no way to return to normal speed except rebooting. I don't game so can't tell you. I did try loading MANY misc apps and GPU monitoring programs to see if he GPU could be coaxed back to a higher speed, with no success at all. Only a reboot seemed to do it and then only for a short time. A REALLY bad bug IMO. | |

A REALLY bad bug IMO. What has the feedback on the NVidia forums been like? | |

Anyone who's still got them installed try lauching a 3DMark or Furmark. That should surely trigger 3D mode. But don't use 3D Mark 2001.. that's been cpu limited since many years :p | |

I just wish I could do more than one gpugrid wu, I kept on downloading and downloading wu's for gpugrid and they'd all error(Computation error 3) out on this 6.13 cuda31 app on My GTX295 v2(6 in a row one after the other), Yet I'm not having problems with wu's on My GTX295 that are from Milkyway@Home or from Seti@Home in the recent past(S@H is down for a few weeks while 2 New HP Servers are configured and tested, The forums should be up, Just not until morning at the moment) as their both using cuda23, Which works here on XP x64, My video driver is 257.15 and Boinc is 6.10.56 which I like better than 6.10.58. | |

This seems some configuration problem. | |

This seems some configuration problem. I know why, From what I've read this project does not support My favorite video driver 257.15 which works really well with the Lunatics X32F 3.0 cuda Seti app which does not support any driver earlier than 256. Reinstalling Boinc in a different folder is a lame idea to Me and would not produce results and I'd have to reinstall My Seti apps and such, So don't ask to Me to do something so stupid again. ____________ | |

I'm not trying to be a wise-guy but seriously, if you are so upset why not just leave? | |

BTW, do you plan to release a cuda 3.2 application in the near future? | |

No, not before end of January 2011. | |
