Quad SLI Win7 64bit - only seeing 2 GPU's
(Message 13767)
Posted 5261 days ago by far Hi, I'm only seeing 2 GPU's not 4 (when running 2 x GTX295's). It's running the current version of boinc and the lastest nvidia drivers. I've got dummy loads on the 3 video outputs not connected to anything, and Win7 shows 4 monitors active. I don't have SLI enabled. What should I change to use the missing 2 GPU's? Thanks, Far |

Posted 5269 days ago by far Machine keeps crashing/freezing. Saw other thread about GTX260 issues, had thought it was just my card being locked out, but sounds like I'm also an unlucky one. For reference its an inno3d factory OC 216/55nm version. |

Posted 5270 days ago by far OK, it's now running the current WHQL drivers, and I have underclocked the card to about 5% below stock nvidia settings for the GTX260. But it is still refusing to collect tasks. Is there anything that you have to reset on the project side? |

Posted 5270 days ago by far OK I'll update the drivers. Also from memory the card has a very slight factory overclock on it, I'll back that down too and see how it goes. Would be a shame not to get it working since it was only bought for doing GPU calcs! |

Posted 5271 days ago by far Hi, I've got a GTX260 (on machine id 24362 ) that doesn't seem to be doing much. The log has messages like: ---------------------------------------------- 23/11/2009 4:36:27 PM GPUGRID Sending scheduler request: Requested by user. 23/11/2009 4:36:27 PM GPUGRID Requesting new tasks for GPU 23/11/2009 4:36:32 PM GPUGRID Scheduler request completed: got 0 new tasks 23/11/2009 4:36:32 PM GPUGRID Message from server: No work sent 23/11/2009 4:36:32 PM GPUGRID Message from server: (reached daily quota of 5 tasks) ---------------------------------------------- A while back I have a recollection I saw errors with it's returned results. Is this why it's not being given work? Thanks, Far |

Posted 5418 days ago by far Geez this took forever to get the dosh together, the parts to get the australia, and then to get it running! But finally it's stable, and gotta say it looks so neat it's a shame the inside isn't on the outside! The black interior to the case looked so tidy, I couldn't help spending 5 mins spray painting the few things that weren't black to also be black! That's the DVD drive, back panel plus an ice cream container I cut up to help duct the heat out from the GPU's. Shame the fans I replaced with noctua oil/magnetic bearings ones aren't black also. Fingers crossed it finds some protein designs and failing that I'll have fun playing games on it :-) Crunch on!  |

Only seeing 3 GPU's on 2 x GTX295

Posted 5428 days ago by far Checked all the registry stuff till I could understand it, ghosted the drive, then all psyched to regedit (I'm not that techy)... But version 6.6.36 of boinc worked without having to touch anything!! It's running 4 GPU's, all I've done is stuck the 3 dummy VGA loads on that I was using before to trick vista. Phew :-) |

Posted 5429 days ago by far Back from being out of town for a while.. Yes the 295 cores each run at roughly the same as the 295. Early on the 295 would rarely have completed a unit smoothly as I kept pulling the pc apart. From reading around JockMacMad's theory looks like the most likely: Did you try using LimitVideoPresentSources in the registry? Way to go JockMacMad teaching urself cuda to resolve it as I found here: http://boinc.berkeley.edu/dev/forum_thread.php?id=3825 The cc_config thing didn't work for me, so I would like to try the LimitVideoPresentSources registry edit. But first, does anyone know if this method will still allow SLI (for gaming) to be re-enabled? (I'm sure there isn't much advantage to gaming with 2x295's over 1, I just want to know if I have to pull the card out or if SLI will still work with the registry change) Thanks, Far |

Posted 5449 days ago by far All 4 GPU's have the same driver. This machine is a clean (re)build. GPUz confirmed same bios in cards as well. It seems to be mobo related. In the first slot both cards will run as 2 GPU's, but in the second slot they run as 1. Both slots are PCIe2.0x16. Strange. Heard of anything like that before? It's an ASUS rampage Gene with the latest bios. |
