I have a SLI box crunching with XP, 6.6.23, 182.50, and one GTS250. I dug up an original 8800GT (with a substantial HR03 cooler) and installed it. Both cards are recognised by Windows but BOINC only sees the GTS. What should I do to make BOINC recognise that there are two cards? Or, despite them being both G92s, have I hit a cuda limitation? | |

Ah, solved it myself... I think. | |

No, not solved. :( What does the first couple of lines in your BOINC log have to say? Does it detect both cards or just the GTS250? ____________ BOINC blog | |

Do you still use the 6.6.23? With the 6.6.24 I have the same problem, but with BM 6.6.23 it's running fine. | |

As has been mentioned here in the forum several times - 6.6.2x are BETA versions of BOINC, and have had some problems with GPU scheduling. Suggest you fall back to version 6.5.0 of BOINC client and see if you still have problems. | |

Sadly 6.6.20 is now a recommended version though I think that this was a poor choice ... just as 6.4.5 was rushed out and made the "standard" ... | |

What does the first couple of lines in your BOINC log have to say? Does it detect both cards or just the GTS250? Both cards are recognised by BOINC, it is just really intermittent on using them. The best I can end up with is both cards running SaH and never switching to Grid despite what I set in 'Options', unless they run out of SaH WUs then only one Grid WU runs. *Sigh* I've decided to stop BOINC for a while and come back at 7.0 or 8.0 when things work better. | |

You could easily run a single card, you could try 6.5.0 (which I'm still using as it's so much better than 6.6.x) or you could run seti (if you can justify supporting their science).

Isn't that a bit rush? I've been following the discussion in my other problem thread between you and Paul D. Buck. And it seems it is just going to get worse the more GPU-exclusive time I put into BOINC. I'm not going to run other projects just to make it work. Makes more sense to wait until the problem is fixed. | |

Isn't that a bit rush? If you use 6.5.0 it is NOT a problem. It is only a problem with 6.6.x versions. They made a lot of changes and the problems are not fully resolved, yet. I run 6.6.23 or now 6.6.25 so that I can see these issues on one system but run 6.5.0 on all the others. Please give it a try. | |

I can understand this practice very well, stopped GPU crunching over some weeks by eliminating all unneeded cards from the hosts, using just IGP or low powered PCI cards. Especially GPUgrid regarding the scheduler seems not to be manageable (unattended) by one, single BOINC version in a kind of: configure once > run over months. But I had fun crunching with CPUs also, no more noise, no more overheated computer rooms. It is possible to stay happy without GPU crunching.  | |

Well, currently "fire and forget for months" is asking for too much. Still too much develoment going on at different places: the project, BOINC and the drivers. However, what you ask for is almost what I do with 6.5.0 and my single GPU rig: I keep checking it via "your account", but the machine just runs. The scheduler does what it's supposed to be and does nothing else (well, not that I see anything). Seriously guys, recommending 6.6.20 was a huge mistake by the BOINC developers. But don't let that spoil your fun: if you have issues try 6.5.0! The only drawback of 6.5.0 for me is that it's difficult to keep a small cache to get the early-return bonus. But setting project share and cache size should be able to handle this. MrS ____________ Scanning for our furry friends since Jan 2002 | |
