I know its not really worth it, but at least I wanted to try it. Running GPUGrid ona GeForce 8200 OnBoard Chip...
Did I miss something? I exptected that it will work - not fast enough, but still... (??) Installed NVidia 178.24, BOINC 6.3.19 I couldnt find the info if 8200 is CUDA 2.0 capable Any advice is appreciated! Cheers! |

Your error seems to be: Cuda error in file 'deviceQuery.cu' in line 59 : out of memory. Read more on this here: http://www.gpugrid.net/forum_thread.php?id=340 |

try vista or server 2008 (or win7 is you can get ahold of it) and see if the problem is still there. Im just curious. |

Thanx for the input. During the night, my computer froze. Since the only change since yesterday was to install Beta BOINC Client 6.3.19, I have no other idea what could have caused it... I downgraded to 6.2.19 again and will see if it happens again... But thanx for your comments. Good to know that it should be possible, at least in theory on my host! :D try vista or server 2008 (or win7 is you can get ahold of it) and see if the problem is still there. Im just curious. I have none of these OSs... :( Sorry, can't satisfy your curiosity! |

you can download server 2008 form MS's site here: http://www.microsoft.com/downloads/details.aspx?FamilyId=B6E99D4C-A40E-4FD2-A0F7-32212B520F50&displaylang=en (at the bottom of the page) |

"Out of memory" .. the onboard GPUs usually don't have local memory and have to used the much slower system memory. It may be that GPU-Grid expects local memory, because crunching in the system mem is totally out of the question, performance wise. In that case you could fiddle with drivers and OS as long as you want, it won't help ;) MrS Scanning for our furry friends since Jan 2002 |

I think that you are on the right track here, but I doubt it is the memory performance giving an "out of memory" error. Rather, since on-board GPUs frequently default to an "on-demand" memory allocation request of portions of system RAM, my guess would be that BOINC or the GPU app. doesn't like the way this request is handled. The original poster might check and see if a fixed allocation can be set to mimic a discrete card and memory. |

With older GPU-Grid clients if you were playing some relatively new game, GPU-Grid finished a WU in the background and BOINC tried to start up the next one, you'd get this "out of memory" error. Riva Tuner tells me that GPU-Grid uses less than 80 MB on the GPU, which shouldn't be a problem for 512 MB cards (also happened on GT200 cards with much more memory). So what does this mean? The GPU could easily use system memory, if it runs out of local mem, so why this error? System memory is not full yet, the games are not that greedy. But historically they have been using one CPU core completely, irrespective of performance needs. I guess they're doing the same with local GPU memory, reserving space prior to actually needing it. In the past this would have been totally fine. If I'm right with that, then I can explain the rest: the GPU-Grid app can distinguish between local and non-local memory, so it crashes when greedy games are running, despite the fact that there is still system memory available. And that means that the app also crashes with onboard GPUs, as they don't have local mem, regardless of what portion of system mem you tell them to use. Would be interesting to try though, any allocation >=128 MB *should* work. (on a side note: I don't want to imply that this behaviour with GPU-Grid and games has changed in recent client versions, I just don't know) MrS Scanning for our furry friends since Jan 2002 |
