Well since i couldnt get any further in the old Thread i decided to start a new one! Have you tried swapping the cards? | |

May be a silly suggestion, but how about checking the speed at which your card is operating? Sounds to me like you are running in 2D or energy saver 2D mode... not 3D with a turbo charger. EVGA precision or something like Everest (or other tools) should be able to give you real time readings on what your card is actually running at. My two cents. | |

The joys of starting a new thread.. he already wrote in the old thread that he's running at turbo clocks. Actually I could imagine this to somehow cause issues. Would be worth a try to switch back to GTX285 stock clocks. | |

Here is a good link to prevent downclocking. My 260 was going to 2D mode until I found this information. | |

Well its not downclocking yet still ive tried that riva tuner thing and it didnt increase the speed on the WUs. | |

If i cant get that to work normally i need to switch with the gtx285 to SETI i just tried a few WUs and they are done in like 3minutes each WU.. This doesn't really help with your problem, but just so that you're comparing useful numbers... The 3 minutes shown on the result web pages is the **CPU** time used, which, of course, is a meaningless number since the application is mostly running on the GPU and not on the CPU. My SETI work units show up as about 3 minutes also, but the actual run-time is about 11 minutes (on a GTX280/Q6600 combination). I know with GPUGRID, the actual run-time is shown in the STDOUT log, and if you're using a recent dev version of BOINC, the manager shows you the elapsed time. Assuming you're not gaming or otherwise running some graphics-intensive program at the time, the elapsed time is probably the most meaningful number. Just to be clear, you said the progress meter was moving slowly. Did the work units actually take much longer to complete too? Although I can't think of any reason why the progress meter would not work well in this situation, I'd want to rule that out and get some other confirmation that the GPU is indeed running too slowly. If it were my machines, here's what I would do in order to diagnose the problem: 1) On both of your machines (Vista/GTX285 and XP/GTX260), finish all BOINC work by: a) Stop all New Work downloads on all projects b) Abort any work units that have not started yet c) Let all in-progress work units either complete, or abort them if you're in a hurry. 2) Set your queue length on both machines to 0.1 days so that only one work unit gets downloaded. 3) Power down both machines and swap the video cards. 4) Power back up, enable new work for CPUGRID, and let each machine download and run one work unit. Disable new work after the work unit is downloaded, and abort any additional workunits that might have been downloaded accidently. 5) Let the single work unit on both computers run to completion (or, if running slowly, at least let it run well past the normal completion tims -- about double the time it is expected to take). 6) After doing this test, if the problem was the video card, the slowness should have moved to the XP computer along with the GTX285. If the slowness stays in the Vista machine, then the problem is with the drivers, OS, or some other hardware or software in the VISTA computer. Also, forgive me for asking a dumb question, but... I assume you're not playing games or running some graphics-intensive program on the Vista/GTX285 computer while running GPUGRID, right? My experience has been that gaming and running GPU/BOINC tasks simultaneously sometimes has almost no effect on the BOINC task, while other times it brings BOINC to a screeching halt.

Well i got a 600watt power supples for the q9300 with the gtx285 and my temperature is at 67°C with gpugrid and 72 with SETI on 40% fanspeed | |

Well i got a 600watt power supples for the q9300 with the gtx285 and my temperature is at 67°C with gpugrid and 72 with SETI on 40% fanspeed Raw wattage isn't the only important characteristic of the power supply, unfortunately. Some (most?) power supplies have multiple rails for the same (12V) voltage. Some have a single rail. If your power supply has multiple rails, you need to be careful to distribute the power among the different rails to spread the load. If you unintentionally put everything on one rail, you may overload that rail, potentially causing problems. If that's the case, the fix could be as simple as hooking up components to different power supply connectors. Other than that, I don't know. 600W should be plenty, unless you have a USB-powered coffee maker. ;-) ____________ Want to find one of the largest known primes? Try PrimeGrid.

It seems to me that his problem is not that the card is too slow, it is that the card is currently unreliable. | |

The other thing that bothers me is -- why is it taking so much CPU time? His slower dual core machine is using half the CPU time to complete a GPU unit.. 32-bit client installed on 64-bit system? | |

switched back to XP to test it and it seems to be as slow as on 64bit vista :( | |

The other thing that bothers me is -- why is it taking so much CPU time? His slower dual core machine is using half the CPU time to complete a GPU unit.. That's because his 285 actually is slow. I checked the tasks: for WUs of similar credit the 285 will take about twice as much elapsed time and have a twice as long time per step. Longer runtime -> more cpu time. EDIT and something else is strange: his temperature is higher under SETI than under GPU-Grid. It should be the other way around.. or has seti recently tuned and upgraded their app? EDIT 2: is the 3D Mark score within expectations? MrS ____________ Scanning for our furry friends since Jan 2002 | |

If it makes you feel better my GTX 295 takes around 7hrs per WU but thats pre-overclock, Hopefully a good overclocking will change things. Plus i get to do 2 at once. | |

5h/WU sounds quite good to me. | |
