Your temperatures aren't great, they're very high ;) | |

Before two weeks I didn't had the same problem and I use now just i used back then the same pc. Is this possible? May be something has changed in the working units from the program? I don't know what to tell because I simply can't explain how this is happening... | |

Ok found it! Just had to manipulate fan control. Sorry for the troubles! | |

The 4 temp settings in SmartDoctor works OK, but also depending on room temp. | |

Did you turn off automatic updates? | |

I think that in Windows 7 automatic updates aren't by default on. Sure it can find if there are any available but without your approval it can't install them. the PSU is from Enermax 85+ with 950W. | |

If you are in an area with regular power dips, that could explain the problem. | |

For the power supply I have a surge arrest from APC installed i which the pc is connected to. I have had this sort of problem after installing windows 7 while running for the first time GPUGRID with the drivers from NVIDIA 266.68 but this was solved after installing beta drivers 267.58. The chipset temp is @ 33oC when the pc not stressed with WU and while WU processing @ 45oC. For the two GPUs I have a suspicion; I have found that when I use one of the two no problem is taking place in my pc but when both are running I get to have a restart after a while (the time of period depends). I don't think that anything else is responsible for this just because the last month I had installed Windows 7 about 4 times with the same problem just to check what is the problem. I will try to see also if this happens only when WUs from GPUGRID are processing (that will make me to thing that it's not my pc that is having an issue). | |

Hi, I have 2 mobo's (ASUS P5E), they have probblems with 2 400 series GPU, | |

Now I have set Smart Doctor to auto Fan control and GPU#1 is @ 78oC while GPU#2 is @ 80oC and the fan rotates @ 56%. Chipset temp is @ 46oC. Are these numbers good? I have an 200mm fan in the front of case, a 200mm at the side of the case, a 200mm at the upper floor of the case, a 120mm in the rear and 2x120mm at the side of the two GTX480s. Aren't these enough? | |

Hi, it is quite hot but 80C is a safe operation temp. Lower is always better | |

It seems that it's not only Microsoft's Security Essentials antivirus causing my pc BSD. I have found that "TBPanel service" has something to do with the problem too. I have found that this service has to do with NVIDIA drivers for Gainward GPUs. The one of the two GPUs I have is from Gainward. Anyone has an idea from now on? I had the files "tBPanel.*" deleted from c"\windows\drivers\wow64 (etc.)" directory. | |

An apparent problem with a GPU driver may be a problem with a GPU driver or hardware. | |

I had tested both GPUs alone and found that ASUS GTX-480 restarts my pc after 5 minutes of GPUGRID simulations but GAINWARD GTX-480 doesn't. In both cases the GPUs temps were exactly the same (65oC). For this test I installed latest bet from NVIDIA (270) posted on Internet yesterday. Any suggestions? | |

Try increasing the voltage on the GPU slightly; it might improve stability. | |

In the afternoon I tested the ASUS GTX-480 with the factory drivers (v.197) and tried simulations from another BOINC project (milkyway@home, SETI, etc.) for about 2h and everything were stable. So I connected the GAinward GTX-480 too and installed the first drivers supporting cuda 3.1 in order to run GPUGRID simulations. For the last 1h the pc seems to be working fine and I'll post again tomorrow morning just to let you know if my problem was caused by a faulty driver or I'm still having other problems. | |

Could also be a problem of power distribution, i.e. from which rail does which card draw its power. In that case it might be enough to just swap the cards including all connectors to make the Asus stable and the Gainward unstable. | |

May be this will sound peculiar but I have noticed that when I'm running calculations for SETI with both GPUs, the temps over my GPUs are lower than the ones while running GPUGRID. To be accurate Speedfan indicates that in SETI simulation GPU1 is @ 62oC and GPU2 is @ 60oC and system temp is @ 47oC while in GPUGRID similar temps are 64oC, 65-66oC and 50-51oC. This made me started to thinking if GPUGRID working units are kinda causing my pc to restart with let's say overheating or something. This suggestion is endorsed by the fact that I tested GPUGRID in my pc with under-voltage both GPUs @ 0.925V from default voltage 1.025V and after a while my screen froze and I restarted. For the last test may be it's a driver's issue since I'm using the first driver from NVIDIA supporting CUDA 3.1 (I don't remember the version). | |

UnderVolting would reduce heat, but if/when the tasks require more power the tasks would fail or even freeze your system. In the long term this would damage your system. From 1.025V down to 0.925V is quite a drop (11%). | |

First I would like to underline that there is no problem with the Wus of the GPUGRID since my pc froze with SETI WUs too while testing how both WUs are affecting my GPUs temps. After this small test, I had installed latest drivers from NVIDIA (version 266.58) and tried to see how under voltage is going (still am). Until this morning temps for my GPUs where @ 64oC and @ 59oC while system's temp @ 47oC. Because I don't use CPU for other BOINC projects or crunching anything at all I don't understand why I have an overheating problem. But to be honest yesterday I found out from luck (I used Furmark & MSI Kombustor)that one of my GPUs is by default working @ 1.037V and the other @ 1.025V. And for that reason I would like to see for the next 2-3 days how are things going with both GPUs working @ 0.938V (under voltaged) because I'm starting to suspecting this difference for all the trouble. If no problems occur, then I will start to increase the voltage till both are working to the lower default voltage of one of the two GPUs. Till then, we'll be in touch! | |

I like your tuning idealism. | |
