Message boards : Number crunching : 570 GTX and 450 GTS GPU %'s

I have the 570 in PCI-e #1 slot and the 450 in #2. The 450 consistently runs the high 80's in gpu usage. The 570 always runs in the low 60's. Is there any way to increase the gpu usage of the 570? I'm using swan_sync and I have 2 cores free. | |

You can user EVGA's Precision software to up the fan speed. Also, you can use MSI's Afterburner to do the same. | |

The 80's and 60's were gpu usage percentages, not temperatures | |

A few people have reported poor GPU utilization on Win7, especially with the larger cards. I'm getting around 84% for long IBUCH tasks on XP. | |

Still getting a good 85% for IBUCH long tasks. | |

I now have 2 - GTX 570's and both continue to have low utilization on all tasks, generally in the mid 60%. | |

I now have 2 - GTX 570's and both continue to have low utilization on all tasks, generally in the mid 60%. Looking at your last successful task on the dual GTX570 rig, it seems your speeds were all over the place. It is down clocking or you are fiddling with speeds. I notice you have 270.61 drivers, maybe go back to the 266.58 driver to see if that cures it. The guys on Seti were also mentioning they have seen down clocking on 270.61 drivers. It won't improve the utilization but might help with the run times. ____________ BOINC blog | |

I'll see how the next 24 hours goes. I did do some overclocking which seemed to speed things up a bit....until both the 570's throttled themselves to approximately 50%...thus the slowdown. The single 570 was stable at the mild overclock, but with both mildly overclocked and a new driver, I have had an occasional throttling problem. | |

The problem with all the recent drivers is that NVidia no longer allows you to stipulate the GPU power management mode from the NVidia Control Panel. I think this is mainly to allow their throttling software to kick in, prevent failures and protect your card. Clearly it's not quite right. | |

Actually, I have the newest Nvidia driver and it still lets me specify "prefer maximum performance," which I have. | |

Prefer maximum performance is selectable only for Win 7 and Vista, which are slower operating systems for GPUGrid crunching. It's not there for XP or 2003 (the faster Windows operating systems for GPUGrid crunching). Some cards throttle down their clocks because of this, while others are not affected. Which cards throttle back could be down to specific manufacturers, models and version numbers. | |
