Graphics cards (GPUs) :
GTX 280 has a compute capability of 1.0?
(Message 17813)
Posted 5044 days ago by CodeRedDewd haha! my cpu is slow... It's OC'd from 2.6 to 3.15. It does pretty well. Something I cannot figure out is... What are the main factors to consider when looking for a great card for crunching numbers? If you compare the 9800gx2 to the GTX 295 co-op for example. The gx2 has a higher gpu clock (600vs576), higher shader clock (1500vs1242), equal memory clocks. The gtx 295 has more memory interface (448bit/gpu vs 256bit/gpu), more processor cores (480vs256), more memory bandwidth (224 GB/s vs 128), more texture filling units (160 vs 128) The 295 is slower, but seems to have more stuff doing the work. It seems I've seen some who had a lower RAC than me with their 295 wehn I had my 9800gx2, unless they didn't have the co-op edition...I just realized that. So what's the conclusion? I'm just fooling around and don't know whether to get a 295 co-op, or another 280 to pair with what I have.... |

Posted 5047 days ago by CodeRedDewd Curious question then... What did it mean when it said (... + 1.1 NVIDIA GPUs) if 1.00 is 100% That's what it did say with my 9800gx2 I have a handy sidebar gadget that shows the gpu temp, pcb temp, VPU and GPU usage, ram, speed... all of the graphics card. http://blog.orbmu2k.de/ The one I'm using is GPU Observer. My GPU never goes much over 70% I'll look to see if I can find the stderr_txt file... |

Posted 5047 days ago by CodeRedDewd So the 9800gx2 was a 1.1 card, and it showed as such in the "status" column. So theoretically it should be showing as 1.30 and not 1.00, but just be wrong? Let's say that it's showing wrong. Does that mean it is computing the way it's suppose to be? What would be the effect of running a 1.3 card at 1.0? That's all I'm wondering. |

Posted 5048 days ago by CodeRedDewd It shows it in the Status... (0.33 CPUs + 1.00 NVIDIA GPUs) with my 9800gx2 it showed 1.1 where it now has 1.00. Is this not where it shows how it's computing? I understand line 13, just thought it would also show in the status. |

Posted 5048 days ago by CodeRedDewd I updated to the latest version of BOINC, it did benchmarks and I'm still only computing at 1.0... I don't know what else to do. |

Posted 5048 days ago by CodeRedDewd I updated the driver to the latest one from nVidia to 257.21, rebooted and it is still computing at 1.0 capability. What else can I try? |

Posted 5048 days ago by CodeRedDewd I restarted my computer and it still shows the task running at 1.0, but in line 13 it shows cc1.3 as you said it should |

Posted 5048 days ago by CodeRedDewd Is there a list of GPUs with a corresponding compute capability? I've been looking for one and can't find any. I had a 9800gx2 that was compute capable of 1.1. Thought the 280 was highter. |

Posted 5128 days ago by CodeRedDewd Sorry, but I have to say that on my system, GPU tasks don't run to completion, as I have one Collatz that ran 16 of 45 minutes, then switched to running to 2 GPUGRID tasks, from one of each. Maybe something isn't right because it does this? |
