ohhh? They were done on your CPU. |

oh i see a gpu is not required but makes the work quicker?? as long as i can crunch some numbers and do some science thats all i care about |

Does anyone know if an AMD 7970 can crunch here? |

I tried to calculate a unit MilkyWay with GeForce Titan with double precision enabled, the GeForce Titan is used only 14%, why ? @+ *_* |

The Geforce GTX Titan has a peak performance of 4500 Gflop per second SP and 1/3 of the computation units run in DP mode so the DP peak performance should be 1500Gflops. It has 2688 Streamprocessors 1/3 are then 896 for DP. |

Hi, I have the same setup, and HD6990 and HD7970 in same box with windoze 7. The only thing I had to do to make it work was make sure the 7970 was the primary card. The 7970 takes about 54s to finish and the 6990 takes about 115s at stock speeds. 8-) |

Yes it will do great! http://boinc.berkeley.edu/wiki/ATI_Radeon |

The GTX Titan should do well here; it's FP64 performance is 1/3 that of it's FP32. Have you tried more than 7 tasks in parallel?
As the top dp frequencies are lower than the top sp frequencies the maximum performance is slightly less than 1/3rd - it's 1.3TFLOPS. |

There seems to be some question at to whether or not a GT 520 card will work on this project. Just for the record, I have been using one for the past year or so and it crunches Milkyway@home WUs just fine -- also Einstein@Home and SETI@Home. I tried running two WUs at a time in it for awhile, but decided I wasn't gaining much and apparently slowing down CPU jobs because of the extra CPU effort needed to keep two WUs running in the GPU. Not sure why that is, but it sure appeared to be the case! (The machine has s dual core AMD cpu and I have my computing preferences set to use 100% of available CPUs.) |

Are you crunching a cpu project using those cpu's at the same time? If so change the setting so one cpu is left free, per gpu, then set MW to run two units at once again and see if it helps. When you also run a cpu project on the same cpu you use to fee a gpu it can slow down both projects. Since the gpu projects crank out much more work it might make sense to drop one cpu core from the cpu projects and give more to the gpu projects. |

53 to 54 seconds is my experience with that card on MW ... Go away, I was asleep |

One thing I forgot...the Admins need to edit the first post in this thread to include the cards that work but are not listed. Having to read thru EVERY post just to figure out if one does or does not work means it probably isn't going to happen. How many people have connected only to find out theirs doesn't work? |

I hope the new "Updated GPU Requirements" thread is sufficient. Please post there with comments, issues or workarounds. |

I have the GTX 260M in my alienware laptop. According to the notice I received from Milkyway at home, my cpu doesn't support double precision extension, however it is sill computing....any ideas if its working or not. |

Are you crunching CPU (processor) workunits, or GPU (graphics cards) workunits? Even if your GPU can't crunch, your CPU can still run workunits. |

Arkayn, I finally got around to installing a new driver. The version I have now is Catalyst 13.1. It's WORKING!! Thanks again, Arkayn. Max |

honestly I don't know, but I have an i7 quad under the hood. It is working, I have 4 different lines of status bar on my screen. |
