Thanks for the reply. There list is out-of-date because the current version of control center is 10.2 |

You can't use the ATI cards for Seti (yet). It should work with Collatz though. |

the onboard isn't capable of running in crossfire mode. you need to have 2 ATI PCIe Crossfire compatible cards to run in Crossfire mode. the onboard GPU is going to be a bit slower than a PCIe card of similar rating. You can probably set up an optimized app to run Astropulse in the ATI gpu but the AP WU's are few and far between. Better to do COllatz on it. At least you know you'll actually be doing some work instead of sitting idle ![]() In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Their board actually does support crossfire with the onboard chip. However, I don't know if that is really important to running BOINC projects. Somewhat like SLI needs to be disabled in NVIDIA cards for everything to work correctly for SETI. SETI@home classic workunits: 93,865 CPU time: 863,447 hours ![]() |

I just picked up a pair of these with the DDR5 @ frys for $80 a piece...couldn't resist giving them a shot. It's going to be a little while until the RAC stabilizes, but so far it looks like they are knocking out a WU in about 35mins a piece (196.21 w/ Lunatics Unified 0.2) That about inline with what you guys are seeing? |

It looks like that OPT app for GT 240 is not happiest (fastest) solution. I am cruncher :) I LOVE SETI BOINC :) |

Hmm, where did my post go?! OK, I have detached from project, uninstalled BOINC, Re-installed without using the Lunatics unified installer and now Cuda tasks are running in 20 mins instead of 4 hours, but CPU tasks are giving a rather ridiculous 20 hours ETA, rather than the 4 and a bit I am used to! It shouldn't be this hard, should it?! LOL |

You CPU task compute long because stock application is slow compared to opt application from Lunatics installer I am cruncher :) I LOVE SETI BOINC :) |

OK, I used their Unified installer before because it's been a very long time since I had to re-install and have forgotten how to install the optimised ap - and the Lunatics website is making it non too clear at the moment! I want to install the optimised CPU app, but not the CUDA app as that clearly has compatability issues - any pointers anyone, please? |

Hi, but you can also run CUDA stock and optimized for CPU, you can define that in the app_info.xml, or am I totally of coarse? Never actually tried it, cause there wasn't any need for. Have used the 'Unified Installer'from Lunatics, the last times, it makes things so much easier, only have to change to CUDA 2.3 i.e. 2.2 and the right* card-driver's. *( Not every card, appears to works well with the same drivers.) Maybe the CUDA version and card driver # , does not match the card, used. I've noticed some 'strange'things, with the 196.21* (one higher, updated). Screen slowly receiving white pixels, until the whole screen is white (R,G,B;255,255,255) So I reverted to 18x.xx .(Writing this on my LT) Think, that happened to anyone, Andy, (first) trying the Optimized app. and writing the app_info.xml file, I wouldn't worry, they'll get resend and you'll get some new ones :) ![]() |

Andy can you clarify what you did? Did you install the CUDA via the Unified installed and just override with the Cuda 2.3 drivers? I seem to be having the same issue you were experiencing a couple posts back with Seti tossing all of my cuda WUs |

wow, that made a hell of a difference, good call. Seems to be running cuda about 4x faster |

I read that this card takes about 70 Watts. My PSU should be able to handle this.. hmmmm in 24/7 mode how much RAC increase could I expect (all as optimized as one could get it offcourse ;) ? The SETI@Home Gauntlet 2012 april 16 - 30| info / chat | STATS |

It can take 70 WATT,but that is in peak. Since your card WILL NOT be used 100%, you real power cosumption will be at max about 50 - 55 WATT. That is value I get when I monitor my computer in idle, and when GT 240 compute SETI. I am cruncher :) I LOVE SETI BOINC :) |

50/55 Watts, even better :D Do you have any idea what this card would do for RAC (24/7 mode)? (this could motivate me enough to buy one ;) The SETI@Home Gauntlet 2012 april 16 - 30| info / chat | STATS |

I have two of these cards running on Windows 7 x64 combined with a i5 750 I get about 10k - 12k RAC, its a bit low at the moment as im still recovering from long downtime. I only have this machine on from like 8am - 10pm as well so running 24/7 you should get alot more RAC! Overall I think they are pretty decent cards for the very low cost! D Cheers D ![]() |
