Many thanks my friend. A source of comfort to be sure when navigating the high seas! I think you are right about ATI. I was talking with my son who is all gaming and nothing else. We did the numbers recently and could only conclude his best bang for the buck was ATI by a mile and he didn't have many bucks to spend. I was disappointed at how much I had to spend on some 285's just prior to the release of the 4xx cards. Looking back, I can see I paid less than they are now going for - when you can find them. Should there be an applicable SETI app with sufficient WUs to crunch I would happily invest in the 58xx series - I'd be spending less and getting more! Ahh the market place. You gotta love it. Merciless when it comes to the small guys. Regards, |

ATi doesn't seem to scrimp on Double Precision with their 58xx cards, While Nviduh does, Just to keep their more expensive dumb commercial junk alive. Even the 5970 is looking better, That's ATi's newest equivalent to the GTX295. Of course they ain't cheap, In fact the price has gone up since I last looked. It would under ideal conditions take Me 4 Months just to buy 1, Let alone 3, Wow. :D The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Double precision is only worth it, if it is needed. It's a bit like buying the latest all singing, all dancing 10 decimal place scientific calculator with graphical output, and then only using it to check your bank balance. |

Double precision is only worth it, if it is needed. I have looked for the post, which was several years ago, but I believe MB only requires single. Seti needs accuracy but not precision was one quote. When the validation is done it checks that the tasks agree on a spike at a frequency and that they are approx the same strength. |

check your numbers No 200 series Nvidia card is an equivalent to the 5970. My 5850 runs circles around the 295 on collatz, Milkyway, and DNETC. Heck my 4770 kept up with the 285's. It's readily apparent that ATI has a much better card all around than the Nvidia. Now the 400 series may bring them back, but we won't know until they get an app that works for it.

I meant in the number of gpus per card, Not in the way You meant, But that's ok, I know the 5970 is faster, Even If Nviduh made a 295 like 400 type card, Would It be as fast as the 5970? I don't know, probably not, I'd have to wait and see really, A die shrink couldn't hurt Fermi though, It could use It. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

GPU Grid is the sole project that is reporting that these kind of stats are inverted ... that is to say that the ATI application is about half the speed of the Nvidia application ... the best news is, however, that they are supposedly getting some AMD assistance in optimizing the code for the ATI cards ... it may be that the programmers there are just not using the cards well (yet) ... For those of us that like the project yet are migrating to ATI cards this is good news ... |

Just a suggestion. If more people with these cards would attach to beta and test if the app for them there works, it might be released sooner, then we'd get code sooner & see what changes are made... a cycle you see. Point me in the direction and I would be glad to test. My 480 isnt good for much else right now (as far as this project goes, my systems primary focus is my use including gaming). I would be glad to spend my cycles testing... |

I attached to the project but I keep getting a error.... No work sent... You computer has no ATI GPU... LOL!!! Test results: Stating the obvious... CHECK! |

Bets does the same thing. Imidiatly goes to 100%. Its running cuda_fermi but not working right. At tjhis point I am going to back dawn from any serious SETI crunching. i will still leave my clunker P4 crunching for now though its not going to crunch all that much. Thanks your your time... |

then you are confirming through the beta work that the app isnt ready for regular use here. you are doing the right thing by being a tester on beta. You are actually helping get things going faster In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

He's probably expecting Eric and the nVidia developer to crawl through threads on the main project to look for things like that. And then beta testing is a little more than posting "it jumps to 100% and so I am leaving here, bye!" |

you are doing the right thing by being a tester on beta. You are actually helping get things going faster Excuse me?? First off I didnt realize there was a "beta forum", thanks for clerifying that. Second yes I shut down because I am not going to flood the place with errors, what should I do? Keep my system cranking out erronious work units all night long? I would expect that would make things worse on their end, dont you think?? Thanks for your input though, greatly apreciated! |

You are actually helping get things going faster Well, the link that WinterKnight gave you for joining the Beta project did lead to a standard BOINC 'front page' with, among the usual links, 'Message boards' - aka a forum. Could I suggest - nay, urge - you to read WinterKnight's excellent Please Read Before Posting, which gives an introduction for new users to the expectations and etiquette (on both sides) of Beta testing. Not to say that the project always lives up to these high ideals... |

Second yes I shut down because I am not going to flood the place with errors, what should I do? Keep my system cranking out erronious work units all night long? I would expect that would make things worse on their end, dont you think?? That's beta testing. Run all work, post about the errors you get. In this stage of developing, they'd rather be flooded with errors, as how else can they find whether the app works on people's systems or not? And wouldn't you rather have that a sturdy app is released on the main project, not one that crashes 90% of the tasks? Not that that's any different than what the regular app is doing at this time. ;-) At least by posting on the forums there what errors you found - and preferably different ones, there's no use in posting the output of 17 tasks if the error is the same for all 17 - you can slap yourself on the chest when the app is finally released here and say "I helped develop that!" |

I would expect that would make things worse on their end, dont you think?? I see. I will fire it back up and let her rip once I get home. Thanks so much for the info. You are a great help. one final question, where do I find the proper place to post my results/errors? Thanks agian ;) |

One final question, where do I find the proper place to post my results/errors? Errors with Fermi would be a good place. Don't worry about the "& AP" on the end of the thread title, you'll only be reporting on SETI@home Enhanced with a Fermi. |
