Thanks Firehawk. So I was thinking, the calc methodology I proposed won't work on the 400 series where people are running multiple units. You'd have to multiply the result of that answer by the number of units....and then it would be close. Less accurate but close. |

It locks out edit after an hour....I assumed I could do that to, but it appears I can't. Couldn't you get mods to add this link to the first post, that way it's easier for all? :) |

I hope the ATI cards will figure when SETI can run on these GPUs? Anyone hear anything promising about this? I'd rather look for E.T. with my 5870 than map out where he lives doing MW! :) Also, anyone know if Knights Corner will be an upgrade possability for crunching WUs? I guess it would need to have an app made for it. Brent "All truths are easy to understand once they are discovered;the point is to discover them."

I'm not sure who the mods are, but if any are watching maybe they could do that. Add the link to the first post in the thread. Cthulhu: I agree, it'd be nice to use Radeons. I'd probably drop Nvidiva completely if I could use ATI on this project...It's the entire reason I have Nvidia cards. R |

BTW. Like I mentioned already in this thread. I don't think that the new Cr.-system is finished balanced. My OCed GTX260-216 make an AR 0.44x WU in ~ 500 secs. In past this WU got ~ 82 Cr. This would mean a RAC of ~ 14,200 . Currently I see much values out of range. So maybe the currently made calculations of RACs could be wrong. Maybe someone with knowledge about the new Cr.-system could jump in here? |

I was hoping we could get some recent results with the modified credit system where possible. Until that happens historical data will have to do...again precision is not likely, but +/- 15% would be great. As for getting the link moved...is NEW THREAD the only option???? Can I embed a webpage into the forum, not just the link? |

Embedding a website is frowned up, if I recall correctly it is to heavy of a load on the server, a link is ok so. Pluto will always be a planet to me. Seti Ambassador Not to late to order an Anni Shirt |

This is what I got for my Gainward GT240, 512MB GDDR5, with - GPU: 600 - Shaders: 1750 - Memory: 1800 - TDP: 70W Based on the last 25 results my RAC is 8541 (14931 seconds for 1476 points).

cool, will add to list I've done another run on the 460, got just under 15,000 this time...tried it with a different set of units, got 12,000 again. Inconsistent so far. |

It locks out edit after an hour....I assumed I could do that to, but it appears I can't. I'm mentioned on the upper mentioned site.. X-D Maybe, you should mention OC also in the table. A stock GTX260-216 have - ~ 2,000 RAC (~ 12,000 RAC), I would guess. What's with the 8,245? If I calculate with the old 82 Cr./500 secs. I get ~ 14,200 RAC. Also I let run the stock/original MB 6.09 CUDA23 on my system. No optimized app.. ;-) It's the fastest on my systems. Why? Small look in my profile the mentioned test in the 'quick instruction'.. :-) |

@Sutaru, that 8245 for the 260-216 was a result from Tim Norton...It seems fairly low. Perhaps he hit a chunk of VHARs or something. @VW Bobier, are you getting similar speeds to Frizz with the 240? R |

Ahh.. O.K. . Small example what I meant with the new Cr.-system isn't finished balanced: Same AR WUs: 0.421379 http://setiathome.berkeley.edu/result.php?resultid=1682714441 - 137.38 Cr. http://setiathome.berkeley.edu/result.php?resultid=1682714470 - 103.31 Cr. I don't know, maybe currently isn't a well time for to make RAC calculation..? Or the new Cr.-system could give different Cr./same AR WU? |

@Sutaru, that 8245 for the 260-216 was a result from Tim Norton...It seems fairly low. Perhaps he hit a chunk of VHARs or something. How is 648MHz(gpus)/1397MHz(Shaders) on the GTX295 sound and yes this is on air with the fan @ 100% with a desk fan aimed at the case. I can complete a cuda WU in about 14-15 minutes and I'm using the 258.96 Nvidia XP x64 drivers. Oh and the ram is @ 1008MHz and is stock for this EVGA CO-OP card.

@Sutaru, that 8245 for the 260-216 was a result from Tim Norton...It seems fairly low. Perhaps he hit a chunk of VHARs or something. @Sutaru and @razamatraz have redone some results on the same card and average RAC has increased from the 8245 to 10222 using the calc Razamatraz suggested - increase is probably due to increasing speed to 650 from 630 but this only affects part of the results the new result is over 194 wu rather than 57 for previous result there are some reasons why @Sutaru has a much high estimated rac for his GTX260-216 its more over-clocked than mine at 680 vs 650 i have turned down the memory to 700 and Sutaru has his at 1500 - done to save power the inconsistency of the credit system - looking at the two examples Sutaru lists there is a 25% difference he is using winxp and i am using win7 with different drivers looking at Sutaru's run times i.e. GPU secs per wu for a normal wu i get approx 1000 to 1100 sec Sutaru gets 500 to 550 secs - logically if the credit system was consistent my rac should be half Sutaru and so his estimate of rac of 15k vs my original of 8k is about correct? but whats also interesting is that VW Bobier is getting run times of 14-15 minutes (GTX295) compared to mine of 17-18 which is more what you would expect - 500 to 550 sec is more GTX460+ territory? There are a lot of "types" of GTX 260-216 out on the market - some are highly over clocked with from the stock 576mhz up to 700+ again this will add variations to the scores after the outage i will change the overclock and memory speed on this card to see if it changes the results significantly - originally thought that the memory speed for SETI on the card did not matter that much but that appears not to be the case - i used to run Milkyway and Collatz on the card and i think thats where the idea of turning down the memory speed came from also i may then try changing my drivers to the old ones Sutaru is using to see how much difference that may make if they work on Win7 if the results are consistent then i should be able to get to within say 10-15% of the high rac Sutaru is getting as my card will not go beyond 650mhz it will take a couple of weeks to get enough results with a) higher memory speeds b) older drivers 190.38 that Sutaru is using the machine which the results are from is a dedicated cruncher so not affected by other factors Tim |
