I've been crunching for the last 3 days theese new pair, 5101 and 5102, they are the worst I have ever worked with but especially 5102. They both worth 2165 points but the latest has 65% more atoms than the 5101.
5101 --> 1700 PPD
5102 --> 1060 PPD
This is, one more time, ridiculous.
Running here a a Q6600@3.4 ghz and two SMP console clients on Kubuntu. Even a pair of the hated 2665 produced here + 2000 PPD each.
P.S. I've sent results for at least 3 of the 2665 WU's in the last week and haven't received credit for them, but this is another story.

100fuegos,
I still remember when you passed me up in 2005-ish.
It's time to give up on CPU folding. My 8800GT is outpacing you now. Get the NVidia CPU2 client. Maybe you can still save a couple cores for CPU folding?

Nah, I can't afford to buy a G80 now just for foldng neither the increase in the electricity bill it would bring with it.

They listened to us and uped the points for the 5102 WU only. In any case should be around 1700 PPD only way lower than 2665 or 3605.

I don't know what you all are complaining about. For the last four weeks, my weekly production has gone down from around 28K point per week to around 17K points per week.  I have pretty much been only getting 2665's. HTPC is an X2 4400 with a 25% overclock and a single SMP client. SMP1 and SMP2 are running on a Q6600 at 3MHz. Both machines are running XP and I have AffinityChanger runnning on the Q6600. |

Newegg has a Gigabyte 8800gt that is $77 delivered after a $30 rebate. It only has 256MB of memory. I wonder what that would do to its folding output in comparison to a 512MB card? Anyone care to hazard an opinion or guess? At that price, I could pretty much build a folding rig out of spare parts. I would probably put it the basement. |

most of the newer smp projects require at least 512mb and the recommend 1mb per client,

Yeah, looking around the FAH forums, there are mixed opinions about 256MB cards. I wonder if all of the memory has to be on the card, or if it can use system memory - you know the allocation you make in the bios for texture storage and the like? 1GB 8800GT's are two bills and up.
It also looks like having an 8X PCIE bus slows things down in comparison to a 16X bus, though I could find no comments on how much of a difference it would make.
I can pretty easily pull a board from the couple of hundred I have sitting in the basesment with a PCIe video bus (but almost certainly 8X), put an inexpensive CPU in, a gig of memory, a used drive and so on. Put a wireless card in, keep it in the basement and manage it through VNC.
Anyway, it sounded like an interesting idea.

You should do it. Call it an exercise in building a cheap folding rig. Maybe it'll inspire others to do the same--take spare parts, a cheap <$100 GPU, and enjoy the thousand plus points every day.
Maybe even make a short article / guide out of it?

Never mind the aperture size comment. PCIe cards do not use it.
Babar, I think I am gong to hold off. What I suspect happens with 256MB cards is that a good deal of system memory is used. As the size of the WU's increase, this will only become more so. You could end up with a fair amount of thrashing going on between system memory and the card's memory, which might greatly reduce performance.

Acc'd to the Folding site: http://foldingforum.org/viewtopic.php?f=43&t=3193there isn't much difference between a 256MB card and a 640MB card, it's more dependent on GPU type, GPU clockspeeds, and CPU clockspeeds than it is on GPU memory. |
