I went ahead and swapped out my 3950 for my older 8800GTS and now that system is getting 3400 PPD ^_^ and that system would cost about $400-ish to build nowadays

at the current rate, I should be ranked 36th in the team within 30 days

Update:
I moved the 8800GTS into my main computer, and I'm trying to get multiple GPU-folding to work on the 8800, and the two 9800GTX cards. One computer should provide about 13000+ Points Per Day ^_^ (but my power bills are going to spike....)

Update: I'm currently getting 12700 PPD with one computer. I have both 9800GTX cards and my older 8800GTS 640MB card all chugging on folding at home. I'm almost wishing that I had a 680i motherboard with 4 slots rather then my current 780i motherboard with three PCI-E slots.


Whenever I'm playing WoW, my PPD drops from 12700 down to 9570

Can't believe I didn't pay enough attention to notice that Nvidia cards are supported now!

Just put the GPU2 client on my desktop, which should add an extra ~3500 PPD to my contribution. I should have a PS3 to add into the mix here in a month or so, as well :D

Yeah, me too. I had an 8400GS on one machine that I forgot about, worth about 350ppd and I've just added a couple of 8800GS's that should bring in about 4-5k per day :) I had hoped to put one into my Q6600 machine but for some reason the system wouldn't boot up with it in :(

The only downside is that I'm taking a couple of machines off for a while.

Have an xSeries 3650 with 2 3.0ghz xeons and 4GB of RAM about to come online here--will be churning out some SMP units in the next day or two as well :D That should help too!

I have been running the GPU2 client with a "stock" factory overclocked GeForce 8800 GT. I decided to overclock it to see what kind of PPD gains could be had. This is what I found:

Factory Card:

GPU: 650 Mhz
Shader: 1620 Mhz
Memory: 925 Mhz (1850 Mhz)

Overclocked:

GPU: 675 Mhz
Shader: 1725 Mhz
Memory: 1000 Mhz (2000 Mhz)

Results (according to FahMon):

Overclocking the GPU, shader and memory individually only resulted in ~ 1 second less per frame, or about + 88 PPD. Overclocking all three components together, however, resulted in 4 seconds less per frame and + 354 PPD. All of the testing was performed on the same WU. Of course, other work units will invariably have different PPD gains.

If you are not folding on a dedicated machine, for example, one that gets used for other daily tasks, the PPD losses can be quite significant. Some situations that I tested out on the same WU were:

Browsing this forum: - 183 PPD
Watching a video in media player: - 613 PPD

Running the GPU2 client in addition to the SMP client resulted in absolutely no PPD loss at all. Apparently the GPU2 client uses very little CPU time. I might try to overclock this card a little bit higher without nuking it. A gain of + 500 PPD would be nice.

The next version of the GPU2 client should be able to run with almost Zero CPU time according to Prof Pande. I guess that means that the core you have to reserve to run the GPU2 client should come back into play.

I hope that an OS X version of the software comes out soon, I want to put the 8800GT in my mac pro to good use..

It's still too hot where I live to fire up the gaming machines and leave them running Folding at home, if I do, my room becomes an inferno, but once it cools down, all of my Graphics cards + computers will get back to folding

Just signed up for electric service at my new place (move in about a week and a half), was able to get a 100% wind power plan :D So, I'll be folding green now!
