8800GS not performing

I picked up one of the XFX 8800GSs that the purple shirts were selling off recently. It's somewhat disappointing as it's only giving 3200PPD instead of the 4000 I expected. It's a 65nm R92 with 384MB RAM, it's the only card in the PC, drivers are 181.20, OS is XP32 SP3. My 9800GTX+ gives 5800PPD on the same WU which is spot on.

I'll try the 8800GS in place of the 9800GTX+ when I get a moment, just to see if there's anything other than the GPU slowing it down.

BTW the 181.20 drivers are great for XP users as the folding CPU usage is now almost zero.
 
Is the GS overclocked? The current units are a bit heavier on memory requirements and you really need to push the GS to get it to perform in my experience.
 
That's about right for the GS with the current WUs. They are not the value buy they were 2-3 months ago. 8800GTs are the way to go imo.

With the old 480 point WUs my GS and GT got the same ppd but now the GT gets around 400-500ppd more at the same clocks on the 384 point WUs.
 
I have 2 8800GS cards. I only get 3000PPD with them each.
In the same case i also do have a 9800Gx2 which might be some how effecting my Total PPD from my GS. Only way to find out would be to remove the 9800 from the case.

Try overclocking the card and let us know how it goes. Might be worth while just testing the 8800GS in the case on its own. And let us know how you get on.
 
3200ppd is spot on for a stock 8800gs
crank the shaders to 1870-1900
the memory up to 900 (higher if possable as biffer said it has more effect now)
and the core to 600 (if you have reasonable cooling)

that gets me 4100ppd :) on my 8800gs

check out my production graph here did a reboot at work and forgot to reset riva (which I did yesterday) 7 days at stock :(

If I remember correctly the 181 drivers give lower ppd (10% less) but as you said snapshot, they do use less cpu time (But don't work with AutoCAD)

Muppetkiller - i think the driver choice depends on what else you will use the pc for. I use 180.6 becuase they have some game bug fixes, but i think the 178.28 drivers (what i was using before) were actually a little better for folding. I have not tried many other driver options, but i think it is better to go with the dedicated CUDA drivers.
 
Well, that's been an interesting few hours. This card seems very overclockable as I've currently got the core at 700MHz, memory at 771MHz and shaders at 1902MHz which gives me 3997PPD. It may well go further but I've spent long enough fiddling with it. The temp's only 71C at 30% fan so there's plenty in reserve if I can stand the noise....

I did have the 8800GS in the same PC as the 9800GTX+ and it only gave 2500PPD then.

The 180 series of drivers cut the PPD compared with the 170 series. I tried the 180.60 CUDA drivers but found no difference at all between them and 180.48 & 181.20.

Thanks for that info Chrissy + Snapshot.
Will try differint drivers tomorrow. As i dont use my folding machine for gaming i dont mind how far back a driver i use. But will give the Cuda driver a go first.

Also nice overclocking on your GS snapshot, them shaders went well hight. My GS cards will only go to 1800 then unstable. But my ram can go upto 1000.
 
Just picked up one of the old 5015 WUs and, in its overclocked state, it's giving 4880PPD. Shows what's possible when there's enough on-board RAM. :D
