Thread Starter 
i've followed this tutorial on how to set it up:

http://www.overclock.net/overclock-n...a-folding.html

and when I run the folding app I get an error saying could not find cudart.dll.

You either:

1. Dont have the correct drivers, suited for folding
2. Did not run a 'driver cleaner' to remove all of the previous drivers fragments.

You can use the :

177.35 drivers, with a mod'd INI file, to have independent OC control over all of your GPU's used for folding.

180.60 drivers to reduce CPU load to minimum, when folding...losing independent OC control of your GPU's though. [ie- if you have 2x of the same cards installed, adjusting 1x GPU will effectively OC both]

i'd have to mod the ini file?

btw I'm folding on a 9800GTX+ and a 8800 GTS. would I have to have different drivers per card?

No..you dont have to mod the drivers..others have done that already. Same drivers for both GPU's

You can find the drivers you need here for d/l

**You will experience a lower PPD with the 8800GTS, due to mixing the GPU types in the same machine. Only possible way around that is to either flash your GTS to a GT..or to put the GTS in a 'nuther 'puter.

but what about XP 64bit users?

for the cudart.dll drag it to your folding directory. its usually located in your appdata/roaming folder.

if you still can't find it... you can dl it here:

^^Is this with the Windows SMP client? If so, you could use the Linux SMP client in VMware and get about another 2.5k ppd or so.
