Problems getting Folding GPU to work

post #1 of 12
Thread Starter 
ive got my setup in my sig, the HD5850's in crossfire with a 9800GT as a dedicated physx card. ive hacked the drivers, and i know physx is working because my CPU score doubled in Vantage. but when ever i try to use folding@home GPU it comes up saying no supported GPU detected.

only other problem im having is the game Mirror's Edge gets heavy tearing and jaggered grey triangles when Physx is turned on. also when physx is on my frames are really low and when it is off my frames go way up.

hope someone can fix this, i got the 9800GT mainly to fold for OCN

Give us some info on what you have set up.

If the 9800GT is your third card, your going to need the following flag along with the proper 'start in' folder:

-gpu 2

And since you're running hacked drivers, you might want try this flag, it'll override that error.

-forcegpu nvidia_g80

Add a space it is -gpu 2
How to add flags

If those flags do not work you may need a dummy plug or reinstall the drivers.

so how would i go about adding both the -gpu2 and -forcegpu flags together?

Error says exactly this "At present your GPU is not supported or you need a current driver. You may want to consider running out standard client, which you can download at folding.stanford.edu."

Just need to space it properly, here is an example.
\\Folding@home.exe" -forcegpu nvidia_g80 -gpu 2

The order shouldn't matter.

When you open up GPU-Z is Cuda showing up for the 9800gt?

Yea your drivers are not installed correctly, that CUDA needs to be checked.
