My System Specs

Default Can I fold on a GT200 and G92 combined rigs?

Is this possible? I've heard horror stories of this not working and I want to be sure since if this is the case I'll have to figure out a different plan for my 5th GPU on my Classified rig.

Originally I was going with two GTX 295s and a 9800 GT, but I keep getting worse and worse news. Some people say to try the -nvidia_G80 flag (or something like that)

I know Alwaysrun had quite the headache with this (enough that he sold me the 9800 GT)

So now I'm worried it won't work on my setup.

There is a lot of threads on the F@H forums about this;
Folding Forum • View topic - GTX260 & 9800GTX+ issue working together
Folding Forum • View topic - Does not want to fold on second card
Folding Forum • View topic - Mixing cards (shaders)...Rules?

The flag is -forcegpu nvidia_g80 and I don't think it will help. It seems you could mix with the older 50xx WU's but not the new ones. I hope somebody can come up with a solution for this...

Maybe put both in the back-up rig...

zlojack I was planning on throwing in a 9800GT as well but LCB has warned me so I am hesitating. Bought a $350 PSU this week, getting a case tomorrow, and the next purchase is a second video card to pair up with my 285. It was gonna be a 9800GT or GTX+, but now I am trying to figure out how to get a 285 in there.

My $200 folding upgrade is getting pretty carried away!

Well, I'm going to try it with my 285s and a 9800 GT before the 285s go away for step up.

If it doesn't work then I might grab a used 260 and see how it goes.

This post is really appreciated LCB. This explains some of the issues I have had in my folding box in my sig.

Looks like it is some driver issue. Looks like its another 285 in my main rig or nothing until it gets figured out.

gl guys. All I can say is don't bank on them working together. I spent 10 hours reading every single shred of info on mixing cards and folding and in the end I just couldn't get a 9800gt and my 260 to play together. If anyone knows a workaround where you can have 2 independent nvidia drivers working on the same OS I highly recommend you apply for a Nobel prize. I hate being a doubting thomas here but if you two actually get a 9800 to work alongside any 200 series card I'll eat a bowl of worms, I'll brush my teeth with cat poo, I'll, I'll...you get the picture.
