Folding help, MSI P6N Diamond

[elec999]

I got a MSI P6N Diamond, with 4 pci express slots
Q6600, 2x1GB Pc1000 ram, PCP 1000W PSU.
Windows XP
Whenever I plug in my 9800GTX+ and run folding system goes on fine, whenever I get my 9800+ Palit, in there as well the system freezes, for no reason. Freezes at different times. Tried latest beta drivers, latest official drivers, cuda 2.2 drivers. Nothing fixes it. Samething happens when I plug in my 9800GT Palit and Asus 8800GTS. I purchased this board to run multiple gpus. Can anyone advice. Latest bios. No overclock, everything stock.

The board may not be the culprit, the GPUs could be...

You said the GTX+ works.
But adding the Palit, it doesn't.
Then you said the Palit + 8800GTS neither.

Remember that folding on the GPUs puts a lot of stress on the cards, and could show instability. You know the GTX+ runs fine on its own, try running the Palit and the Asus on their own (I'd try the Asus first). Make sure the GPU temps are within acceptable limits.

How does it freeze? Is there a BSOD?

There is no BSOD the mouse and keyboard simply wont work. Sorry I forgot to add I did have the Asus + Palit running fine, if only one used, and they also worked fine in other systems.

Can you run the GTX+ and the GT in SLI, without Folding? Can you change the Auto volts settings to manual settings?

Wait so you have 2 9800GTX+, one's from Palit, one 9800GT from Palit, and one ASUS 8800GTS? From what I know, you can't mix GPU with different shaders together and expect them to run well.

The 9800s should run, albeit have an issue with ppd in regards to folding. I'm not sure about the GTS though.

That's why I'm asking if they (the 9800s) are at least able to run in SLI.

Thing that I'm really confused on my Asus P5Q Pro I run my GTX 260 + 8800GT runs fine. Runs very stable. On the MSI, I have/tried/test.
I have 9800GTX+ Leadtek, one Palit 9800 Super + 1GB, Asus 8800GT. I tried every card combo, but they refuse to run fine together. I can only run single card, otherwise it crashes/freezes (no BSOD). The 9800GTX+ 9800 Palit still crash. Asus 8800GTS + 9800 Still crashes. Asus 8800GTS + 9800GTX+ Still crashes. Might be right about the different shaders. But isnt the 260 and the 8800 different shaders too.

Have you tried a real old set of nVidia drivers, like the 177.89s? I'm thinking driver issue here.

Don't forget to run Driver Cleaner in Safe Mode if you do change the drivers.
