3dsmax 2011 performance driver not working when 2 graphic boards installed

[boumay]

Hello,

I have 2 boards: quadro 4000 and gtx 560

I've had a problem installing the performance driver for the quadro as it wasn't able to see my quadro.

Later I've been advised to remove the gtx 560 just for the driver install, as it was probably a conflict issue for the performance driver.

And it worked, I removed the gtx, and the driver installed and run well in max.

But... When I put back the gtx in the pc, the driver now fails to start in max.

It seems that the confict is back

Annoying

Anyone knows what to do?

well the subject is closed I think.

I've learned that many people have this issue, I mean trying to make a geforce and a quadro working at the same time in the pc. It is actually not possible, or at the cost of having the quadro running under the geforce driver and recognized as a gtx 450 or the like, that's why the driver doesn't recognize a quadro in the system after that.
