Graphics GTX460 with an 8400GS

I am currently running two screens on my GTX460. Which means it doesn't clock down and i cant use its fully power gaming.
I recently purchased a 8400GS PCI card to attach the extra monitor and soon another. Both cards work fine on there own, but when trying to work at the same time either i get BSOD or on the rare occasion white horizontal lines of the 8400GS monitor.

Does anybody know what i need to do to get them to work together?

Thanks.

 

Maybe something to do with the AMD chipset? I'm not sure to be honest. I'm assuming you haven't connected an SLI bridge? lol

 

Nope no sli bridge. (no connector on the 8400GS) its very annoying!

 

My guess is a driver issue, have you got the latest drivers?

 

Yep latest drivers from nVidia

 

Try backdating a few versions

 

Install the older drivers for the lower spec card first... worked for my 8800 GTS + GTX 480.

HTH
