New to Cuda, video card help please

[hiamps]

I have 2 nvidia cards, one is a 9600 GSO which runs Cuda and the other is a 7900 that doesn't run Cuda that the 9600 replaced. I am wondering if I can put the old card back in and connect my moniter to that so Cuda can run full out on the 9600? Really slows my video running Cuda and using the card. I have an Asus P5N32 E-SLI Plus, Thanks

Yes, there shouldn't be any problems.

Thank you, I was afraid to try as I didn't know if they needed to be the same card and I didn't want to fry anything. Will give it a shot.

Hmmm, never easy.....I put the card back in the lower slot and restarted and was hoping the computer would just see it but it didn't. Is there a trick to getting the computer to see the other card? Maybe a bios setting I missed?

Go into Device Manager

and Click on Rescan for hardware changes

Right click on My Computer > Manage

On my 3rd restart windows found it but the video still doesn't work. Does it matter which order they are on the motherboard? Should I put the 7900 in the main PCI-E slot and the 9600 in the bottom slot? Right now I type faster than the screen can keep up with and I use 2 fingers. Once the card was found NView disappeared from my right click dialog box now I just have nvidia properties and it won't open from control panel either the icon is all funny looking. Should reinstall drivers?

Reinstalling the driver could be a good thing. Check the bios if it has an option about which PCI-E slot is primary or secondary or something like that. Also check the motherboard manual if it says something about using these two slots.

Finally took the cards out and put the 7950 in PCIE 1 and the 9600GSO in PCIE 3 and all is good. Thanks all.
