Running 2 Nvidia cards, non-sli, multi monitor - possible?

Hey all

Just wanted to see if I can connect more than 2 monitors by adding another graphics card to my pc.

Primary card is a Nvidia card and the second is also an nvidia card.

I've got 2 monitors connected at the moment which work fine, however a third is not connecting via the second graphics card.

windows shows code 43 error, which Googling seems to be driver related but I'm not sure if I can install a 6600GTs drivers over my 9800GTX drivers...?

Complete newbie to this, if anyone could help that would be great. I've been told it can work, and there would only be a problem if it was mixing Nvidia and ATI.

Thanks :)
 
You will need Windows XP or Windows 7 for this IIRC Vista doesn't work (even with 2x nVidia cards I think it has problems).

For normal desktop non 3D useage you can connect 2 monitors per nVidia GPU in the system even without SLI.
 
I'm running Windows 7 now, tried rebooting several times and no result.

The 2 on my 9800GTX work fine, just this addition of the 6600GT is not working, code 43 error but I can't find a way to get it to work.

I'll try and update to newest drivers, although I'm fairly up to date already.

If anyone got anything I could try, please post :)
 
You shouldn't have to install the drivers seperatly btw - if you install the driver package once it should setup the components for every nVidia card found thats compatible with that driver. If the 6600 isn't supported in the same package as the 9800 then you may be out of luck but IIRC they are still supported in the same driver.
 
abit ip35 pro and a ocz 700w (only the 9800gtx+ needs power).

Still not working, tried to disable and re-enable both cards.
 
Your mobo might suffer "Gen 1" graphics card issue, so try to get any Gen2 PCIe graphic card (like primary GTX 9800) and check if it works. You may also try to check if 6600 works as primary card - you should know if it's Gen1 or Gen2 then.
 
So the pci-e isn't working with the 6600GT?

What about a PCI card, would that work? I'm only after 2D usage on the 3rd monitor.

Specs State "The main PCI Express x16 slot works at x16, but the second PCI Express x16 slot, works only at x4" - Does that identify Gen 1 or Gen 2?

I doubt PCI-e gen is the issue - the only known compatibility problems there are a small number of PCI-e 1.0 motherboards that don't like newer GPUs.
 
Yes you can without SLI enabled, well at least I did with 2x GTX280's giving 4xDVI connections all 4x 24" Dell ultra sharps worked but obviously not for gaming :)

DeadMan: LOL, it looks like my good, old workplace in stockbrokers, hundreds of monitors ;-)

Gangster: try to pull off 9800GTX and put alone 6600 instead - if PC boots up fine it means it's not the Gen1 issue.
 
just an update, booted up with the 6600gt and it works ok - however the win7 can't 'recognise' the 6600gt as a graphics card and utilise it, its offering bog standard low resolutions just as if I have just formatted the pc.

Anyone got any solutions, I've tried to install the driver and it appears that the nvidia control panel isn't popping up - almost as if it can't install anything because it thinks no nvidia card is there.

The error code of 43 is still appearing :(

Click to expand...

Did you try the newest drivers (260.89) with fresh install option ?

I believe you've got the latest BIOS installed :
