Nvidia SLI

[Lil Scribbles]

So I just got a great deal on a EVGA GTX 970 4gb, and wanted to use it alone side my current GPU MSI GTX 970 4gb. So from what I understand I should be able to use both within SLI. It recognized both cards but it does not see that I have an SLI brigde installed. I have tried more than one bridge. I have looked over everything on my build and everything does support SLI. And before anyone asks yes I have tried to enable it in the 3d settings but it is grayed out because of it not seeing the bridge. Please help, this is my first try at SLI and I would love to get it up and running.

I thought SLI only allows the main card to be connected with monitors?

I thought that as well, I can use ether card for ether monitor I want, but per the manual only using the card in the PCI slot one.

Are you sure the bridge is functioning?

Try disabling PhysX, and see if the option to enable SLI appears.

The issue is not the bridge I have tried using more than one

Are you able to disable Physx?

What mainboard do you have?
EDIT: Nevermind, didn't read closely enough... Oops...

Well you can set it so it isn't using a dedicated GPU for it, which yours is currently.

Click the little drop down box that says automatically.

I suspect that your issue lies with the two different card manufacturers. There is something in the SLI info sticky thread that states this actually. Here's the link. It will be the second spoiler.
