Questions about connecting 2 Nvidia Graphics Cards?

post #1 of 14
Thread Starter 
Question 1:
Is it possible?

Question 2:
Do they work together to power all monitors, or only the one each one is hooked up to? I want to know this because I would be combining the power of two differenct Nvidia Geforce Graphics Cards.

Question 3:
Is there a tutorial on how to do in anywhere?

1. Yes, but you can only connect 2 of the SAME nvidia cards in SLI in order to have them work together.
2. Yes.
3. Make sure you have another PCIe slot available, any external power connectors, and a SLI bridge. Then you can enable SLI in the nvidia control panel.

1. Yes.

 

2. Because they are not in SLI Surround, the second card will be as an extension addtional output port for extended desktop display.

 

3. Plug the second card in, reinstall Forceware, go to NV CP to assign the second card as dedicated PhysX to avoid possible conflicts.

Is there anyway I can have a three monitor set-up with a GTX 570 then? Is there some type of spitter or something?

While you can buy a splitter it will just project the same screen.

if you are looking to add a third monitor you can add a cheap nvidia card to just run the monitor.
Small wonder.

As far as I know just plug the 3rd monitor into the 2nd card.

Very much so. Only 2 cards of the same kind. Aka 570 and 570, 450 and 450.*

*Unless you have a special chip on your mobo called hydravision or something, which I can almost guarantee you don't, and It's not very good, and it's not really sli.

Well do you think 2 GTS 450's would make up the power of 1 GTX 570?

Also do you think it would nicely power 3 monitors?

No you dont have to run sli all you have to do is plug in another card and reinstall drivers your 570 will still be the main and your 450 will just power the other monitor.
