SLI + 3rd card - not for physx

post #1 of 9
Thread Starter 
Can this be done?

Currently I have SLI 670's powering 1 monitor

I want to add a 2nd monitor for temp monitoring and web browsing but I don't want to break up my SLI. Can I add 3rd video card for this?

So the 670's would be SLI enabled to power my primary monitor
the third GPU, say a 240 or something like that, would be used for web browsing,monitor temps.

I wanted to just use on board video, but apparently that can not be done.


The FAQ briefly spoke about this, but not really this same question

Yes you can, all you need to do is install the card and then plug in the monitor, after that you need to go into your Nvidia control panel and make sure that the card hasn't decided to take the Physx role and it should be fine.

you can have 2 screens without breaking up the SLI (ive had a dual screen setup since forever). I've done it like 4 generations already with both amd and nvidia. you don't need a third graphics card

How do I do this? I tried last night and the monitor only displays an image if I have SLI disabled - I did however have that monitor hooked up to the 2nd card while my primary is hooked up to the first.

my 480 SLi setup running two screens



afaik you have to plug it on the top card. it should work either way without problems afaik. never encountered such an issue with both SLI and crossfire


it's a dead given you can run more than one screen with sli. most of the pople here running nvidia surround/eyefinity have multi gpu setups

Yeah my old 470's ran two 120hz screens.

You can run 3 screens in surround by having two on the first card and one on the second.

Ether way you plug it it. Both monitors can be on top card or monitor on each card. Ether way will work fine, but nicer to have them both on the first card for videocard idling reasons.

SLI should still work fine.

Only thing you can not do is run 3 monitors in SLI while not in surround.

But as you only have two that is not important.

Ok. I'll try running both monitors off of the same card - the top card. Last night I tried it with the primary on the top gpu and the secondary on the bottom. It was working until I enabled SLI then the secondary monitor shut off
