SLI Troubleshooting <3

[Choony]

Just wondering how SLI works. I'm planning to run a ASUS STRIX-GTX970 in SLI with a different card. Is this possible, a card like the GIGABYTE GV-N770OC-4GD GEFORCE GTX770 is what i'm looking at. Just wondering and thanks in advance ^.^

No. Same chipset = SLI is A-OK.

Different chipset = keep dreaming it ain't happening.

You need another 970 for SLI compatibility.

So 970 + 970 is the only one that works?

For SLI, yes.

 

Crossfire is different however.

Ok thanks for solving my problem! Will just purchase 1 970 for now, may upgrade to sli later

Similar cards need to be used for SLI to work, and Crossfire as well - although to a lesser degree. Example: You need two 970s for SLI to work. In addition, they need to both have the same amount of VRAM(as of right now, this isn't a problem. I've only seen 4GB variants). However, they can be from two different companies and have two different coolers. This means you can pair a Gigabyte Gaming G1 970 with an ASUS equivalent and it would work perfectly fine.

 

I'd also like to add that you can use similar cards with differing amounts of VRAM if you use a mod called Coolbits. This enables you to reduce the amount of VRAM(in software)on one card to be in line with the other one, thereby enabling SLI functionality.
