How dose sli work with different gpus

[aconfusedpcgamer]

so say i have a evga 760 and a windforce 760 there bothe at the same clock speed and memory could i sli them even tho there different manufactures ?

It should work, as they are both the same exact GPU.  If one does happen to be faster, it will just automatically slow itself down to match the slower one in terms of speed.

I’d wait for someone else to confirm but I’d say yes you can. As long as they are the same memory, clock speed, memory speed, interface etc. Basically they need to be identical but I don’t think manufacturer should matter.

 

As I said, I’d wait for someone to confirm who definitely knows.

They're not different GPUs, they're different graphics cards using the same GPU chip. Even if they're not the same clock speed (memory needs to be the same), you can SLI them as long as they use the same GPU.

Yes that is perfectly fine, and as for different speeds they will just be set to the lowest common denominator of the cards used in SLI.

Memory speed, clock speed, power consumption and such can all be different. What matters is the GPU and the memory capacity. Different board partners will work together no problem.

Nope. It will match the lower one. The most important one would be, if you use a 8GB and a 4GB, you'd be losing 4GB of VRAM.

They’ll work, but if your gaming it’s probably not worth it, depending on the games you play

There we go then

With Nvidia (unless they've changed it, their documentation is often out of date), you can't run an 8GB and a 4GB card in SLI at all. With Crossfire, it would match the 4GB card but SLI just doesn't allow it.
