1060 with 660

[NanoSuit3]

I have a GeForce GTX 1060 MSI Gaming X 3GB in my system and its running like clockwork but I want to make it run better so I decided to put an oldy in it; my GeForce GTX 660 EVGA Superclocked Edition. I put it in and try to utilize it to run EMA but it's not working. Is there a reason why I can't run these two Cards together or am I missing a point here??

Afaik, you can only SLI 2 cards if they are the same. Brand doesn't matter.

E.G. EVGA GTX 1060 and MSI GTX 1060 but not EVGA GTX 660 and EVGA GTX 1060.

You also need an SLI bridge + SLI compatible motherboard.

If I'm wrong, can someone correct me.

You're right about being the same GPU chip to SLI. If one is faster than the other, it will slow down to match the slower one too. SLI Bridges may or may not be required. I think it depends on the exact GPU and motherboard combination.

In this case, neither the GTX-1060 6GB nor the GPU cut-down version GTX-1060 3GB, is capable of SLI. (NVidia decided to reserve SLI for the GTX-1070 and up)

About the only way to use both on the same machine is to dedicate one to GPGPU/Cuda/PhysX use only.
