Hey guys,

 

I have a reference gtx 780ti, and I am planing to go with a second one soon.

My question is:

Can you SLI same graphics cards but with different pcb?

For example: reference gtx 780ti  +  gtx 780ti classefied edition

or

                      reference 780ti  +  gainward gtx 780ti phantom

 

Thx

So long as you have the same GPU configuration you should be fine. Two GK110's with 2,880 CUDA cores.

 

If one card is faster it will be clocked down to match the slowest card.

Yes. You can put those two cards in SLI. The things to look for when looking for SLI compatibility are these: Same chipset, same amount of VRAM, and same bus width.

That might be true out of the box, but I've had two 660 Ti's run at differing clocks when I overclocked them.

Really? Interesting.

Yup. I couldn't get them to even out unless I reset them. Once I overclocked them, one would start hitting higher values than the other.
