Overclock each card in SLI?

Trashcan · December 17, 2013

I ordered another 660 Ti yesterday, and I was wondering if it's possible to OC each card? Or do both cards need to be the same core clock and mem clock?

I believe they have to be at the same, cause when you sli/cf 2 cards with different clock speeds that faster card slows down to the slower clock speed.

I believe that if you have multiple cards, all of them will scale to the clock of the slowest card, I think.

Im not sure how the SLI frame rendering algorithm works so yeah. Just test it out.

I have seen instances of people having different clocks on their GPUs though I'm not sure how it works when frames are actually being rendered.

As far as I know you can OC both you just have to make sure that the cards are OC-ed by the same amount

You can have two cards running at different speeds in SLI however you SLI config will "technically" run at the one clocked lower. I've had SLI configs with 3 cards all at different clock speeds, didn't really make a difference.
