Different clock speeds

post #1 of 5
Thread Starter 
What happens when we put two of the same cards together in SLI but they're clocked differently?

For example, the ASUS GTX 580 clocked at 782MHz and the MSI Twin Frozr II GTX 580 clocked at 800MHz in SLI.

Will there be any issues that may arise when these two cards (although same GPU) are put together in SLI?

What would you recommend?

Under/Overclock the cards so they match up.

I believe the higher card will clock down to match the lower one.

E: I don't think there's any issues with it, but you could always just manually downclock the higher one to make sure.

It doesn't matter, they'll work fine together. I would use Afterburner to OC both of them to the highest stable clocks that both of them will do (iow make them match each other, but @ higher clocks than either of them presently is)

No need to do it manually. It's automatic with SLI enabled. Though, I'd definitely say OC the Asus up to 800mhz. You don't need to really push those cards, a pair of 580s will blow through anything at stock, and then you can do a full overclock to them down the road and it'll feel like you got a performance boost.
