SLI - 2 Different Cards

[Dirk Diggler]

I bought a second 980ti in the MM to go SLI. I swore I wouldn't go back SLI, but with current second hand prices I couldn't resist and am happy to put up with the grief (hopefully not too much of it) while I wait for the next actual high end card to come out.

I'm pairing my Classified up with a card that may not keep up with it's clock speed, a MSI 980TI Armor 2X:

I'm not expecting the MSI clock speeds to keep up as I say, and I'm thinking maybe the cooler will be a bit weak too. I'll be SLI on air and was considering whether I should leave the Classy as it is (1418/stock) and also leave the MSI as it is, which will be lower clock.

Would the imbalance in clock speed make much difference? If the MSI is cooking a wee bit I may even downclock it a little bit.

Anyone any thoughts/experience with a similar set up?

im pretty sure, both cards run at the lowest speed of either card. So mismatching isnt a problem, as long as they are both the same type.

I take it you mean same type as in 980ti?

Would anyone with sli on air be prepared to do a wee benchmark test? Any game at current settings and then with say - 200 on the core? I'd be interested in what the cost was in terms of score and the benefit in terms of heat reduced?

If I recall correctly the boast clocks of my SLI GTX 670's matched. Unfortunately I don't have both cards now to check.

But you be ok with different versions of the same card, my MSI and Gigabyte ran fine together.

Yea, if youre planning to SLI 980ti's, then they both need to be 980ti's. You cant SLI a 980ti with a 980 for example. I guess 'type' isnt exactly the right word.
