I always ran both off the first when I had SLI, but to be honest I don't think it makes any difference at all.

Nvidia say you should run both of the main card.

No idea if it is just my setup or what, but when I ran two displays off of the top card, the top cards temperature would rise by at least 10C. I have since run one display off each to balance the temperature. biggrin.gif

The top card is getting hot because the heat from the bottom card rises into it. Plugging two displays into the top card does NOT make it work harder.

Right, so when I move the second display to the bottom card and watch the MSI afterburner graph drop from 91c to 80c for the top GPU in an identical gaming session it's a lie. (GPU usage on both cards @ 95%+)

I'm just going off what Nvidia say, I don't have any personal experience because I've never run an SLI setup. They say whichever ports you use it shouldn't affect performance tongue.gif

It blows me away too. Not sure if the card is defective or what. Never had any other card do this. Overclocked or not, minimum 10C difference when the monitor setup changes. Anyways. on topic... Plug them both into the top card if you can. thumb.gif
