If this is at idle it would seem that the second card is not dropping into 2D mode. Have you tried swapping the cards around?
Well, here's the story. I just changed them around. But the Evga was giving the same clock speeds in the first setup as well.
I initially had the MSI as GPU1 in the first PICE slot, and EVGA as GPU2 in PCIE slot 2. I was getting some high temps on the MSI, so I wanted to move the second card to the third PCIE slot. The EVGA wouldn't fit in the third slot, because of some connections on the MB. But the MSI fits there.
All that said, the clock speeds never changed for the EVGA.
