Asus P106-100 6 GB, 4 cards, mems +850/900/900/950, power limit 65% -> 104 MH/s in claymore 9.7, 375 W from the wall. I checked ethminer 0.11.0 but saw no improvement, while reported hashrate was missing on ethermine.org, so I'm staying with claymore.
Interesting thing is that the card has Display Port vid output, but you have to unscrew the bracket to get it

I don't have anything with Display Port to test if it works.
