How do I get ethereum miner to recognize 2 cards on the same computer ?... it only mines one of 2 cards .nvidia 980ti at 22 mh/s.
It should have  -d 0,1 but doesn't work..like cuda should.
Thx

EDIT: This my bat file that doesn't work      

ethminer.exe  --farm-recheck 3000  -o http://eth-us.suprnova.cc:3001/razorsedge.eth1/22

On the donation bat file I get 1 card 980ti that gives 22 mh/s...but this bat file above doesn't work.
Please help.
thx
