I had the same issue. My problem was lack of power.
Try lowering the intensity and then raise it slowly.
Topic: CGminer screen is blank when I run two cards, but works with just one. (Read 814 times)

I just recently got two R9 290x cards. I installed one first and got it working with CGminer 3.7.2 and it was doing over 900kHs, so then after I knew all that was working correctly I installed the 2nd card and tried it again. When I try to run it with both cards the command promt window is blank after I start it running and doesn't show the info like before or the options to change settings.
I did find if I put in the "- T" option then it does at least show me most of the information that it did before, but instead all the info is at the bottom of the cmd promt window and it doesn't stay, it comes and goes as shares are being accepted etc.
Is there some way to get it to display the way it did before? I prefer that for tweaking the settings on the cards and being able to see real time results.
I am running Win7 and installed the factory driver CD for the cards and then also installed SDK 2.7.
