7970 XFire Issue

I recently bought another 7970 and when I enable Crossfire with the reference model I get really bad flickering, like the old analogue TV's. It only happens when I enable Crossfire.

I recently bought another 7970 and when I enable Crossfire with the reference model I get really bad flickering, like the old analogue TV's. It only happens when I enable Crossfire. The single GPU is fine. The other card is an non reference PCB and Cooler, I thought it would be a reference model but it isn't. I'm also using the latest drivers, 13.1. An help appreciated.

I've disabled GPU1 on my board and the second one works fine. This is, as far as I can tell, a purely Crossfire issue.

EDIT 1) Have changed the Crossfire Bridge and no improvement, also the clocks are the same, so I don't think that's the issue either

EDIT 2) FIXED. FIXED. FIXED. I swapped the 2 cards slots and used and HDMI to DVI adapter. No problems anymore.
