Okay, I reran KMark, I used the 720P mode but it does it for all modes. I also noticed that the clock on my first card was still in the low power state. I didn't notice it before, so it seems that crossfire isn't wroking properly, which makes me think even more that it may be a driver issue. I have cata 12.2 previews installed, and not the official release drivers because they were causing me other issues; and I have CAP 12.2 v 1 installled. EDIT
: Never mind, it shows the right clocks in 1080p mode, its just the 720p that doesn't show the right clocks. Regardless though, I have the same flickering issue no matter the settings I use.
