Green and magenta static on ONE Mac Pro.

Is it possible that when you plug the Kona 3 into the same “crossfire” bus as the video card (which is normal) it readjusts the (Memory-) timing to the video card or Kona 3 card and there`s some adjustment of it`s timing with a name like “video 2T” or “video UM” that should be adjusted in the bios or motherboard jumpers? Had you tried my power supply fade guess?

I’m experiencing the same problem unfortunately. Did you find a cause or solution?

Really confused here guys, any insight would be appreciated.

Aidan, to repeat my answer,
if the voltages coming out of your power supply feeding the insides of your computer are sagging, the oscillators inside the Kona card could get forced to go out of frequency tolerance whereupon you see exactly what`s described. Grab a fresh power supply and a voltmeter and do a little testing. I had no luck going to TekServe in N.Y.C. The cause was a Manager who had an ever- changing story.
