R9 290 cycles fix not working?

Hey, sorry if this is the wrong spot…

Attempting the cmd mod to allow use of an AMD card in cycles… Causes blender to crash.

Ohh and sorry for the screencap, 3440x1440 is odd to cap.

Spec: 290tri-x
i5 3570k
8gb ram
win7 64bit
Latest drivers, both omega and the beta seem to produce the same result. Attempted several versions of blender too.
