Interesting. I got AMD 14.6beta running tonight on my Windows 7 (64-bit) rig. Also added these new kernels. Boosted my four 290X's to 5.4 Mhash each (!) from around 4.0 before. That's also after I scaled back engine speed from 1050 to 1010 because of several sick GPU's and restarts within an hour. Seems more stable now but we'll see. I'm running with xintensity of 360 (372 would equal Intensity 20, but 360 is faster for whatever reason). Oh, and I had to change the Lookup Gap in the config file from 2 to 4 to get it to run.
