290x/win7 x64/13.12catbefore(2%-version): -w 256 -tc 20481 -g 1 -I 21 -----> 3.85mhs
after(free-version): -w 256 -tc 20481 -g 2 -I 15 ----->2.75mhs
no way for -g 1/-w64/-w128-parameters - it`s always 2.6mhs or less
PS What are the optimal settings for 290x/290? I still think that the lack off "-I" (crash of miner when "-I" is above 15) is the main issue in reaching more mhs.

Same problem for a 290/W7/cat14.4
2% version : I 15-> 2800 Mhs, I 19 ->3900 Mhs
free version: I 15-> 3050 Mhs, crashes for I > 15
On BAMT 1.3, I only get 2850 Mhs for I 15 and crashes for I > 15.
Edit : 3080 Mhs with TC 8192 and gpu-threads 2
