Hi, at this moment i'm using the 3.1.1 Cgminer version, but what is the best for this GPU? ( ati 6870 )

I use 3.7.2 and get ~ 300 kh/s from both my 6870 cards. (I 18)

mmm ok but with I 13 and cgminer 3.1.1 i have 210kh/s about, while with 3.7.2 i have 167 kh/s

With I13 i also have 200 kh. You need to use I18 for 300 kh/s.
