Hehe I guess so

Maybe it will change with the new SDK 2.5, so we can squeeze out a little more Hashes

Yes, I look forward to when that is released. As far as I can tell there's a early version out but it's only usable on Windows.
By the way, how are you using phatk? Are you driving it through phoenix? If so be aware that, by default, the readout is an average of the last 10 rates and this can be disabled with the flag '-a 1'. I find the moving average is only useful if your MH/s is leaping around by more than 1 MH/s say which shouldn't be the case here.
