This could be the last version, because there seems no more room for big jumps. I thought I could remove some more additions, but the OpenCL compiler does a better job than I Cheesy

. This version is faster than all previous kernels (uses the least ALU OPs for 69XX and 58XX). Should also work with SDK 2.1. If it throws an error with 2.1, please post here and include the error message!

Thanks to all donators and your feedback!

Awesome work. Btw, could you explain why Vals[2] = C1; is needed in the beginning when it is reassigned in round 5? I know removing this line breaks the hashing but I'm not seeing why since it isn't used prior to round 5.

Various functions before the reassignment use Vals[2] search the kernel for Vals[ and you will see them. I tried to remove that assignment, but as you discovered, it is needed there Cheesy

I only searched for Vals[2] so did not see the % XD

Very small increase for me on this one 278->278.5. Interestingly a lower memory clock on my 6870 actually has a detrimental effect. Downclocking from 1050->800 reduces hash rate b 0.5MH/s. I can't clock it any lower so don't know if 300 will be better or not.
