Increasing MD5 GPU Utilization?

[CTu2y]

Had to leave earlier but now working on this large set again.

Updated the hashset as you show above and used mode 20 for md5($salt.$pass)
It did double my speed on the large hashset which is good but still 1/4 the speed possible.

will try and run some tests to see how many I can do at once with a high 4000 MH/s speed and then split the hashset into this size pieces to optimize my time.
