Claymore - do you think further optimizations for fiji chips are possible? Memory controller usage seems to be sitting pretty low, and I get the feeling after playing with intensities that there's more room left for optimization.

It seems a higher ethi allows for increased decred hashrate without ethash loss. I am now pushing ~30MH/s ethash and 1650MH/s decred with ethi 20 and dcri 110.  With ethi 16, dcri can't go that high without losing a chunk of ethash.  Compare that to 30MH and under 1000MH/s decred max with lower ethi.
