Very nice numbers, I guess I share mine as well now, they are for 4 x R9 290:

I think it still has some bugs, the pool rejects my shares when diff is low, but after target switches to lower value everything works fine. Also not sure if these numbers are correct, the pool shows 13-14 MH/s.
I'm going to open source this miner when your is out, good luck with more optimizations. Power usage on R9 290 when mining this is about 100W/card.
Great effort there too. We see stratum issues as well - need to start the miner a couple of times before it starts smoothly
We have some great optimization ideas in mind, due to the way the coin was designed. Today is optimization day.
Factor 2-3 more speed should be easy to accomplish for us.
