I'm mining the new algorithm without problems

I'm getting lower hash rate than before but I'm enjoying:
Before:- Cryptonight with Sgminer-GM -> 3000 h/s.
- Cryptonight with XMR-Stak -> 2550 h/s.
Now:- Cryptonight-heavy with XMR-Stak -> 2250 h/s.
I'm using 5 AMD R9 380.
Do you know if SImpleminingOS is ready for this coin? If it is, can you help me with config?
