Hi, I've have to honest on this one - I’ve tried ver 06, unfortunately so far no improvement at all...I’m just not sure if it really worth it. currently, the ver.b6 doesn’t give me any of the advertising hash rate. (10-15%  -realy???/are you sure?)
To be clear, a have an excellent performed on my  46 rigs of Sapphire AMD Radeon  GPU RX 480 8gb Samsung, each  easily giving 8930-8950 h/s, founded best  running on 33ver.b2, /////  and  running  by very  similar hashrate 8800--0890 on ver, 0.3.b4 on my  17 rigs 8x580  8Gb powered by Hynix memory, its sems more  stable on this version .  So if you going  with Polaris on 8Gb Samsung – the 0.33.b2 its the best version for you, on the Hynix Memory-  its hard to beat ver b4. JUST IGNORE THE VER B05 / B06 AT ALL COST!!!!

Yeah, same problem with cryptopia's wallet today, sent coins six hours ago and still nothing on cryptopia's balance, no records on deposit history. So frustrating…, hopefully another exchange will be in place soon.

Just checked the new version, and same issue there: miner shuts down after switching from mining devfee (cryptonite on nicehash). This happen on all my rigs. It only works if I leave a few GPU’s unchecked on main screen. On my tests it only works on up to 5-GPU’s. 6,7,8-GPU configuration doesn’t works.
Tested on 5 rigs with AMD RX480/RX580/RX570 using blockchain beta drivers, and crimson 17.7.2 drivers, but same miner behavior, it just limit you to up to 5-GPUs on Cryptonite algo. Seems that Ethereum on Nicehash pool has no this issue – all GPU’s are usable
