Don't want to hijack this thread, but I had some folks asking for a modified pool according to the requirements for this miner, I just reconfigured/adapted the Stratum ports of
https://dash.suprnova.cc to meet the requirements of the miner and also added some static Diff Ports:
Port : Diff
"9994": 1
"9995": VarDiff
"9996": 2
"9997": 4
"9998": 8
"10000": 16
"9993": 32
"9992": 64
"9991": 128
"9990": 256
I doubt just use the VarDiff port, but i'd assume fixed diff of 32 or 64, or maybe even 128 should work fine.
Let me know if you see any improvement over all.
Thanks
