I have an AMD zcash miner, win-only, stratum-only.

It does about 22H/s on a 390X now. I might release it but I'm afraid it needs more speed.

Genoil-zec-miner-0.3.2 not working with R9 Nano on Win7 64bit. I tried with 15.12 and 16.9.2.

You can use the 0.42, 0.5 or 0.6 to mining with the 16.9.2. But the speed is about 28H/s at stock.

Before Genoil create a faster miner, it is better to use the Claymore miner eventhough it has 2.5% fee.
