Got my 2nd batch 3xZ9mini's from Bitmain since few days ago.
What have I done:
- flashing the overclockable firmware (Sat May 26 20:42:30 CST 2018)
- set the frequency to 650 (after many failure attempts starting with 700 and goes down)
- set the fan speed to 95%
- changed the dhcp to static (ip: 192.168.1.10x, mask: 255.255.255.0, gw: 192.168.1.1, dns1: 192.168.1.1) for each unit
- set the min payout for not flooding the blockchain to: 0.3 ZEC, 6 ZCL and 2 ZEN
- added the following pools:
- miningpoolhub (with their awesome auto-switch for profitability): europe.equihash-hub.miningpoolhub.com:17023
- nanopool: zec-eu1.nanopool.org:6666
- antpool (not a good idea as the latency with their servers is too high, as a results there will be more rejected shares): stratum-zec.antpool.com:8899
- a hashrate between 13-15 ksol (14 ksol average)
- PCB temperature: 47, 55, 50 (celsius degrees)
- CHIP temperature: 60, 69 ,68 (celsius degrees)
- HW errors: 0
- rejected shares: below one per hour
- my first payout from nanopool
This is my setup. Until now, it's running well.
Who's helped me? You, guys. Thanks!
Happy mining!
