Mining
A rig mines while it is powered, online and pointed at a NAS share for its payout logs. Earnings build up in the rig's VAULT. FLUSH moves the coins into your crypto wallet, and nothing is sold until you sell. Or unlock AUTO-FLUSH with Chips and every vault flushes itself.
Each rig mines the coin you choose: LBC, RACK, DNET, DBL, UPT or GWT. All six trade on one market shared by every player. Mining is slow money: 100 MH/s earns about $30 an hour at a coin's base price on the balanced profile.
Every part moves the number
- Hash boards make the MH/s: H1 50, H2 95, H3 165, H4 260.
- The processor feeds the boards: +4% per compute unit, up to +60%.
- Memory buffers the work: +1% per GB, up to +40%.
A build can't draw more than its PSUs supply. The workbench refuses a board the PSU can't carry.
Heat
A rig heats with what is installed and how hard it runs: eco, balanced or turbo. Past its safe temperature it throttles, down to a quarter speed, and further past it shuts down. Better fans are the answer. The heat vents on the face glow ember as it warms and the screen flashes THROTTLE.
Terminal: rig, rig <dev> coin dnet, rig <dev> profile eco, rig <dev> flush.
Filling the frame
It ships half full. Four more board slots, a second processor socket, two memory slots, a third PSU and two fan slots are free. Big boards need the 1600 W units: eight H4 boards need three of them. Eight boards share one airflow path, so the frame heats faster than the 1U rig. The 120 mm HP and Turbo fans are the counter.
It draws hundreds of watts. Feed it from a 1U PDU 1500, and give its PSUs feeds from two chains.
