R4 exact manual profile
The manufacturer manual specifies an ideal 8.6 TH/s +/-5% at a 600 MHz default clock. Estimated wall power is 845 W with a +9% allowance when using an APW3 at 93% efficiency and 25 C ambient. The manual states estimated wall efficiency as 0.1 J/GH with +9% allowance. These are conditional manufacturer estimates, not universal measurements.
External power-supply boundary
The miner requires 11.6-13.0 V DC across seven PSU connectors. Current manufacturer compatibility guidance lists APW3-series, APW5 and APW7 supplies. The miner does not accept facility AC directly; facility voltage, current, plug and branch-circuit requirements come from the exact selected PSU. Use one correctly sized PSU per miner, ground the system, verify polarity, and connect hashboards before the control board.
Physical, acoustic and lifecycle facts
Dimensions are 515 x 100 x 222 mm, net weight is 5 kg, operating ambient is 0-40 C, and the manual rates 52 dB at 35 C ambient. Ethernet is required. R4 reached manufacturer end of service on May 9, 2020, so current firmware or repair availability must not be assumed.
Firmware identity
The manufacturer later identifies an 8.7T-600M fixed-frequency R4 version. Treat that as a distinct version note, not permission to overwrite the manual 8.6 TH/s rated profile or cross-flash firmware. Select firmware by exact model, frequency/version and physical board identity.
