UMC Installation Instructions
Pop the top cover on your S19 miner, to expose the control board. Then disconnect all the cables on the old control board.
-
Remove the faceplate and slide out the old control Board, slide in the new UMC control board & reinstall the faceplate. If your old faceplate does not fit correctly, you can buy a UMC faceplate here.
- Plug in all the necessary cables as shown (3 hashboard cables, 4x fan cables, voltage regulating cable, 6-pin power cable & Ethernet cable)
- Use J2, J3, J4 hashboard connectors. Do NOT use J1 (The connectors are labeled on the control board.
- Power on the miner and locate IP address.
- IP address can be found using a free IP scanner tool like Advanced IP Scanner or Angry IP. Device name for UMC control board will start with ‘cminer’. Note that IP report button on UMC will not report IP using Bitmain’s IP reporter tool.
- IP address can also be found using ePIC Dashboard fleet management tool. Default password for both web UI and ePIC Dashboard are ‘letmein’.
-

This is commonly caused because of a hashboard connection to J1 connector. Refer to Installation Instructions section above to remedy this issue.
Firmware Presets aren’t fully configured for various S19 models. Please use perpetual tuning based hashrate targeting or manually setting volt & freq.
The spikes are artifacts of realtime hashrate tracking on the chart. This is normal and OK to ignore.
Chip performance/efficiency above 97% is green, 91-97% is yellow, 91% and below is red
Firmware updates are released by ePIC periodically and can be downloaded here
ePIC UMC compatibility is not dependent on PSU version.
ePIC UMC has been tested on thousands of ASIC miners over several months and there are both temperature & connectivity based guard- rails in the firmware. However overclocking always comes with additional risk to your hardware and you should proceed with caution.
No fan spoofers are needed, you can run with 1,2,3,4 or no fans.
Yes, hardware modifications and running custom firmware typically voids Bitmain warranty. This is also the case with other firmware like BraiinsOS+, Vnish, LuxOS etc.
