1 Overview
The S5 server is Bitmain’s 5th generation of Bitcoin mining rig and uses the state-of-the-art
BM1384 chip powered by ultra-low power 28nm technology. S5’s are tested and configured
prior to shipping to make it easier for customers to set up.
Please note:
1. You must prepare your own ATX Power Supply

Notes: Input voltage should not be less than 12.00V, since it is based on serial power solution
and there is no DC/DC inside the server. Higher input voltage will cause higher mining efficiency.

3 Power Supply
Each S5 server has four PCI-e connectors for +12V/15A DC STABLE input and all four are
required. Do not connect more than one PSU to the same hashing board to prevent
possible damage and instability. See below screenshot for the CORRECT and INCORRECT
connection of the PCI-E connectors:
Correct connection:
Incorrect connection:

Password- This is the password for your selected worker.
Comment:
4.1.1 The S5 server can be set up with three mining pools, with decreasing priority from the
first pool (pool 1) to the third pool (pool 3). The pools with low priority will only be used if all
higher priority pools have gone offline.
4.1.2 When ‘Beeper ringing’ is checked, a beeper will ring when the server stops mining,
otherwise it won’t ring even if the server stopsmining.
4.1.3 When ‘Stop running when temperature is over 80℃’is checked, the server will stop mining
when the temperature exceeds 80℃ to protect the server. If it’s unchecked, the server will still
mine even in high temperature.
Click ‘Save & Apply’ to save and restart server.
5.2 FrequencyModification
You are able to modify the frequency value through Advanced Settings marked below. The
default frequency for the S5 server is 350M.
5.3 Server Link Connection
