1Overview
The R4 server with 8.6th/s is Bitmin’s newest iteration. The R4 server uses the fully custom
made, state of the art BM1387 chip powered by ultra-low power 16nm technology. The R4 is
tested and configured prior to shipping to make your setup as easy and seamless as possible.
Please note:
1. You must prepare your own ATX Power Supply

Notes: All the 3 PCIE connectors are required on each hash board and there is no DC/DC inside
the server. Higher input voltage will cause higher mining efficiency.

3Power Supply
Each R4 Server has 6 PCI-e connectors for +12V/15A DC STABLE input on hash boards and
1 PCI-e connector on the controller, all the 7 PCI-e connectors are required. Do not connect more
than one PSU to the same hash board to prevent possible damage and instability. After
connecting all the hash boards and the controller to PSU and the wire cable to the ETHERNET
port, you can start the server. See the screen shot below for the CORRECT and
INCORRECT connection of the PCI-E connectors:
Correct connection:
Incorrect connection:

4Connect to Server
Step 1. The default DHCP network protocol distributes IP addresses automatically. Please
download IPReporter.zip (only supported by Windows) , then please follow the below steps to
find out the IP of the server.
1. Extract the file and double click ‘IPReporter.exe’.
The ‘Shelf, Step, Position’ options are suitable for farm servers to mark the location of
the servers. For home servers, it can be left as default.
Then click ‘Start’.
2. Press the IP Reporter button on the controller board for about 5 seconds and you’ll hear
a beep sound:

3. Check your PC, you’ll see the IP address showing in the pop-up window.
Step 2. Enter the IP address provided into your WEB browser and proceed to login using ‘root’ for
both the username and password.
In the ‘Network’ section, you can assign a ‘Static’ IP address if you like. Click ‘Save & Apply’ after
modifying it.

5Server Configuration
5.1 General Settings
You can configure your server through ‘ Configuration->General Settings’.
Pool URL- Enter the URL of your desired pool in this column.
Worker- This is your worker ID on the selected pool.
Password- This is the password for your selected worker.
Comment:
5.1.1 The R4 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.
5.1.2 When ‘Stop running when temperature is over 80℃’ is checked, the server will stop
mining when the temperature(PCB) exceeds 90℃ to protect the server. If it is unchecked, the
server will still mine even at high temperatures. Note that while the interface says 80℃ the PCB
temperature will actually go to 90℃ before the machine stops mining.
5.1.3 When “Customize the fan speed percentage” is checked, the fan speed can be controlled by
the user. If it is unchecked, the fan speed will depend on the temperature of the hash boards.
Click ‘Save & Apply’ to save and restart server.
Kindly reminder: Please set the fan speed above 80% to keep the temp(PCB) below 90 degrees
and the temp(chip) below 115 degrees.

5.2 Frequency Modification
You are able to modify the frequency value through ‘ Configuration->Advanced Settings’. The
default frequency for the R4 server is 600M.
6Server Status
You can check the operating status of your server on the page below.
ASIC#: Number of chips detected in the chain
Frequency: ASIC frequency setting
GH/S(RT): Hash rate of each hash board
Temp(PCB): Temperature of the hash board, centigrade
Temp(Chip): Temperature of the chips on the hash board, centigrade
ASIC status: ‘o’ denotes OK, ‘x’ denotes error ‘-‘ denotes dead.

7System Configuration and status
7.1 System Upgrading
You can upgrade the server’s firmware on the ‘System > Upgrade’ page.
‘Keep setting’ is chosen by default and should be enabled if you want to keep your current
settings. You should deselect this option if you are trying to return the server to default settings.
Click ‘Browse’ button to choose upgrade file. Select the upgrade and click the ’Flash image’ button.
The interface will display if the firmware can be upgraded and download the software. During
the upgrade process, you need to wait patiently, and must keep power on, otherwise, the
server can only be fixed with returned to factory. You will see below screenshot after
upgrading successfully.
Clicking the ‘Reboot’ button will restart the server so it can load the new software. Clicking
‘Go Back’ will keep the server mining before switching to the new software when it is restarted
next time or power cycled.

7.3 Software Version
You can check which version of the software you are currently running on the ‘System >
Overview’page. ‘File System version’displays the date of the firmware your server use. In the
example below, the server is using 20160527 firmware.
7.4 Restore Initial Setting
There is a ‘Reset’ button on the right hand side of the ETH port, next to the green and red LED
light. Power on server and let it run for 5 minutes, then press and hold the reset button for 10
seconds in order to restore to the default settings and reboot. The red LED will flash once every
15 seconds automatically if the reset is operated successfully.
