Here we adopt 12 graphics cards and TB250-BTC PRO for this crypto mining hardware installation.

Hardware Requirement
  • Total 12 graphics cards
    AMD graphics cards support a maximum of 12 cards.(driver 17.11.1 version later)
    NVIDIA graphics cards only support a maximum of 8 cards due to driver limitation.
  • Memory: 16GB
  • Power supply: 1200W x2 (depend on the power consumption of graphics cards)
OS / Software Requirement
BIOS setting & Driver installation

Don't connect any graphics card to motherboard before finishing OS installation; just install OS with onboard graphics.

Note: Or install OS with only one graphics card connected to PCI-Ex16 slot, other steps are same as below.


Please update BIOS to B25DF710.BSS or after version where mining mode default is enable.
The BIOS Download Page as


Follow Windows instruction to finish OS installation.


Turn off the computer; install all graphics cards properly (please refer to the hardware installation page).


Change video output to the graphics card connected to PCI-Ex16 slot (This step is for installing OS with onboard graphics only).


Power on and install motherboard drivers and graphics card drivers.


Reboot and start to mine.

Hardware Installation
Step 1.

Please install every graphics card into the riser cards (as the picture below) respectivelly.

**The power cable for riser card and power cable for graphics card must come from same power supply uint.

**The USB cable of riser card must not be connected to any the USB port on motherboard.

Step 2.

Connect 8-pin power connector and 24-pin power connector to the power supply-1.

Connect 4-pin 12V AUXPWR 1 and 4-pin 12V AUXPWR 2 to the power supply-1. Also, connect SATA cable to HDD or SSD.

* These two AUX power connectors are BIOSTAR unique design of graphics card power enhancement.

Step 3.

Connect PCI-Ex16 riser cards with graphics cards installed properly to the PCI-Ex1 riser cards installed on motherboard by USB3.0 cables.

Connect power cables to graphics card and PCI-Ex16 riser card. 6 graphics cards powered by power supply 1, another 6 graphics cards powered by power supply 2.

Step 4.

Follow the instruction below to establish a short circuit between No. 15 pin and No.16 pin on the 24-pin power connector of Power Supply 2.

Step 5.

And the last step, turn on the power supply.

**The instruction is designed with 6 Nvidia GTX1060 and 6 AMD RX470 graphics cards as example.

Step 6.

Get ready to make money with BIOSTAR Crypto Mining Motherboard!

To keep the mining rig operating stably, please install the system in an environment where there is a sufficient volume of air available to cool your rig. To top it off, you can use two industrial fans to make the air convection much efficient.

*The graphics cards connected to PCI-Ex16 slot must be powered by power supply 1.

*Each power cable from power supply is limited to be connected to 2 graphics cards or 2 PCI-Ex16 riser cards.

Blockchain Compute Optimization for AMD RX series GPU

Use following setting to set optimized Blockchain compute performance inside the driver:

  1. Open Radeon settings by double clicking the red Radeon logo (Windows main screen lower right corner)
  2. Go to “Gaming” -> “Global Settings”
  3. Choose your GPU for mining 
  4. Switch “GPU Workload” from ”Graphics” to “Compute” and confirm by “Yes”.
  5. Radeon setting application will restart
  6. Start your miner
