GIGABYTE Ultra Durable
Motherboards for Ultimate Mining
What is Bitcoin?
Bitcoin is a type of digital currency in P2P form, where transactions take place between users directly. These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain. The peer-to-peer transfer represents a decentralized payment system.

Unlike most currencies, the issue of bitcoin doesn’t rely on certain monetary authorities. Instead, it’s based on a specific algorithm and created through a large amount of calculation. The main difference between bitcoin and other virtual currencies is its limited overall quantity, resulting in great scarcity. There would only ever be 21 million bitcoins in total.

Besides being created as a reward for mining, bitcoin can be exchanged for other currencies, products, and services in legal or black markets.

Now the demand for mining machines is not only for bitcoins, but also a variety of other virtual currencies such as litecoin, ethereum, peercoin and a few others.
Quality Components Make Quality Motherboards
GIGABYTE Patented DualBIOS™
GIGABYTE Ultra Durable™ motherboards feature GIGABYTE DualBIOS™, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS™ means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', protecting users from BIOS failure due to virus, hardware malfunction, improper OC settings or power failure during the update process.
Long Lifespan Solid Capacitors
GIGABYTE motherboards integrate the absolute best quality solid state capacitors that are rated to perform at maximum efficiency for extended periods, even in extreme performance configurations. This provides peace of mind for end users who want to push their system hard, yet demand absolute reliability and stability, with ultra-low ESR no matter how high the CPU loading.




Start Sulfurization Protection

Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.

How to Set Up A
Mining Machine?
  • Doing hash calculation requires multiple graphics cards.
  • Although hash calculation highly rely on GPU processing power,
    for PCIe, the bandwidth of PCIe x1 lane is sufficient for mining calculations.


Users can extend PCIe slot via a PCIe riser card using PCIe M.2 slot.
This allows for a more flexible installation of GPUs in mining frame chassis for improved airflow.


PCIe x1 to PCIe x16 Cable
The dual PCIe power connectors provide a more stable PCIe power supply. If the Windows system fails to recognize multiple graphics cards, please change the PCIe speed (BIOS Settings) settings to “GEN 2”.


How to Set OS for Mining?
  1. Please note that before installing the OS, the LAN cable should be removed and the BIOS settings should have been completed.
  2. When installing the OS, Windows 10 version 1703 64-bit or higher is recommended.
  3. Go to Settings / System / Power & Sleep. In the Screen section, select “Never” turn off the screen, and for the Sleep section, choose “Never” as well to prevent the system from going to sleep during mining.
  4. After installing Windows 10, please turn off windows update. Only after windows update is shut down can the LAN wire be plugged back in.
  5. Go to Control Panel / System and Security / Power Options and select "Choose what the power buttons do". Click "Change settings that are currently unavailable" and disable the "turn on fast startup (recommended)" function.
  6. Install various chipset drivers for your motherboard.
  7. It is recommended to add only one graphics card at a time. Each time a graphics card is attached to the motherboards, install the driver to make sure it runs smoothly, then go on with the next one until all graphics cards are added.
# The system requires over 16G of virtual memory when 8 or more graphics cards are attached. Users need to manually adjust the size of virtual memory following these steps: Right click “This PC” and go to Properties/ Advanced, then select the “Settings” options in Performance section. Find “Virtual memory” under “Advanced” section and click “Change”.
How to Set BIOS for Mining ?
< BIOS Version F21 >
