To do this, flash the BIOS of each and every GPU with AtiFlash.

Once the process is done, reboot your computer.

#9 Download Mining Software

On reboot, check once more if the system still detects all the cards.

Login and download your preferred mining software and install. Just to name a few: BFGminer, CGminer, NiceHash.

The next thing is to choose a pool and set up your pool’s credentials.

Choosing a pool is essential if you are to realize a good ROI because if you choose to solo mine, the returns will be too little and far apart.

You should now go ahead and set up the .BAT file to automatically start the mining software of your choice on system startup.

Go to Windows – Start – Programs – Startup and have a .BAT file shortcut created.

With the SSD in place, the will be the set up: Run – Services – superfetch (disable).

You should then disable all updates and make sure you cancel any scheduled tasks.

Download the latest version of video card drivers and then do an installation.

Once done with the installation, reboot your computer.

On booting up, go to Device Manager to check and verify that the system has detected all the GPUs.

#8 GPU BIOS set up

Before you proceed, it is also prudent to make a backup of all the files. For the RX series, I recommend you go for Polaris Bios Editor.

Next, we want to set up our GPU by doing a BIOS flash.

  • Profitable when done properly.
  • Cons

    • Quite expensive.

    What to consider when building a mining rig?

    Consider the following when building your own mining rig.

    #1 Hash rate

    Hash rate refers to the total number of calculations that the mining hardware can handle every second when the mining process is on.

    We measure hash rates in terms of their megahashes (MH/s), gigahashes (GH/s), and terahashes (TH/s) per second.

    In mining, the higher your hash rate, the more it is likely that you may end up successful in getting a transaction secured and verified.

    This means a higher chance of getting an ROI.

    #2 Energy consumption

    Cryptocurrency mining consumes huge amounts of power and therefore, the cost of electricity is always higher. Beware of how much that given to set up will consume vs.

    In this case, attach one card to the motherboard and the other 4 to the Risers.

    Therefore, if you have 2 Molex cables, you should be able to connect all the other four cards.

    #5 Booting up

    First, you must have an OS system of your choice on a USB drive.

    When booting up for the first time, have your computer monitor connected to the motherboard. The connection should be either to the motherboard’s Graphics output or essentially to GPU.

    Next, plug the PSU into the wall socket before you connect the Ethernet cable. You should then boot up the computer and go to BIOS.

    To “feed” such a device, you will need to choose a high-quality power supply that can withstand heavy loads and support the system without interruptions.

    What is the best power supply for mining? Miners usually use one of these solutions:

    • One ATX format power supply unit (Advanced Technology Extended) – For a small mining farm, power from 1000 watts will be enough. It is convenient to connect to a unit. Pay attention to the number of slots for video cards – the power unit of the mining rig will depend on this.
    • Several synchronized power supplies with a special cable. They differ from the previous version in that they give more power allowing you to assemble a larger rig.
    • Server power supply – It has a large output power and internal resource, but requires soldering for installation in the farm.

    Both Nvidia and AMD graphics chips have their advantages and disadvantages. But the main difference between them is the efficiency in mining. Depending on the coin, miners select exactly those video cards that give more power and consume less electricity on a certain algorithm.
    You can learn more about this in our article regarding the best GPUs for mining.

    The main pros and cons of the cards of the two manufacturers can be described as follows:

    • Nvidia is easier to configure, fewer problems with cooling, but the power consumption is slightly higher.
    • AMD is more difficult to configure and maintain, there are nuances in cooling, but more energy efficient.

    The best graphics cards currently are the RX 400-500 series cards from AMD and GTX 1060 (6 gigabytes) / 1070/1080 (Ti) from Nvidia.

    In addition, 6-pin risers have three wires for each power pole, which provides a more balanced load on the connectors.

  • A slightly worse riser with a 4-pin molex power connector, which consists of two ground wires and one 12 volt wire.
  • The worst riser options are risers with a SATA power connector because they have thin pins. Such risers will eventually lead to problems with mining because of burnout of contacts at the connection point.
  • Power Supply Unit

    A mining rig (especially if several powerful video cards are involved in it at once) is a very energy-consuming thing.

    It is recommended to use a power supply unit with a capacity of at least 750 W depending on the needs (GreenVision, Chieftec, Aerocool).

  • Processor – (AMD, Intel).
  • Video Cards – The optimal number of cards for one farm is 4-6 units, with a speed of at least 400 h/s (Nvidia, AMD, Sapphire, Gigabyte, Asus).
  • RAM – For efficient installation, you will need at least 4 GB of RAM.
  • PCIe Risers – vertical mount cables help connect graphics cards to the motherboard (Atcom, HQ Tech, Cablexpert). The hard drive, in fact, is only needed to install the mining farm software (60 to 120 GB is enough).
  • A fan will be needed for additional cooling (NSI, Zotac Polit, Gigabyte).
  • The Linux operating system is considered the best operating system for mining.
  • AMD atikmdag Patcher can help. Click on ‘Yes,’ and after reboot, the problem is solved!

    Watchdog: Connect Watchdog to the Reset and Power connections on your motherboard, so that the timer can reboot or turn on/off your rig. The two images below show the same thing, the only thing that changes is the coloring of wires.

    Then install the Watchdog driver and program, which you can find on the official website – click here for the driver and here for the program. Enable Autostart for the program, and adjust the monitoring settings – enable network monitoring and type ‘,’ then enable process monitoring as well, typing in ‘cmd.exe.’

    Special features.

    A few more things you should do.

    Prevent your system from going to sleep using power settings.

    Be attentive not to have the motherboard touching any metallic surface (metal surfaces are conductive).

    Connect your SSD to the motherboard and secure it into place too.

    #3 Install the PSU

    Connect the motherboard to the power supply unit using the 24-pin connector near the CPU. Use the 8-pin connector to connect the CPU to the PSU.

    Then connect the SATA to the SSD. At this point, ensure the SSD has a power supply connection and that it has a SATA properly connected to the motherboard.

    You should zip-tie any extra cables that may get in your way.

    It is sometimes challenging to have the wires in place neatly, so be patient and use zip ties to hold the wires in position.

    With the PSU in place, install the Molex and the 6 pin or if otherwise, the 6 +2 cables into the power supply unit.

    The next thing is to power the GPU risers.

    Things like the cooling system need frequent checks, so consider getting one that won’t bog you down with constant failure.

    How to build a mining rig?

    How to build a mining rig may appear a daunting task at first but once you get everything you need, you will find it much easier than you initially thought.

    And therefore, the very first thing is to assemble everything you will need so as to save yourself the hassle of running up and down trying to locate this or that.

    It is also important to be accessible to:

    • Reliable electricity supply.
    • Ethernet (wireless can do, but Ethernet is the best).

    Here is what you need to start with:


    A motherboard is simply that big flat component of your computer that everything else plugs into.
