Recently, the profitability of cryptocurrency mining has begun to surge again. After a depressing 2022 for the crypto market, hash rates for Bitcoin have started to climb due to the BTC price rally, and with the highly anticipated Bitcoin halving on the horizon, experts predict that mining profits will skyrocket in the near future. Thus, there has been renewed interest in building one’s own mining rig in 2024.
If you’re considering joining the ranks of cryptocurrency miners, you may be wondering what components are needed and how to put it all together. In this article, we will delve into the essentials of creating a mining rig and provide a step-by-step guide to help you on your mining journey.
But what is crypto mining essentially? Let’s start with the basics.
Cryptocurrency mining is the process of creating new units of a digital currency by using powerful hardware to solve complex mathematical problems. This process is integral to securing decentralized and distributed networks, such as those used in blockchain technology.
The first and the most popular coin for mining today is Bitcoin, of course. As the first cryptocurrency invented in 2009, Bitcoin’s success and popularity sparked the creation of numerous other digital currencies using a similar mining model.
At the beginning stages of Bitcoin, mining difficulty was relatively low, allowing miners to obtain significant amounts of the digital currency. This presented a lucrative opportunity for early mining enthusiasts who profited immensely from Bitcoin’s increasing value over the years.
At its core, the crypto mining process relies on a consensus mechanism called Proof-of-Work (PoW). This mechanism involves miners using computational power to mine blocks of transaction data and add them to the blockchain ledger. The first miner to complete the task is rewarded with units of the network’s cryptocurrency.
Another popular consensus mechanism is called Proof-of-Stake (PoS), which was introduced as an alternative to PoW. Instead of using computational power, PoS relies on the concept of “staking,” or holding a certain amount of cryptocurrency and using it to validate transactions on the network.
The number of miners on a network directly impacts mining difficulty levels. As more miners join, the difficulty increases, and vice versa. This mechanism regulates the time it takes to mine blocks, preventing coins from being generated too quickly or too slowly. It helps to ensure consistent transaction processing times and maintain the integrity of the network.
Due to the increasing complexity of mining tasks, more and more computational power is required to mine coins successfully. Thus, specialized hardware is necessary today to earn profits from this venture effectively. As a result, miners often purchase powerful hardware units, such as ASICs and the latest NVIDIA GPUs, and sometimes many of these, to increase their chances of successfully mining blocks.
Enough theory – let’s get down to practice. Several key components are required to build a Bitcoin mining rig. Let’s take a closer look at each component and what role they perform in the overall rig:
The GPUs (graphics processing units) are the workhorses of a mining rig, responsible for performing the complex calculations required for mining.

Now that we have covered the essential components, let’s dive into the step-by-step process of building a mining rig:
Start by placing the motherboard on a static-free surface. Ensure that the CPU lever socket is in the released position.
Carefully insert the CPU into the appropriate socket, aligning the notches on the CPU with the socket. Lock the CPU in place by gently lowering the lever.
Be careful! It is not a good idea to bend the CPU pins. Also, for the best and safest result, read the manuals that come with every part of your rig.
Apply a thin layer of thermal paste to the top surface of the CPU. Thermal paste is necessary because it helps to create a better heat transfer connection between the CPU and the CPU cooler. It ensures that the CPU does not overheat, allowing the mining rig to run efficiently and avoiding damage to the components.
Next, attach the cooler, ensuring that it is securely fastened and making proper contact with the CPU. Connect the cooler’s power cable to the motherboard.
Insert the RAM modules into the appropriate slots on the motherboard. Apply gentle pressure until the RAM modules click into place. Ensure that the locking mechanisms on the RAM slots are secured.
If you have a PCIe NVMe storage card, it is better to connect it in this step.
Place the motherboard into the mining rig frame, ensuring that it aligns with the mounting holes. Use screws to secure the motherboard in place, taking care not to overtighten.
Position the PSU in the mining rig frame near the motherboard. Connect the necessary power cables to the motherboard, CPU, and GPUs. Ensure that all connections are secure and properly seated.
Attach the GPUs to the mining rig frame using risers or brackets. Connect the power cables from the PSU to the GPUs, ensuring that each GPU receives sufficient power. Secure the GPUs in place and ensure proper airflow between them.
Locate a free PCIe slot on your motherboard and connect the x1 end of the USB riser. Don’t worry about which PCIe slot to use; both x1 and x16 will work just fine. Once the riser is securely in place, it’s time to attach the GPU.
Next, connect the x16 end of the USB riser to the GPU. This will ensure that your graphics card is properly connected to your motherboard and ready to mine. Now comes the final stage of the riser installation – connecting a USB cable between the x1 and x16 USB riser cards.
To complete the connection, you’ll need to take care of power. Start by connecting power cables to the x16 end of the USB riser connected to your GPU. Depending on your PCIe riser model, this could be a 6-pin PCIe connector, 15-pin SATA, or 4-pin Molex cable. Lastly, connect the PSU’s PCIe 6+2 power cables to the GPU.
However, checking with your manual to install pin cables correctly will be better.
Connect the storage device (SSD) to the motherboard using the appropriate cables. If you have PCI NVMe storage, connect this to a free PCIe x16 slot.
Connecting PCI NVMe is better when you install your RAM.
Then, connect a monitor, keyboard, and mouse to the mining rig for initial setup. That’s it – your mining hardware is ready.
Now, it’s time to set up your software.
Power on the GPU mining rig and enter the BIOS settings by pressing the designated key during startup (often Delete or F2). Configure the BIOS settings to recognize all the connected hardware, enable above 4G decoding, and adjust other necessary settings.
Insert a USB flash drive containing a pre-configured bootable Windows OS into an available USB slot on the motherboard. Give it a moment to boot up, then proceed with the installation steps to install the operating system.
Turn off all additional functions and extras like OneDrive, etc. It won’t improve your rig’s mining efficiency. Download the latest drivers for your GPU for better performance.
Install the mining software of your choice on the mining rig’s storage device.

With your mining rig successfully built and configured, you can start mining cryptocurrencies. Monitor the mining rig regularly, adjusting settings and troubleshooting any issues. Stay updated on the latest developments in the cryptocurrency mining space to optimize your mining operations.
Bitcoin mining is a highly competitive and lucrative industry, with miners constantly seeking ways to boost their profits.
One key metric that miners use to measure the value of their computing power is the hashrate index – the amount of money earned per petahash (PH) of mining equipment. And according to recent data, 2024 may be an especially profitable year for Bitcoin miners.
On December 6, 2023, the hash price for Bitcoin surged to a staggering $110/PH/day. This is almost double the October 2023 numbers of around $60/PH/day. In other words, miners with just one petahash of equipment were expected to earn $110 per day in revenue – an increase representing potential profits of over 80% compared to just two months ago.
This impressive rise in hash price can be attributed to several factors, including Bitcoin’s ongoing price rally. On that same day, the price of BTC reached a high of $44,000 – a milestone projected to continue well into 2024. In fact, with the highly-anticipated Bitcoin halving event on the horizon, many analysts believe that BTC could reach historic highs.
What is halving? Many cryptocurrencies, including Bitcoin, have a halving mechanism in place. It reduces the rate at which new currency units are generated and promotes scarcity. For example, Bitcoin’s recent halving in May 2020 reduced the mining reward from 12 BTC to 6.25 BTC. The next halving is predicted to occur in 2024 and will further reduce the reward to 3.125 BTC.
But it’s not just the rise in Bitcoin’s price that has contributed to the increase in hash price. Transaction fees have also significantly grown, thanks to the rising popularity of Bitcoin-based non-fungible tokens (NFTs). These unique digital assets, often in the form of BRC-20 tokens, have become the latest craze for investors looking to diversify their portfolios.
So why should miners continue to invest in mining in 2024? With the current trend indicating a surge in hash price and transaction fees, it’s clear that this is a highly profitable industry with the potential for even greater returns.
