How to Build an Ethereum Mining Rig

March 06, 2023 - 8 min read

A computer system explicitly created to mine Ethereum is known as an Ethereum mining rig.

Ethereum Mining Rig

You’ll need a mining rig if you intend to mine Ethereum yourself at home. It is a powerful machine that is especially suited for generating cryptocurrency. It will be interesting to learn for people who are just getting started that Ethereum mining rigs consist of a computer with many graphics cards. This powerful computer is equipped with several GPU cards, a strong motherboard, a power supply, and a cooling system to combat the heat produced by your mining setup.

Ethereum is the network that supports Ether, a blockchain-based cryptocurrency. One of the most attractive ways to earn money in the market is to mine cryptocurrencies (aside from buying and holding the asset, of course). It is possible to mine Ethereum using a standard gaming machine. However, to maximize efficiency, you can construct a unit whose sole goal is to mine Ethereum. This takes some time and is not remarkably inexpensive. On the other hand, it means that you are mining Ethereum significantly more efficiently than a regular computing system.

While many projects are abandoning mining in favor of proof-of-stake, it’s not too late to become involved, especially if you’re planning to build an Ethereum mining setup. Let’s investigate the Ethereum Mining Rig.

Ethereum Mining Rig

An Ethereum mining rig is identical to any other computer you would build, except that all the components reside in an open location. All-in-one computer systems are designed and constructed to mine Ethereum or other cryptocurrencies. The essential components of Ethereum mining equipment are the power supply unit and the graphics processing units (GPUs). This system can execute around 27 million mathematical equations per second with a single graphics card.

They enable high-end gaming computers to have the capacity to handle the stunning graphics of contemporary PC games. They are also excellent for making as many predictions as possible regarding the hashes of Ethereum blocks. Currently, 600 trillion mathematical calculations are performed per second on the Ethereum network. Typically, Ethereum mining rigs contain at least two of these GPUs. However, they can accommodate many more individuals. The number of mining processors you choose will depend on your budget for designing your mining rig.

Components Required for building a Mining Rig

1. GPU

GPUs are known as an essential component of a mining rig, as they are the components that create income. Multiple GPUs are installed on a single motherboard, processor, disk, and memory in a mining rig. Only a few basic skills are required to construct a rig if you have all the necessary equipment. You only need fundamental PC construction knowledge.

The ROI is calculated by dividing the GPU purchase price by the daily net profit. Other GPUs that can be used to construct a mining rig are:

  • NVIDIA RTX 3060 Ti
  • NVIDIA RTX 3080
  • NVIDIA RTX 2060
  • AMD RX 5700 XT
  • AMD RX 5700
  • AMD RX 580 8GB
  • AMD RX 570 8GB

2. USB PCI-e risers

These are for keeping the GPUs away from the motherboard and making it feasible to spread them further away from each other. They are also used to keep the GPUs away from each other. The risers used are one hundred times less expensive than the standard ones used in PC gaming systems.

3. CPU

For the goal of mining, GPUs perform a better job; therefore, we tend to acquire a CPU that does the bare minimum because we are not counting on it as much as the GPU. The CPU is typically described as the computer’s brain, and it is often considered the most crucial component. When we mine, we will be using a graphics processing unit. You can select a CPU with a moderate or low level of performance for the miner. You should get a processor from the 8th or 9th generation of Intel’s 1151 Socket.

4. RAM

The users should be aware that there is no correlation between RAM size and mining performance, so using between 4GB and 16GB of RAM would be fine. Consider the operating system used for mining and the presence or absence of virtual memory when determining the optimal RAM capacity. For example, if you’re using ethOS, you can get by with 4GB RAM, but if you’re using Windows without virtual memory, you need at least 8GB RAM. RAM from leading manufacturers can be used, but it is always prudent to ensure it is compatible with your motherboard.

5. Risers

PCI Express risers make it possible to elevate the graphics processing unit (GPU) above the motherboard, which improves cooling and increases airflow.

6. Power Supply Unit (PSU)

Varied GPUs require different levels of power and watts. Hence, the power supply or PSU will vary depending on the number and types of GPUs used. GPU power is measured in watts. A decent rule of thumb for selecting the proper PSU is to calculate the power required by individual components and then choose a PSU that can provide more power than the sum of the energy needed for all components. For example, if we have four GPUs, each requiring 200 Watts, we need a power supply that can deliver more than 800 Watts, in addition to the power requirements of the CPU and motherboard.

7. RAM

Experts recommend a 128GB SSD for Windows 10 mining. An HDD will also suffice. Additionally, we recommend at least a 16 GB USB flash drive for Linux miners. You may use 8GB or even 4GB with NHOS.

How to build an Ethereum Mining Rig

Ethereum Mining Rig

Once you have successfully gathered all the necessary components, you must begin building the rig. Initially, it may appear daunting, but if you follow the instructions precisely, it will be as easy as assembling a Lego set. Let’s build an Ethereum mining rig consisting of 6 GPUs.

Step 1: Connect the Motherboard

Users should put their motherboard with 6 GPU+ support outside the mining frame. Experts recommend placing foam or an anti-static bag beneath the shipping box. Users need to ensure that the CPU socket protection lever has been released.

Step 2: Attach the processor to the motherboard

The CPU is connected to the motherboard’s socket. Users must precisely align the pins with their corresponding slots when installing the CPU to the motherboard. If the arrangement is correct, all the pins will fit without difficulty. Rotate the processor immediately before insertion to align its pins with the slots on the motherboard. Some CPUs lack pins, necessitating greater care while aligning the CPU with the slots. Whenever feasible, utilize a guide or manual for the specific motherboard or CPU.

Step 3: Installing RAM

The subsequent step is the installation of RAM, or system memory. Inserting the RAM module into the RAM socket on the motherboard is straightforward. After opening the side brackets of the motherboard slot, carefully insert the RAM module into the RAM socket.

Step 4: Attach the Motherboard to the Chassis

Motherboards will be positioned mainly on the underdeck of the mining frame, while GPUs will occupy the upper deck. Be cautious not to scratch the Motherboard. If you have mining equipment with a metal frame, the Motherboard should only come into contact with the frame at the screw holes. Tighten the screws to install the motherboard securely.

Step 5: Attaching the Power Supply Unit, or PSU

Ensure that it is close to the motherboard. The power supply cable is primarily connected to the 24-pin (20+4) motherboard connector. This will provide power to the motherboard.

The PSU contains at least three groups of power connections to power the various components of your mining rig. The power connectors labeled PCI-e are used to power the GPUs by simply connecting them to the GPU power connectors, while the PSU connectors designated CPU are used to power the CPU.

The 8-pin power connector for the CPU should be attached to the motherboard closest to the CPU. As the PCI-e 6+2 power conductor and the CPU connector are both 8-pin connectors, you must never mix them. In addition, the CPU cables are thicker than the PCI-e cables.

Step 6: Connect USB risers

The x16 USB riser must be assembled using the PCI-e x1 connector, which is shorter. This must be attached to the motherboard. An electrical connection is required to power the risers. Depending on the model of your riser, you may need PCI-e six-pin connectors, a SATA cable, or a Molex connector to attach it.

Step 7: Attaching GPUs

The users should use the USB riser to secure the frames’ graphics cards. First, connect the PCI Express 6+2 power connectors to the GPU. Later, you must attach these connectors to the remaining 5 GPUs. Users must ensure that the cords are properly connected. Next, the users should click the display on the graphics card associated with the primary PCI-E slot.

Final Thoughts

The users might believe that the cost of the hardware components is the most expensive aspect of Ethereum mining. However, electricity will significantly reduce your profits. Therefore, always choose the least expensive service. When it comes to making a profit, many individuals pick Ethereum trading. If you decide to do so, consider Coinbase, Binance, or Coinmama. These digital currency exchanges are among the most trustworthy.

It is also not worthwhile to purchase used GPUs for your mining equipment. They may save you some money initially, but they are unlikely to operate as efficiently as new ones and have a far shorter lifespan. Instead, you can join numerous forums and organizations to learn how to construct mining rigs from scratch for your GPUs and cryptocurrency of choice. These forums also aid in the resolution of mining-related issues.
