How to Build a Bitcoin Mining Rig: All You Should Know

How to Build a Bitcoin Mining Rig: All You Should Know

Do you want to develop a bitcoin mining system? Here’s everything you’ll need to get started, including the hardware and information you’ll need.

Cryptocurrency has been a crazy journey, and it continues to be so. I recall being given a couple of bitcoins when they were worth pennies on the dollar. Needless to say, I no longer possess them. With the price of bitcoin and other cryptocurrencies increasing again, cryptomining, which is a means to collect cryptocurrency without having to pay for it, has reawakened interest.

Check out the Bitcoin Mastery app to leverage advanced algorithmic technologies and ensure that you can identify and take full advantage of the best opportunities in the crypto market.

Let’s look at what makes a decent cryptomining rig and what equipment you’ll need if you’re serious about mining.

What Is Cryptomining?

On the most basic terms, you’re solving cryptographic equations using a computer (or computers) and recording the results in a blockchain. To elaborate, miners verify the hashes of unconfirmed blocks and are rewarded for each hash that is verified. Mining is a computationally expensive operation that necessitates cutting-edge gear if you want to make significant progress. Mining is not for the faint of heart, as it was in the days of the gold rush.

And, as with other high-end systems, the question isn’t so much how much you want to spend as it is how quickly you want to spend it. So, what kind of hardware is required to mine cryptocurrency?

What Is A Cryptomining Rig?

The “rig” is, in essence, a customized PC. It has all of the standard PC components, such as a CPU, motherboard, RAM, and storage. When it comes to graphics cards, things get a little out of hand. When it comes to cryptocurrency mining, it’s the GPU, not the CPU, that does the heavy lifting. For mining, you’ll need a fairly strong GPU, and you’ll almost certainly need more than one. Way more.

In fact, a mining rig can be thought of as a low-cost PC with one or more high-performance GPUs attached. Multiple graphics cards must be connected to a single system, which necessitates the use of a motherboard. If you’re going to push things to their limits, you’ll need more than one power supply unit (PSU).

You’ll also need a few more mining-specific equipment to get the mining rig up and running.

Considerations For a Bitcoin Mining Rig

When constructing a mining rig, keep the following points in mind:

It isn’t going to be cheap!

Power consumption should be factored into your mining equation because it might cut into your profits.

Because you’re not creating a standard PC, getting things to work might be a trial and error process involving a lot of tweaking with drivers. You woud have to be patient!

Why Are The Prices Of Graphics Cards So Astronomical?

Two factors are causing prices to rise:

  • Backlogs caused by supply chain concerns.
  • Most cards now have LHR (Lite Hash Rate) to limit mining speeds, making them less appealing for cryptomining. This is to prevent high demand from miners generating even more troubles. Because the cards mentioned below are not limited, the price makes them ideal for mining.

Motherboard

Asus B250 Mining Expert

Let’s start with the motherboard, shall we? The Asus B250 Mining Expert is a monster of a motherboard that can support up to 19 graphics cards. That’s a lot of information. The board isn’t new (it was released in 2017), and it’s finicky when it comes to setup (it requires a specific layout of AMD and Nvidia graphics cards). Asus has published recommended GPU layouts for 19-, 13-, and 11-card for this board, and while other layouts might work, I recommend sticking with what the manufacturer recommends, as straying from this is a recipe for serious — and expensive — headaches.

Yes, the price of this motherboard is skyrocketing, but that’s the nature of bitcoin mining. If you’re looking for something a little more affordable, the Monland B250C BTC Mining Motherboard is a good option. It’s a lot less powerful, but it’s a lot cheaper.
Asus recommends operating this motherboard with Windows 10.

CPU

Intel Core i5-6500

Overspending on a CPU for a mining rig is pointless because it’s the GPUs that do the heavy lifting. This quad-core Core i5 processor is ideal for this arrangement and pairs well with the motherboard mentioned above.

RAM

G.SKILL Aegis 16GB (2 x 8GB)

You’re also not going to go overboard on RAM. The motherboard supports DDR4 2400, and this G.SKILL 2x8GB package will suffice.

Storage

1TB SanDisk SSD Plus

I’d put a pair of these 1TB SSDs in there. They’re ideal for this application because they’re under $100 each. You could use HDDs, but I personally prefer SSDs these days.

PSU

Segotep 850W Full-Modular Power Supply

You may need many PSUs depending on how many graphics cards you have installed. It’s tempting to go for the cheapest option, but given how hard they’ll be pushed, I advocate spending a little more.

These Segotep PSUs are a nice middle-of-the-road price, yet they deliver consistent performance. Because it’s modular, you won’t end up with a tangle of wires on your mining equipment.

PCI-e Riser

FebSmart 16x to 1x Powered Riser 6-pack

Even if you’ve built a PC before, I’m sure you’ve never had to deal with PCI-E risers. A bitcoin mining rig differs from a regular PC in that all of the graphics cards cannot be directly connected to the motherboard, so risers are used to help you connect them indirectly.

For each card you connect, you’ll need one of these (other than the card that goes into the x16 PCI-e slot). This six-pack of powered risers is fantastic and ensures that your graphics cards have consistent power.

Non-powered risers are not recommended. I’ve had nothing but stability issues with them in cryptomining rigs in the past, so don’t make the same mistake I did!

This is a fantastic card that has everything you need in a mining rig. Overclocking potential abounds, as well as stability and excellent cooling. Another plus is that it’s a rather efficient card, resulting in decreased power usage and cheaper mining costs.

And, unlike many modern graphics cards, it lacks the LHR (Lite Hash Rate) feature that limits mining speeds.

Features

  • 24GB 384-Bit GDDR6X
  • Boost Clock 1725 MHz
  • 1 x HDMI 2.1 3 x DisplayPort 1.4a
  • 10496 CUDA Cores
  • PCI Express 4.0
