The dawn of mining, when an 8 GPU mining rig was not in sight

There are a lot of speculations about cryptocurrency started from the year 2008 when BitCoin made it to the headlines. Many people think cryptocurrency is a bubble ready to pop. The sentiment varies, which continues to leave a shroud of uncertainty over the cryptocurrency world. Volatility has started soon after the shift in central bank focus on cryptocurrencies. It was further exceeded when China decided to ban ICOs and the shutting down of Bitcoin exchanges. People start speculating it as the beginning of the end for the cryptocurrency.

I won’t say cryptocurrency is as popular as it was back in 2016 and 2017. But cryptocurrency popularity is picking up momentum again. Today the prices of cryptocurrency are very high, enough to attract investors. As of March 6, 2020 the prices of top 5 currencies are:

This is the right time to level up the mining game with an advanced 8 GPU mining rig. To help you, I am writing this article to share my knowledge and experience of an 8 GPU mining rig. 

So, shall we begin? Let’s first discuss Cryptocurrency mining. 

Cryptocurrency Mining – A Bird’s Eye view

Mining is a process of verifying cryptocurrency transactions and adding them to the block chain ledger. The process is also known as ‘altcoin mining’ and ‘cryptocoin mining.’ During the process, new coins add up into the cryptocurrency supply. This is the reason why the system works as a decentralized peer-to-peer network, without the need for a third party central authority.

In this process, miners compete against each other to solve cryptographic hash functions. These hash functions contain the data of the transaction. Whoever cracks the code first will authorize the transaction. In reward, miner earns a small amount of cryptocoins. For instance, a Bitcoin miner earns 2.5 BTC down from 25BTC when the process begins.

Bitcoin is the most popular mineable cryptocurrency in the world. The mining process of Bitcoin runs on a consensus algorithm called Proof of Work.

Note: Do keep in mind that not all cryptocurrencies are mineable.

To have the edge over other miners, you need a computer with specialized hardware. Here the need for GPU rig arises. Let’s discuss the main part of this article and get to know more about 8 GPU rigs.

What is a GPU Mining Rig?

It is a computer built with specialized graphic cards to fulfill the purpose of mining. It is like a regular computer with the same hardware and runs on the same operating system. But, a mining rig has more than one GPU (6 or 8), and they are placed inside specific GPU cases for efficient cooling. A GPU mining rig runs on more than one Power Supply Unit (PSU). Its total power consumption often exceeds 1000 watts. 

Now the question here is how to choose or build an excellent 8 GPU mining rig. So, let’s have some discussion on this point as well.

What will you need to start mining with 8 GPU mining Rig?

To start a cryptocurrency mining business, you will need the following things:

  1. A computer with a specialized GPU 
  2. A subscription of a legitimate mining software package
  3. Membership in both an online cryptocurrency exchange and an online mining pool.
  4. High Watt power supply
  5. Fast Internet Connection
  6. A Generator for a backup power source
  7. Space with proper ventilation to place the rigs

Cryptocurrency value is increasing over time, which increases the competition. Big organizations and enterprises have entered this business. Evaluating the factors before buying the rig will help you reduce the overall cost. Let’s discuss these important factors.

Essentials of Cryptocurrency mining

Many people don’t believe in cryptocurrency, but we cannot deny that at the moment there is a lot of speculation that can be done in this market.

Mining is a way to validate cryptocurrency transaction in exchange for money.

In order to be able to mining cryptocurrency it is necessary to have some technical skills, software and not very inexpensive hardware.

In this article we will find the best combinations for optimizing costs with profits.

Factors to Consider before buying 8 GPU Mining Rig

The important factors to consider while shopping for an 8 GPU mining rig are:

  • The memory GPU boasts
  • Power demand
  • Cost

It is time to discuss each factor in detail.

Cost of the 8 GPU Mining Rig

Cost is the most important factor to consider while purchasing a mining rig. Don’t forget the cost that incurs after buying the rig. Running and maintaining a mining rig can be expensive. The monthly recurring costs include internet charges, electricity bills, etc. 

The cost of building an 8 GPU mining rig varies based on the components you are choosing. It differs from brand to brand and then from the latest models to the older ones. For example, if you go for AMD Radeon RX 580, it will cost you around $185 to $200. The cost also depends on when and from where you will buy it. In 8 GPU rigs, you have a choice to use all 8 GPUs of the same brand and model, or you can always mix and match. Let’s say if you buy 8 AMD Radeon RX 580, it will cost you around (8x$200) $1600. 

At the initial stage of cryptocurrency mining, you won’t yield large profits. Thus, forecasting the cost of GPU rig as well as a recurring monthly cost is very important. It is important to know your expenses and revenues to maximize profits. 

Apart from the cost of the rig, there are other factors that matter. These factors are: 

Hash Rate

It is the number of calculations a rig can perform in one second. The higher the hash rate, the better the rig. To compete against other miners, the efficiency of the mining rig depends on the hash rate. The higher the hash rate, the more electricity a mining rig will consume. Hence, the next factor to consider is Power Supply. 

Power Supply

Electricity consumption is one of the main factors that you should keep in mind. Let say you decided to go with AMD cards; now you have a variety of options available. For instance, you can either choose AMD RX 480 or AMD RX 580. Both of them have almost the same hash rates. But, a single card of AMD RX 480 requires 150W, whereas a single card of AMD RX 580 takes about 185W. Multiplying these power consumption 8 times, you will get your answer. 

Temperature

The temperature surrounding the GPU rig is very crucial to the life of your machine. There should be a proper air conditioning system installed at the space where you will place the rig. Currently, I am mining Monero and Ethereum using the same rigs. I have seen that as I move from Monero to Ethereum, the temperature rises from 12 to 15-degree centigrade. My rigs in the garage cause the temperature to reach up to 35-degree centigrade. Whereas, the temperature outside my home is -2 degrees. Proper ventilation is essential to keep the temperature constant. 

The one thing I would recommend to consider while building an 8 GPU rig is how much heat the GPUs will create. Knowing this fact will help you manage the temperature of the surroundings.

Cost Of The 8 GPU Mining Rig​

When calculating the cost of an 8 GPU mining rig, it is important to consider the performance and the consumption (and any fixed costs) that such a rig would output over time.

The main factors are:

  1. Hash rate
  2. Power supply
  3. Temperature

Why you need 8 GPU Mining Rig – Advantages over Disadvantages

New rigs are coming in the market with high hash rates, making the competition tougher. With an 8 GPU mining rig, you can mine two or more coins at the same time. 

Let’s discuss the advantages and disadvantages of 8 GPU Mining Rig in detail.

Advantages of 8 GPU Mining Rig

Ability to Work with Multiple Coins

As mentioned earlier, the biggest advantage of using a rig is the ability to mine more than one coin at a time. For instance, you can mine altcoin that uses the Ethash algorithm along with ethereum. You can switch from mining one cryptocurrency to another depending on the profitability.

Better Resale Value

You can always sell your GPU rig as all the parts used to assemble the rig are usable. You can sell Graphic cards to avid gamers who are always in need of second-hand Graphic cards.

Low Electricity Usage

A GPU rig consumes less electricity compared to an ASIC and FPGA. The reason for consuming low power is the lower hash rates. If you place a GPU rig in an open area, its electricity consumption will reduce further.

Warranties

GPUs come with 1 to 3 years of warranty. If you buy the GPU from a well-reputed manufacturer like Nvidia and AMD, you can get up to 5 years of warranty. The repair service is also included in the warranty.

Environmental Friendly

GPU rigs are environmentally friendly as they produce less heat and noise. You can even place it in your house.

Disadvantages of a GPU Rig

Low Profitability

GPU rigs are less profitable compared to ASIC and FPGA because they offer low hash rates. We will later discuss this controversy in detail to check whether a GPU is better than ASIC or FPGA. 

High Initial Setup Cost

To set up an 8 GPU rig, you will need 8 GPU cards, along with other components. The cost of assembling an 8 GPU mining rig is higher. If you are not a tech-savvy expert, add the cost of hiring a technician too. 

Shortage of Graphic Cards

Demand for high-end GPU cards is very high because of the online gamers. The high demand for GPU cards by gamers and miners makes it more expensive too. 

I hope you are clear now about the advantages and disadvantages of a GPU mining rig. Now, I will share some of my experience of building an 8 GPU mining rig.

How to Build an 8 GPU Mining Rig?

Now, we will discuss how to build an 8 GPU mining rig in the best way to optimize your profit and lower your cost. First, I will explain what components you will need to build an 8 GPU mining rig.

Component to build an 8 GPU Mining Rig

I will include all the components to build an 8 GPU mining rig along with suggestions. 

Note: It is important to mention that the prices may differ and keep changing on a timely basis. So, whatever prices mentioned in the article are not 100% guaranteed. 

8 GPUs – The heart of the Rig

To build an 8 GPU mining rig, we will need 8 GPUs. There are two options available, either use eight GPUs of the same brand or use the combination of two or more. I prefer using the same brand as it is easy to adjust the temperature of the machine.

I chose an AMD RX Vega 56 card that cost me $400 each. You will need 8 of them so;

1 RX Vega 56 = $400

8 RX Vega 56 = 8 x $400 = $3200

It is expensive, isn’t it? But you have a choice to go for a lower rate card like AMD’s Radeon series RX 560, which will cost you around $200 each. 

Let’s move on with the process of building our machine. 

The next component you need is a motherboard.

ASUS PRIME Z270-A LGA1151 DR4

image of asus prime z270a. To build an 8 GPU mining rig, you will need a motherboard that has 8 PCI-E slot. Asus Prime Z7270-P is one of the best. The Asus motherboard has 7 PCI-E slots and 2 m.2 slots. We will attach 2 more PCI-E slots in one of the 7 slots. This way we will have 9 PCI-E slots. We will attach 8 GPUs in 8 of them and a storage device in the ninth one.

The specification of the Asus Prime Z7270-P motherboard are:

  • It supports DDR4 RAM
  • It supports Intel processor
  • Price = Affordable (cheap compared to other options)

Now, you will need to buy 8 PCI-E RISERS in the next step.

PCI-E 16x to 1x RISERS

PCI-E-16x-to-1x-RISERS image.RISERS are very important to attach GPUs to the motherboard. You will need 8 of them since we have selected Asus Prime Z7270-P, so we will also need 2 m.2 PCI-E extenders. Attach the RISERS in the PCI-E slots and connect them with the 8 GPUs. Let’s move ahead, and in the next step, you will need RAM.

 

Ballistix Sport LT 4GB Single DDR4

Image of: Ballistix Sport LT 4GB Single DDR4. I chose Ballistix 4GB DDR4 RAM. You can also select an 8GB RAM, but that will not make any difference in mining. So, I tried to be on the lower side and reduced my cost by choosing 4GB RAM. 

Next, you need a CPU or Processor.

Intel Celeron

Image of the Intel Celeron box. In connection with the Asus Prime motherboard, I choose Intel Celeron as my processor. It doesn’t matter to go for a high-end processor as we are performing GPU mining, not CPU mining. The need for a processor is only for booting up a mining rig and running the mining software. Choosing Intel Celeron has saved my cost.

SanDisk SSD PLUS 120GB

Image of a SanDisk SSD Plus 120GB. Your mining business depends on electricity and time. Time is money, and this statement stands in the case of mining. I choose SDD (Solid state drives) over HDD (Hard Disk Drive) for two reasons. 

First, when you set up your mining rig for the first time, you will need to reboot your system a lot of times. If you are using the HDD, it won’t be delightful. HDD takes more time to reboot than SDD. 

Second, SDD uses flash memory to deliver superb performance and durability. A hard drive device consists of lots of small moving parts like magnetic heads, spindles, and spinning platters. If things go wrong, you could lose all your important data. Unlike HDD, SDD without moving parts is more durable, runs cooler, and uses less energy.

Your mining rig without a power supply is useless. So, let’s move on to the next step. 

EVGA 1000 GQ 80+ GOLD 1000W PSU

It is time to do some math.

One GPU card will consume 185 W of electricity.

image of EVGA 1000 GQ 80+ GOLD 1000W PSU. 8 GPUs will consume = 8 X 185 = 1480 W

The CPU, SSD, motherboard, and other components will consume around 250W. It means we need 1480 + 250 = 1730W of electricity supply. Instead of going for one PSU, I am going with two 1000W PSUs.

EVGA is one of the best power supply manufacturers in the market. I chose 2 PSUs of EVGA.

To connect the PSU, you will need an adapter cable. Let’s see which one I choose.

Thermaltake Dual 24-Pin Mining Adapter Cable

image of Thermaltake Dual 24 Pin Mining Adapter Cable. For 2 PSUs, we will need 1 Adapter cable. I choose Thermaltake Dual 24-Pin Adapter Cable because it is cheap. It will connect to both PSUs and then connect with the motherboard.

With so many components, you will need the right case to fit them all.

GPU Mining rig Open Air Frame Case

image of GPU Mining rig Open Air Frame Case. Building your own 8 GPU mining rig case might save your cost, but it is not easy. I picked Veddha Professional 8 GPU Miner Case. It is one of the best in the market with a proper cooling system to keep the GPUs temperature under control. 

At last, you have your 8 GPU mining rig ready to start mining. The cost can vary depending on your choices for each component. Keep this in mind that the more you spend, the more you will earn. 

When it comes to the earning of GPU mining rig, it is always compared with ASIC and FPGA. It is important to address this concern to give a better idea to my readers.

How to Build an 8 GPU Mining Rig?

Here are the components that you need to build an 8 GPU mining rig:

  • 8 x RX Vega 56 or AMD Radeon series RX 560 (which is more affordable).
  • 1x Asus Prime Z7270-P.
  • 2 x m.2 PCI-E extenders.
  • 1 x Ballistix 4GB DDR4 RAM.
  • 1 x Intel Celeron.
  • 1 x SanDisk SSD Plus 120GB.
  • 2 x EVGA 1000 GQ 80+ Gold 1000W PSU.
  • 1 Thermaltake Dual 24-Pin Mining Adapter Cable.
  • 1 x GPU Mining Rig Open Air Frame Case

GPU is not profitable compared to ASIC and FPGA

First, let me explain ASIC and FPGA for those who do not know about these terms. 

ASIC

Application Specific Integrated Circuit is a device designed to fulfill a designated purpose. ASIC is the top choice when it comes to mining. They are much faster and cheaper compared to a mining rig. But, they are only designated to mine one type of cryptocurrency. You cannot mine Ethereum and Monero at the same time using an ASIC. 

ASIC may cost you less when you buy it. But, the maintenance charges are very high compared to a GPU. First of all, it consumes a lot of electricity which results in huge electricity bills. 

You need to rent a space to place your ASIC unit because it heats a lot and makes too much noise. Even your neighbors, three floors down, can hear it. It would help if you had proper cooling and ventilation service to reduce the heat ASIC produces. 

The machine performs one purpose only. It has a poor resale value, which increases the overall cost and decreases profits compared to a mining rig.

FPGA

FPGA stands for Field Programmable Gate Array. It is a reconfigurable integrated circuit programmed to work as per the intended design. An FPGA can perform functions like a microprocessor, an encryption unit, or a graphics card. It can also perform all these functions at the same time. The FPGAs are designed using hardware description languages such as Verilog and VHDL. 

GPUs are good for compatibility. If an algorithm changes, the new software can run on older chips. But, FPGAs are more problematic to adapt to the change. 

Hence proved that a GPU is more profitable than an FPGA in the long run. 

To build an 8 GPU mining rig, you need the best high-end graphic cards. Let’s check out the list of top 3 GPUs.

Skimmer Box

GPU is not profitable compared to ASIC and FPGA

While it is true that GPU is not as profitable as ASIC or FPGA, there are more details to be discussed:

ASIC

  • ASIC devices cannot mine more than one currency in the same time.
  • ASIC maintenance costs are much higher than GPU, not to mention the electricity costs.
  • ASIC is extremely noisy because it needs powerful ventilation, to the point that it would bother your neighbors as well.
  • ASIC devices would probably not have a good resale value.

FPGA

  • These are programmable integrated circuit.
  • They are more difficult to adapt to technology upgrades.
  • GPUs may be more profitable on a long run.

Top 3 GPUs for Mining Rigs

Based on the factors discussed earlier, here’s a suggested list of top 3 graphic cards. These graphic cards are most suited to build an 8 GPU mining rig.

The price of the GPU starts from $500, which is on a higher compared to many other options available in the market. If you are planning to run a mining business for a long period, then it is the best decision to go with GTX 1070. GTX 1070’s strong 1440p performance makes it attractive for both the gamers and miners.

Nvidia GeForce GTX 1070 comes with 1,664 CUDA cores and a boost clock of 1,178 MHz. Plus, an additional 4.5GB of GDDR5 VRAM. Nvidia GeForce GTX 1070 runs on Pascal’s mighty 16nm FinFET processor, enabling 6.5 TFLOPs of performance. Nvidia also launched a Founder’s special edition of GTX 1070. One of the issues with the Founder’s edition is its price. It may cost you around $580 (£395 or AUS$784). You will pay higher only for a slight change that is an earlier release date and sub-par cooling.

Let’s check what coins are best to mine with the Nvidia GeForce GTX 1070.

Conclusion

The cryptocurrency mining business is not dead yet. The popularity of cryptocurrency may not be the same as it was a few years ago, but new currencies are still coming in the market. Running a mining business may sound easy, but it isn’t if you don’t have the right knowledge. I have shared as much information I could to help you make your decision. If you decided to enter the business, do remember that selecting the right GPU will make or break the deal for you.

Understanding the competition and changing dynamics in the industry is very important. You will need to keep yourself updated for new trends and happening. In my experience, I witness that depending on one currency is not a wise decision. With an 8 GPU mining rig, you can switch between different cryptocurrencies.

Please share your feedback about this article in the comment section below. And, let me know if I may need to improve my techniques at any point. If I have missed adding any GPU better than the three which I listed above in the article, please feel free to inform me. It will be a significant contribution from your side to all other miners in the industry.
