How To Build A Mining Rig: Step By Step Guide

Want to know more about how to build a mining rig? Mining cryptocurrencies is one of the many ways to earn cryptocurrency. Bitcoin was one of the first coins you could mine but these days their hundreds if not thousands of new cryptocurrencies you can mine. 

So for this guide, we want to cover the steps in building your very own mining rig. Not only will you learn how to build one but also what mining hardware you should use too. However, it is always best to determine what your mining profitability will be first before ever attempting such a task. 

Determine Mining Rig Profitability 

Before ever attempting to build a mining rig its always best to figure out what your electric rates are first. The fact is that the mining rigs do consume a fair amount of electricity which can eat into your mining profits. 

Once you’ve established what your price per kWh is you can use sites like whattomine and cryptocompare to get a baseline of what your projected daily profits will be. However, keep in mind that the crypto markets are extremely volatile and change daily. 

Therefore you should consider starting small and get a feel for it by not investing more money than you can afford to lose. We state this to not disenchant you from pursuing mining cryptocurrencies yet as a fair warning to not put your financials at harm. 

Choosing The Right Mining Rig Hardware

Below is a list of common parts that you will need to build a GPU mining rig. Making sure you get the right part will ensure you get your rig running promptly and efficiently. Obviously, the plan is to get the best deals possible when it comes to buying mining hardware but going with the cheapest on some parts is not always the wisest if you wish to have a stable running rig. 

MotherBoard

The motherboard you choose will have an impact on what CPU you get and Ram as well. Be sure to research what form factor your motherboard supports before settling on your Ram and CPU. For example, this motherboard supports DDR4 ram and has an LGA 1151 socket that supports 6 through 7 Gen CPU. Therefore I must purchase DDR4 ram and a 6 to 7 gen CPU that is of an LGA 1151 socket size to match the motherboard. Also, make sure the motherboard has enough PCIe lanes to support the number of GPUs you’re planning on running. If you need help choosing a mining motherboard then use this guide.

CPU

As stated earlier once you have the motherboard picked out you can then choose a CPU that is compatible. For most mining rigs the best route to go is with the Celeron or Pentium processors. The only way I would personally recommend going with a more costly CPU is if you were building a cross-functional gaming mining rig. However, it’s not uncommon to go with something like an AMD Ryzen CPU but then you will need a different motherboard that supports that particular CPU. Be sure to check out our guide to learn more about the best GPUs to use for mining. 

RAM

Just like the CPU, the RAM needs to be supported by the motherboard as well. Most of the mining motherboards these days support DDR4 RAM. The big question is does RAM matter and to what extent? It does come into play when choosing what operating system you’re planning on running. For Windows 10, I personally recommend 8 GB of RAM. However, if you plan on using a Linux based mining software like HashR8 OS, then 4 GB of RAM will work just fine. Check out our guide to see what brands I like to use for most of my builds. 

SSD

When it comes to choosing the right disk space it again all boils down to what operating system your planning on using. For Windows 10 plan on a minimum of 60 GB of storage however, if you use a Linux based OS such as HashR8 then a 16 GB thumb drive will work just fine. Most of the mining rigs I build run on windows 10 and I like having extra space to download other files so I tend to go with 120 GB SSD. The most popular and affordable brands I use are Kingston and SanDisk. Check out our guide.

Mining Risers

Mining Risers are the least expensive component to building a mining rig but there not the least important. Mining risers are what allow the motherboard to support multiple GPUs in a way that allows each GPU to be spaced out. Mining Risers also the number one reason why mining rigs crash as this component is known for going faulty quite frequently. They’re cheap and so I always recommend not only buying one per GPU but also it nice to keep a few spares around in case one goes bad which again is quite common. See our guide to learn about which mining risers we prefer.

Power Supply

The power supply is another critical piece to building a mining rig as its responsible for supplying power to all the major components to any computer. When choosing a PSU its important to buy one that has more than enough wattage to supply the GPUs with enough power to mine efficiently. The size that you need will ultimately depend on the quantity and model of GPU your planning to use to build your rig. Read our guide on power supplies for mining cryptocurrency.

GPU

There’s a lot of Graphics cards you can use for the purpose of mining, however not all created equal. Some are more efficient than others. This component will make up the bulk of the cost associated with building a mining rig as GPUs can range from anywhere from 200 dollars to on upwards of 700 dollars USD. If you are in the market of buying GPUs to use for mining be sure to check out my guide on best GPUs for mining using the link down in the description. Check out our guide on the best GPUs for mining in 2020.

Mining Rig Frame

You can build one custom or buy one. The Veddha Mining Rig Frames are quite cheap however I prefer to build my own custom frames. To be clear there are a lot of ways you go about choosing a mining rig frame. Whether you are looking to buy one or build a frame there’s a link in the description below to help you decide what will work best for you. See our guide on how to build your own frame and some of the best ones to purchase.

How To Build A Mining Rig

Step 1 Install The CPU

The first step to building any mining rig is to install the CPU on the motherboard. A few things to note on this step are to be careful to not touch the bottom part of the CPU or any of the pins on the motherboard. 

Also, make sure you line the markings on the CPU up with the markings on the motherboard. Furthermore, be careful not to touch the thermal paste on the CPU fan and make sure you lock in and secure the fan properly. Additionally, make sure to plug the 4-pin fan cable into the proper 4-pin port on the motherboard. 

Step 2 Install The RAM

Up next is to install the RAM to the motherboard. This step is pretty simple as the RAM will only fit one way into the RAM slot on the motherboard. Don’t be afraid to push down on the RAM to ensure its fully seated into the RAM slot to make sure its pushed in all the way. 

Step 3 Install Motherboard

Up next is to attach the motherboard to the frame. Again this step is pretty straightforward but there few things to caution. 

First off to make sure you’re using a regular screwdriver to hand tighten the screws making sure that you only screw them in snug so you don’t crack the motherboard. Also, make sure to use at least 5 screws to ensure the motherboard is properly secure the frame. 

Step 3 Install Power Supply

Installing the power supply is another simple step to achieve. Ideally, you would want to attach the power supply to the frame so it doesn’t move around. Also, you will want to attach the 8-pin CPU cable and 24-pin cable to the power supply and then attach them to the proper ports on the motherboard. 

Step 4 Install SSD

In order to install the SSD, you will need to attach a 15-pin SATA cable to the power supply and then attach it to the SSD. Also, there’s a short cable that should have come with your motherboard that allows you to attach the SSD to the motherboard. 

Step 5 Adjust Motherboard Bios

In order to adjust the motherboard BIOS, you will need to access the BIOS menu first. Doing this can be done by powering on the rig and pressing the delete button continuously while the system boots up. Once inside the BIOS menu, there will be a few settings you will need to adjust. 

Please note that the settings you will need to adjust will vary depending on the motherboard you choose. Make sure to research which settings you will need to tweak in the BIOS to ensure your rigs run properly.

Step 6 Install Windows 10

When it comes to installing windows 10 there are a few ways you can go about this. For starters, you could buy a licensed copy online from amazon. Or you could download a free version of windows 10 and flash it to a thumb drive to create a bootable disk. 

We recommend going with the free version to save on costs. Make sure to watch our mining rig build video on this step to get windows 10 installed properly. 

Step 7 Adjust Windows 10 Settings 

Once windows 10 is installed and fully updated theirs some settings you will need to adjust. The first one is to make sure to adjust the power settings to ensure the rig never turns off or goes in hibernation mode. 

Other settings include adjust virtual memory and disabling windows defender so you can run mining programs without interruptions. Again please refer to out mining rig build video for more help on this what setting to adjust. 

Step 8 Install The First GPU

Now that you have the operating system installed its time to install the first GPU. To do this you will need to attach a riser to the GPU and then attach the GPU to the mining rig frame. 

From here make sure that the riser is attached to one of the PCIe lanes on the motherboard and then attach one 15-pin SATA cable from the power supply to the riser itself. Also, you will need one VGA cable coming from the power supply to the VGA port on the GPU. 

Step 9 Install GPU Drivers And Mining Software And Test The First GPU

Once you have the GPU properly installed and all the cables secured you can begin testing the first GPU. However, you will want to make sure you have the latest driver installed for your particular GPU. 

Once the drivers are installed you can download mining software to run a test on the GPU to ensure everything is working properly. This step may seem complicated but again please refer to our mining rig video for further instructions.

Step 10 Install The Rest Of The GPUs

Once you tested and confirmed the first GPU is working properly you can begin installing the rest of the GPU to rig. So your basically just repeating the process in Step 8. Again make sure to check all the cables to ensure their properly secure. 

Also, be sure to not overload your 15-pin SATA connections with more than two connections per cable. 

Step 11 Reinstall The Drivers

Once the rest of the GPU is installed you may need to reinstall the drivers. Sometimes this is not the case but in some cases, you may need to uninstall the drivers with a software called DDU.  

You can check the make sure the drivers are properly installed by right-clicking on the windows icon in the bottom left corner of your screen. Then go to the device manager and click on display adapters. If all cards are recognized then you good to go to the next step. However, if you have yellow caution symbols next to them or not all the cards are being recognized by the device manager then you going to have to wipe the drivers clean and reinstall new drivers. 

Step 12 Adjust Overclock Settings

Once you have the GPU installed and properly seated with drivers you can begin overclocking them. Overclocking allows you to optimize your GPU for max mining performance and power consumption. 

To do this you will need software like MSI afterburner installed on your mining rig. This will allow making an adjustment to the power and core and memory clock settings. This will vary greatly depending on the GPU being used and the coin you want to mine. 

Again please refer to our mining rig build video to get further details but keep in mind that you will need to find your own settings based on the hardware you use and coin your planning to mine. If you need help then you can always join our FB group for support

Step 13 Retest The GPUs And Configure Miner

Once you have the overclock setting adjusted you can begin mining. However, you will need to adjust your mining software so that the coins you mine are going into your wallet. In our example, we used Claymore 15 which allows you to mine any Ethash coin available. 

However, the nice thing about building a GPU mining rig is the fact you can mine a wide variety of coins. Sites like whattomine can provide insight into what coins might best to mine for the hardware you choose.
