If you were wondering how to build an affordable mining rig step by step, then this 1050ti 4GB eight GPU rig build makes a great option. Not only do these GPUs make a great low-cost mining rig but their very energy efficient as well.

The 1050 ti cards can also mine a wide variety of cryptocurrencies like Ethereum and Ravencoin to name just a few. However, these type of rigs builds may not be the fastest at mining cryptocurrencies, but in some cases, they can be the fastest to ROI.

Most of this is due to the lower cost advantage you have when buying a lower series GPU.

Another nice advantage with these types of mining rig builds is they tend to be low heat, which is nice if your running one or two rigs inside a home.

So I wanted to create this helpful guide to show new miners how to build a reasonably cheap mining rig step by step. Not only will I show how to build this mining rig but I’ll also show you how to set up and start mining Ravencoin and Ethereum with Overclock settings as well.

How to Build a Low-Cost Mining Rig

There are a number of GPUs you could make a cheap mining rig from so don’t just settle for the 1050 ti if you can find better deals on 1060 6GB they might be better. For everything else try to use the recommended parts as some form factors will only work with select hardware.

I do want to mention further that the overclock settings will work with just about any version of 1050 Ti 4GB. Just remember if you go with another series of card you will need to use other overclock settings.

Mining Rig Parts List:

Step 1: Install the CPU

Installing a CPU is relatively easy, but you need to be careful in handling it and be sure not to touch the side with all the gold contacts.

The first thing you need to do is open the latch for the CPU socket located in the center of your motherboard.

Once open you can begin to remove the CPU from its packaging and start looking for a triangle or notch located on one of the CPUs four corners. The same notch or triangle is also located on one of the four corners of the motherboards CPU socket.

Be sure when installing any CPU that these markings always line up to ensure the CPU is seated correctly inside the motherboard housing.

After you made sure the CPU seats correctly you can then lock the CPU in place with the lever and begin installing the CPU fan.

One thing to note about CPU fan is it has thermal paste applied to the bottom of the attached heatsink that you don’t want to touch so be careful when opening.

The fan has four legs which snap into the motherboard and lock in by turning the knob at the top of each leg. Make sure the CPU fan is securely fastened and seated correctly onto the CPU before proceeding.

Step 2: Install Ram

Adjacent to where the CPU socket, located on your motherboard, you should see two or more slots were the RAM gets installed. Most mining motherboards use a DDR4 form factor so make sure to check beforehand that your RAM meets the motherboards required specs.

Make sure to unlock the lever if your motherboard is equipped with one before trying to insert the RAM into its slot. To know which slot to use it’s best to refer to the motherboard’s manual and see which slot is optimal for your RAM configuration. I also want to mention for this mining rig build I use a Win10 operating system, so its best to install a minimum of 8GB of RAM.

Be sure to push the RAM into the slot until you hear a click and double-check to make sure it is seated properly in the slot before proceeding.

Step 3: Install M.2 Adapter

If you’re attempting to run any ASUS z series motherboard with an 8 GPU configuration, then you need to install an M.2 adapter. This adapter makes use of the motherboards M.2 port which allows you to run an extra GPU.

Before you install the adapter, you need to install the screw posts to the motherboard.

Once the screw posts are in you can now insert the adapter into the M.2 port, and begin fastening the screws with a small glass repair screwdriver included with M.2 adapters packaging.

Make sure your M.2 adapter is evenly seated in the port before you finish tightening the screws. Also, it best to plug in the adapters SATA power cord which attaches to the power supply later.

Step 4: Mount Motherboard

Before you mount the motherboard to your mining rig frame be sure to predrill any holes you need to hold the GPUs in place and any other hardware to avoid metal shaving debris in your electrical components.

mount mother board to mining rig frame

To avoid overtightening the screws its best to use a Phillips head handheld screwdriver when mounting the motherboard to the frame. Be sure to use a screw in every corner and at least one in the middle to ensure the motherboard is appropriately secure.

Step 5: Install Power Supply

Now that we secured the motherboard to the rig’s frame we can start installing the power supply. To do this, you need the power supplies 24 pin and 8 pin power cables.

Attach the power cables end to the motherboard and then situate the power supply next to the motherboard and proceed to plug the power cables into the power supply.

Up next you need four additional 15-pin SATA cables that came with your power supply and attach them to the power supply as well.

Step 6: Install SSD

When you opened your motherboard, you may notice some extra cables in which you need to connect the SSD hard drive to the motherboard. You also need to use one of the 15-pin SATA cables connectors to power the SSD as well.

On the same 15-pin cable you can now plug in the M.2 adapter but be sure no other peripherals devices are attached to the same cable.

The rule of thumb in GPU mining is that no more than two peripherals should run on the same 15-pin SATA cable.

Step 7: Motherboard BIOS

Now its time to power the mining rig on for the first time and modify the BIOS setting inside the motherboards BIOS settings menu. You’ll need to follow your motherboards instructions for this which I’ll do my best to provide links to videos or other BIOS guides.

Links Coming Soon… If you need help drop a comment below or more than likely a quick google search for the motherboards mining bios settings can help you faster.

Step 8: Install Windows 10

Once the BIOS gets done updating, and the settings are adjusted you can now begin installing your Windows 10 operating system.

Things to note about operating systems are that there are lots to choose from when it comes to mining cryptocurrency these days.

Most are Ubuntu/Linux based operating systems however I tend to find Win10 to be more stable as mining clients tend to see better support for Win10 than any other operating system.

Installing Windows is pretty straightforward as you only need to insert the bootable drive or disk and follow along with the installation guide walkthrough.

Once Win10 is installed go ahead and check for updates and let the computer run for however long the system needs. These first batch of updates can take up to an hour or two so please be patient while the systems updates.

After the system is fully updated I like to run some window settings tweaks to disable some of the unnecessary programs running as part of the default settings inside Win10.

To do this, I use a script in which you can download through the link below and click on once downloaded to start the process. Be sure to watch the video below as it shows you step by step on how to optimize windows settings best suited for mining rig stability.

Window Setting for Mining Script

Step 9: Install GPU and PCIe Risers

Now that we have windows set up its time to power down the rig and plug in our first GPU but first we need to attach the PCIe Risers to them.

For this build, I used the generic red and blue PCIe Risers however I’ve been slowly switching all of my rigs builds over to LEEBO Risers as I find them to be of much better quality.

After you’ve attached all the risers to your GPUs, you can start plugging your first card in and mount it to the mining rig frame.

Before you turn the mining rig on it best to make sure everything is seated correctly and check all your connections one last time.

Let the computer startup for a few minutes and let the GPU drivers have a few minutes to install before attempting to start the miner. During this time you may see the screen begin to flash which is perfectly normal especially when windows are installing the GPU drivers for the first time. However, windows may not update to the latest drivers, so its best to reinstall the latest drivers from the NVIDIA DRIVERS website.

Remember to start with only plugging in one GPU at a time during this process and allow it to fully install the drivers before install another one.

Step 10: Install Mining Software and Wallet

Ok here’s where the real work begins. You need to download a wallet, and so for this guide, I recommend a Ravencoin mobile wallet, but you can use a desktop wallet as well.

While setting the wallet up, please do yourself a huge favor and write down any seed or passphrases to ensure your wallet is appropriately backed up.

Once installed obtain a copy of your wallet address so its ready for when you configure your miner.

Downloadable Ravencoin Wallets:
Raven Coin Desktop Wallet

You need to download this miner and create a folder called Ravencoin Miner on your desktop and stick the files inside the folder for now.

Downloadable Ravencoin Miner:
Raven Coin Miner Trex

This additional software is need so that we can unzip the miner files and overclock the GPUs for better performance. Go ahead and download and install these two files before you proceed.

Additional Mining Software:

MSI After Burner
7 ZIP

Step 11: Configure Miner

Now that we have everything we need installed on the mining rig we can begin setting up our first miner which is simple.

Go back to the Ravencoin miner folder you created on your desktop and right-click on the miner file you downloaded. If you have 7 zip appropriately installed, you should see an option called 7 Zip. Once you click on it be sure to select extract here to unzip the miner files inside of the Ravencoin Miner desktop folder.

You should now have several files unzip inside if the folder however if your antivirus was set off you may need to go back and disable it or rerun the windows tweaks script to ensure the antivirus software doesn’t interfere.

Inside the folder, you’ll notice there are files extensions called BAT files in which you’ll need to select one to right-click on then select the Edit option.

From here you need to delete all the text inside the BAT file and replace it with the following commands.

@echo off
:start
t-rex -a x16r -o stratum+tcp://x16r.pickaxe.pro:3636 -u YOURRAVENCOINWALLETADDRESS.YOURRIGNAME -p c=RVN -i 21
goto start

Be sure to take notice that you’ll need to edit the wallet address with your Ravencoin wallet address and make up a mining rig name like rig1 for example.

Once you have finished editing the BAT file go ahead and click save and then proceed to left double click the same BAT file inside the folder. If everything is correct, you should see your miner startup and begin mining Ravencoin.

Step 12: Ravencoin Overclock Settings

Now that you have the miner running we can proceed to begin overclocking your graphics cards, but first, you need to plug the rest of the graphics cards. Go ahead and repeat step 8 but instead of plugging one card at a time do two at a time instead.

Remember let the Mining rig run for a few minutes to allow time for the drivers to install fully. I’ve seen this process take up to 30 minutes so please be patient. Once you have all the cards and drivers installed go ahead and restart the machine before starting the Ravencoin miner.

Once you restart the rig and miner be sure to check that all 8 GPUs are running in the miner software window. If not check the device manager inside of windows to ensure all GPUs are registering.

If everything is running fine go ahead and close the miner to turn it off and open MSI Afterburner. This software allows you to control your GPU’s clock speeds which improves miner performance however pushing your cards to hard can cause you mining rig to crash, freeze, and overheat.

I have personally field-tested these settings quite extensively, and I feel as though they are very stable for my 1050ti rigs.

Ravencoin 1050ti Overclock Settings:

  • Power Limit – 74%
  • Core Clock – +75
  • Mem Clock – 0

Make sure while you’re adjusting the core and mem clock speeds also to bump up your fan’s speed as well. You want your GPUs to run no hotter than 65-70 degrees Celsius, so don’t be afraid to set an aggressive fan curve.

Step 13: Ethereum Mining and Overclock Settings

As a bonus tip, I wanted to follow up on my earlier mention about mining Eth on these cards, and so I wanted to show you how to set up Eth mining as well.

Ethereum Wallet:

BRD Wallet: https://brd.com/

Claymore Nvidia ETH Miner:

https://mega.nz/#F!O4YA2JgD!n2b4iSHQDruEsYUvTQP5_w?2sBXjCTY

For the BRD wallet, I wanted to disclose for first-time wallet users the importance of learning how to back up your wallet always. Another thing you should note is this wallet can hold several different tokens, but for this guide, you’ll want to obtain an Ethereum or Eth address.

For the Ethereum miner file go ahead and repeat the same steps as you did with the Ravencoin miner. However, the text that you copy into the BAT file is as follows.

EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal YOURETHWALLETADDRESS.YOURRIGWORKERNAME -ttli 63 -tstop 66 -tstart 60

Remember to replace the text with your ETH wallet address and worker name before you hit save.

Now you need to start up MSI Afterburner to begin overclocking the cards, but first, you need to create a profile to save your Ravencoin overclock settings inside of afterburner.

Once you save the settings, start creating a separate profile for the Ethereum overclock settings.

Ethereum 1050ti OC Settings:

  • Power Limit – 72%
  • Core Clock – +125
  • Mem Clock – +825

Make sure to hit apply before closing MSI Afterburner and then proceed to start the Ethereum miner by double left clicking on the start BAT file.

Give the miner a few minutes to connect to the pool and you hashrate should look something like this.

You can also track your mining rig stats directly from the pool or through a phone app called ether mon.

As I stated before these are just a few of the cryptocurrencies you can mine with the 1050ti 4GB series cards. The best part I like about them is their cost per hash tends to be lower than most cards which makes your mining rig ROI faster.
