Crypto Mining Guide

Build Your First

Mining Rig

Contents

Introduction

Ethereum mining is an incredible way to make extra money on the side and supplement your income. This guide is going to show you how to build a professional grade multi-GPU mining rig. This is the next logical step after you’ve proven the concept with a Gaming PC.

My first guide stepped you through how to get an existing Gaming PC to start mining. This guide will show you how to scale up and add more and more GPUs

Many see crypto investing as just buy and hope, but the incredible reality is we can participate in the space and get rewarded for our contribution.

I hope you find crypto mining, and specifically mining Ethereum, to be as rewarding as I have found it to be.

This guide is offered free with no strings, no referral links, no affiliate links and no expectations of reward or compensation.

Why?

Mining crypto has been one of the best and highest returning investments of my life. I discovered it on Twitter and learned it for free by watching YouTube videos. I want to give back to the very thing that has put over $200K into my pocket in just over a year and I want you to participate too.

Start small, mine what you can, and let your imagination inspire you to what your next step will be.

Regards,

Stephen Wealthy

Goal

I approach this guide with the assumption you’ve proven that crypto mining works for you and you’ve followed my first guide. In my first guide I stepped you through how to take a Gaming PC and convert it into a small-time mining rig. In this guide, I will show you how to scale up, add additional GPU’s and build your first legitimate mining rig.

After this guide, it really is a matter of just rinse and repeat, build, and scale.

Hardware

The easiest way for me to show you how to build a mining rig is to take one of my existing ones, break it down, and show you how to build it back, install the OS, and get it back up and running again.

Here is the rig we’ll be using today as our victim.

This little rig makes 128.6 MH/s on the ETHASH algorithm.

Let’s tear it apart

Power button switch

Comes with the Veddha mining frame.

Simple button switch that we connect directly to the motherboard

2

USB drive

USB Drive to store the Mining OS

8GB or more, fast USB 3.0 is recommended

3

Motherboard

Center of everything

For this build we are using a TB250-BTC PRO. It has 12 PCI-E lanes.

4

RAM

DDR4 2400 8GB RAM

You can get away with 4GB but 8GB seems to be a great sweet spot

5

CPU

Intel Pentium G4600 processor

Anything will do – it is a misconception that a strong processor is needed. I have mining rigs with 8 GPU’s running on a simple Celeron processor.

In a manner of speaking, we just need something to fill the socket

Power Supply

Corsair HX750 750 watt power supply with platinum rated

efficiency.

7

Nvidia GTX 1060 6GB

GPU

Meets the minimum requirement of 6GB of VRAM for Ethereum mining. Produces 21.9 MH/s on 75w

8

Nvidia RTX 3070 8GB

GPU

Non-LHR card. Makes 60.3 MH/s on 117w

GPU Risers

Connect to the GPU and provide separation between the motherboard and the GPU.

These are essential to make it possible to connect multiple GPU’s

to the same motherboard.

If not for these, it would not be possible to build this rig

Misc Tools

Screws, ties, and tools for building the machine.

The Veddha Mining Frame

I absolutely love the Veddha frame. My first build ever used some off brand imitation, but after I tried a Veddha frame I was sold, and the rest of my rigs have used them. This one can hold 6 GPUs. You can also get one that holds 8.

These can be purchased off Amazon or the Veddha website.

One of the new pieces as compared to a normal PC is the open-air mining frame.

I know at first glance it seems weird to hold all the components open and exposed. However, this helps dissipate heat which prolongs the life of the entire system.

Important Component Details

I want to break down some important details on a few important components that we will be using today.

Motherboard

Bullet

Item

Description

1

Model

We will be using the TB250-BTC PRO motherboard. This is a motherboard specific to mining.

It is made to handle the demands of mining 24/7

It also has 12 PCI slots so we can attach up to 12 GPUs to it

2

Molex Power

Additional power connector

Mining motherboards will pull more power than one used for a traditional gaming or workstation computer. So, they add one or two of these so they can get more power into the board and keep it stable.

3

PCI-E x1 Slot

These are the slots we use to connect and attach the GPUs into the motherboard.

PCI-E x16 Slot

Full sized PCI-E slot. You will be familiar with these if you’re

coming from a Gaming PC.

You can insert a GPU into this too. Yes, even with one of the

smaller X1 slot connectors we’ll be using later.

1

CPU

I prefer low power Intel CPUs for my builds. This is a Pentium G4600 processor.

You can also use AMD processors too.

2

RAM

I have 8GB of RAM and it is DDR4 2400 speed. The minimum for this board to make it function.

You can see a common theme here – I want the cheapest CPU and RAM so I can put more money into the GPUs

3

CPU Power slot

This is where we will connect the power supply to the board to power the CPU.

Power Supply

Bullet

Item

Description

1

Power Supply

This is a Corsair HX 750 power supply. It can deliver a maximum of 750 watts at platinum rated efficiency. Although rated for 750 watts, it will only deliver what is needed to drive the system.

This is enough to drive the 3 GPU’s we will be building today, but larger mining rigs will require stronger power supplies.

So, if you plan on building 6-8 GPU rigs you will need 1000-1200 watts and possibly 2 power supplies.

Corsair, EVGA and Seasonic are all terrific brands.

Don’t cheap out on this as these will be running 24/7

2

24-PIN Connector

This connector goes into the motherboard

3

Molex Connectors

We need two Molex strands. One to power the fans on the frame and the other to connect to the motherboard.

4

PCI-E Cable

Powers a GPU. One strand per GPU.

5

PCI-E Cable

Powers a GPU. One strand per GPU.

6

PCI-E Cable

Powers a GPU. One strand per GPU.

7

CPU Cable

Powers the CPU

NOTE: I have no SATA power cables for this build. You will need to attach one if you intend to build your rig with an SSD. But you should never power a GPU or Riser with SATA.
Repeat: You should never power a GPU or GPU Riser with SATA.

GPU Risers

The GPU Riser connects the GPU to the Motherboard by providing a full x16 slot connector and then finishing with a x1 slot connector. This allows two things: Provide separation from the motherboard and improve cooling, and more importantly, allow us to connect multiple GPUs to the same board.

Without these we would be stuck.

You want high quality risers. I always buy mine from GPURisers.com in packs of 6. Do not cheap out on these, you will thank me later.

8

Repeat of 1-6

Same as above

PCI E Splitters

These allow us to split the end of each PCI-E express cable strand so we get 3 connectors instead of 2. We need these so we can successfully attach each GPU to one strand each.

The two on the left are of high quality and what I recommend. They are shielded with a sleeve and thicker gauge than the one on the right. Order these off Amazon, PCI Splitter, and favor the shielded ones.

I will use the lower quality connector with the GTX 1060 because it draws less power, and the thicker gauge connectors for the larger GPUs.

GPUs

Of course, we aren’t going anywhere without some GPUs. These are the workhorses of the mining rig and the purpose behind everything we are building today. Here are the GPUs we will be using and their specs.

EVGA Nvidia GTX 1060 6GB

This little guy has been with me since day one and never failed me. I did my proof of concept with this card. This one will always have a special place in my heart. I realize that means little to my readers, but just know this guy has worked day in day out and never failed me. GPUs can last and run forever.

Forever being 4-5 years

This guy produces 21.5 MH/s and consumes 75 watts. Not bad, but not great either

MSI Nvidia RTX 3070 8GB Non-LHR

This medium size guy absolutely smashes it. It is efficient and produces over 60MH/s on 117 watts. It is a gem and a rare find now.

It is Non-LHR meaning there are no limiters or restrictions on this model. It can hash at full strength.

In early to mid 2021 Nvidia put limiters in their cards to make them less attractive to miners so gamers would have a fighting chance to buy them.

Most Nvidia cards sold today (if not all) come with this LHR limiter now. It makes them less profitable for Ethereum mining – but not for other coins that use other algorithms.

Gigabyte AMD RX 6700 XT 12GB

This is one of the most rock-solid cards. I plugged it in, clocked it, and it has run problem free since day one. While it is not the most efficient, producing only 46 MH/s at 114 watts, I respect the stability and build of this GPU.

Not only that, it looks bad ass, and the LED lighting is some of the best. You’ll see it later when we finish

the build.

Start Building Base

Alright enough review of hardware – let’s get building!

Our immediate goal is to not to get the GPU’s hashing and mining, but rather to get the OS loaded and running, and to run any updates it needs. Once we have that, then we begin connecting the GPU’s.

So, we build, install, update, connect, then mine. Why do we do it like this?

This gives incremental steps so if we run into problems things are easier to troubleshoot and diagnose.

Install the Motherboard

We gently place the motherboard on top of the brass mounting bolts then begin screwing it into place. The bolts and screws come with the Vedda frame.

Install the Power Supply

Place the power supply in the designated spot on the frame and screw it into place.

At this point, we just leave all the power cables out the back. But let’s start plugging them in one by one

into the motherboard.

Note: The AC power cable to the outlet is NOT PLUGGED into the power supply.

We want to do all the connecting and plugging in without the system plugged into the wall.

Connect the Motherboard to the Power Supply

Connect the 24 Pin power to the motherboard. As it is fool proof there is only one way it will connect. Make sure it is snug and clicked into place.

CPU Power

Next, we connect the CPU power cable. This is also fool-proof and only one way for this to connect. Be sure you are using the correct cable and not a PCI-E cable strand.

Connect snug and make it clicks into place.

Connect Motherboard Molex Power

Next, we connect the additional power for the motherboard using the Molex strand

Although there are two connectors, we can use both from the same strand. You’ll notice when you

install these that they are daisy chained together and this makes it easy. Just plug them both in nice and snug.

You may want to put your finger behind the motherboard, so you don’t put undue stress on the board.

Connect Cooling Fans to Molex Power

Daisy chain the cooling fans together and then plug them into one Molex connector. If possible, use another strand separate from the one we just used for the motherboard.

Checks

This is how our motherboard looks now after we’ve connected the power.

24 Pin Motherboard

Main motherboard power connected

Your motherboard will likely be different, but this is all that is required to power this motherboard.

At this point, only the PCI Express cables are not connected.

For each strand we currently have 2 x 8 Pin connectors on the end. We want to use one strand per GPU but we need 3 ends per strand.

We will begin connecting the splitters which will give us the 3 x 8 Pin connectors we need.

Connecting a Splitter

Connect the female end of the splitter to the male end of the PCI-E strand.

Which one of the two male ends should you connect the splitter?

In the next image you will see I chose the 2nd or longer end for the splitter to connect to. This is done on purpose.

While it doesn’t matter in the end which one you pick, I find connecting to the longer end makes things easier. The shorter end will go into the GPU riser and then this longer end will reach up with the splitter and connect into the GPU.

Unless you have a specific reason otherwise, connect it as I have shown below.

Power Button

Now we just need to connect the power switch or button so we can turn on the rig

This little switch powers on the rig

You plug the other end of the switch into the mother into the power pins.

Your motherboard will specify exactly this should go. Follow those instructions. This is where I am supposed to put it for my motherboard.

After you’ve connected it just tie the button into a convenient place. It won’t be pretty, but we’re only

looking for functionality here.

Continuing Build Installing the GPUS

Now we get to the fun part.

And the most important. Here we will connect the GPUs to the risers and connect both the GPU and the riser to the PCI Express power cables. Please keep in mind the following principles:

  • We only use PCI-Express cables to power risers and GPUS
  • We do not use Molex power connectors or cables
  • We do not use SATA power connectors or cables

The reason we avoid the last two is because the power draw of modern GPU’s is so strong it can

overload the cables or connectors of the last two and start a fire.

Connect the riser board

First connect the GPU to the riser board. It can only go in one way. Push it in, but don’t force it.

Half way

All the way

Next, we connect the riser board to the PCI-E express power cable.

Power goes in the 6-pin female port

Use the connector end without the splitter

Pull back the 2-pin part

Push the male 6 pin connector into the female 6 pin connector port

Next we need to plug the power into the 6 Pin connector on the top of the GPU. This gives the card more power.

Power goes in the 6-pin port on the top of the

card

We just need one end of the splitter to plug

into this.

By now you’re getting to be an expert at plugging components into power!

Power is critical and the manner in which we do it is equally important. We need to make sure we are doing it in a safe manner so we balance the load.

IMPORTANT: GPU’s take power from both the riser and from the PCI-E ports at the top. They take 75w from the riser and the rest comes from the top. SATA and Molex cannot supply 75w reliably for long periods of time in a safe manner.

This is to say, over the long term, if you power your GPU using Molex or SATA you run the risk of fire.

I’m not trying to be an alarmist, I’m trying to keep you and your investment safe.

Please, always use PCI Express cabling to power both your GPU Riser and the GPU.

Put the GPU into place

Next, let’s bolt the GPU into place using the screws provided to us with the frame.

Nice and easy

Next we just want to tidy the cabling a bit to make sure its nice and tidy and we’re not obstructing the

airflow that will pass over the GPU

In the picture above you can see where I’ve put some zip ties and velcro straps. These will come with your GPU’s or with the frame. If you’re pressed, you can always find these at a hardware store.

All done, your GPU will look like this:

  • Securely bolted into the frame

  • Plugged into the GPU on the top using a PCI Express connection

  • Plugged into the GPU Riser on the bottom using the other end of the PCI Express cable

  • Tidy and tight and the cables are not in the way of airflow

Note, we have not yet attached the blue USB data communication cable between the GPU riser and the motherboard. That is coming.

Rinse and Repeat

Repeat the above steps with the other GPUs. Only this time we will need to use both ends of the splitter.

The next two GPUs will look like this once they are installed

And then if I step back and show you with the three all lined up they look like this

If you have any questions or concerns up to this point please reach me on Twitter @StephenWealthy_

Please be aware, I will never encourage you to send me money or invite you to enter a pool. That is a scam. I am here to help you get mining full stop. Never send me money.

USB Riser Cables

Last, we install the USB communication cables from the GPU risers but leave them disconnected from the motherboard. Watch what we do here.

Clip in the PCI x1 connector to one end of the

cable. Doesn’t matter which end.

You’ll know once it is fully connected

Repeat for your all your GPUs

Next, we connect the other end of the USB into the GPU Riser

Easily push the other end into the open USB port

on the GPU Riser

Repeat for all your GPUs

Lastly, and importantly at this time, leave the ends disconnected from the motherboard. We will connect these when we are ready

Create the OS Disk

Now we begin the task of building our OS disk. This is the drive that will hold our mining operating system and run the mining algorithm software. As critical as this all sounds, it is also incredibly simple and requires just a fast 8GB or higher USB flash disk.

As an overview, here is what we’re about to do on a separate Windows or Mac laptop or desktop computer:

  • Create an account on Hive OS

  • Down the Hive OS image

  • Write the image to the USB File

Why Hive OS? You set us up on NiceHash in your first guide!

I know, but for a dedicated mining rig nothing beats Hive OS. It is rock solid stable and allows us great flexibility to manage the over clocks and settings for the GPUs. On top of this, it also gives us the opportunity to mine Ethereum straight from a pool and to get paid in Ethereum.

Also, as you grow and add additional rigs to your setup, you can easily scale with Hive OS and grow.

Lastly, the profit margins are always better on Hive OS as compared to Nicehash so you will make more money over the long term with Hive OS.

Create an Account

Go to the website https://hiveos.farm/ <- Please double check the URL and ensure it hasn’t been lifted

or spoofed. It should not include any referral or affiliate link.

Create account

Confirm email

After you log in you will see a screen like this:

You will likely only ever have one farm. A farm is a collection of rigs, and we are just building one rig here today.

Are you wondering what I’m talking about? Yes, that’s how professional grade this software is! You can manage multiple mining FARMS and each farm can manage hundreds of RIGS and each rig can have 6-8, sometimes even 12 GPUS!

For our immediate purpose, we will only need one farm, the default one they gave you and so just go

ahead and click on it. We’re going to dive in and setup our first rig.

Click on “+ Add Rig”

Next, we want to tell it that we intend to install Hive OS onto our rig drive. Our rig drive is that USB drive.

I know your instinct is to click Windows or Mac, but we want to install Linux.

Download the latest .img file to your machine. This is an image file which contains the entire OS. We will then burn this to the USB disk.

While this is downloading in the background, click next so we can grab the software we need to burn this image.

Balena Etcher is the software we will download and install to write the image.

Download the correct version for your operating system

At this point you should have downloaded the Hive OS image and installed Balena Etcher. Now put your USB disk into your PC and launch Balena Etcher.

Let’s flash the image onto the disk.

Click Flash from file

Find the image that you’ve downloaded and select it

Select your target drive

Then flash it!

Depending on the speed of the drive it can take a while. After it writes the drive it will verify the drive and validate it.

Here is the drive being flashed from on my Windows laptop with the rig in the background.

After we have completed the flashing process, now we need to drop the config file onto the drive.

This will tell the mining rig it belongs to your account. Just drag the file to onto your drive from your download folder after clicking the download button shown below.

If you don’t see your drive in the OS, you may need to disconnect the drive and then reconnect it.

Download the rig.conf file

After download, move the file onto the

USB disk

After you’re all done, you will see the above screen. While it says we want to plug in the drive and get rolling with your mining rig which we have built so far, we don’t want to connect it just yet.

Configuring the Motherboard

We are now at the point where we want to boot the machine for the first time. This is exciting!

Our immediate goal now is to boot the machine and change some BIOS settings for the motherboard. Checklist before we hit the power:

  • Power plug connected into AC outlet and power supply.

  • All power cables from power supply to motherboard are connected as illustrated earlier

    • 24 Pin cable

    • CPU cable

    • Molex cables as required

  • Keyboard, monitor are connected to the motherboard

  • Network cable connected

  • No drive connected to the motherboard

  • No GPU connected to the motherboard (though they are connected to power)

Power it on!

You should arrive in the BIOS screen. This is a very good sign, and it means things are working as we expected.

Now, this is where things get a bit tricky because there are different settings for every motherboard. So, you actually might need to Google your specific motherboard with

“[MOTHERBOARD TYPE AND BRAND] mining crypto settings” to get the optimal settings.

However, I will step you through some universal must haves that are common across all mining boards

or gaming PC’s

Boot:

Fast boot: disabled

CSM Support: disabled

Boot sequence shouldn’t matter because we’re going to just use one USB drive.

But if you find you need to, you may need to tell the board to boot off the USB.

Internal Graphics:

Internal Graphics: Enabled

Primary Display: IGFX – this tells it we want to use the internal or integrated graphics and not the GPUs

PCI-E Lane Speeds

PCIe Speed: set these to Gen 1

Now, this will look different on your board, but anywhere it talks about PCI Express Lane speed, you want to set that to Gen 1 or Level 1.

Mining Mode

Mining Mode: Enabled

This will also look very different for your board. But if you have a setting called 4G Decoding, you want to enable this. This is critical to allow the machine to address and work with multiple GPUs.

You may also have a setting for Restore AC Power Loss”, you should enable this. This makes it so the

machine will resume mining automatically in the event of a power loss.

CPU Settings

There are various CPU settings, and this is how I have mine set for virtualization and hyper-threading. That is it!

If you have any questions or problems, please reach out to me on Twitter. I am just a DM away.

First Boot

Now shut off the machine, plug in the USB disk and power it back on.

What you will see on first boot

Seriously at this point, pat yourself on the back. We got the OS loaded and running, the mining rig is communicating and now we just need to update things and get it ready to start mining.

As this is a Linux based operating system we need to know some commands. You will want to bookmark this page for future reference: Hive OS Commands

Update OS

Before we run the update. We want to make sure it says Flightsheet Empty. This is a good sign. We want this at this point. We will address this error after we do the updates.

We need to update Hive OS to the latest version. We do this by running the ‘selfupgrade’ command

After we finish the updates, we need to make sure we have the latest Nvidia drivers installed. This is

easily done by running the command nvidia-driver-update

Now that we have the latest version installed, run the command ‘sreboot && shutdown’ This will shut the machine down. I know in the screenshot it only has one &. You need two. My mistake when I was taking the photo.

It’s time to connect a GPU and get this mining!

Connecting the GPUS

With the power off, go ahead and put one of the PCI-E x1 slot connectors in. There is only one way these go in.

I’ve zoomed in close so you can see what it looks like. I’m not sure if its superstition or reason, but I always avoid the x16 slot. (that’s the big one). I know it’s compatible and possible, but for a multi-GPU rig, I like to avoid that slot.

Now turn it back on

We want the OS to recognize the GPU, and load the drivers but complain that we don’t have a

Flightsheet set for this rig.

It is ready to start mining. We just need to jump back on the laptop and set a Flightsheet for this rig.

Building your first Flightsheet

On your laptop or PC (separate from the mining rig), login to Hive OS and you should see your new mining Rig linked to your farm.

Click on Flightsheets and you will be prompted to create a Flightsheet

What is a Flightsheet?

A Flightsheet is a concept unique to Hive OS which tells the mining operation system 4 important things

  • Coin you want to mine

  • Wallet you want them to deposit the coins into

  • Pool to want to mine with

  • Miner software you want to run

Coin

We want to pick ETH so we are mining Ethereum. Here you will also see a lot of other coins you can mine. We will need these once Ethereum goes proof of stake in 2022.

Wallet

This is where we select the wallet we want the coins deposited into.

For Ethereum mining, we need to have an ERC-20 compatible wallet to receive the mined coin. You will also need to configure your wallet in Hive OS under the wallet section. It is very easy to do, but due to sensitivity and security, I want you to figure that part out on your own.

Any Ethereum ERC-20 wallet will do. This means most Crypto exchanges, MetaMask, Ledger, or equivalent will do. Just make sure they are ERC-20 compatible.

Once you have mined 0.1 ETH, it will automatically get deposited into this wallet!

Pool

I love the Hive ON pool. The rewards and payment structure are great, and you don’t pay gas fees on payments. The only downside is you must mine 0.1 ETH before you get paid. This can take a while for some miners. Perhaps a month or two. Some mining pools have lower requirements, but Hive On pool has fantastic rewards and payments and I’ve used them since the day I’ve mined. I’ve tried other pools, but I have not been as impressed.

Again, the only downside is the minimum amount for a payout.

Because I live in Canada, I use their Canada pool. Choose the one closest to you.

Miner

Next, we pick the miner software we want to execute. If Hive OS is the operating system, this is the application that runs on top to run the mining algorithm. For Nvidia cards, like the 1060 we are getting off the ground, I highly recommend T-Rex Miner. It is incredibly efficient. However it only works for Nvidia cards.

For the AMD card we have installed, we will need to run TeamRedMiner but we will add that later.

Name it

After we have set up the Flightsheet, give it a name and save it.

Now go back to the Mining Rig or “worker” in Hive OS and click Flight Sheet

Then find your newly created flight sheet and click on the rocket

Now check this out, go over to your rig and watch the monitor It will immediately pick up the sheet and begin mining!

Quickly go over to rig and type in the command motd watch

This opens a window for us to watch the miner software run

There it is!

Now look back at your laptop and you’ll see something like this!

Now we just need to plug in the other GPUs

So hit escape button on the mining rig and input the command sreboot && shutdown again and unplug the machine

Then plug in the next card – I put in the Nvidia 3070 next. After it is in, I just boot the machine again.

See that at the bottom, where it detects 2 Nvidia drivers?

We’re in business.

The system should automatically detect the card, and when it begins running T-Rex miner, it will automatically start mining with it too.

The only thing I did here was connect that GPU – that is it. No other settings or configurations are required. The system is smart enough to detect all available GPUs and begin mining with them.

To add the last GPU, the AMD 6700 XT, we need to do a couple extra things to get it to mine with AMD. So shut down the system using sreboot && shutdown command again and plug in that last connector

Next, before we power it back on, we need to go back and update the Flightsheet so we can drive the AMD GPU.

We do everything the same. Same coin, wallet and pool. Just this time we select TeamRedMiner as the miner software we want to run. The mining rig will now run both at the same time.

Save by hitting update

Then let’s power up the mining rig.

This is what we want to see – it detected all 3 GPUs. 2 Nvidia, 1 AMD.

If it doesn’t load the miner monitor, then type motd watch

You will have 2 miner applications running. Type ‘1’ for T-Rex, Type ‘2’ for TeamRedMiner. Here we can see both are running!

This is exactly what we wanted.

Now let’s go back to Hive OS and double check things

Absolutely exactly what we want to see – we are mining and all 3 cards are working.

Setting the Overclocks

Next, we need to set the overclocks. We do this by overriding the default settings for how fast the GPU core and memory work and then limiting the power consumption. This is one of the benefits of Hive OS over Nicehash – we get a lot of control and customization.

By setting how fast the GPU’s work, and limiting their power consumption, we can actually make them mine more efficiently which means more money in our pockets.

In the screenshot you see above, those are the default settings with nothing configured. Note the

power and how much hashrate we’re generating.

Now click that top right gauge that I have highlighted in red.

**NOTE** You need to be conservative and reasonable with what you can expect from each GPU. You should also research what you should set for each of your GPUs from trusted sites. Here are the settings for the 6700 XT

Here I set how fast I want the GPU core to think, the memory to work and I leave the core voltage alone. I save, and then I adjust the settings for the Nvidia cards as well.

After I have set my overclocks and let the system settle, look how I’ve increased my hashrate while

decreasing the power consumption

Every card is producing more MH/s while consuming less electricity. Yes, you should definitely overclock each and every card.

Also note that the heat being produced by each card has dropped or stayed the same. This is critical for 24/7 operation and prolongs the life of the card.

Fan settings

Keeping your GPUs cool and in an optimal operating temperature is critical. You don’t want them

running over 80% for extended periods of time.

Here are the fan settings I have enabled for this mining rig. These are easily access from your laptop in the top corner.

All of my rigs more or less have these same settings. You can also play around with Smart mode if you

think that will help too. Some of my rigs have it enabled, while others don’t. In any case, just copy what I have here until you want to fine tweak it later.

Hashrate Watchdog

Another setting that is very useful is to enable Hashrate Watchdog. What this does is Hive OS will watch and monitor the hashrate for your mining rig. If for some reason it drops below a threshold you specify, it will restart the mining software. If that doesn’t fix it, it will reboot the system.

While this doesn’t happen often, you will be surprised at how often this automated reboot will fix any

issue that arises.

Just set it 5-10 MH/s below your normal average rate.

Monitor from your Smartphone

On top of all this, and also being free until you have more than 3 rigs, Hive OS can also be run and managed from your phone.

This makes remote control and management much easier

There isn’t much I can’t do from my phone. It is a simple download from your respective app store and authentication.

On the topic of authentication, be sure to enable multi-factor authentication for your Hive OS account too.

Payouts & Getting Paid

It’s the common question – how when and how much do I get paid?

At the time of writing this guide – December 29th, 2021, here are my recent payouts.

Notice how I get paid just over 0.10 ETH? Notice how they happen at about the same time in the morning?

That’s because with the pool I mine they pay at midnight once I have mined a total of 0.10 ETH or greater. Currently, it takes about 4 days for me to mine 0.10 ETH and then that gets paid into my Ethereum wallet at midnight.

I can do it as I please after I get payment. I don’t pay fees and its paid out automatically once I meet the minimum threshold.

Now keep in mind this is straight native Ethereum we are getting paid!

I’ll repeat that one more time… we’re getting the straight good here. Ethereum. There is no conversion or synthetic derivative here. This is the legit coin we are mining and we get paid as such.

Here is the finished Rig

Airflow

Always have adequate airflow moving across and over the mining rig. This allows for the heated air and waste energy that it produces to leave the system. If you do not take care to ensure the system adequately cools, the mining rig will produce rejected shares or worse damage itself.

This doesn’t need to be complicated. A simple pedestal fan can help. Also make sure you done obstruct or restrict airflow.

Electrical Breakers and AMPS

A prevailing concern through this guide is that you properly power and connect the GPU’s to the power supply. This is of critical importance. I stressed time and again that you do not use SATA or Molex cables to power your risers or GPUs.

On top of this, be aware of how much electrical power you are pulling for your mining rig.

  • One mining rig per electrical breaker in your house or location

  • 1100-1200 watts maximum per rig

    • I always stress the importance of 6-8 GPU’s per rig. No more.

  • Watch your mining rig and breaker for the first few days after you get it up and running

  • I monitor mine twice a day. Once in the morning and once in the evening before bead

A goal with GPU mining is to spread the electrical load across as many circuits and breakers as needed to keep things safe.

Done safely, GPU mining is perfectly safe and you won’t damage your equipment or property.

Closing Thoughts

Ethereum mining is one of the best investments I’ve made in my life. I know this sounds like cliché marketing, but as a case in point: I shared a guide here for how you can get into this and I didn’t charge you a thing.

I didn’t even ask for your email.

This is my way of giving gratitude for the best thing that’s happened to me. It’s difficult to describe.

Please follow this guide, let inspiration guide your next step, and reach for the sky.

I am always available on Twitter @StephenWealthy_, and I am here to help you diagnose problems as you go.

Common Questions

How much electricity does this consume?

Computers are surprisingly energy efficient. A lot of work has gone into making them this way with advancements in chips and power modulation.

That being said, the test rig I’ve shown you will consume 426 watts from the wall. What I mean by that is if we hook up a watt meter and measure it, it will pull 426w. This is the most accurate measurement of how much power this computer pulls.

Now, take that and divide it by a kilowatt hour, and then multiple it by your electrical rate. My rate here is $0.10 a kilowatt hour so this will cost me $30.53 to run non-stop for a month.

Now keep in mind this is going to generate us $8-12.00 a day. Not a bad trade off.

How can I get more GPUs

Yes, current supply shortages and sky-high demand are making it very difficult to get GPUs. If you can’t find a good deal online, my recommendation is to go into your local retailer and buy any if they have some in stock.

If they don’t have any in stock, then put your name on a waitlist.

My favorite brands are EVGA and ASUS, and I like the top-of-the-line ASUS Strix and EVGA FTW3 models. They stay cooler and run a bit more efficient.

Am I going to wear out my GPUs or computer?

While it is true we are running the machine 24×7 we are also running the hardware at about 60- 70% of the limit. The overclocks we set help to keep them cool and running efficient. We are not pushing them hard.

These GPUs are expected to last 4-5 years even with operating non-stop every day. It is actually more likely they will become uneconomical for mining before wearing themselves out.

Cooling and long-term running of your machine

Make sure you have adequate airflow over the machine so the computer can stay cool and

operate within spec. They don’t like it too hot or too cold. Try to aim for 27-32 degrees Celsius or 80-90 degrees Fahrenheit.

With Ethereum moving to POS why start mining now?

It is true that Ethereum is moving to proof-of-stake and proof of work mining will be shut off for this incredibly profitable coin. But there will always be another coin to mine and NiceHash will always ensure you’re always mining the most profitable one.

On top of this, you have the opportunity to learn how crypto mining works with a PC that you’ve

already bought. When the prices for mining hardware come down next year when the other miners FOMO’d in and want their money back, you have the experience and know how to mine crypto.

Learn to mine today, then prey tomorrow.

Why are you sharing this for free?

Ethereum mining has been one of the best investments I’ve ever made. It has put more money in my pocket than any other single investment I’ve made. It has been tremendous, and I want to give back to that very same community. This is my contribution to the decentralization of money, and the power it can give. Ethereum is the best and I want to give a bit to this project and help in my small way.

There is no scam here. I don’t want your wallet address, and I’m not asking for anything in

return. I want you to be involved with crypto and I want you to make money off it.

This is just my way of giving back to the very thing has been an incredible blessing and wealth builder for me.

How can I give back to you?

First, follow me on Twitter. I value network and social media a lot. So, following me on twitter is a big vote of confidence for me. If you already follow me, thank-you.

Next, after you’ve been mining for a while, post a picture of your rig and tag me. I want to share in your success.
