6 GPU Ethereum Mining Rig Build Guide

Building a 6 GPU Ethereum mining rig is a fun project and a great source of passive income. This guide will help you find and assemble the best Ethereum mining hardware to build your very own Ethereum mining rig. Assembly time is about 3 hours.

6 GPU Ethereum Mining Rig Hardware Build List

Listed below are the components you will need to assemble your GPU mining rig.

1x Power Supply –  1000 Watt Power Supply – The key here is to have an efficient 1000 watt power supply that will save you over the long run in electricity costs. Look for Gold or Platinum rated (as opposed to silver or bronze). This is the industry standard for rating the efficiency of a computer’s power supply unit (PSU).

1x Motherboard/CPU Combination – What is the best motherboard for mining Ethereum?  I’ve listed below my favorite motherboard and processor combo that is compatible with 6 video cards. This is the ethereum mining motherboard that is used in large scale mining deployments. If the pros use it, you know it’s good.

If the motherboard listed above is out of stock or difficult to find, these motherboards will work equally well with the Intel G3900 Skylake processor:

6x Graphics Cards  – Nvidia GTX 1070 –   The very efficient Nvidia GTX 1070  can produce a hash rate of 30Mh/s using only 100 watts of electricity and is the best GPU for mining in 2017. It is much more power efficient than most of the AMD cards available on the market. My favorite model of this GPU is the Gigabyte GeForce GTX 1070 Windforce OC (model # GV-N1070WF2OC-8GD). It has a twin fan design and seems to run cooler than most of the other 1070 models I’ve tested, so I put this card in all the rigs I build currently. If that specific model is unavailable, any of the twin fan overclocked Gigabyte or EVGA cards work great out of the box.

1x RAM (System Memory) –  4 GB RAM – You don’t need a lot of system memory to mine ethereum effectively. 4GB is about as small as a stick of RAM comes these days, so I recommend just picking up a cheap one as long as it is DDR 4 desktop memory.

6x USB Riser Cables –  USB Riser Cables – These are to connect the 6 graphics cards to the motherboard and allow spacing between cards for heat dissipation. These are necessary when building a rig with this many GPU’s.

1x Hard Drive (SSD)  –  Solid State Drive  for installing operating system and your mining software.

1x Custom Mining Case –  I’d recommend an Open Air 6 GPU Mining Case.I’ve built several of these 6 GPU rigs for family and friends using this particular mining case works quite well for airflow and ease of building.

1x Operating System –  If you are using the Nvidia 1070 GPU’s, I recommend mining on Windows 10, since it has the best driver support for those graphics cards.

MonitorMouse and Keyboard to configure all the software settings, initially.

Assembling the Custom Ethereum Mining Hardware

  1. Un-package everything
  2. Build / assemble the Open Air 6 GPU Mining Case
  3. Install processor and RAM on motherboard
  4. Plug in all riser cables
  5. Place motherboard in custom open air mining rig case and connect motherboard PSU connector (leaving PSU unplugged from the wall of course)
  6. Plug in SATA hard drive (or optional Linux on USB stick)
  7. Connect all GPUs to riser cables and fasten them to custom case. You might need to experiment for optimal spacing to keep the cards cool.
  8. Plug in all power supply connections.
  9. Connect mouse, monitor and keyboard and an internet connection (I use a USB WiFi adapter)
  10. Check all connections once more
  11. Fire it up! Install ETH OS.
  12. Make sure fans are fully functional. Start the mining software, tweak settings for maximum hash rates and let it run!

Motherboard, Windows and Mining Software Configuration

  1. Update the motherboard to the latest BIOS using a USB thumb drive. You can find the latest BIOS for the Z170 SLI Plus motherboard here.
  2. Configure Motherboard BIOS with the following settings changes:
    • Settings > Advanced > PCI subsystem Setting: PEG 0 and PEG 1 set to Gen1
    • Above 4G Decoding (cryptocurrency mining) should be set to Enabled
    • OS settings: disable Windows 7, enable Windows 10
    • Save and reboot
  3. OS / DRIVERS / MINING Setup:
    1. Boot from Windows 10 USB install media (you can buy it pre-loaded or build your own on the Microsoft website).
    2. Install Windows 10 Pro x64
    3. Install Nvidia Drivers
    4. Install MSI Afterburner and set memory clock to 600, and power to 70. This will give you 30Mh/s per 1070 GPU
    5. Install any system drivers that didn’t auto-install (check device manager)
    6. Rename PC to mining worker name. Something like Minion001, Minion002, etc.
    7. Install Claymore Dual Miner, edit the config file with your Ethereum address and miner name. Drop a shortcut to the mining software .exe file in your system startup folder if you’d like to auto-start mining when Windows boots up. You can find the system startup folder in Windows 10 by going to: Start > Run  and entering ‘shell:startup’.
    8. Disable windows update using this guide.
    9. Set power profile to ‘always on’
    10. Install your favorite remote access software, especially if you plan to have more than one rig to manage.
    11. Fire up the mining rig and rake in those crypto coins!

Something I’ve done when building out a whole mining farm, is to do the OS/DRIVERS/MINING setup and then just clone the solid state drive using a 2 bay hard drive dock with offline clone feature built in.

Congratulations! You are now the proud operator of your very own custom built 6 GPU ethereum mining rig.

Sidenote: If mining isn’t your thing, and you are just interested in purchasing some cryptocurrency as part of your investment portfolio, I personally use and recommend Coinbase. I would also recommend keeping your coins safe using the Ledger Nano S hardware wallet, since even the best crypto exchanges can be hacked through a variety of methods.

MONERO MINING – HOW TO MINE MONERO ON WINDOWS WITH CPU & GPU

Hey, what sup ? I have seen in some places people asking about Monero and how to mine it, if you don’t know much about it, Monero is a secure, private, untraceable currency. It is open-source and freely available to all. You can read all about it right here, or watch video below.

 

Today i’m going to show you how to mine Monero coin on Windows / Linux with CPU and AMD / nVidia GPU.

AMD video cards are the perfect choice to mine Monero but i will show you examples for both AMD and nVidia cards.

Here we go! I will start mining Monero with CPU

MONERO CPU MINING

1First step is to download the miner, i will be using Claymore’s CryptoNote Windows CPU Miner v3.5download it from here , read more about the miner here2Once downloaded extract the contents in a folder and access it.3Then open “pool 32bit.bat” or “pool 64bit.bat” (depends what windows version you have) with notepad and paste the following code: “NsCpuCNMiner64 -o stratum+tcp://monerohash.com:3333 -u YOUR_WALLET_KEY_HERE -p x -t 4” , don’t forget to replace your wallet key. If you don’t have one it can be generated from your kraken.com account.4Now open the “pool 32bit.bat” or “pool 64bit.bat”, in my case ill open “pool 64bit.bat” because i have 64bit windows version. If you notice a message like “CANNOT ALLOCATE MEMORY!” and “SLOW MODE WILL BE STARTED IN 15 SECONDS…” you must do the following steps:

    1. Create shortcut for NsCpuCNMiner64.exe on desktop, you must be logged as admin aswel
    2. Open shortcut properties
    3. On “Target” location at the end of the line “C:\Users\USER\Desktop\Claymore CryptoNote CPU Miner v3.5 Beta – POOL\NsCpuCNMiner64.exe”  add this “-o stratum+tcp://monerohash.com:3333 -u YOUR_WALLET_KEY -p x -t 4“, full code line should look like this “C:\Users\oneill\Desktop\Claymore CryptoNote CPU Miner v3.5 Beta – POOL\NsCpuCNMiner64.exe” -o stratum+tcp://monerohash.com:3333 -u YOUR_WALLET_KEY -p x -t 4
    4. Then Click on “Advanced” button, check “Run as Administrator” box, apply and save modifications.
  1. Now you will have to start the miner from desktop shortcut, you will still see the same error messages, just leave the miner to run for 2-3 minutes then close it and reboot your computer.

-t 4 stands for number of threads to use while mining. I have an i7-3610QM and i can go up to 8 threads, but as i understood -t 4 is the best option.

After the restart you will notice a new message saying “FAST MODE ENABLED

5That’s it, you can check mining progress here https://monerohash.com/ at the bottom of the page add your wallet key and click “Lookup”, then it will show your mining hashrate, balance etc..

Here is mine:

MONERO NVIDIA GPU MINING

For this test i will be using my laptop, the vide card is nVidia Geforce GTX 670M 3GB.

1Will use ccminer-cryptonight (A modification of Christian Buchner’s & Christian H.’s ccminer project by tsiv for Cryptonight mining.). You can download it from https://github.com/tsiv/ccminer-cryptonight/releases2Once downloaded, extract its contents3Send a desktop shortcut of Right click of “ccminer.exe” by right clicking it and then choose “Send to” -> “Desktop4On desktop shortcut that we have just created right click on it and go to properties5In target field paste the following code -o stratum+tcp://monerohash.com:3333 -u YOUR_WALLET_KEY -p x, paste it right after “C:\Users\monero\Desktop\monero nvidia\ccminer.exe”, so the full code will look exactly like this “C:\Users\monero\Desktop\monero nvidia\ccminer.exe” -o stratum+tcp://monerohash.com:3333 -u YOUR_WALLET_KEY -p x

6Now click on “Advanced” and check the box that is saying “Run as Administrator”

7Apply and save the modification and then you can close it.8Now double click the shortcut and watch the mining starting 🙂 , done!

MONERO AMD GPU MINING

I will not be able to post my results because i don’t have a AMD GPU card to mine, i will only show you how to do it.

1Download the mining software, this time we will be using Wolf’s OpenCL XMR Miner for AMD GPUs2Extract the contents from archive3Now open “xmr.conf” file with notepad. Hold “SHIFT” button then right click on “xmr.conf” and you will see at the top a new line “Open with“, click on that and then select “Notepad

4Once xmr.conf is open in notepad look for “url” and change current pool url to “stratum+tcp://monerohash.com:3333” , then look for “user” and change the wallet key with yours.

5Now, inside the folder where you extracted the files, hold SHIFT and click on “Open command window here

6In command window we will start the miner, to do that type the following command “miner xmr.conf” and that’s it. If you get a “clCreateBuffer” error, lower your raw intensity in the xmr.conf file “rawintensity“: 1336

Make sure you adjust you proper settings to xmr.conf file and also read carefully readme file !

Have fun!

How to Calculate Mining Profitability

Are you serious about mining cryptocurrencies? If so, you need to know how to make the best use of your money and equipment. In this guide, we’ll show you how to mine your digital treasure in the most profitable way.

Obviously, the big money is going into costly bitcoin ASICs. If you are already in that position, you probably know how the process works and are intending to mine bitcoin. However, those of you on a more moderate budget are probably looking at building a GPU miner for scrypt currencies, or a buying a small ASIC machine for bitcoin or other SHA-256 currencies. In that case, you have come to the right place.

How do I start?

Choose your currency

Digital puzzleThe process of mining digital currencies involves solving complex cryptographic puzzles. By doing this, miners are providing ’proof of work’ that is rewarded with digital currency. Broadly speaking, there are two proof-of-work hashing algorithms in use today: SHA-256 and scrypt. Note that there are some lesser-used alternatives, which we will not be looking at in this guide (for example, Primecoin).

  • SHA-256
    The SHA-256 algorithm favours raw processing power. In bitcoin’s very early days, one could mine effectively with the CPUs and GPUs (graphics processing units) that you find in a normal home PC. That time has passed, however, and the difficulty level of bitcoin is so high that specialised processors known as ‘Application Specific Integrated Chips’ (ASICs) are needed to mine it. The use of such powerful processors, along with bitcoin’s exponential increase in difficulty level, have created a technological arms race, which means that even quite recently designed chips can quickly become obsolete.
  • Scrypt
    The scrypt algorithm favours greater amounts of RAM and parallel processing ability, which is why GPU-based rigs are still the way to go. Furthermore, ASICs for scrypt have yet to take off, so the difficulty level of those currencies has not been pushed up as dramatically as has been the case with bitcoin.

The right rig

shutterstock_88988593Depending on your budget and the type of currency you intend to mine, there are two ways to go when setting up your mining system:

  • DIY mining rig
    These can be built from your own PC, with as many graphics cards (ie: GPUs) as you can fit or afford. While some people may use a standard PC case, many use unusual casings, such as beer crates, which allow for increased air flow around the components. A bonus of DIY systems is that you can carry out both CPU and GPU mining at the same time (see our guide to mining altcoin).
  • ASICs
    ASICs are self-contained units (power adapters not withstanding), which come with a USB and/or Ethernet port, and are usually ready made by manufacturers. ASIC miners are usually more expensive than DIY rigs and are mostly produced in the USA, which means those of us in other parts of the world will have to spend a little extra to get them imported.

Power up

Mining rigMining requires electricity – lots of electricity. If you are building a DIY rig, you’ll be getting an ATX power supply unit (PSU) anyway, so it’s worth investing in the most efficient supply you can get.

Consider the following two cases, for example: A PSU that is guaranteed to supply 860W and is 93% efficient would actually draw 925W (860W/0.93). By contrast, a 750W power supply that is only 80% efficient would actually draw 937.5 W (750/0.8) – thus using more power, but supplying less.

When building a mining rig, you will need to take account of the power requirements of all the components you are using – especially all those graphics cards. Plus it’s a good idea to provide some excess capacity to deal with unexpected events and provide the potential to overclock your system.

ASICs, on the other hand, can do far more calculations with far less power because they are highly specialised devices. And since they ship with an appropriate power adapter, you won’t have to worry about doing all the maths to find one that is up to the task.

The mining efficiency of different systems can be compared by taking the ratio of the number of hashes it can perform in a second, divided by the power it consumes:

Hashing speed / power consumption = mining efficiency

Check your bills

After the initial expense of your rig, the essential thing you need to know to calculate your ongoing profitability is the cost of your electricity. Check with your provider, or take a look at your last bill. If the power charges add up to more then you earn, it obviously isn’t a good business model.

Pool your efforts

Rather than go it alone, it usually makes more sense to join a pool, where you combine resources with other miners. By joining a pool, you earn a share of the coins mined by all members of the pool and stand a greater chance of solving a block.

Miners earn a share of the rewards if the difficulty level of the blocks they solve is greater than the level set by the pool operator. That level is always somewhere between 1 and the difficulty level of the currency.

Problems to be aware of

Spend to earn

shutterstock_96423176Inevitably, the difficulty level of all currencies increase with time – a fact that will reduce the chances of your equipment earning coins or mining shares. As a result, it is important to start with the best equipment you can afford, in order to mine profitably over the longest period of time.

The volatility of the currency being mined also affects your long-term profitability. If the price suddenly drops, you will be faced with the choice of either selling at a low price or hanging onto your coins until their value increases. In the former case, you would have to keep mining for longer to recoup your expenditure on equipment and electricity.

Keeping cool

Mining rigWhichever way you mine, it’s a computationally intensive operation that creates lots of excess heat. Mining efficiency decreases as temperature increases, so make sure your rig has adequate ventilation and cooling. As mentioned above, this is why some mining rig builders  use beer crates rather than PC cases – to maximise airflow around their components. Even a standalone desktop fan can help to keep your kit cool.

Power problems

When building a DIY mining rig, it doesn’t make sense to save money by buying a cheap PSU. Any instability in the power supply could hit performance, or even cause a system crash that will lead to downtime, so do invest in a high-quality unit.

Avoiding downtime

If your hardware isn’t mining, you are losing money. Here are some ways to minimise downtime:

  • Get the best power supply you can afford.
  • Consider using an uninterruptible power supply (UPS), so that, if your electricity supply cuts out for a moment, it won’t affect your miner.
  • Configure your mining computer to automatically start mining on start-up, so that if the system crashes and reboots, it will automatically start mining again. (This applies to DIY rigs and computers hosting an ASIC.)

Hidden costs

Losing moneyThere are costs involved with mining, of course, like the rig and the ongoing electricity costs for starters. However, some extras are less obvious:

  • Delivery and customs
    We imported a Jalapeno ASIC miner from Butterfly Labs to the UK. The delivery cost £53 ($88), and UK customs charged £46.09 in duty (around $76). These costs are significant, and if you’re importing an item, try to work out beforehand what costs it might incur.
  • Accessories
    Will you need cables, adapters, etc, for what you are planning to use and/or build?
  • Cooling costs
    It’s not just the cost of your miner’s power use. What about the electricity of running any extra cooling system, such as fans or air conditioning?

Doing the sums

Profitability calculators

shutterstock_135890222For assistance with some of the calculations miners need to make, there are several websites that provide profitability calculators. You can input parameters such as equipment cost, hash rate, power consumption, and the current bitcoin price, to see how long it will take to pay back your investment.

As a test, we entered the specifications of two mining systems into the calculators below. For our Scrypt GPU mining rig, we used the system described, and for our SHAS-256 ASIC miner we used the specifications of a Butterfly Labs miner.

With a UK electricity price set at £0.20 per KWh (which equated to $0.33), these are the recommendations and profits that the following sites presented
