Ethereum mining is the process of reaching a consensus on all the transaction occurring on Ethereum network.

Ensuring security and permanency of each transaction carried out on the network are some key advantages of an Ethereum mining rig. Other features of sending Ether to lock in changes for the applications (app) and execution of smart contracts can also be utilized.

But where does the revenue flow in?

The answer to your question is that you are rewarded for joining your mining network to increase the overall hash rate of the system when you build an Ethereum mining rig.

Depending on the mining ‘difficulty’ and the current value for Ethereum cryptocurrency, the amount awarded to you may vary. Many people often convert the awarded mines to USD Dollars for better revenue margin. As an example, a person makes $500/month (with current trends of early 2018) with the rig by following this guide.

So, be wise and choose the perfect guide for building your mining rig before entering the cryptocurrency world.

    miner project. Create a shortcut to the mining software .exe file in the startup folder of your system. To
    enable auto-start of mining once the Windows boots up navigate to the system startup folder from this
    path: Start > Run and enter ‘shell:startup.’
  8. Using this guide disable the Windows automatic update and set the power profile to ‘Always On.’
  9. Install a remote access software, if you are planning on managing more than one rig to manage all the
    rigs remotely.
  10. Start the mining rig and earn those crypto-coins

BIOS Settings for Motherboard

Tweak the BIOS settings of your motherboard for optimal performance. This can be achieved by turning off the unneeded services on the BIOS, keeping all the PCI settings automatic, setting up the graphics TOLUD to 3.5GB.

The power should be supplied only when the power is on.

Setting up Mining OS EthosDistro

If Windows isn’t your thing then, Linux is the best option for setting up your mining operating system.

EthosDistro is a purposefully built version of Linux optimized for GPU mining. As opposed to Windows and Ubuntu, this operating system is recommended by various experts for GPU mining.

With EthosDistro, you don’t need to mess with the operating system and actually save a lot of time. Of course, using the same hardware build with Windows or Linux is all the same and doesn’t affect much. However, it is recommended to use a purposefully built operating system.

The best part about EthosDistro is that it has settings for adjusting power, the fans, core clock speed, and memory clock speed. Thus, allowing you to overclock and limit the power of the GPU’s.

Moreover, you can also set up one single configuration file on the web server. On changing that one file on your miner project, you can go to that configuration file on boot network, pull up the config and simply start mining. Furthermore, it also checks if the file when it is running every few minutes, hence, it is possible to reboot the miner to have it accept the changes and the new settings.

Once you are done setting up the BIOS, connect to the WiFi and reboot the Ethereum mining rig. You will see the bootup screen of EthosDistro which is simply user-friendly with a command line. Thus, you are successfully running the Ethereum mining rig.

But there are some critical pieces of information you need on this screen.

IP address: which can be accessed by SSH – this one is at 10.172.0.232

Name: For our screen it is e7423e

URL of the statistics website which depends on your location and IP address: for us it is

http://a127f5.ethosdistro.com

Change the EthosDistro mining address by using the SSH from your PC rather than the bootup screen. The commands differ for the different operating system.

Use the below set of command to change the address.

For Linux – You must use the Terminal command line
For Mac – You must use the Terminal command line
For Windows – You can use the Bash command line or Putty

Setting up EthosDistro to Mine

Find the IP Address on the screen:

ssh [email protected]

(enter password live)

The Ethereum system is designed to download and run a file from the web. If you plan to change it, you can edit remote.conf with nano or VIM, making it a blank file.

Once done as soon as the system boots, it will copy the file which is referenced in the Remote.Conf into Local.Conf provided the Remote.Conf file holds nothing and is void.

Depending on a single miner or more, you must edit the local.conf file with nano or vim for configuring the miner. Here is an example of configuring the miner for Zcash. Place the below piece of commands at the beginning of the local.conf file.

globalminer ethminer

maxgputemp 90

stratumproxy enabled

flags — cl-global- work 8192 — farm-recheck 200

globalfan 85

#mem 4288a0 4314 4314 4314 4314 4314 4314

Always keep the configurations for multiple mining pools in the file only. They must, however, be commented out with the # symbol.

Thus, allowing you to change what you are mining by just altering the configuration without any additional efforts. Another important fact to note before you start mining is that you definitely want to have a wallet address on your mine. This can be set by proxywallet configuration item.

It always preferred to use a softer wallet for all the Bitcoin-based cryptocurrencies, like ZEC and ZEN. You can then transfer the cryptocurrencies to your hardware wallet on a periodical basis such as week or fortnight. Currently it possible mine to a hardware wallet for ETH, ETC, and ZEC. Mining to a software wallet is available for ZEN.

If you are mining to a hardware wallet or exchange, it is preferable to change your pool settings so that deposits are made only once a day. The frequency of deposits in your hardware wallet or exchange more than once a day can cause unnecessary issues and thus, should be avoided. Moreover, don’t forget to perform periodic maintenance of your wallet.

As soon as you get the miner up and running with 1 GPU, you can get it running on 6 GPU’s as well with ease and simplicity. However, it is preferable to plug them in one at a time and reboot simultaneously, to figure out any errors in terms of risers, cards or anything else.

Tune up the GPU’s for Maximum Performance

For maximum performance, it is an excellent idea to tuning up the power settings of each GPU. The maximum power of each GPU’s is 200 watts. Tune up the power setting of the GPU’s to 160 watts as statistics suggest that it works the best.

Later on, work to increase the memory speed of the GPU’s as much as possible. In the case of the ASUS Strix, it is possible to raise the memory speed up to 3802 to 4360 from the default.

When you are operating the EthosDistro OS, it will turn the GPU processor speed down. Hence, the card remains within power limits.

Earnings of a GPU Miner

Usually, people build Ethereum mining rig on one cryptocurrency and leave it for mining for a month or two. Since it preferred to mine and hold, we suggest that you mine a cryptocurrency involving less competition.

Meanwhile, some people do not believe in the concept of mine and hold. Instead, they prefer to mine and sell to earn cryptocurrency rewards from what they mine.

If earning is your then you must earn rewards by selling whatever you mine as it offers more earnings then in mine and holds policy. However, both the fundamentals are profitable with the only difference being your preferences.

Conclusion

GPU miners are not only fun to build but are also profitable thus, garnering more audience. The Ethereum mining rigs are straight-forward to build and are equally flexible and cost-effective. Depending on your budget you can start small by building single GPU mining rigs and add more GPU’s as you earn more.

For most people planning to enter the mining area, it is always preferred to start mining with just one GPU mining rig. The reason for that being, the learning experience associated with it.

As you can proper knowledge and expertise on building multiple GPU mining rigs you can proceed further and earn more.

Thus, building a 6 GPU Ethereum mining rig is simple and filled with rewards.
