How To Build an Ethereum Mining Rig at Home 2020

Ethereum (ETH) has become more appealing in 2020, with prices rising above $270. Mining has also picked up, awarding 2 ETH each 15 seconds, or 8 ETH per minute.



ETHASH STILL ACCESSIBLE TO HOME-BASED MINING RIGS


In 2020, the Ethash algorithm is still amenable to home-based mining, and it is possible to build a rig and compete for block rewards.


An Ethereum mining rig is best built using GPU. Currently, there are specialized rigs with about 200 million hashes per second. However, the Ethereum community favors a potential hard fork to disable any Ethash-optimized ASIC.


Thus, it is safer to still use GPU, which is more agile and in a cinch, can be directed at new networks. Yet, some GPUs are optimized and achieve better performance with Ethash. At-home mining necessarily uses consumer electricity, which may affect profitability. However, mining is also a risky game and in cases of rising market prices for ETH, it may have a more significant payout further down the line.

Building up sufficient hashing power is a matter of connecting more GPUs to achieve the rig’s final setup. Currently, AMD Radeon VII is the most powerful card, producing 90 MH/s, with ProgPoW reaching 30 MH/s. Combining several video cards will quickly raise the price of the rig, as the AMD Radeon VII retails for above $500.


Building a rig also requires side components, including a power supply, a CPU, LAN components, as well as a physical crate for holding and ventilating as many GPUs as desired. Experts at the EthereumMiningBot also recommend a smart power plug, to track electricity usage.

ETHEREUM MINING RIG

Essentially, an Ethereum mining rig would resemble an entire computer, a dedicated machine to avoid overloading consumer electronics. A basic Intel i3 CPU is recommended, as well as just basic 4GB RAM and a solid-state drive. Assembling the actual rig can be easier with custom-designed racks or cases, allowing the connection of six GPUs (or 540 MH/s potential).


To connect the GPUs, a motherboard with six slots and possibly an additional power button to make switching on technically easier also go into the building of an Ethereum mining rig. For more than three GPUs, a set of connectors may be needed to place the GPUs conveniently and connect them to the motherboard. Read More...
