Ethereum ETH Mining Tutorial and Graphics Mining Machine Construction Guide

Preparation <br/>Recently, there are more and more discussions about ETH mining. The editor of Miningcoin.com obtained an Ethereum mining tutorial from a well-known domestic mining pool, miner, and seven-color angelfish and provided it to everyone. Fish Pool (www.f2pool.com) launched the only Ethereum mining pool in China, and recommends everyone to use it.

Ethereum mainly uses graphics cards (GPU) for mining. You need to configure a PC with multiple graphics cards to run the mining program. The main hardware includes: graphics card, motherboard, power supply, CPU, memory, hard disk (SSD with more than 60G is recommended), extension cable, adapter cable, etc. The graphics card determines the speed of mining, and the motherboard and power supply largely determine the stability of the mining machine.
Hardware preparation <br/>Motherboard recommendations: Graphics card mining does not require a large PCIE bandwidth, and a motherboard with PCI-E 1X can meet the bandwidth requirements. Generally, a motherboard has 3-5 PCI-E 1X interfaces and 1 PCI-E 16X interface. In addition, the motherboard has a large 4PIN power supply interface to improve stability. PCI-E1X requires a 1X to 16X extension cable purchased from Taobao.

Motherboard recommendation:

Graphics card: 280, 280X, 290, 380, 380x, 390; 4G or above video memory; N card GTX 950 or above;

Wallet preparation:
Get a wallet address: (wallet, trading website are both OK);
Graphical wallet: https://github.com/ethereum/mist/releases
Command line client Geth: https://github.com/ethereum/go-ethereum/releases/
Exchange (recommended):
Domestic Yunbi https://yunbi.com/
The P network with the largest trading volume is https://poloniex.com (you need to go over the firewall to get the verification code when registering)
It is recommended to register an account on Yunbi.com and then generate a recharge address
Mining Settings
1. The system and driver system is best for Win7 64-bit, and the official original system is used for construction. The latest version of the driver has a poor speed because the mining software has not been optimized. A card recommends the 15.11 version driver. Make sure to identify all graphics cards.
2. Mining software Mining software includes ethminer and Stratum Proxy. Ethminer obtains tasks in the getwork mode and performs mining. Stratum Proxy converts the getwork protocol into the Stratum protocol, connects to the mining pool, and provides a stable and fast getwork connection for the LAN mining machine. Using Stratum Proxy will reduce packet loss and latency, and provide mining pool backup settings, increasing revenue by 10-20%. Since ETH has one block every 16 seconds and the mining software is not perfect, the rejection rate through Stratum Proxy is currently 4-5%, and the getwork protocol is above 10%.

First, modify the payment address, offline alarm mailbox, mining pool address, etc. in eth-proxy.conf; run eth-proxy.exe;
Edit wakuang.bat in the ETHminer folder,
ethminer --farm-recheck 400 -G --cl-local-work 64 --cl-global-work 16384
-F http:// LAN address where the proxy (eth-proxy.exe) runs: 8080/miner number
--farm-recheck: software mandatory update task cycle unit is MS;
--cl-local-work : operation bit width, can be 64, 128, 256;
--cl-global-work: number of graphics card computing threads;
Worker number: only supports lowercase letters and numbers. The mining pool automatically adds miners. You don’t need to create a new one in the mining pool. Just double-click wakuang.bat to start mining.

Troubleshooting

2G video memory card cannot mine, add the following command in wankuang.bat:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

DAG file error is displayed. Please delete the DAG file and regenerate it. The DAG directory is in; C:\Users\username\AppData\Local\ethhash
