midasminer_u50c

Introduction

FPGA bitstream is a file that contains the programming information for the FPGA chip. midasminer_u50c is our specific bitstream for FPGA to behave as a miner. U50c with HBM can mine Ethereum faster because HBM allows the accelerators to perform memory-hard compute tasks much faster than existing technology.

Features

1. The hashrate could be up to 56 MH/s.
2. Mining process will automatically be disabled when temperature is over 75c and will be restarted to mine when temperature is under 60c.

Installation

The only thing you need to install is FTDI driver, which is a software driver for converting RS-232 or TTL serial transmission to and from USB signals. You can search for it on the website and download it for free. Download here:

Config Setting

In the folder, find MinerHost.exe-conf.json and open it.

What you must change:

1. You need to change line_3’s URL to the f2pool server closest to your region.

For example: "url": "stratum+tcp://eth.f2pool.com:6688", SSL was not supported currently.

2. You need to change line_4’s User_Wallet to your own wallet.

For example: "user": "0xabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd",

What you can change:

1. You can change line_5 to decide which bitstream you want to use.
2. You can change line_6 to decide your worker’s name.
3. You can change line_7 to change hashrate.
4. You can change line_8 to decide whether to create a log file in folder log or not.

Start Mining

Find MinerHost.exe and execute it in the folder.

FPGA initialization may take around 10 minutes.

After initialization completion, the FPGA will connect with the pool. The command window will display the total share number accepted by the pool.

Keep mining with U50c!

Notes

• U50c USB interface does not support PCIe-USB expansion cards.
• One single computer can hold up to 16 U50c devices.
• This beta version of the bitstream will stop mining when epoch number reaches 465. We will provide an updated version afterwards.
