CGMiner Screen Output Explained

About a year ago, I recorded a screen grab of CGMiner mining Bitcoin using a single GekkoScience Compac-2 USB Mining Stick on a Windows 7 AMD Dual Core (8GB) Laptop.

The video has been watch a few thousand times, but it’s getting quite a lot of negative feedback because in the video, I play background music instead of talking about the actual CGMiner output which is what most viewers are looking for, an explanation of the data on the screen.

Even though I thoroughly go through the setup process and explain the output screen in details, the video is still generating flame among viewers, including negative comments in this blog.

So, I’m having another go at this post and this time, I’m including detailed information about the data found in the CGMiner output screen in hope to shed some light on the mining software, and to help those who are interested in mining Bitcoin using CGMiner.

As of 2018, and the latest release (version 4.10.0), CGMiner output various data based on the device(s) used. In most cases, the following data is displayed within the output screen:

The first line includes the version of CGMiner and the date/time it was launched.

The next four lines of date indicate the following:

(5s): Average Hash Rate For Last 5 Seconds
(1m): Average Hash Rate For Last 1 Minute
(5m): Average Hash Rate For Last 5 Minutes
(15m): Average Hash Rate For Last 15 Minutes
(avg): Average Hash Rate Since CGMiner Was Launched

A: Number Of Shares You Mined Accepted By The Pool
R: Number Of Shares You Mined Rejected By The Pool
HW: Your Hardware Errors
WU: Work Utility – Average Number Of Shares You Mined Per Minute

Connected to (The Pool your are contributing to as a miner)
diff (Your device’s Difficulty Setting – Preset By you and/or Adjusted by your Pool)
with stratum as user (Your pool username)

Block: Your Pool’s Bitcoin Mining ID
Diff: Your Pool’s Difficulty Setting
Started: Time Your Device(s) Started Mining Bitcoin
Best share: Size Of The Largest Share Your Device(s) Mined

The next line includes the Options Menu.

This takes us to the final static line of data features each device(s) mining type, ID, clockrate, Hardware Errors, Current Hash Rate, Average Hash Rate and Work Utility.
