# BTM GPU Mining Software (NebuTech BTMiner)

BTM (better than the original chain) mining software for Nvidia graphics cards.

## download link

[Download from here] (https://github.com/NebuTech/BTMiner_NebuTech/releases)

## Features:

* Supports Windows, Linux (Tested on Ubuntu 16.04)
* **Windows GUI operation**
* Mine pools supporting the standard stratum protocol, tested: [f2pool] (https://www.f2pool.com/), [antpool] (https://www.antpool.com/), [btcc] (https: //pool.btcc.com/)
* Almost no CPU and PCI-E bandwidth, available for existing 6 or 8 card mining machines
* Optional CPU-accelerated mode to further increase the computing power on machines with high-end CPU and high PCIE bandwidth

## Instructions:

1. **Updated to the latest version of the Nvidia graphics driver. Older drivers are not supported. (Driver version needs to be greater than or equal to 396)**
2. ** Double-click on `GUI_Wrapper.exe` to open the Windows GUI and start mining. **
2. Use Notepad to open the `Windows.bat` file (Linux system changes `Linux.sh`), modify the pool address after `-url` and the wallet address or user name after `-user`. If you have a password, add the `-p` parameter and password.
3. Double-click on Windows.bat to start mining. Linux starts mining on the command line with `Linux.sh`.

## command line arguments:

BTMiner_NebuTech.exe [arguments]

Typical usage: BTMiner_NebuTech.exe -url btm.f2pool.com:9221 -user bm1xxxxxxxxxxxx.rigName -p x

parameter:

  * -?, -h, --help Displays help information.
  * -v, --version Displays the version number.
  * -u, --url <url> Pool address.
  * -U, --user <user> User name or wallet address used for mining.
  * -p, --passwd <password> Password used for mining.
  * -d, --devices <devices> Specifies which graphics cards to use for mining. For example: "-d 0,1,2,3" Use the first 4 graphics cards.
  * **-C, --use-cpu Use this option to enable CPU acceleration mode. If you have a powerful CPU and a graphics card plugged into a PCI-E x16 slot, try turning this option on to further increase your computing power.**
  * **-M, --more-gpu Use this option to avoid "cuda out of memory error" and there may be a small amount of power loss.**
