# 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 Pool address.
* -U, --user User name or wallet address used for mining.
* -p, --passwd Password used for mining.
* -d, --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.**

## Modify record:
#### v3.0(2018-06-09)
* Raise the power significantly
* Automatically optimize the last version of the `-i` parameter
* Add `-M` option to handle `CUDA out of memory error' that may occur when dealing with multiple cards
* Windows to increase the graphical interface shell program, easy to novice operation
* Add an announcement on the graphical interface to get the latest version notification
* Fix known bugs to improve stability.
#### v2.0(2018-06-04)
* Further reduce CPU usage.
* Increased acceleration mode for high-end CPUs and high PCIE bandwidth.
* Support Linux
* Fix known bugs to improve stability.
#### v1.3(2018-06-03)
* First edition.
* Supports Windows.
* Optimize CPU, PCI-E bandwidth usage.
* Optimize mining speed.
* Support standard stratum protocol.
-i parameter have been remove , but now power limit % have a lot less impact power consumption .
now it say 3% fee , yesterday on V2 i observed change in fee they occurred more often but during a significant shorter time.
