### XMR-Stak-AMD - Monero mining software

XMR-Stak is a universal Stratum pool miner. This is the AMD version.

#### Usage on Windows 
1) Edit the config.txt file to enter your pool login and password. 
2) Double click the exe file. 

XMR-Stak should compile on any C++11 compliant compiler. Windows compiler is assumed to be MSVC 2015 CE. MSVC build environment is not vendored.

#### Usage on Linux
```
    sudo apt-get install ocl-icd-opencl-dev
    sudo apt-get install libmicrohttpd-dev
    cmake .
    make
```

GCC version 5.1 or higher is required for full C++11 support. CMake release compile scripts, as well as CodeBlocks build environment for debug builds is included.

To do a static build for a system without gcc 5.1+
```
    cmake -DCMAKE_BUILD_TYPE=STATIC
    make
```
Note - cmake caches variables, so if you want to do a dynamic build later you need to specify '-DCMAKE_BUILD_TYPE=RELEASE'

#### CPU mining performance 

Performance is nearly identical to the closed source paid miners. Here are some numbers:

* **I7-2600K** - 266 H/s
* **I7-6700** - 276 H/s (with a separate GPU miner)
* **Dual X5650** - 466 H/s (depends on NUMA)
* **Dual E5640** - 365 H/s (same as above)

#### Default dev donation
By default the miner will donate 1% of the hashpower (1 minute in 100 minutes) to my pool. If you want to change that, edit **donate-level.h** before you build the binaries.
