### Increase Memory Pool
By setting the following environment variables before the miner is started OpenCl allows the miner to more threads.
This variables must be set each time before the miner is started else it could be that the miner can not allocate enough memory and is crashing.
```
export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=99
export GPU_MAX_ALLOC_PERCENT=99
export GPU_SINGLE_ALLOC_PERCENT=99
```
*Note:* Windows user must use `set` instead of `export` to define an environment variable.
