setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100
@echo off
cd %~dp0
cls
SETLOCAL EnableExtensions
set EXE=bxb-miner.exe
:START
FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto RUNNING
%EXE% -c config_lite_v7.json
TIMEOUT /T 15 /NOBREAK
goto START
:RUNNING
echo "%EXE% is already running"
pause
setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100
@echo off
cd %~dp0
cls
SETLOCAL EnableExtensions
set EXE=bxb-miner.exe
