in the epools.txt not the start.bat if you are using the start.bat you may have better results using the epools.txt and un comment the # after you edit your line for what pool etc . i have Claymore 5.1 working with Awesome miner with no issue but had to use the epools.txt file and edited the start.bat file to show
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_FORCE_64BIT_PTR 0
EthDcrMiner64.exe
for Linux it's the start.bash use this
export GPU_FORCE_64BIT_PTR="0"
export GPU_MAX_HEAP_SIZE="100"
export GPU_USE_SYNC_OBJECTS="1"
export GPU_MAX_ALLOC_PERCENT="100"
export GPU_SINGLE_ALLOC_PERCENT="100"
./ethdcrminer64
CD\Claymore for windows
EthDcrMiner64.exe or EthDcrMiner64
for linux some thing like this @ a SSH prompt.
screen bash
cd /home/Claymore
./start.bash
or to what ever you left the folder as, it works in windows or Linux.
not sure thu if that's your issue but it looks like you might be using the bat or Sh file set up wrong . again I'm not sure if this is your issue but it sounds like it might be..!!
I 'm waiting for AMD to offer better support for ubuntu 16 were it work like it does with ubuntu 15 or lower the drivers for ubuntu 16 and amd are still hard to set up just right , so I'm gonna use win 10 for now .
and EthOS is giving us all a lot of BS now no idea why . .
