your HBM memory not work. reset card and start again.

If HBM not work i have only 1300-1350 per card and i must start xmr-stak and back to srbminer. WHY? i dont now.

Doctor any idea? i reset card but  HBM not start. when i use xrm stak with this xomand HBM start normal and after this all miner work fine with HBM memory.

This option start HBM memory
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
start xmr-stak --noCPU
exit 0

if i use xmr stak with this option HBM  start OK.

after this start  HBB ON .Why ? i dont now.
with srb miner i try but never HBM start corect if not start first time.

if i use xmr stak with this otion HBM not start.
