i manage to fix it. i have 7 RX 580, initially it was 16mb. some GPU's are hashing 0 so after few experiments. i noticed that after i changed my virtual memory to 20mb only 2 GPU's left with 0 hash. so i change it again to 30mb.
i mined ETN november then shifted to ELLA december...
sold ella @4USD. i mined it at .5 Cents not bad.20mb? try to change it to 16GB
Read from the first post
"For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:"
oops my mistake. 20GB = 20000MB my bad. sorry...
