I am really puzzled by this: On SMOS and HiveOS half of my 8 gb R9 390 hawaii cards are not woking. The same is with lolminer. BUT Claymore works well with 30 Mh/s (moded voltage but not vram timings). May be this is related to the kernel of linux - I know that after Ubuntu 16.04 and kernel 4.10 hawaii is not always working well. My current kernels are - 5.021 amd opencl 18.20 or 19.20. I can't find these os with older kernels.
I am using Windows 8.1, AMD 16.9.2. The R9 390 can work now, all 6 GPU are recognized.
I benchmark it to DAG 378. It can work. But if I use 379, it will show

Is that because of the old AMD driver?
