Does anyone know why I am getting ~22mh/s on all my r9 390's 8GB with lolminer? It should be around 29mh/s

Yes, half of my 390 hawaii cards are not loading the DAG file, although they are 8Gb. The other half is hashing with only 22 Mh/s. Strangely, my tahiti cards are hashing as normal with 26-28 Mh. Of course, under linux, more precisely smos.

what tahiti cards exactly ? & are you using an old smos build or the latest ?

I'm talking about R9 280x (Tahiti) cards. They are typically with 3Gb VRAM but in 2016 I found special model XFX R9 280x with 6 Gb. They all work fine with lolminer now. I started using the latest smos in August 2020. But I had to enter the parameters
export GPU_FORCE_64BIT_PTR=1;
export GPU_MAX_HEAP_SIZE=100;
export GPU_USE_SYNC_OBJECTS=1;
export GPU_MAX_ALLOC_PERCENT=100;
export GPU_SINGLE_ALLOC_PERCENT=100;
in one of the linux system files. I can't remember which was the file. But similar solution can be found in the forums of hiveos. I think it is
in /hive/bin/miner file, just under the RIG variables. Claymore didn't work without these parameters but some other miners may work. In my case even after I entered these parameters, the display in smos looked broken with endless loops of lines. But the rig was actually working and I have full control with the web interface of the rig.
