    Setting up RX550

    The main idea is to have 4.13 kernel and OpenCL from 16.60 driver. If you can, do amdgpu-pro-uninstall.

    Download 4.13 kernel:

    
    wget https://download.hiveos.farm/kernels/linux-headers-4.13.12-mytest_1_amd64.deb
    wget https://download.hiveos.farm/kernels/linux-firmware-image-4.13.12-mytest_1_amd64.deb
    wget https://download.hiveos.farm/kernels/linux-image-4.13.12-mytest_1_amd64.deb
    

    And install it:

    
    dpkg -i linux-headers-4.13.12-mytest_1_amd64.deb
    dpkg -i linux-firmware-image-4.13.12-mytest_1_amd64.deb
    dpkg -i linux-image-4.13.12-mytest_1_amd64.deb
    

    Choose booting kernel to the latest: grub-set-default "1>0"; update-grub

    Reboot and check if you’ve booted the right kernel:

    
    uname -a
    Linux rig2 4.13.12-mytest #1 SMP Thu Nov 9 15:31:09 EET 2017 x86_64
     x86_64 x86_64 GNU/Linux
    

    Go to folder with drivers in Hive and install only OpenCL from 16.60 version:

    
    cd /hive-drivers-pack
    tar xvf amdgpu-pro-16.60-379184.tar.xz
    cd amdgpu-pro-16.60-379184
    ./amdgpu-pro-install --compute
    

    And, finally, reboot.

    For sgminer get attached kernel.tar.gz and replace kernels in /hive/sgminer_gm folder on the rig. RX 550 has only 512 shader cores so there is no sense to set 'rawintensity' over 512.

    Recommended settings are:

    “rawintensity”: 420

    “gpu-threads”: “2”

    And in case you are lazy, you can try this image. It works for RX 550 only and is based on the latest Hive OS 0.5-20 with the core 4.13.
