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.
