Installing Previous AMD Drivers for Troubleshooting

Hi all,

I want to install a past version of the AMDGPU drivers (current is 18.10-572953) because I have stability issues with the majority of my rigs. I want to test if the driver is causing my OpenCL Call Hang on over 60 of my rigs!!! Rigs are 8xRX470, identical memory and specs, modded with OC and timing, then OC and UV applied by Hive. I have removed UV and decreased OC, but still have instability for the majority of my rigs.

Can anyone shed some light on the install process? Is it identical to installing AMDGPU on any other Linux server OS Installation? Thanks!
