Does not work with 17.8-BETA drivers. I will not change drivers for new ones.
Problem is that your drivers turn 3 years old now. AMD had a lot of breaking changes with their drivers, so if I want my code to run on older ones I need to install them and do all the build stuff for them as well. Its already plenty of work to go back to 18.10 drivers (RX 580) or 18.50 (Vegas), which are the oldest I currently build for.
Why do you want to stick on that old drivers? The newer ones are really not bad - and what was introduced with the old blockchain drivers is now part of the newer ones. Afaik there is no technical reason to stick on the (very) old ones.
We all know the 17.8 Beta Crimson Blockchain Driver was the best driver. I just wish AMD will update the Blockchain Driver to a 2020 edition since more are interested now in GPU mining. It is just more better for mining rigs.
I don't believe Adrenaline Drivers completely have what the Blockchain driver had, what was introduced to it. Cos I have some rigs with the same particular brand of RX 580 GPUs that run perfectly with the Blockchain Driver with good hashrates, but go crazy and/or low hashrate when I install the 2019 or 2020 edition Adrenaline drivers with compute mode settings.
However, on the rest of my other rigs with well-known brands of GPU, Adrenaline 2020 edition is perfect.
