If I am understanding correctly people are seeing best results with the following for RX570/580

RXboost -1 and strap -1
Increase Core to around 1180,  memory at around 2050-2100
DDU and install latest AMD drivers

The last one is what I want to confirm as I am using 18.3.1? for some time and haven't had issues, so wanted to confirm before I DDU and reinstall on all rigs. Also I saw some mentions of 20GB virtual, I usually run 16 Minimum, did I miss something in release notes about upping this?

Thanks!
