Latest one, i personally use 19.3.2 with compute mode switcher and atikmdag patcher.
are your cards stock or modded bios and what are your results?
Yes all cards uses modded bios since my straps still kinda better then straps in miner. So i only use rxboost on top.
btw if you change rxboost number or GPU clock its good to always pre-tune dcri at asm2,
