Well, i would suggest to use 19.20 then :)

I just did a quick test on 20.20 , kernel 5.8.0, Vega 56, stock clocks, REF changed to 9k 20.10 -> 36.62 Mh 20.20 -> 35.97 Mh

Changed REF to 22k 20.20 -> 36.71 Mh

Works fine..

@Eliovp I see applying timings for incorrect memory state:

$ sudo amdmemorytweak/amdmemtweak --i 5 --c
GPU 5:  Vega 10 XT [Radeon RX Vega 64]  pci:0000:0b:00.0
Memory state: 800MHz
Memory: Hynix HBM2

Current working memory 949Mhz.
