If you have an ASRock X470 Master SLI/AC you may get improved memory compatibility with the P3.20 version BIOS/UEFI update including AGESA 0.0.7.2.
Running CMK16GX4M2A2400C16 (2 kits) 16-16-16-39-55-1T, 2400MHz @1.2v
Old P1.9 BIOS/UEFI with AGESA 1.0.0.6
I was not able to use the original timings when overclocked and occasionally memory retraining would kick-in again on boot every now and then.
20-20-20-48-68-1T, 2933MHz @1.35v, SOC@0.920v (oc stable, 4 sticks)
New P3.20 BIOS/UEFI with AGESA 0.0.7.2
I was able to use the original timings while overclocked and the memory retraining problem is now gone.

Did anyone else notice any memory improvements with their Ryzen boards with AGESA 0.0.7.2 updates?
