Here's my setup:

AMD Ryzen 5 1600 3.2GHz 16MB L3 Box processor (YD1600BBAEBOX)

Asrock AB350M Pro4 AMD B350 Socket AM4 Micro ATX motherboard (90-MXB520-A0UAYZ)

2 x G.Skill Aegis 8GB DDR4 3000MH (F4-3000C16S-8GISB)

On the BIOS https://www.asrock.com/MB/AMD/AB350M%20Pro4/index.us.asp#BIOS" rel="nofollow - download page it is stated for BIOS version 6.00 and higher:
*ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system.

On the https://www.asrock.com/MB/AMD/AB350M%20Pro4/index.us.asp#CPU" rel="nofollow - CPU Support List page for this motherboard the YD1600BBAEBOX CPU isn't listed, but YD1600BBM6IAF (Pinnacle Ridge) and YD1600BBM6IAE (Summit Ridge) are shown. It seems this means the 6.xx BIOS versions are not recommended for my YD1600BBAEBOX CPU? However the information shown seems conflicting, as the final column (Validated since BIOS) shows P6.40 and All for these two CPU's (YD1600BBM6IAF and YD1600BBM6IAE).

Please advise, which BIOS version is recommended for my setup?
