For Ryzen enable eco mode or manually tweak PBO to hard limit max power consumption.
Disable Auto OC and similar features in bios to allow SoC / IMC downclock.
Enable aggressive core parking.
You lose some burst responsiveness but gain a lot of near-idle power saving.
On my asrock it's :
OC Tweaker
SB Core Spread Spectrum : Disabled
SoC Uncore OC Mode : Disabled
Advanced
AMD Overclocking - PBO : Advanced
AMD CBS - NBIO - SMU - EfficiencyModeEN : Enabled
