PRECISION BOOST OVERDRIVE (PBO)
32AMD Ryzen Master 2.6 Reference Guide | November 2020
• Precision Boost Overdrive allows the processor to automatically use the power design
margin reported by the motherboard above warrantied CPU limits, potentially increasing
maximum and average core speed.
• This feature works best with a premium overclocking motherboard, a premium cooler,
and a cool ambient environment.
• With the AMD 3000-Series CPUs, the user can return to Default without a system restart
if Persistent PCD Values is set of OFF. In ON, then a restart will be requested
• These manual PBO values default to the maximum the motherboard BIOS
allows for one-button Apply to activate.
• The values can be reduced if desired before using the Apply, for example: to
increase only those parameters that are constraining the workload of interest.
