ROG STRIX B450-F GAMING II BIOS Manual
Precision Boost Overdrive
The items in this sub-menu allow you to set the Precision Boost Overdrive settings.
PBO Fmax Enhancer
If this item is set to [Enabled], it potentially improves the peak frequencies (‘Fmax’)
during single threaded workloads. Incompatible with the so-called ‘EDC tweak’.
Configuration options: [Auto] [Disabled] [Enabled]

Configuration options: [Auto] [Disabled] [Enabled]
Precision Boost Overdrive
This item allows you to manually set, disable, or enable the precision boost overdrive.
If this item is set to [Enabled], it allows the processor to run beyond defined values for
PPT, VDD_CPU EDC, VDD_CPU TDC, VDD_SOC EDC, VDD_SOC TDC to the limits
of the board, and allows it to boost at higher voltages for longer durations than default
operation.
Configuration options: [Auto] [Disabled] [Enabled] [Manual]
The following items appear only when Precision Boost Overdrive is set to [Manual].
PPT Limit
This item allows you to input the PPT Limit [W], Board Socket Power capability, which
is adjustable up to the motherboard programmed PPT limit.
Configuration options: [0] - [65535]
TDC Limit
This item allows you to input the TDC Limit [A], Board thermally constrained current
delivery capability, which is adjustable up to the motherboard programmed TDC limit.
Configuration options: [0] - [65535]
EDC Limit
This item allows you to input the EDC Limit [A], Board electrically constrained current
delivery capability, which is adjustable up to the motherboard programmed EDC limit.
Configuration options: [0] - [65535]
Precision Boost Overdrive Scalar
This item allows you to manually set, or disable the part runs with a scalar of
customized value.
Configuration options: [Auto] [Disabled] [Manual]
The following items appear only when Precision Boost Overdrive Scalar is set to
[Manual].
Customized Precision Boost Overdrive Scalar
The Precision Boost Overdrive Scalar increases the maximum boost voltage used
(runs above parts specified maximum) and the amount of time spent at that voltage.
The larger the value entered the larger the boost voltage used and the longer that
voltage will be maintained.
Configuration options: [2X] - [10X]
