MANUAL OVERCLOCKING WITH A 3000-SERIES CPU
35AMD Ryzen Master 2.6 Reference Guide | November 2020
• Manual overclocking allows the user to experiment with higher clock speeds outside of the processor’s
automatic management.
• Frequency can be set at the core, CCX, CCD or all-cores level.
• New: With the AMD 3000-Series CPUs, the user can return to the PBO or Default modes under
automation control without a system restart.
• Note that the Precision Boost Overdrive parameters
are not applicable when using Manual overclocking.
• The system will consume the power required at the
manual settings up to the point of instability.
• CPU voltage MUST be considered
and typically set when manually
overclocking the cores.
• The displayed setting is sampled
from the state of automatic control
when Manual mode is selected.
The sampled value may or may not
be appropriate for a manual setting.
• CPU frequency can be set by dragging the bar left and right, by using
mouse or keyboard up/down or scroll wheel controls, or by entering a
specific value in the frequency field.
• Frequency values are limited to increments that the processor will set to
on Apply
• These symbols control which
cores react to a frequency
setting on any one core.
• The frequency set for one
core can apply
‒ to only that core
‒ to only that CCX
‒ to only that CCD
‒ to all cores
• This feature simplifies setting
core frequencies at different
levels of core grouping.
