AMD Ryzen Master Application
5.1.4 Disabling Cores
The AMD Ryzen Master application allows the user to disable a select number of CPU cores.
This may improve overclocking headroom for the remaining CPU cores or can be used to reduce
the overall CPU power consumption. Please refer to Chapter 7 for further information on AMD
Ryzen processor core configuration.
By default, the CPU runs with all cores enabled. AMD Ryzen Master supports disabling cores in
pairs. For example, an 8-core AMD Ryzen processor model can be configured to disable two,
four or six cores. Disabling all cores is not supported since the product would cease to function
with no enabled cores.
The below example outlines the necessary steps for disabling two CPU cores which results in six
enabled cores.
Figure 6: CPU Core Configuration – disabling two cores
The first step includes activating the user-editable Profile 1 by clicking “1” from the lower left
corner. In this example two cores are disabled and the settings are applied by hitting “Apply”
from the upper right corner.
