AMD Ryzen Processor Overclocking User’s Guide

AMD Ryzen Master Application

The number of enabled cores can be verified by opening the Windows 10 Task Manager and the

Performance tab (change the CPU graph to display Logical processors:

Figure 9: Windows 10 Task Manager with six enabled CPU cores

Note that since the disabled cores have been hidden from the OS, they will not appear as idle or

parked in any Windows resource-monitoring application until enabled.

Note also that most applications that report the number of cores or threads, such as benchmarks,

sample the CPU resources only when first started and will not register changes to CPU core count

or frequency that you change via AMD Ryzen Master. Always re-open such monitoring

applications after AMD Ryzen Master changes are applied.
