o If Live Monitoring is on, the Speed setting can be turned off if the user wishes to suspend
CPU speed sampling and display. When Speed sampling is suspended, no speed will be
displayed in the Profiles, but Speed will be sampled once and displayed when moving to
the Current view.
o Speed sampling typical presents much less than 1% load on the CPU in combination with
Temperature sampling.
Temperature
o If Live Monitoring is on, the Temperature setting can be turned off if the user wishes to
suspend die temperature sampling and display. When Temperature sampling is suspended,
no temperature will be displayed in the Profiles, but Temperature will be sampled once and
displayed when moving to the Current view.
o Temperature sampling typically presents less than 1% load on the CPU in combination
with Speed sampling.
3. Show Histogram
o Within the Current view, the user can choose to show a real-time, dynamic line graph of
the speed of each CPU core and the die temperature. This feature requires that Live
Monitoring be on and either or both of Speed and Temperature monitoring enabled.
o Under system idle conditions, the graphically-significant histogram feature presents less
than 3% load on the CPU, depending on core count. However, under high-thread-count
applications or heavy multi-tasking, the CPU load can become significant and degrade the
performance of the application(s) of interest. If the user wishes to maximize the
application performance under these conditions, the Show Histogram feature can be turned
off, suspending the state of the histogram display in the Current view.
4. Update Interval
o The Update Interval is the sample rate of the CPU cores’ speeds and die temperature. The
sample rate defaults to one second and can be increased in one-second increments up to
five seconds.
Note: When application performance is critical, such as when running a benchmark
application, it is typically easier to use the Windows Task Manager to set the priority
of the application to “Above Normal.” This allows the Ryzen Master Live
Monitoring to remain active but it may be suppressed during the heavier resource-
consumption phases of the application.
5. PROCHOT NOT FOR TYPICAL USE
o The PROCHOT signal within the motherboard design tells the processor that other system
elements are overheating or approaching a limit and allows the processor to throttle back
and gracefully degrade performance.
o When set by the expert user, the Ryzen Master PROCHOT control feature disables the
processor’s reaction to the motherboard’s PROCHOT signal.
o This feature is intended only for extreme overclocking cases where the expert user wishes
the processor to ignore the PROCHOT signal.
