AMD Ryzen™ Master Application
With all groups active, you change the core speed and hit Apply. You get the message
that Ryzen Master must initiate a Windows Restart. Normally changing the core speed
does not require a Restart, but Ryzen Master is also reacting to the differences between
the memory control group and the current settings, thus attempting to apply the
profile’s memory control group, too.
By deactivating the memory control group, the Apply will immediately apply the core
speed change without the Restart necessary for memory changes since Ryzen Master is
ignoring the memory control group. Whenever you’re ready to include the memory
control group in the overclocking action, re-active the group, make your changes and
Apply, proceeding with the Restart or Shutdown as advised by Ryzen Master.
It’s a good idea to verify the performance increase and stability by running CPU performance
benchmark(s) and stability tests (example: Maxon’s CINEBENCH R15). Please close all
background apps to ensure stable and consistent performance results run-to-run, but expect
some variation.
The recommendation is to increase the CPU clock in small steps while monitoring CPU
performance, stability and CPU, motherboard, system and GPU temperatures.
Once an unstable CPU clock has been reached and the CPU temperature is not too high it’s
possible to increase the CPU voltage in small steps to see if the increased CPU voltage allows
stable operation at higher frequencies.
4. The Cores Disabled controls allow the number of active cores to be reduced from the stock
processor’s total cores. This might be done to attempt to achieve higher core frequencies with
fewer cores active. The button controls are used to select which core count to disable, which
depends on how many cores the stock processor has. For example, disabling 8 cores from a
16-core processor results in 8 active cores.
Disabling cores requires a Windows Restart that Ryzen Master will automatically initiate, then
Ryzen Master will automatically re-start for you to continue.
Enabling cores requires a Windows Shutdown and manual system restart that you will be
instructed to initiate, or to cancel.
Ryzen Master requires that the Windows 10 Power Options be configured such that the Power
Button mode is set with Fast Boot disabled. This is necessary to allow the processor cores to
all be enabled after a system power cycle.
Note: Memory Overclocking Support
Note: Memory overclocking, described in items 5, 6, and 7, is a complex feature requiring
coordination of Ryzen Master, motherboard BIOS and memory control hardware on
implementation. The Memory overclocking voltages (5), speed (6) and timing parameters
(7) will be supported in a future version of Ryzen Master. Until then, these values will be
