The values can be adjusted by selecting one of the four user editable profiles (1 to 4). In the below<br />
example Profile 1 has been selected.<br />
To <strong>Over</strong>clock the CPU the user needs to adjust the CPU clock. There are five ways to do this with<br />
<strong>AMD</strong> <strong>Ryzen</strong> <strong>Master</strong>:<br />
1) dragging the yellow dot in the clock slider<br />
2) by typing in the desired CPU clock in the text box.<br />
3) by clicking the up <strong>and</strong> down buttons with mouse<br />
4) by clicking the Speed text box (left mouse button) <strong>and</strong> then dialing in the desired value using<br />
keyboard up/down button<br />
5) by activating the text box <strong>and</strong> adjusting the value with mouse scroll wheel<br />
The CPU clock can be adjusted in 25MHz steps.<br />
CPU Voltage can be adjusted by typing in a new value in the CPU VID text box. The example<br />
below uses a value of 1.40V. The CPU voltage can be adjusted in 0.00625V steps.<br />
Note: Some motherboards may apply a voltage offset from the BIOS. In this case the actual CPU<br />
voltage may be higher (or lower) than what the CPU VID value suggests. It’s always a good idea<br />
to monitor the actual voltage level (from the BIOS or with the motherboard vendors monitoring<br />
application).<br />
Caution: Raising the CPU Voltage above the stock setting is the single-most contributing factor<br />
to reduced life of the processor <strong>and</strong>/or damage due to transistor over-stress <strong>and</strong> temperature. Each<br />
individual CPU unit may respond to changes in CPU Voltage differently.<br />
The settings are not applied until the user clicks the “Apply” button in the upper right corner of the<br />
UI. Clicking “Apply” will also automatically save the settings to the active profile.<br />
Note: Under over<strong>clocking</strong> mode all CPU Cores will operate at the same frequency <strong>and</strong> voltage.<br />
It’s a good idea to verify the performance increase <strong>and</strong> stability by running CPU performance<br />
benchmark(s) <strong>and</strong> stability tests (example: Maxon’s CINEBENCH R15). Please close all<br />
background apps to ensure stable <strong>and</strong> consistent performance results run-to-run, but expect some<br />
variation.<br />
