10.4 APU Graphics Overclocking Control
Figure 14. APU Graphics Overclocking Control
With reference to Figure 14, each of the Ryzen Master 1.2 profiles offer APU graphics
overclocking control as follows. Note that the APU graphics processing functions include 2D and
3D graphics and multi-media co-processors, such as video encoding and decoding, all of which
respond to performance optimization offered by overclocking:
1. The APU GFX Clock slider controls the graphics clock with low and high limits.
a. The low limit is set by the lowest frequency supported by the GPU.
b. The high limit is fixed at 2500 MHz. This value is well above the typical limit of
GFX clock performance under normal ambient conditions.
c. The default value is sampled at the time Ryzen Master is first installed on the
system and run for the first time. The Reset Profile function uses the default value
to reset the profile tab of focus.
2. The APU GFX Voltage controls the power supply voltage for the GPU within the SOC
Power Domain
