AMD graphics drivers have caught changing the CPU settings in the BIOS without the user’s knowledge

According to Igor’s Lab, AMD graphics drivers are capable of changing BIOS settings related to the Ryzen CPU configuration. AMD drivers have the ability to tamper with Precision Boost Overdrive (PBO) and Precision Boost settings without the user’s knowledge, which can lead to crashes.

AMD recently integrated the Ryzen master module into the graphics driver. This happened with the release of Radeon Software: Adrenalin Edition 22.3.1. This module makes changes to the CPU configuration in the BIOS. The issue only affects systems that combine AMD Ryzen processors and AMD Radeon graphics cards – if you have an Intel CPU, don’t worry.

For unknown reasons, changing the graphics card profiles in the Radeon Software settings also enables the PBO or CPU OC option in the motherboard BIOS – automatic processor overclocking. This will reset user settings with frequency and CPU power limit and enable maximum CPU automatic overclocking. In some cases, this can affect the stability of the system, although the processor has protection systems, so physical damage is unlikely.

In general, the situation can be annoying, especially for users who manually set the processor overclocking parameters or lower the CPU voltage and power consumption through the BIOS settings. As a result, at AMD Adrenalin’s whim, you’ll have to manually set the settings again. Another option is to use the third-party Radeon Software Slimmer, which allows you to remove the Ryzen Master module from Adrenalin software.
