AMD Adrenalin software allegedly changes user-defined BIOS CPU settings

Reports are emerging suggesting that AMD’s Adrenalin software for Radeon graphics cards is inadvertently changing the Precision Boost Overdrive settings of systems equipped with Ryzen CPUs. The fact that it’s doing this without the user’s consent is the problem. When applying GPU profiles, auto-activation PBO can lead to issues for users with stable overclocks.

News of the problem comes through Igor’s Laboratory after an investigation. It says the integration of AMD’s Ryzen Master CPU software and Adrenalin Radeon software is by default allowing the program to change CPU overclocking parameters without user consent.

The problem is not dangerous, but it can cause system instability, especially if a user has a manually adjusted overclock near the threshold of stability, at which point any further changes to the CPU configuration can lead to system crashes.

Modern CPUs have comprehensive protection mechanisms built in and AMD’s Precision Boost settings are generally conservative, so any damage to the CPU is highly unlikely. Changes only occur on systems with an AMD Radeon GPU and Ryzen CPU. Systems with Intel CPUs are not affected as AMD software obviously cannot access Intel CPU settings.

If you are concerned that your overclock might be affected, there are a few workarounds. The first may be obvious. Save your BIOS profile so it can be reactivated easily. The second option is to download a third-party app called Radeon Software Slimmer, which has the option to remove the Ryzen Master component of the Adrenalin software. Doing so removes any possibility of CPU manipulation.

Easy-to-use, stable, and reliable auto-overclocking tools are indeed a good thing, but only if the user is aware of the changes being made and permission is given. If AMD is more transparent in their future Adrenalin releases, there’s no reason why this kind of feature shouldn’t remain. It is the changing of settings without the user’s knowledge that is the real problem. AMD shall allow the user to disable any type of automatic OC without explicit permission.
