Radeon Adrenalin: Graphics driver overclocks AMD Ryzen without being prompted through BIOS

The AMD Radeon Adrenalin graphics driver changes various BIOS settings without prompting and thus overclocks Ryzen processors after the OC profiles for the graphics card have been loaded. The driver overwrites previously user-defined settings in the UEFI without warning.

AMD Radeon Adrenalin changes values ​​in the Curve Optimizer

The driver overclocks Ryzen CPUs of the Vermeer type based on the Zen 3 architecture without being prompted and at the BIOS level. To do this, the values ​​previously stored in the UEFI for the Curve Optimizer are modified in such a way that the processor is pushed to the limit in steps of 50 MHz. A behavior that the community member “la-calli” he had already observed it on March 24 and documented it in a reader’s article.

  • [Leserartikel] AMD Radeon Adrenalin meddling in the BIOS

After the publishers couldn’t figure out the problem with their own systems even after several attempts, the manufacturer now has the problem on the website. tom hardware confirmed and announced new studies on the subject.

We are aware of an issue in the AMD software package that is adjusting certain AMD processor settings for some users. We are investigating the issue and will share more information as soon as we can.


also the site desktop modifier I had already made the corresponding observations with Radeon Adrenalin 22.3.1 (test) and reported on them. As the author discovered, the graphics driver is said to have overwritten the values ​​for Curve Optimizer previously stored in UEFI after loading a GPU profile.

The unstable system, which behaved very erratically and vulnerable after loading the UV profile for the used AMD Radeon RX 6800 XT (test), made us suspicious.

To rule out the previously loaded graphics card UV profile as a source of error, this was reversed and the standard GPU profile loaded. But the errors remained and a look at the BIOS finally showed why.

But now I go into UEFI and see that my settings have been completely overwritten. The curve disappeared and the processor was pushed to its absolute limit, in other words an unstable limit, apparently in steps of 50 MHz.

After reloading the UV profile for the graphics card, one of the previously saved presets was loaded into the BIOS and the errors disappeared. The website was able to reproduce the error multiple times and with different firmware versions from AMD AGESA Combo-AM4v2 to

Radeon Adrenalin release notes confirm the issue

Meanwhile, the official release notes for the latest AMD Radeon Adrenalin 22.4.1 also confirm the issue.

Ryzen CPU overclocking settings can be changed after resetting or importing a profile from Radeon Performance Tuning Options.


The problem then manifests itself in blue screens because the Curve Optimizer curve is set too aggressively, or an error message in the graphics controller GUI stating that auto overclocking failed.

What does the community say about this topic? If you have an updated graphics card and an AMD Zen 3 CPU, can you reproduce the error? The editors will be happy to receive your comments and expand the article accordingly if there are new findings.
