AMD is investigating an issue in its GPU software suite that causes an auto-adjustment of AMD Ryzen CPU performance settings for users without permission.
The chipmaker confirmed the GPU driver bug to Tom's Hardware via a generic statement that didn't give many details, mitigation advice, or estimated fix dates.
The issue appears to affect only users who combined AMD CPUs and GPUs on the same system but doesn't affect all of those who are eligible.
AMD released Adrenalin Edition 22.4.1 yesterday, but there is no mention of the auto-overclock bug in the release notes, so it's unclear if that version addresses the problem.
The Radeon Adrenalin driver introduced the auto-overclock feature in September 2021 to offer users an easy way to increase system performance with one click, without having to fiddle with FSB speed and voltage settings manually.
If you are using the Adrenalin driver, you should upgrade to the latest available version released yesterday in the hope that AMD quietly addressed the problem via an urgent patch.
