AMD Confirms Its GPU Drivers Are Overclocking CPUs Without Asking
AMD has confirmed to Tom's Hardware that a bug in its GPU driver is, in fact, changing Ryzen CPU settings in the BIOS without permission. This condition has been shown to auto-overclock Ryzen CPUs without the user's knowledge. From the report: Reports of this issue began cropping up on various social media outlets recently, with users reporting that their CPUs had mysteriously been overclocked without their consent. The issue was subsequently investigated and tracked back to AMD's GPU drivers. AMD originally added support for automatic CPU overclocking through its GPU drivers last year, with the idea that adding in a Ryzen Master module into the Radeon Adrenalin GPU drivers would simplify the overclocking experience. Users with a Ryzen CPU and Radeon GPU could use one interface to overclock both. Previously, it required both the GPU driver and AMD's Ryzen Master software. Overclocking a Ryzen CPU requires the software to manipulate the BIOS settings, just as we see with other software overclocking utilities. For AMD, this can mean simply engaging the auto-overclocking Precision Boost Overdrive (PBO) feature. This feature does all the dirty work, like adjusting voltages and frequency on the fly, to give you a one-click automatic overclock. However, applying a GPU profile in the AMD driver can now inexplicably alter the BIOS settings to enable automatic overclocking. This is problematic because of the potential ill effects of overclocking -- in fact, overclocking a Ryzen CPU automatically voids the warranty. AMD's software typically requires you to click a warning to acknowledge that you understand the risks associated with overclocking, and that it voids your warranty, before it allows you to overclock the system. Unfortunately, that isn't happening here. Until AMD issues a fix, "users have taken to using the Radeon Software Slimmer to delete the Ryzen Master SDK from the GPU driver, thus preventing any untoward changes to the BIOS settings," adds Tom's Hardware.
