AMD has released the optional Adrenalin 26.11.1 driver, fixing an issue where Radeon RX 7000 series and newer GPUs continuously write large amounts of data to the system drive. This excessive writing can occur when the computer is idle or when moving or resizing application windows.
AMD previously confirmed that the issue is related to the External Events Client Module process atieclxx.exe in drivers 26.10.1 and 26.10.2. Users reported write speeds of approximately 0.3MB/s to 5MB/s, which translates to daily write volumes of around 26GB to 432GB.
Before the driver fix was released, some affected users temporarily mitigated the issue by disabling the External Events Utility, turning off Resizable BAR, or using community-developed open-source interception tools.
Currently, the Adrenalin 26.11.1 optional driver provides this fix. The full release notes and the specific scope of the fix are yet to be further verified.
