Overview
- AMD acknowledged the problem to users on its community forum and said it was investigating after renewed Reddit reports, with company representatives indicating a fix is expected in a future Adrenalin driver.
- The behavior is tied to the AMD External Events Utility (atieclxx.exe), which users report can generate sustained writes measured between about 0.3 MB/s and 5 MB/s when systems are idle.
- Reports span multiple Adrenalin releases, different Radeon GPUs, and both Windows 10 and Windows 11, though not every Radeon system appears affected.
- Users have found temporary workarounds such as stopping the AMD External Events service or disabling Resizable BAR, but both actions can remove Radeon features or reduce gaming performance.
- No public patch has been released yet and Adrenalin Edition 26.10.2 did not list this issue in its notes; users can monitor disk activity with Windows Resource Monitor to check for excessive writes while awaiting AMD’s official driver update.
