It ranks mainly on source trust: TechPowerUp is the most reliable outlet we track on this subject, and is the only one on the story so far.

AMD identified a bug in Radeon driver versions 26.10.1 and 26.10.2 that triggers excessive SSD writes. The External Events Client Module, running as atieclxx.exe, enters an infinite loop and generates write activity ranging from 0.3 MB/s to 1.5 MB/s, with some users reporting sustained rates of 5 MB/s. Over extended periods, this accumulation can cause unnecessary wear to system drives.
The problematic module is part of AMD's External Events Utility, which normally handles monitor detection and Radeon software hotkey responses. The constant random writes pose a particular concern because SSD lifespan depends on endurance against such activity, and the unnecessary wear affects expensive NAND Flash storage.
AMD will release Adrenalin driver version 26.11.1 to resolve the issue. Users currently running the affected driver versions should expect this update to stop the excessive write activity.
What happened
AMD has confirmed that the current versions of Radeon drivers, Adrenalin 26.10.1 and Adrenalin 26.10.2, are experiencing an issue that causes excessive SSD writing. This problem results in the SSD writing dozens of gigabytes of data unnecessarily. The culprit appears to be AMD's External Events Client Module, which runs under the name atieclxx.exe on Windows systems. This module is causing some users' system drives to be constantly busy with writes. Reports indicate that the write rate ranges from 0.3 MB/s to 1.5 MB/s, with one Reddit user reporting sustained activity at 5 MB/s. The process is part of AMD's External Events Utility, which manages tasks such as detecting monitors and responding to Radeon software hotkeys.
