AMD Confirms Adrenalin Bug Causes Constant SSD Writes

AMD has confirmed a software defect in its Radeon Adrenalin graphics drivers that triggers continuous, unauthorised solid-state drive write activity even whilst systems sit idle. Confirmed on 10 November 2026, the issue affects driver versions 26.10.1 and 26.10.2, stemming from the External Events Client Module background process, known as atieclxx.exe. For Malaysian PC gamers, workstation users, and system builders running Radeon hardware, the bug threatens premature flash memory wear by accumulating tens to hundreds of gigabytes in unneeded daily writes. AMD has committed to rolling out a corrective update via Adrenalin version 26.11.1 later in November 2026.

Key Facts

AMD has officially acknowledged a driver defect affecting Radeon graphics cards running Adrenalin builds 26.10.1 and 26.10.2, where an auxiliary background module continuously writes data to storage drives. A permanent software patch, version 26.11.1, is scheduled for release later in November 2026 to resolve the unprompted storage activity.

AMD Adrenalin driver versions 26.10.1 and 26.10.2 can continuously write data to solid-state drives at rates exceeding 1.5MB/s even when the computer remains idle.

Which AMD Drivers Cause the SSD Write Defect?

The continuous solid-state drive write defect specifically impacts AMD Adrenalin Radeon driver versions 26.10.1 and 26.10.2 through the External Events Client Module. Identified as atieclxx.exe within the AMD External Events Utility, the background process continuously commits unprompted data to the host drive at rates varying between 0.3MB/s and 1.5MB/s.

Although these write rates appear modest in isolation, persistent background execution creates substantial cumulative wear on storage hardware over extended periods. At sustained write speeds of 5MB/s, unchecked system operations account for approximately 432GB of data writes in twenty-four hours, reaching an estimated monthly total of 13TB under uninterrupted operation.

"HUGE AMD ADRENALIN BUG (26.10.1 & 26.10.2)! atieclxx.exe is constantly writing data to SSDs, even when idle. Adrenaline driver: 19.5 GB of I/O writes in just 12 hours!"Tomasz Gawroński (@GawroskiT)

Continuous background writes from atieclxx.exe can generate up to 432GB of drive writes in a single day under uninterrupted 5MB/s write conditions.

How Can Users Identify and Mitigate the Bug?

Radeon users can verify whether their systems are actively affected by inspecting the Windows Resource Monitor to observe disk activity for atieclxx.exe. AMD confirms that not all Radeon systems exhibit the issue, and users can attempt temporary workarounds including halting the background service or disabling Resizable BAR.

Affected community members have documented two primary interim measures, though both entail distinct operational compromises:

• Disabling the AMD External Events Utility via Windows Services stops rogue writes, but reportedly impairs Adrenalin hotkeys and certain display features.
• Disabling Resizable BAR in the system BIOS halts write activity on certain setups, but directly degrades graphics performance during gaming workloads.

Neither disabling the AMD External Events Utility nor toggling Resizable BAR in the BIOS provides a guaranteed resolution without sacrificing system functionality or gaming performance.

What It Means for Malaysian Buyers

Malaysian PC owners running AMD Radeon graphics cards should avoid updating to Adrenalin 26.10.1 or 26.10.2 until AMD releases the 26.11.1 patch. While no regional pricing or hardware distribution changes apply to this driver glitch, local users should monitor storage health to avoid unneeded write wear on local warranty-backed drives.

The defect is confined entirely to the software layer and does not indicate defective silicon across Radeon graphics cards sold by local authorized retailers in Malaysia. Hardware pricing, local distributor warranties, and MCMC or SIRIM certifications remain unaffected. Users running earlier stable Adrenalin releases should remain on those drivers until AMD publishes version 26.11.1 later in November 2026.

Malaysian Radeon owners should remain on older, stable Adrenalin releases until the verified 26.11.1 hotfix arrives to prevent premature solid-state drive wear.

Common Questions

Frequently asked questions address the scope of the AMD Radeon Adrenalin storage write bug, verified remediation schedules, and the efficacy of temporary user workarounds. System diagnostics confirm that drive writes can be inspected directly via Windows tools while users await official software updates from AMD.

Official driver patches remain the only confirmed permanent solution to prevent background solid-state drive degradation without losing graphics features.

When will AMD release a permanent fix for the driver bug?

AMD has confirmed that the upcoming Adrenalin 26.11.1 driver update will resolve the continuous write defect. The update is scheduled to roll out later in November 2026, though the company has not yet provided an exact calendar launch date for the patch.

Does the SSD write defect affect every AMD Radeon system?

No, AMD has confirmed that not every Radeon user running driver versions 26.10.1 or 26.10.2 is impacted. Users can verify their vulnerability by opening the Windows Resource Monitor and checking whether the atieclxx.exe process is actively writing data while the computer sits idle.

Do the current temporary workarounds compromise PC performance?

Both temporary workarounds carry distinct operational drawbacks for active systems. Disabling the AMD External Events Utility disrupts Adrenalin hotkey shortcuts and display functions, while disabling Resizable BAR in the motherboard BIOS lowers gaming frame rates. Furthermore, neither workaround succeeds across every reported hardware configuration.
