AMD Adrenalin 26.11.1 Driver Fixes Excessive SSD Writes

AMD has released the optional Adrenalin 26.11.1 graphics driver on 13 November 2026 to resolve a bug causing continuous background writes to system SSDs on Radeon-powered PCs. Affecting Radeon RX 7000 series graphics products and newer, the issue stemmed from the AMD External Events Client Module process, atieclxx.exe, which wrote between 0.3MB/s and 5MB/s even when systems sat idle. For Malaysian PC users running affected Radeon hardware, installing this official update removes up to approximately 432GB of unnecessary daily drive writes without disabling Radeon features or reducing gaming performance.

Key Facts

The AMD Adrenalin 26.11.1 driver is an optional software release issued on 13 November 2026 to stop excessive SSD writes triggered by the atieclxx.exe background process. AMD's Adrenalin 26.11.1 update targets Radeon RX 7000 series graphics products and newer experiencing up to 432GB of daily background writes.

What Causes the Excessive SSD Writes on Radeon PCs?

The excessive system drive writes are caused by the AMD External Events Utility, specifically its External Events Client Module background process known as atieclxx.exe. Users observed this process continuously writing data to SSDs at rates ranging from 0.3MB/s to 5MB/s, even while PCs remained idle.

At the upper reported rate of 5MB/s, uninterrupted background activity could generate approximately 432GB of writes to a system SSD within a single day, accumulating hundreds of gigabytes over time. Before issuing the patch, AMD advised users to inspect drive activity using Windows Resource Monitor to verify whether the process was affecting their system. Continuous atieclxx.exe activity at 5MB/s can write approximately 432GB of unnecessary data to a system SSD in a single day.

Which Radeon GPUs and Scenarios Are Fixed by Adrenalin 26.11.1?

According to AMD's release notes, the Adrenalin 26.11.1 optional driver resolves excessive system drive writes on Radeon RX 7000 series graphics products and newer. The update specifically addresses two distinct triggers: idle background writes and unnecessary disk activity during desktop window management.

• Idle system writes: Stops continuous background writes to the system drive when a Radeon RX 7000 series or newer PC sits idle.
• Window manipulation: Fixes similar excessive write behaviour occurring when users move or resize application windows.

While the release notes classify Adrenalin 26.11.1 as an optional update rather than a mandatory release, affected Radeon users are advised to install it directly. Adrenalin 26.11.1 eliminates both idle background writes and window-resizing SSD writes on Radeon RX 7000 series and newer hardware.

What Workarounds Existed Before the Official Driver Update?

Before Adrenalin 26.11.1 arrived, affected Radeon users relied on three temporary workarounds: disabling the AMD External Events Utility, turning off Resizable BAR in the system BIOS, or running an unofficial open-source patch. Each official workaround carried functional drawbacks, making the new driver update the recommended fix.

• Disabling the AMD External Events Utility stopped the writes, though doing so could interfere with certain Radeon features and hotkeys.
• Switching off Resizable BAR in the BIOS offered another option, yet it could potentially reduce gaming performance.
• An unofficial open-source tool named Radeon-atieclxx-SSD-Fix blocked the problematic writes without disabling the External Events Utility.

Now that AMD has published an official patch, users do not need third-party tools or BIOS compromises to protect their system drives. Installing Adrenalin 26.11.1 removes the need to disable the AMD External Events Utility or Resizable BAR to halt SSD writes.

What It Means for Malaysian Buyers

For Malaysian PC owners and prospective buyers, Adrenalin 26.11.1 is available immediately as a direct download via AMD's official website following its 13 November 2026 release. The source report confirms no separate Malaysian regional rollout schedule, local pricing, or distributor-specific advisories, as software driver updates distribute globally.

Malaysian gamers using Radeon RX 7000 series graphics cards or newer who previously disabled Resizable BAR or used Radeon-atieclxx-SSD-Fix should transition to Adrenalin 26.11.1. No local hardware pricing, Malaysian retail bundles, or local warranty guidance is provided in the source material. Malaysian users with Radeon RX 7000 series or newer GPUs can download Adrenalin 26.11.1 directly from AMD without waiting for regional distribution.

Common Questions

How do I check if my PC has the atieclxx.exe SSD write bug?

Before updating, AMD recommended opening Windows Resource Monitor to check whether the External Events Client Module process (atieclxx.exe) is writing continuously to your system SSD. Affected Radeon PCs recorded continuous background write rates between 0.3MB/s and 5MB/s even while sitting idle.

Should I keep using Radeon-atieclxx-SSD-Fix or disable Resizable BAR?

No, AMD advises affected users to install the official Adrenalin 26.11.1 driver rather than relying on temporary workarounds. Disabling Resizable BAR in BIOS can reduce gaming performance, while disabling the AMD External Events Utility can disrupt Radeon features and hotkeys.

Which Radeon graphics cards are covered by the Adrenalin 26.11.1 fix?

According to AMD's release notes, the Adrenalin 26.11.1 fix applies to Radeon RX 7000 series graphics products and newer models. It resolves excessive SSD writes both when the computer is idle and when moving or resizing application windows on the desktop.
