AMD confirms Radeon bug causing excessive SSD writes

AMD Radeon driver bug causes excessive SSD writes

AMD has confirmed that its AMD Software 26.10.1 and 26.10.2 drivers contain a bug that causes excessive SSD writing. While the SSD writes are small, 0.3-1.5 MB/s on most user reports, it means that AMD Radeon GPU users are having their SSDs unnecessarily worn. Gigabytes of writes can take place over hours, and over months these writes could reach the multi-terabyte range.

According to a post from an AMD representative on Reddit, the company plans to introduce a fix with its November drivers (likely AMD Software 26.11.1). The problem seems to come from AMD’s External Events Client Module (atieclxx.exe). It appears to have entered some kind of “infinite loop”, making the software continuously write data. While the writes are small and shouldn’t impact overall system performance, it has left AMD Radeon users concerned.

These SSD writes can add up fast

One user reported over 20GB of SSD writes in a matter of hours and calculated that, over 30 days, the bug could cause 1.7 TB of writes. While it is unclear how much of an impact this could have on an SSD’s lifespan, unnecessary writes aren’t a good thing.

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!
(as of writing this tweet it passed 20 GB 🙃)
Current rate: 0.65 MB/s = 56 GB/day if sustained.

So far, AMD users on Reddit have uncovered two potential workarounds for this bug. The first is to disable AMD External Events Utility through Windows Services and disable Resizable BAR in their motherboard’s BIOS. Details for both methods are available on Reddit; however, neither method is ideal. Disabling the AMD External Events Utility can affect the functionality of some GPU features. Disabling Resizable BAR can also reduce your GPU’s performance.

For most users, this write bug is small enough to ignore until AMD releases new GPU drivers. After all, a fix should be available this month. That said, AMD needs to address this bug quickly, as nobody wants their SSDs to be prematurely worn, not with today’s hardware prices…
