AMD Acknowledges Radeon Bug Causing Up to 5 MB/s SSD Writes, Prepares Fix

3 articles · Updated · Wccftech · Nov 8

AMD said it is investigating a Radeon driver bug that can keep writing to SSDs in the background, with a fix reportedly already committed but not included in Adrenalin 26.10.2.
User reports tie the issue to atieclxx.exe—the AMD External Events Utility—with sustained write rates ranging from 0.3 to 1.5 MB/s and one case near 5 MB/s while systems were idle.
At 5 MB/s, the process could theoretically generate about 432 GB of host writes a day, though the report says that does not directly show NAND wear and the SSD-endurance impact remains unclear.
Windows 10 and 11 users across multiple Radeon GPUs have reported the behavior, but not every system appears affected; Resource Monitor can be used to check for persistent disk writes from atieclxx.exe.
Some users say stopping AMD External Events Utility or disabling Resizable BAR reduces the writes, but both workarounds can break Radeon features or hurt gaming performance, leaving a future driver update as the cleaner fix.
