Hello Gaijin Team and Community.
Recently, I have been encountering a critical issue with BattlEye (BEDaisy.sys) causing a BSOD, and these crashes have become much more frequent lately.
I investigated the cause. It turns out that BIOS versions, GPU/Realtek drivers, and RAM stability actually played no part here. Furthermore, I confirm that a software-level conflict with Spotify was also completely unrelated to the issue.
The actual root cause is indeed hardware-level “Phantom” CPU instability. It was highly selective: for example, PUBG, which used the exact same BattlEye anticheat, ran perfectly without any crashes.
Personally, I had never experienced any system issues with such “unstable” CPU overclock before. However, those cases on WT forums blaming “CPU instability” were describing the exact same problem I had.
Adding just 0.01v to the core voltage (from 1.32v to 1.33v) completely solved the problem, stopped the BSODs, and apparently stabilized BEDaisy.sys. It seems that opening the previously falsely blamed Spotify (or a web browser) caused a minor voltage drop under peak load, which instantly triggered the BattlEye restriction.
