Intel Raptor Lake CPUs are crashing more frequently due to summer heatwaves, Firefox dev says

EUROPE AND OTHER NORTHERN HEMISPHERE REGIONS, JUL 14 – Intel's 13th and 14th generation CPUs suffer crashes due to voltage regulation bugs worsened by high temperatures, causing widespread instability during heatwaves, Mozilla Firefox reports show.

  • On July 2, as Europe’s heatwave peaked, Mozilla recorded surging crashes on systems using Intel’s 13th and 14th gen Raptor Lake CPUs, according to a Firefox developer at Mozilla.
  • On July 22, 2024, Intel confirmed these chips shipped with flawed microcode causing voltage regulation errors under heavy load, and timing irregularities that worsen at higher temperatures.
  • Gabriele Svelto mapped heat wave zones by tracing Firefox crash origins, noting under heavy load voltage spikes worsen with high ambient temperatures, causing system crashes.
  • Mozilla disabled its automated crash-reporting bot to prevent overload after it was logging crashes almost exclusively from Raptor Lake systems.
  • Meanwhile, users are advised to avoid Raptor Lake chips until the instability is resolved.

While Europe is going through a particularly hot summer, the problems of instability of Intel Raptor Lake processors are resurfaced. A developer of Firefox has revealed a resurgence of crash reports related to these CPUs, directly correlated with the rise of temperatures on the continent. Core i9 processors of 13th and 14th generation, already known [...] Read more Intel Raptor Lake processors unstable in the face of heat: crashes resurface in E…

It is still worth paying special attention to computers using Intel Raptor Lake processors during the summer months, as the European heat waves have once again brought to the surface a serious performance issue with Intel's 13th and 14th generation desktop Core chips, which is reflected in an increase in system crashes.

What do crash reports of a web browser have to do with the weather map? Apparently more than one would assume. An observation at Mozilla now provides new insights into a known hardware problem. read more on t3n.de
