The root of the problem, as Intel explains, lies in a clock tree circuit within the IA core itself that becomes prone to failure when subjected to.
The big picture: Intel has finally identified all the underlying culprits behind the instability issues plaguing its 13th- and 14th-gen processors. While the company previously recognized the root cause, it did not provide a comprehensive analysis. Now, alongside the results of its lengthy investigation, Intel is also rolling out a second microcode update to hopefully put these issues to bed once and for all.
The root of the problem, as Intel explains, lies in a clock tree circuit within the IA core itself that becomes prone to failure when subjected to high voltage and temperature conditions. This failure causes a shift in the clock duty cycle, which then manifests as system instability.
Intel zeroed in on four key operating scenarios that were triggering this.
