Intel has localized the Vmin Shift Instability issue to a clock tree circuit within the IA core, which is vulnerable to reliability aging under high voltage and temperature.
The observed conditions can lead to a duty cycle shift of the clocks, resulting in system instability that users may experience during high performance activities.
To address Vmin shift, Intel identified four main operating scenarios that can trigger issues, recommending default settings and not exceeding specified power guidance.
Microcode updates are essential for managing performance states and voltage requests; Intel has planned several updates for the 13th and 14th Gen processors to mitigate these risks.
