CODE VMIN-SHIFT-0x129-0x12B
Severity: Critical
Difficulty: Advanced
Vmin Shift Ring Bus Instability
Elevated operating core voltages (Vcore/VID requests exceeding 1.55V) triggered cumulative silicon degradation (Vmin shift) within the Ring Bus and tree clock domains. Microcode revisions 0x129 and 0x12B address VID cap clamping and high-voltage idle/light-load spikes, but pre-existing degradation causes persistent ring clock sync timeouts and execution crashes.
