Vmin Shift Instability Root Cause
Intel® has localized the Vmin Shift Instability issue to a clock tree circuit within the IA core which is particularly vulnerable to reliability aging under elevated voltage and temperature. Intel has observed these conditions can lead to a duty cycle shift of the clocks and observed system instability.
Intel® has identified four (4) operating scenarios that can lead to Vmin shift in affected processors:
- Motherboard power delivery settings exceeding Intel power guidance.
a. Mitigation: Intel® Default Settings recommendations for Intel® Core™ 13th and 14th Gen desktop processors. - eTVB Microcode algorithm which was allowing Intel® Core™ 13th and 14th Gen i9 desktop processors to operate at higher performance states even at high temperatures.
a. Mitigation: microcode 0x125 (June 2024) addresses eTVB algorithm issue. - Microcode SVID algorithm requesting high voltages at a frequency and duration which can cause Vmin shift.
a. Mitigation: microcode 0x129 (August 2024) addresses high voltages requested by the processor. - Microcode and BIOS code requesting elevated core voltages which can cause Vmin shift especially during periods of idle and/or light activity.
a. Mitigation: Intel® is releasing microcode 0x12B, which encompasses 0x125 and 0x129 microcode updates, and addresses elevated voltage requests by the processor during idle and/or light activity periods.
