Vmin Shift Instability Root Trigger
Intel® has situated the Vmin Shift Instability challenge in a clock tree circuit within the IA core that’s significantly susceptible to reliability getting older beneath excessive voltage and temperature situations. Intel has famous that these situations can result in a change within the responsibility cycle of the clocks and noticed system instability.
Intel® has recognized 4 (four) working situations that may trigger Vmin to alter in affected processors:
1) Motherboard energy settings exceed Intel's energy pointers.
o. Mitigation: Intel® Suggestions for Default Settings for 13th and 14th Technology Intel® Core™ Desktop Processors.
2) The eTVB Microcode algorithm that allowed 13th and 14th technology Intel® Core™ i9 desktop processors to function at superior efficiency even at excessive temperatures.
o. Mitigation: microcode 0x125 (June 2024) addresses the eTVB algorithm challenge.
three) Microcode SVID algorithm that requests excessive voltages at a frequency and period that may trigger Vmin to alter.
o. Mitigation: microcode 0x129 (August 2024) addresses the excessive voltages required by the processor.
four) Microcode and BIOS code that require excessive base voltages, which may trigger Vmin to alter, particularly during times of inactivity and/or mild exercise.
o. Mitigation: Intel® releases microcode 0x12B, which incorporates microcode updates 0x125 and 0x129 and addresses excessive CPU voltage calls for during times of inactivity and/or mild exercise.
