US EditionIntel issues new microcode to fix rare Vmin Shift crashes on 13th- and 14th-gen CPUs
- Intel released microcode update 0x12F in September 2024 to fix rare Vmin Shift crashes on 13th- and 14th-generation desktop processors, excluding Core Ultra 200S series.
- This update follows the major 0x12B fix that addressed voltage management bugs causing instability and accelerated CPU wear in Raptor Lake chips during light workloads.
- Vmin Shift instability caused clock duty cycle shifts and hardware damage after prolonged low-activity tasks, prompting BIOS updates incorporating 0x12F from multiple motherboard vendors.
- Intel confirmed 0x12F adds fixes for rare edge cases without measurable performance impact compared to 0x12B and recommends BIOS updates using Intel Default Settings to reduce risk.
- Intel extended warranties by two years for affected CPUs, advises timely BIOS updates, and notes microcode prevents crashes only in unaffected units while damaged CPUs require replacement.
