The 13th/14th generation Core CPU is still being patched up: Intel releases 0x12F microcode update

Fast Tech May 8th news, Intel released the 0x12B microcode update in September last year to solve the Vmin Shift instability problem of the 13th/14th generation Core desktop processor. Although this update has greatly reduced the number of reports of related issues, the problem has not been completely solved. To further improve the problem, Intel recently released a new 0x12F microcode update. The 0x12F microcode update is a supplement to 0x12B, mainly for systems that run continuously for multiple days under low load and low active level conditions. Intel said that this update will not have a measurable impact on processor performance and will not change its opinion on the root cause of the Vmin Shift problem. Intel continues to recommend that users install the latest version of the BIOS and use the default configuration file to reduce the risk of instability issues. The 0x12F microcode update is for 13th and 14th generation Core processors, but not for the latest Core Ultra 200S series processors, which have not been found to have similar issues. Previously, some Raptor Lake chips, especially K series chips, have experienced accelerated wear and even CPU failure due to extreme pressure on the clock tree circuit of the internal IA core, as well as excessive voltage and temperature. Currently, some main board manufacturers have started to release BIOS updates containing the 0x12F microcode update. Raptor Lake users will soon be able to get this new microcode update by updating the BIOS.
