Microcode 0x12B “addresses elevated voltage requests by the processor during idle and/or light activity periods.”

Root cause identified, but it's taken the better part of a year After what has felt like an eternity, Intel reckons it has finally identified why its 13th and 14th Gen Core series desktop processors have been so unstable.

The new microcode also contains the previous updates, so it could be the last update users will have to apply for this issue.
