But microcode update can't fix CPUs that are already crashing or unstable.

apparently intel has finally figured out why 13th and 14th gen CPU are failing. the issue is mainly caused by a faulty microcode algorithm, which causes the CPU requesting more voltage than it needs and results in oxidation issues within the chip itself.

CPU’s that do not show any symptoms yet could be saved by a microcode update, but there is no real hope for those that already started to rust away
