Intel will release a new patch to try to solve the stability problems of Intel Core Raptor Lake

When it seemed that the soap opera of instability and degradation of the 13th and 14th Generation Intel Core processors had come to an end with the release of the latest Intel Microcode updates, it is the company itself that revives it stating that Until now they had not found the root of the problem.

Intel now claims that the problem, dubbed “Vmin Shift” by the company itself, was in the clock circuit of the IA core with a design that makes it sensitive to degradation when high temperatures and voltages are applied to it and that they are already in a state of fix it.

This situation occurs in four scenarios detected by Intel with their corresponding “solutions” or mitigations.

1. Motherboard power delivery values ​​that exceed Intel guidelines. Here the company again blames motherboard manufacturers. The “mitigation” in this case is to leave the processor values ​​at those that Intel recommends by default.
2. The eTVB algorithm in the microcode allows the 13th and 14th generation Core i9 processors to maintain high-performance states even when they reach high temperatures. This situation can be mitigated with the 0x125 microcode that the company released in June of this year.
3. The SVID algorithm in the microcode requests high core voltages, which causes the problem to occur during idle or low-load periods. The “mitigation” would be the August 0x129 microcode that prevents these high voltage requests.
4. Microcode and BIOS requesting high voltages. In this case, the mitigation would come with a new microcode called 0x12B that includes the solutions of the two previous ones and solves this problem.

Therefore, Intel will release new updates together with motherboard manufacturers to integrate the microcode in new BIOS and solve, now definitively (hopefully), the problem that has caused crashes and degradations in the Raptor Lake and Raptor Lake Refresh processors.

On the other hand, they reaffirm that the 13th and 14th Generation processors for laptops are not affected, as well as Lunar Lake and the future Arrow Lake.
