Intel releases new patch to fix bugs in 13th and 14th generation CPUs

After releasing an update that alleviated the problems on 13th and 14th generation processors, Intel released a third microcode to fix the problem. The 0x12b patch aims to prevent possible damage to processors and fix malfunctions when using CPUs in idle mode or light tasks.

The new patch will solve this problem and stop sending insufficient power to the processor. Although the blue company does not state that this will actually be the last update that will end the whole situation, the expectation is that this update will solve the CPU energy issue.

It is worth remembering that the 0x12b patch alone does not eliminate the inconsistencies in the Raptor Lake and Raptor Lake Refresh processors, as users must update their motherboard with the 0x129 update released in August. If updates do not fix the problem, Intel has increased the CPU warranty and it is possible to replace the product if it is within the manufacturer’s recommended period.

Intel explains the origins of the malfunction

With the announcement of the 0x12b patch, Intel also announced that it revealed the origins of errors in the 13th and 14th generation processors. According to the company, the problem centers on Vmin Change Instability, which occurs in four specific cases.

First, the motherboard exceeds Intel’s recommended power limits. Secondly, the eTVB microcode allows certain CPUs of these generations to operate at high temperatures. The SVID microcode then demands high voltage for long periods of time, increasing the likelihood of instability. Finally, both the product microcodes and the motherboard BIOS require high voltage during idle mode or light activity.

All microcode released by Intel so far fixes at least one of these cases, such as the last 0x12b ending error. In fact, the company’s tests reveal that the new patch does not noticeably compromise the performance of the CPUs.

Intel is currently working with motherboard manufacturers to verify and release the new patch via BIOS. Brands such as MSI are already offering the update on their support pages.
