**San Francisco, CA** – After months of investigation, Intel has pinpointed the root cause of instability issues affecting its 13th and 14th generation processors. The problem stemmed from a clock tree circuit within the processor core itself, which failed under high voltage and temperature conditions. This failure resulted in a shift in the clock duty cycle, leading to system instability.

Intel has identified four key factors contributing to the issue:

* **Excessive voltage:** Motherboards providing more voltage than recommended by Intel.
* **Aggressive boosting:** The eTVB microcode algorithm allowed the CPUs to boost into high-performance states even at high temperatures.
* **High voltage requests:** The SVID microcode algorithm requested higher voltages at certain frequencies than the silicon could handle.
* **Elevated voltages during idle:** Microcode and BIOS settings requested elevated voltages during idle or light workloads.

To address these issues, Intel has released a second microcode update, version 0x12B, which builds upon previous updates 0x125 and 0x129. 0x12B enforces stricter voltage control during idle and light activity periods.

Motherboard manufacturers are currently working to integrate the 0x12B microcode via upcoming BIOS updates, a process that could take several weeks. While this microcode prevents the instability issue from occurring, it cannot fix CPUs already affected. Those CPUs will need to be replaced under Intel’s extended warranty program.

Intel assures users that the 0x12B patch will not significantly impact performance and that mobile CPUs, as well as upcoming Lunar Lake and Arrow Lake desktop parts, are not affected by this flaw.

**This new update marks a significant step towards resolving the instability issues plaguing Intel’s latest generation processors. Users are advised to update their BIOS as soon as it becomes available to ensure optimal performance and stability.**
