Intel Releases Critical Microcode Fix for 13th and 14th Gen CPU Voltage Issues
Thursday September 26, 2024. 05:35 PM , from Slashdot
Intel has released microcode update 0x12B for its 13th and 14th generation Core processors, addressing persistent stability issues stemming from voltage irregularities. The update targets a specific clock tree circuit within the CPU's IA core that was causing elevated voltage requests during idle and light workloads.
The company identified four key factors contributing to voltage instability: motherboards exceeding Intel's power specifications, an Enhanced Thermal Velocity Boost algorithm allowing sustained high performance at elevated temperatures, frequent high voltage requests from the processor, and problematic microcode demanding elevated core voltages during low-activity periods. While previous update 0x129 addressed some concerns, the new 0x12B update aims to resolve the root cause of the 'Vmin shift' problem, where voltage spikes lead to increased power requirements and potential degradation over time. Intel is working with motherboard manufacturers to roll out BIOS updates incorporating the new microcode. Read more of this story at Slashdot.
