BIOS Update Status
- Microcode 0x129
Microcode update 0x129 addresses an issue where the processor may request high voltages, potentially leading to accelerated degradation.
- Microcode 0x12B
Microcode update 0x12B addresses elevated voltage requests by the processor during idle and/or light activity periods (includes 0x129).
- Microcode 0x12F
Microcode update 0x12F to further address processor degradation on systems with light activity.
Latest BIOS Version
"1.Enhance overall system security.2.Update the ME Firmware version to 16.1.38.2676.Updating this BIOS will simultaneously update the corresponding intel ME to version 16.1.38.2676. Please note after you update this BIOS, the ME version remains the updated one even if you roll back to an older BIOS later.Before running the USB BIOS Flashback tool, please rename the BIOS file (SZ690A.CAP) using BIOSRenamer."
BIOS Release Notes Analysis
Launch Stability & Compatibility
The firmware lifecycle began with v0811, rapidly addressing initial platform stability and Windows 11 performance by v1003, which also updated the USB PD firmware to 1.0F. Support for the Intel Core i9-12900KS was established in v1403 alongside Management Engine (ME) updates. A major architectural transition occurred between v1720 and v2103, enabling support for 13th Gen Intel Core processors and optimizing overclocking stability. High-capacity memory compatibility was finalized in v2204, introducing support for non-binary 24GB and 48GB DDR5 modules.
Feature Maturity & Hardware Support
Support for 14th Gen Intel Core processors was integrated in v2602 and refined in v2802, which also resolved RAID configuration issues for high-capacity storage. Critical security patching arrived in v3101 to mitigate the LogoFAIL vulnerability, while simultaneously adding PCIe Bifurcation support for GPU/storage configurations. Performance tuning capabilities expanded in v3302 with Microcode 0x123, allowing users to disable CEP (Current Excursion Protection) on non-K processors, and extending memory support to 256GB. By v3603, the BIOS formally adopted Intel Default Settings to standardize power profiles and thermal limits across supported CPUs.
Critical Security & Power Management
Later updates focused heavily on mitigating voltage-related instability in Raptor Lake processors. Version 3701 implemented Microcode 0x125 to correct eTVB algorithms, followed by v3802 with Microcode 0x129 to clamp maximum VID requests. The root cause of Vmin Shift Instability was addressed in v3901 and v4001 via Microcode 0x12B, which mitigated elevated voltage requests during idle states and enforced C1E power states. Advanced protection against degradation was deployed in v4301 with Microcode 0x12F, while v4505 concluded the cycle with general security enhancements and ME Firmware 16.1.38.2676.
