Latest BIOS Version
"1. Enhance overall system security.2. pdate 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 (SZ790E.CAP) using BIOSRenamer."
BIOS Release Notes Analysis
Launch Stability & Compatibility
Initial firmware revisions focused on establishing platform baseline stability and expanding memory density support. Version 0703 resolved critical driver compatibility issues affecting NVIDIA RTX40 series graphics cards. Memory compatibility saw significant scaling, with v0813 enabling support for non-binary 24GB/48GB modules and v0904 validating high-speed DDR5-7200 kits. Support for Intel Core 14th Gen processors was introduced in v1202 and refined via Microcode updates in v1402. Additionally, v1202 addressed instability when configuring RAID arrays on high-capacity storage subsystems.
Feature Maturity & Hardware Support
Mid-cycle updates prioritized memory capacity maximization and adherence to Intel power specifications. Version 1904 expanded total system memory support to 256GB. To address performance constraints on non-K 14th Gen processors, v2002 integrated Microcode 0x123, allowing the disabling of CEP (Current Excursion Protection) to optimize throughput. The firmware evolved to enforce strict power limits, starting with the Intel Baseline Profile in v2202. This culminated in v2301, which implemented Intel Default Settings (Performance/Extreme) and redefined the F5 "Reset to Defaults" behavior to align with Intel's recommended power envelopes.
Critical Security & Power Management
Later revisions focused on mitigating hardware-level vulnerabilities and stabilizing voltage regulation. Version 1801 patched the LogoFAIL security vulnerability. A sequence of microcode updates addressed processor degradation risks: v2402 applied Microcode 0x125 to correct eTVB algorithm errors, while v2503 integrated Microcode 0x129 to clamp maximum VID requests to 1.55V. Version 2703 deployed Microcode 0x12B to resolve the root cause of Vmin Shift Instability by addressing elevated voltages during light loads; this update initially forced the C1E power state enabled, though v2801 restored the ability to toggle C1E. Long-term stability was further reinforced in v3001 with Microcode 0x12F for advanced Vmin mitigation, followed by v3107 which updated the ME Firmware to 16.1.38.2676 for general security hardening.
