Latest BIOS Version
"Update Intel microcode for enhanced stability & security.Updating this BIOS will simultaneously update the corresponding Intel ME to version 16.1.40.2765. Please note after you update this BIOS, the ME version remains the updated one even if you roll back to an older BIOS later. "
BIOS Release Notes Analysis
Launch Stability & Compatibility
The firmware lifecycle for the Z790-P WIFI D4 began with foundational updates to the Intel Management Engine (ME), starting with v0602 and v0805, to establish platform baselines. Memory compatibility was significantly improved in v0809, addressing early training issues. Update v1205 expanded architecture support to include Intel 14th Gen processors while simultaneously resolving instability when configuring RAID arrays on high-capacity storage. Early security hardening was implemented in v1220 to address potential vulnerabilities alongside further ME firmware synchronization.
Feature Maturity & Hardware Support
Mid-cycle updates focused on hardware expansion and performance tuning. Version 1402 formalized microcode support for 14th Gen CPUs, while v1603 and v1611 introduced support for specialized hardware, including graphics cards with M.2 storage and USB4 PCIe Gen4 add-in cards. Critical security patching occurred in v1604 to mitigate the LogoFAIL vulnerability. Performance customization evolved with v1641, which integrated Microcode 0x123 to allow users to disable CEP (Current Excursion Protection) on non-K processors. Subsequently, v1656 and v1658 redefined power management by implementing the Intel Baseline Profile and Intel Default Settings, standardizing factory power limits to ensure operational stability.
Critical Security & Power Management
The latest firmware revisions prioritize mitigating voltage-related degradation in Raptor Lake processors. Update v1661 integrated Microcode 0x125 to correct eTVB algorithm errors that allowed unsafe frequency boosts. This was followed by v1663, which deployed Microcode 0x129 to enforce a hard voltage clamp, preventing requests above 1.55V. Update v1802 addressed the root cause of Vmin Shift Instability via Microcode 0x12B, which resolves elevated voltage requests during idle states, and permanently enabled C1E to reduce processor stress. Further mitigation against voltage drift was applied in v1820 with Microcode 0x12F. Finally, v1825 consolidated system security and updated the Management Engine to version 16.1.35.2557.
