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 (SZ690E.CAP) using BIOSRenamer."
BIOS Release Notes Analysis
Launch Stability & Compatibility
The firmware lifecycle for the Z690 platform began with foundational stability updates in v0503, followed quickly by v1403 which enabled support for the Intel Core i9-12900KS. Support for 13th Gen Intel processors was established in v1720 and refined in v2103, which also mandated a critical Management Engine (ME) update to v16.1.25.1885 that restricts rollback to ensure signal integrity. Memory compatibility saw a significant upgrade in v2204, enabling support for non-binary 24GB and 48GB DDR5 modules. Storage configuration was improved in v2602 to resolve instability in high-capacity RAID arrays, while v3101 introduced PCIe Bifurcation options to support M.2 storage on GPU lanes.
Feature Maturity & Hardware Support
Firmware v2802 finalized support for 14th Gen Intel Core processors, updating the ME firmware to v16.1.30.2264. Security hardening in v3101 patched the LogoFAIL vulnerability. Performance tuning for 14th Gen non-K SKUs was introduced in v3302 via Microcode 0x123, which allows disabling Current Excursion Protection (CEP) to optimize throughput at the cost of higher thermal loads. As power management standards evolved, v3501 and v3603 implemented Intel Default Settings, redefining factory defaults to strictly adhere to Intel's power limits and introducing the "Performance Preferences" menu to distinguish between ASUS Advanced OC profiles and standard power baselines.
Critical Security & Power Management
A series of critical updates addresses Vmin Shift Instability in 13th and 14th Gen processors. Version 3701 integrates Microcode 0x125 to correct eTVB algorithms, preventing boosts beyond safe thermal limits. Subsequently, v3802 applies Microcode 0x129 to enforce a 1.55V voltage clamp to prevent physical degradation. The root cause of voltage drift during idle states is mitigated in v3901 and v4001 via Microcode 0x12B, which also temporarily enforced C1E states (a restriction lifted in v4101). Long-term stability is further reinforced in v4301 with Microcode 0x12F to address edge-case voltage drifts and "Always On" degradation risks, culminating in v4505 which updates the ME Firmware to 16.1.38.2676.
