Gigabyte Z790 S WIFI DDR4 (rev. 1.1/1.2)

Launch Stability & Compatibility

The Z790 S WIFI DDR4 platform launched with version F1, establishing initial system baselines. Version F2 optimizes power delivery by refining CEP (Current Excursion Protection) settings and enables support for the Intel Core i9-14900KS processor. This update also upgrades the Intel APO framework to version 9.0.11405.42569 to enhance thread scheduling. Version F3 standardizes system configuration by enforcing Intel Default Settings as the mandatory baseline, requiring manual intervention to access custom performance profiles.

Feature Maturity & Hardware Support

Hardware compatibility expands in version F3 with the addition of EZ-OC support for co-branded AORUS x XPG DRAM modules. Version F6 introduces CPU support for Intel 120 and 120F series processors and integrates compatibility for the AI TOP Utility v4.1.1. Memory validation is further refined in version F7, which updates support for KingBank 3200MHz modules utilizing JHICC chips. Additionally, version F6 updates the CSME firmware to 16.1.38.2676v4.1 to ensure management engine stability.

Critical Security & Power Management

To address processor degradation risks, version F3 integrates Microcode 0x12B, serving as the root cause mitigation for Vmin Shift Instability by managing elevated voltage requests during idle states. This protection is advanced in versions F5c and F5 via Microcode 0x12F, which targets edge-case voltage drifts, alongside Microcode 0x3A to resolve security vulnerabilities including INTEL-SA-01153 and INTEL-SA-01224. Platform hardening continues in version F6 by enabling Pre-boot DMA Protection, VT-d, and IOMMU by default, while version F7 establishes Secure Boot as the factory default state.
