Gigabyte Z790 D (rev. 1.0)

Launch Stability & Compatibility

The initial release vF1 establishes the baseline firmware for the Z790 platform. Subsequent update vF2 optimizes power delivery and CEP (Current Excursion Protection) settings to enhance system stability under load. This version also integrates the Intel APO (DTT) framework and enables support for the Intel Core i9-14900KS processor.

Feature Maturity & Hardware Support

Version vF3 introduces Intel Default Settings as the primary operational profile, requiring manual intervention to enable Gigabyte PerfDrive features. This update also adds EZ-OC support for specific co-branded memory modules. Hardware compatibility expands in vF5 with support for Intel 120/120F processors and the AI TOP Utility, alongside a CSME update to version 16.1.38.2676v4.1. Finally, vF6 improves memory compatibility for ADATA 6000 16G modules.

Critical Security & Power Management

To address processor degradation risks, vF3 integrates Microcode 0x12B, which encompasses the 0x125 eTVB algorithm fix and the 0x129 voltage clamp to mitigate Vmin Shift Instability. Further refinement arrives in vF4d[Beta] and the finalized vF4, which implement Microcode 0x12F to resolve edge-case voltage drifts and update Microcode 0x3A to patch security vulnerabilities including INTEL-SA-01153. Security enforcement tightens in vF5, which enables Pre-boot DMA Protection, VT-d, and IOMMU by default, while vF6 establishes Secure Boot as the system default.
