Gigabyte B660M GAMING AC DDR4

Launch Stability & Compatibility

The platform lifecycle began with version vF1, followed by vF4 which resolved legacy VGA compatibility issues and corrected performance anomalies in Non-K CPUs. Support for the Intel Core i9-12900KS was established in vF5, while vF20 introduced full compatibility for Intel 13th Gen processors and improved DDR memory training. To ensure system stability during boot, vF22 addressed blank display occurrences specific to RTX 3060 series graphics cards. Additionally, vF21 optimized the resource allocation linkage between Resizable BAR and 4G decoding to enhance PCIe device compatibility.

Feature Maturity & Hardware Support

Firmware vF23 addressed critical vulnerabilities reported by Eclypsium Research and prepared the architecture for next-generation hardware. Integration with HWiNFO64 for real-time BIOS setting monitoring was enabled in vF24, while vF25 implemented SPD write protection to resolve JEDEC compliance issues with specific memory modules. The user interface was overhauled in vF26, which also integrated Microcode 0x11D. Security hardening continued in vF28, which mitigated LogoFAIL UEFI vulnerabilities and introduced options for GNA (Gaussian & Neural Accelerator) and SPD Write Disable.

Critical Security & Power Management

Version vF30 implemented Intel Default Settings and integrated Microcode 0x12B to address the root cause of Vmin Shift Instability by restricting elevated voltage requests during light-load states. Subsequent updates vF32c and vF32 introduced Microcode 0x12F to provide advanced mitigation against edge-case voltage drifts and Microcode 0x3A to resolve security alerts including INTEL-SA-01153. The security posture was further tightened in vF33 and vF34, which enabled Pre-boot DMA Protection, VT-d, and Secure Boot as system defaults, updated the CSME to version 16.1.38.2676v4.1, and added support for Intel 120/120F processors.
