Gigabyte B650 Gaming X (rev. 1.3)

Launch Stability & Compatibility

The initial firmware release, vFB, establishes the platform baseline using AGESA 1.0.0.6, which implements early voltage restrictions on the VDDCR_SOC rail to prevent hardware damage. Memory compatibility is significantly refined in vFC via AGESA 1.0.0.7c, enabling support for high-speed DDR5 modules (6400MT/s+) and resolving boot failures associated with Samsung-based kits. Security hardening is prioritized in vFA2, which integrates AGESA 1.1.0.1 to patch the critical LogoFAIL vulnerability, preventing malicious boot logos from executing code during the DXE phase.

Feature Maturity & Hardware Support

Support for Ryzen 9000 'Granite Ridge' processors is introduced in vFB1 with AGESA 1.1.7.0. Subsequent optimization in vFB2 (AGESA 1.2.0.0a) enables Curve Shaper, allowing for distinct undervolt curves across different temperature states. Security is further tightened in vFB3a with AGESA 1.2.0.1a, which mitigates the high-severity Sinkclose vulnerability (SMM Lock Bypass). Performance tuning peaks in vFB3d and vFB3e, utilizing AGESA 1.2.0.2a to introduce X3D Turbo Mode and optimize thread scheduling for Ryzen 9000X3D series processors.

Critical Security & Power Management

Version FB3g updates the firmware to AGESA 1.2.0.2b, patching critical SMM vulnerabilities (AMD-SB-7027). Gaming performance for dual-CCD Ryzen 7000 and 9000 CPUs is enhanced in vFB3i via AGESA 1.2.0.3a, while vFB4 addresses the AMD CPU microcode signature verification vulnerability (CVE-2024-36347). Version FB6 integrates AGESA 1.2.0.3e to fix the TPM 2.0 Out-of-Bounds Read flaw (CVE-2025-2884). Finally, vFC1 prepares for next-generation processors with AGESA 1.2.8.0 and mitigates the critical Hynix Rowhammer vulnerability (CVE-2025-6202) affecting specific DDR5 modules.
