Gigabyte B650 GAMING X AX (rev. 1.3)

Launch Stability & Compatibility

The initial firmware release vFB establishes baseline system stability using AGESA 1.0.0.6, which implements critical voltage restrictions on the VDDCR_SOC rail to prevent thermal damage. Subsequent update vFC integrates AGESA 1.0.0.7c, significantly improving DDR5 memory training algorithms to support high-speed modules (6400MT/s+) and resolving boot failures associated with Samsung-based kits. Early security hardening is addressed in vFA2, which updates the codebase to AGESA 1.1.0.1 to mitigate the LogoFAIL vulnerability, preventing malicious code execution during the DXE boot phase.

Feature Maturity & Hardware Support

Support for next-generation Ryzen 9000 (Zen 5) processors is enabled in vFB1 via AGESA 1.1.7.0. Version vFB2 introduces Curve Shaper (AGESA 1.2.0.0a), allowing for distinct undervolt curves across different temperature and frequency states, while vFB3b adds a one-click 105W TDP mode to unlock additional CPU performance. Optimization for Ryzen 9000X3D series processors is refined in vFB3d through AGESA 1.2.0.2a, which introduces X3D Turbo Mode to optimize thread scheduling and CCD parking logic. Extended support for future architecture revisions is established in vFC1 with the integration of AGESA 1.2.8.0.

Critical Security & Power Management

Firmware vFB3a integrates AGESA 1.2.0.1a to patch the high-severity Sinkclose vulnerability, preventing SMM Lock Bypass attacks. Version vFB4 addresses CVE-2024-36347, correcting a microcode signature verification flaw, while vFB6 (AGESA 1.2.0.3e) resolves the TPM Out-of-Bounds Read vulnerability (CVE-2025-2884). Finally, update vFC1 mitigates the critical Hynix Rowhammer vulnerability (CVE-2025-6202) affecting specific DDR5 modules, ensuring data integrity under high-load scenarios.
