Gigabyte B650 UD AC (rev. 1.0)

Launch Stability & Compatibility

The firmware lifecycle begins with vF1 establishing baseline system functionality on AGESA 1.1.0.1, which is immediately patched in vF2 to mitigate the critical LogoFAIL vulnerability that allowed malicious code execution during the boot phase. Support for Ryzen 8000 series APUs is refined in vF4 via AGESA 1.1.0.2 b, which disables STAPM defaults to stabilize power management. Transitioning to next-generation architecture, vF30 and vF31a integrate AGESA 1.1.7.0 Patch A to enable initial compatibility for Ryzen 9000 'Granite Ridge' processors, while vF31a specifically tunes Precision Boost Overdrive (PBO) algorithms to optimize thermal performance.

Feature Maturity & Hardware Support

Update vF31 advances the platform to AGESA 1.2.0.0a, introducing Curve Shaper technology to allow distinct undervolting across temperature and frequency states for Zen 5. Optimization for X3D processors accelerates in vF32c through vF32f (AGESA 1.2.0.2a), which implement X3D Turbo Mode and refine CCD parking logic to reduce latency in gaming workloads. This trajectory continues in vF32g and vF32 (AGESA 1.2.0.2b), adding "Zen5 Gaming Optimizations" and patching SMM vulnerabilities. Further enhancements for 2CCD Ryzen 7000 and 9000 CPUs arrive in vF33a and vF33b (AGESA 1.2.0.3a), requiring updated chipset drivers to fully leverage cross-CCD gaming performance improvements.

Critical Security & Power Management

Major security hardening is implemented in vF32a, which integrates AGESA 1.2.0.1a to mitigate the high-severity Sinkclose vulnerability (SMM Lock Bypass). Subsequent updates address specific CVEs: vF33 resolves the AMD CPU microcode signature verification flaw (CVE-2024-36347), while vF35 (AGESA 1.2.0.3e) patches the TPM Out-of-Bounds Read vulnerability (CVE-2025-2884). The lifecycle extends to future hardware in vF38, which updates to AGESA 1.2.8.0 to support next-generation processors and fixes the critical Hynix Rowhammer vulnerability (CVE-2025-6202) affecting specific DDR5 modules.
