BIOS Release Notes Analysis
Launch Stability & Compatibility
The initial firmware release v2.02 establishes baseline platform functionality and memory training algorithms. Security is prioritized in v2.06.AS03[Beta], which updates the AGESA to 1.1.0.2.2 to patch the critical LogoFAIL vulnerability, preventing malicious payloads from executing during the DXE boot phase. Subsequent stability adjustments in v2.08 (AGESA 1.1.0.2b) disable STAPM (Skin Temperature Aware Power Management) on Phoenix AM5 processors to prevent aggressive thermal throttling, while v2.10 updates the codebase to AGESA 1.1.0.3 to align with AMD reference code.
Feature Maturity & Hardware Support
Support for Ryzen 9000 (Zen 5) 'Granite Ridge' processors is enabled in v3.01 via AGESA 1.1.7.0. Feature capabilities are expanded in v3.06 with AGESA 1.2.0.0a, which introduces Curve Shaper to allow distinct undervolting curves based on temperature and frequency states. Version v3.08 (AGESA 1.2.0.2) addresses architecture-specific performance by optimizing core-to-core communication to reduce latency and introducing a 105W TDP configuration option. Specific optimizations for X3D architectures are implemented in v3.10 (AGESA 1.2.0.2a) and v3.12.AS02[Beta], which enables Ryzen 7 9800X3D overclocking and adds a dedicated Gaming Mode. Support for high-end Ryzen 9 9000X3D processors is formalized in v3.18.AS02[Beta] through AGESA 1.2.0.3a.
Critical Security & Power Management
Later revisions focus on hardening system security and refining power delivery. Version v3.15 updates to AGESA 1.2.0.2b to patch critical SMM vulnerabilities (AMD-SB-7027) and improve sleep state transitions. Boot initialization failures affecting specific Ryzen 9000 series SKUs are resolved in v3.20. Update v3.30 integrates AGESA 1.2.0.3e to mitigate the TPM Out-of-Bounds Read vulnerability (CVE-2025-2884) and further refine voltage safety limits. Following PBO and memory stability improvements in v3.40 and v3.50, the firmware roadmap advances to v4.03 (AGESA 1.2.7.1), which updates the PSP firmware and enables preliminary support for next-generation 2026 processors.
