Launch Stability & Compatibility

Initial firmware F1 optimizes system boot times and improves RAID function compatibility. Version F2 updates the platform to AGESA 1.0.0.6 to support 3rd Gen Ryzen XT processors while mitigating SMM Callout Privilege Escalation vulnerabilities. The transition to the ComboV2 codebase in version F60 (AGESA 1.2.0.0) enables Smart Access Memory and full support for Ryzen 5000 series processors, with subsequent update F61 expanding compatibility to Ryzen 5000 G-Series APUs via AGESA 1.2.0.3 B.

Feature Maturity & Hardware Support

Update F62 transitions to AGESA 1.2.0.5, introducing Capsule BIOS protection and enabling fTPM by default to meet Windows 11 requirements. Version F63 integrates AGESA 1.2.0.7, which resolves widespread fTPM Stuttering issues affecting system latency. Firmware F64 upgrades to AGESA 1.2.0.8 to optimize performance for the Ryzen 7 5800X3D and patches specific download assistant vulnerabilities identified by Eclypsium Research.

Critical Security & Power Management

Version F66 (AGESA 1.2.0.B) hardens the UEFI against the LogoFAIL image parsing vulnerability. Update F67d incorporates AGESA 1.2.0.Cc to mitigate the high-severity Sinkclose exploit (SMM Lock Bypass). Version F67g (AGESA 1.2.0.E) resolves the microcode signature verification flaw CVE-2024-36347. The final release F67 consolidates AGESA 1.2.0.F updates and fixes a critical TPM 2.0 out-of-bounds read vulnerability (CVE-2025-2884).
