MSI B450 Gaming Plus

Launch Stability & Compatibility

The firmware lifecycle begins with v10 and immediate memory stabilization in v11 via AGESA 1.0.0.4C. Updates v12 through v17 expand processor compatibility to include Athlon 200GE and Raven Ridge architectures. A major architectural shift occurs in v19, which integrates ComboPI 1.0.0.3ab to enable support for Ryzen 3000 series CPUs; this update necessitates a transition to the Click BIOS (GSE-Lite) interface to accommodate the larger firmware payload. Version v1A further refines this transition by adding Overclocking Profiles and improving memory training for the new processor generation.

Feature Maturity & Hardware Support

Performance optimization drives the mid-cycle updates, with v1C implementing AGESA 1.0.0.3abba to resolve boost clock frequency scaling issues on Ryzen 3000 processors. Version v1D (AGESA 1.0.0.4 Patch B) accelerates system boot times and enhances PCIe device compatibility. The firmware matures with v1E, updating to AGESA 1.0.0.6 to finalize support for earlier Ryzen generations and fixing HDMI audio loss on RX570 GPUs. Update v1I marks a significant stability milestone by integrating AGESA 1.2.0.7, which eliminates fTPM-induced stuttering in Windows and enables Secure Boot by default.

Critical Security & Power Management

Recent development focuses on hardening platform security against advanced threats. Version v1J1[Beta] updates to AGESA 1.2.0.A to patch TPM out-of-bounds access risks. Subsequent releases address high-severity vulnerabilities: v1J4[Beta] (AGESA 1.2.0.Ca) mitigates LogoFAIL and CVE-2024-36877, while v1J5[Beta] (AGESA 1.2.0.Cc) patches the Sinkclose SMM lock bypass. The roadmap extends into 2025 with v1J8[Beta], which deploys AGESA 1.2.0.F to update fTPM firmware for enhanced anti-cheat compatibility and system stability.
