MSI X470 GAMING PLUS MAX

Launch Stability & Compatibility

Initial firmware updates focused on stabilizing the AM4 platform and rectifying early performance anomalies. Version vH2 integrates AGESA 1.0.0.3abba to resolve core frequency behavior, allowing Ryzen 3000 series processors to correctly reach advertised turbo speeds. Boot initialization and NVMe device compatibility were optimized in vH3, while vH5 resolves HDMI audio signal loss on specific AMD RX570 configurations. The transition to the ComboV2 codebase began with vH9, and vHC (AGESA 1.2.0.2) provides critical mitigations for USB connectivity dropouts on 500-series chipsets.

Feature Maturity & Hardware Support

Mid-cycle updates expanded processor support and refined system responsiveness. Version vHE (AGESA 1.2.0.6c) enables official support for the Ryzen 7 5800X3D, ensuring proper L3 V-Cache utilization. This was followed by vHG (AGESA 1.2.0.7), which eliminates fTPM Stuttering in Windows by correcting TPM key validation latency. Advanced tuning capabilities arrived in vHH1[Beta] (AGESA 1.2.0.8), unlocking native Curve Optimizer support for the 5800X3D. Subsequent update vHJ integrates AGESA 1.2.0.B to mitigate the Inception speculative side-channel vulnerability while adding support for newer Ryzen 5000 series SKUs.

Critical Security & Power Management

Recent firmware prioritizes hardening the platform against high-severity exploits and finalizing system management functions. Version vHK (AGESA 1.2.0.Ca) addresses the LogoFAIL image parsing vulnerability and patches CVE-2024-36877. The critical Sinkclose SMM lock bypass is resolved in vHL1[Beta] (AGESA 1.2.0.Cc). Maintenance update vHM (AGESA 1.2.0.F) fixes a bug where fan curves failed to persist after exiting the BIOS without saving. Finally, versions vHN1 through vHN2[Beta] update the TPM firmware to enhance compatibility with modern Anti-Cheat systems, necessitating BitLocker key backups prior to installation.
