MSI B450M GAMING PLUS

Launch Stability & Compatibility

The firmware lifecycle begins with the initial release in v10, followed immediately by v11 which integrates AGESA 1.0.0.4C to stabilize DDR4 memory training. Update v12 upgrades the codebase to AGESA 1.0.0.6, finalizing support for Summit Ridge and Pinnacle Ridge architectures while enabling SATA hotplug functionality. Subsequent iterations v13 and v14 focus on refining compatibility for Raven Ridge APUs and further optimizing memory signal integrity, while v16 prepares the platform for the transition to next-generation processors.

Feature Maturity & Hardware Support

Update v17 marks a major architectural shift, implementing ComboPI 1.0.0.3ab to support Ryzen 3000 series processors and transitioning the interface to GSE-Lite mode. Critical performance corrections arrive in v1A, which deploys AGESA 1.0.0.3abba to resolve boost clock frequency deficits on Zen 2 CPUs. Version v1B (ComboPI 1.0.0.4 Patch B) reduces system boot times and improves PCIe device enumeration, while v1C updates the codebase to AGESA 1.0.0.6 to ensure mature platform stability before the introduction of ComboV2 firmware.

Critical Security & Power Management

Update v1G integrates AGESA 1.2.0.7 to permanently resolve fTPM Stuttering caused by key validation latency in Windows environments. Security hardening continues in v1H1[Beta] with AGESA 1.2.0.A, addressing TPM out-of-bounds access risks. Version v1H2[Beta] advances to AGESA 1.2.0.Ca, mitigating the LogoFAIL image parsing vulnerability and fixing CVE-2024-36877. The firmware addresses the high-severity Sinkclose SMM lock bypass exploit in v1H3[Beta] via AGESA 1.2.0.Cc. Finally, v1H5[Beta] implements AGESA 1.2.0.F, updating TPM firmware to enhance compatibility with modern anti-cheat systems.
