MSI B350 GAMING PRO CARBON

Launch Stability & Compatibility

Initial platform stability is established across versions v10 through v13, addressing early memory training parameters and correcting PCI-E hot-plug functionality. Update v14 integrates AGESA 1.0.0.6, optimizing memory controller performance for first-generation Ryzen processors. Version v15 expands hardware support by enabling "Above 4G Decoding" for high-capacity GPU resource mapping and reducing POST times for systems utilizing Intel 600P NVMe storage. Subsequent update v1B prepares the platform for Ryzen 2000 series processors via AGESA 1.0.0.1a while retaining legacy compatibility for Windows 7 environments.

Feature Maturity & Hardware Support

Mid-lifecycle updates v1F through v1H focus on stabilizing Raven Ridge and Bristol Ridge APU performance, with v1F implementing AGESA 1.0.0.6 to support SATA hot-plug capabilities. A significant architectural shift occurs in v1L2[Beta], which transitions the firmware to the AGESA ComboAm4v2PI 1.2.0.7 codebase. This critical update resolves the fTPM Stuttering issue caused by key validation latency in Windows 10/11 and modifies default Secure Boot behavior. Note that v1L2[Beta] and later versions permanently remove support for Bristol Ridge APUs to accommodate the expanded code size of newer AGESA libraries.

Critical Security & Power Management

Recent firmware releases prioritize hardening the platform against privilege escalation vulnerabilities. Version v1L3[Beta] updates to AGESA 1.2.0.A to mitigate TPM Out of Bounds access risks. Security patching continues in v1L4[Beta], which resolves the specific vulnerability tracked as CVE-2024-36877. Update v1L5[Beta] integrates AGESA 1.2.0.Cc, delivering the essential microcode fix for the Sinkclose (SMM Lock Bypass) exploit. The latest update, v1L7[Beta], deploys AGESA 1.2.0.F, which upgrades fTPM firmware to ensure robust compatibility with modern Anti-Cheat software and Windows 11 security requirements.
