System Stability & Architecture
The B860 platform launched with version FA, establishing initial hardware support. Version FA2 integrates Intel MR1 ingredients and Microcode 0x116, which improves voltage regulation specifically for non-K Core Ultra SKUs and introduces the Resource Priority Feature. This update also optimizes memory compatibility and resolves graphical rendering issues within the BIOS Advanced mode interface. Version FBb[Beta] subsequently updates to Microcode 0x117, enhancing signal integrity for high-speed CUDIMM DDR5 memory and enabling DLRM state for storage power savings.
Performance Tuning & Latest Features
Version FA3b[Beta] incorporates Microcode 0x118 (MR3) to stabilize Ultra Turbo Mode performance profiles and adds support for V-Color OLED memory modules. The stable release, version FA3, further hardens security by enabling Pre-boot DMA Protection, VT-d, and IOMMU by default, alongside support for the AI TOP Utility v4.1.1. Most recently, version FA4 prepares the motherboard for Core Ultra 2-series refresh processors via Microcode 0x11b and enforces Secure Boot as the default system configuration.
