Latest BIOS Version
"1.Support for future Intel® Core™ Ultra series processors.2.Update AMI BIOS Codebase to version 5.32_9AACA_RC0D.00.05.10(6011.00)_213.3.Update Intel® ME firmware to version 19.0.5.2175v0.2 for enhanced platform stability.4.Update CPU Microcode to m_82_c0662_00000121 to improve processor performance and security.Updating this BIOS will simultaneously update the corresponding Intel ME to version 19.0.5.2175. The ME version will remain updated even if you roll back to an older BIOS later. We recommend using EZ Flash to update the BIOS, as it supports ZIP format and auto-updates the ME.If using USB BIOS FlashBack, ensure the ME version matches the BIOS version and rename the BIOS file with BIOSRenamer before proceeding. Before running the USB BIOS Flashback tool, please rename the BIOS file (A5575.CAP) using BIOSRenamer."
BIOS Release Notes Analysis
Launch Stability & Compatibility
The initial post-launch update, v0803, stabilizes the platform using Microcode 0x110 and resolves critical resource conflicts between integrated and discrete GPUs while fixing high-capacity DIMM compatibility. Firmware v1002 and v1004 integrate Microcode 0x112 to mitigate voltage regulation risks by disabling DLVR bypass mechanisms and enforce Intel Innovation Platform Framework and VT-d as default enabled settings. Further stabilizing the system, v1206 updates the Memory Reference Code (MRC) and integrates Microcode 0x114, which corrects Processor Power Management (PPM) logic to resolve frame-time spikes and latency issues in gaming workloads.
Feature Maturity & Hardware Support
Memory performance is significantly expanded in v1404 and v1601, which enable AEMP III to support high-speed CUDIMM configurations up to 7000MT/s and 256GB capacities. Version v1809 introduces DIMM Fit Pro for advanced memory training, while v2001 activates Intel 200S Boost to maximize frequency headroom on supported processors. Connectivity is enhanced in v1206, which enables Wi-Fi 7 (320MHz) and Wi-Fi 6E (6GHz) bands for compliant regions. Additionally, v1403 adds PCIe L1 Substates to refine link power management.
Critical Security & Power Management
Power efficiency is optimized in v1005 via Microcode 0x113, which adjusts Energy Performance Preference (EPP) grouping to improve core responsiveness within the Windows Balanced Power Plan. Update v1805 implements Microcode 0x117 to enhance signal integrity and enable DLRM states, reducing storage power consumption during idle periods. Long-term platform support is established in v3002, which updates the AMI BIOS codebase and integrates Microcode 0x121 to ensure compatibility and stability for future Intel Core Ultra processor steppings.
