MSI BIOS Version Latest Update Guide for Stability & Safety

BIOS (Basic Input/Output System) is a small firmware that acts as a bridge between your motherboard and hardware. It is the first code executed when your system powers on, and it initializes all hardware before the operating system (like Windows) starts loading.

Premium motherboard manufacturers like MSI provide custom BIOS for their boards, which include extra features, overclocking options, memory profiles, and hardware compatibility improvements.

In simple words: BIOS is the “brain” of your PC that ensures all components communicate and work together properly.

Role of BIOS Updates (Performance, Stability, Compatibility)

MSI BIOS updates are not just minor fixes; they can significantly impact your system’s performance and reliability.

Key reasons to update BIOS include:

1. Performance Improvements:
   • Optimized support for new CPUs or RAM for better speed and efficiency.
2. Stability Fixes:
   • Resolves boot failures, system crashes, and memory instability issues.
3. Security & Bug Fixes:
   • Patches critical vulnerabilities in firmware or CPU microcode.
4. New Hardware Support:
   • Enables official support for new-generation CPUs, GPUs, or high-speed RAM modules.

In short, updating BIOS not only ensures new hardware works properly but also keeps your system stable and secure.

MSI BIOS Update – December 2025

Did an Update Come This Month?

Yes! In December 2025, MSI released a new BIOS update for select motherboards. While updates are usually rolled out monthly or quarterly, this particular release has caught attention because it includes critical fixes and hardware support, but some users have reported minor stability issues.

In short: The update is available, but its adoption should be cautious, especially for daily-use or production PCs.

Which Platforms / Series Were Targeted?

The December 2025 BIOS update primarily focused on:

• AMD AM5 800-series motherboards – These boards received the latest AGESA firmware update, improving memory compatibility and future CPU support.
• Intel Z790/Z690 series – Some updates were released to enhance stability and fix minor bugs, particularly for 13th and 14th Gen Intel CPUs.

Not all MSI motherboards received this update. Users should check their exact motherboard model on MSI’s official site before proceeding.

AGESA Version

For AMD boards, this update uses AGESA v1.2.8.0. In simple terms:

• AGESA is AMD’s microcode framework for CPU and memory initialization.
• Updating to AGESA v1.2.8.0 ensures better RAM compatibility, fixes minor stability issues, and prepares the system for future CPUs.
• However, some early users reported boot issues or BIOS access problems, so the update is stable only on tested boards.

Think of AGESA as the “engine” behind AMD CPUs: updating it can improve performance, but flashing the wrong version can cause system issues.

What’s New in This MSI BIOS Update

Memory Compatibility Improvements

One of the major highlights of the December 2025 BIOS update is enhanced memory support. This includes:

• Better compatibility with high-speed DDR5 modules
• Improved XMP profile detection and stability
• Fixes for RAM-related crashes or instability experienced in previous BIOS versions

Simply put, users can expect smoother memory performance, especially on high-frequency kits.

CPU Support / Microcode Changes

The update also brings new CPU support and microcode improvements:

• AMD AM5 motherboards now support additional future CPUs without stability issues
• Intel Z790/Z690 boards received microcode fixes for 13th and 14th Gen CPUs
• Minor performance optimization for certain processor workloads

Updating the BIOS ensures your system can run the latest CPUs efficiently and securely.

Stability & Boot-Related Changes

• Many previous BIOS versions faced boot delays or rare crashes on certain configurations
• This update addresses boot loops, CMOS reset problems, and system freezes
• Users may notice a smoother POST (Power-On Self-Test) sequence

Minor UI / Firmware Level Optimizations

• Improved BIOS interface navigation and responsiveness
• Enhanced hardware monitoring tools in BIOS
• Better firmware-level optimization for fan curves, voltage control, and temperature reporting

These may not affect daily performance drastically, but they improve user experience and system tuning options.

Affected Motherboards (Availability)

Which Series Received the Update?

The December 2025 BIOS update primarily targets:

• AMD AM5 800-series motherboards (e.g., MPG X870E Edge Ti, MAG B850M Mortar)
• Select Intel Z790/Z690 series boards

Did All Boards Receive It?

• No, the rollout is limited to specific models first
• Other boards may receive a stable build later after internal testing

Why Is the Rollout Gradual?

• Manufacturers like MSI test BIOS on a small set of boards to ensure stability
• Gradual rollout reduces risk of widespread boot failures or compatibility issues
• Users are advised to check their motherboard model and download the correct BIOS from MSI’s official site

Think of it as a “staged release” – safer than pushing a single build to all boards at once.

User Reports & Issues (Important Section)

Reported Problems

While the update brings improvements, early adopters reported:

• Boot issues: system not completing POST or taking longer than usual
• BIOS access problems: some users could not enter the BIOS screen after flashing
• RAM/XMP instability: memory overclocking or XMP profiles not working as expected

Understanding “Early BIOS Build”

• An early BIOS build is the first version released for testing by users
• It may include critical fixes but could also introduce new issues
• Users are advised to wait for stable builds unless they need a specific fix or feature

In short, while the update is promising, careful adoption is key to avoid system instability.

How to Check MSI BIOS Version

Before updating your BIOS, it’s crucial to know which version is currently installed. Here are the easiest ways to check:

Method 1: BIOS Screen

1. Restart your PC.
2. Press the Delete (DEL) key during startup to enter the BIOS.
3. Look for BIOS Version or Firmware Version in the system information section.
4. Note the version number and release date.

This method is the most accurate because it directly reads the firmware installed on your motherboard.

Method 2: Windows System Information

1. Press Windows + R, type msinfo32, and press Enter.
2. In the System Summary, look for BIOS Version/Date.

Quick and easy method without restarting your PC.

Method 3: Command Prompt (Advanced Users)

1. Open Command Prompt as Administrator.
2. Run the command:

wmic bios get smbiosbiosversion

3. Your current BIOS version will be displayed.

Important Tip:
Always verify your current BIOS version before updating. Flashing the wrong BIOS version can brick your motherboard.

Should You Update MSI BIOS Right Now?

Deciding whether to update depends on your system needs:

Yes, Update If:

• You are installing a new CPU or RAM that requires updated firmware.
• You need a specific bug fix or stability improvement included in the latest BIOS.

No, Don’t Update If:

• Your system is already stable and working fine.
• You are using your PC for daily work or production, where downtime could be risky.

The general rule: update only when necessary, not just because a new version exists.

How to Check Latest MSI BIOS Version

Before flashing, it’s important to know the latest official version for your motherboard:

1. Identify your exact motherboard model.
2. Visit the MSI official support website: https://www.msi.com/support
3. Search your model and go to the BIOS section.
4. Compare your current BIOS version with the latest available and read the changelog for fixes and new features.

How to Update MSI BIOS Safely (Quick Steps)

Step 1: Prepare a USB Drive
