Updating the BIOS (Basic Input/Output System) on your MSI motherboard is far more than just a routine chore. Instead, it’s a critical maintenance task that acts like a finely tuned software update for your car’s engine, often providing vital performance enhancements, bolstering security, and ensuring compatibility with the latest hardware. Consequently, neglecting this crucial step can leave your system vulnerable, unstable, or unable to support exciting new components.
Indeed, think of your BIOS as the bedrock of your PC’s operations. Specifically, it’s the first piece of software that runs when you power on, initiating all your hardware before the operating system even begins to load. Consequently, an outdated BIOS can lead to frustrating compatibility issues with new CPUs or RAM, performance bottlenecks, or even expose your system to security vulnerabilities. Fortunately, however, MSI offers straightforward, reliable methods to update BIOS in MSI motherboard, empowering you to keep your system robust and future-proof.
Therefore, in this guide, we’ll dive deep into the two most recommended and reliable methods: the intuitive M-Flash utility accessible directly from your BIOS, and the powerful Flash BIOS Button, which can even revive a non-booting system. Furthermore, we’ll also touch upon a less-recommended software approach and equip you with crucial troubleshooting tips. Let’s ensure your MSI motherboard is running at its absolute best!
Why Updating Your MSI Motherboard’s BIOS Matters
First, before we delve into the “how,” let’s solidify the “why.” Indeed, you might wonder if you truly need to update BIOS in MSI motherboard. However, the truth is, while not always necessary for a functional system, timely updates offer a multitude of benefits. For instance, a new BIOS version might unlock crucial support for the latest generation of processors, thereby ensuring your system recognizes and fully utilizes that brand-new CPU you just bought.
Furthermore, these updates often address critical bugs that could be causing system instability, random crashes, or unexpected behavior. In addition, security vulnerabilities are also frequently patched through BIOS revisions, thus safeguarding your system from potential exploits. Beyond this, a fresh BIOS can sometimes enhance overall system performance, improve memory compatibility (think XMP profiles for faster RAM), or even add support for new storage technologies. Therefore, ultimately, staying current can significantly extend your motherboard’s lifespan and utility.
Method 1: Update BIOS in MSI Motherboard Using M-Flash (The Go-To Method)
M-Flash is MSI’s built-in, user-friendly utility designed to update BIOS in MSI motherboard directly from the BIOS interface itself. Indeed, it’s the most common and recommended method if your system can boot normally into the operating system or BIOS. Consequently, this approach provides a stable and controlled environment, minimizing risks.
Preparing for Your M-Flash Update
First, successful preparation is the cornerstone of a smooth BIOS update. Otherwise, skipping any of these steps could lead to frustrating errors or, in worst-case scenarios, a “bricked” motherboard. Therefore, always proceed with diligence.
Step 1: Identify Your Motherboard Model
First, you need to know your exact MSI motherboard model. Specifically, this information is usually printed clearly on the motherboard itself, often near the RAM slots, CPU socket, or the main 24-pin power connector. Therefore, look for specific identifiers, such as “MSI MAG B550 TOMAHAWK” or “MSI MPG Z790 CARBON WIFI.” Crucially, remember that even minor variations like “WIFI” or “non-WIFI” versions require different BIOS files.
Step 2: Download the Correct BIOS File
Next, visit the official MSI website (www.msi.com). Then, navigate to the “Support” section and use the search bar to find your specific motherboard model. Subsequently, once on its product page, select “Support” and then “BIOS.” There, you’ll see a list of available BIOS versions. Always, however, download the latest non-beta version. Indeed, beta versions are experimental and may introduce instability. Finally, extract the downloaded zipped file; consequently, you’re looking for a file ending in `.CAP` or `.ROM`.

Step 3: Prepare Your USB Flash Drive
Next, you’ll need a USB flash drive. For best results, therefore, use a drive that is 32GB or smaller, and preferably a USB 2.0 model, since some older BIOS versions might have compatibility issues with newer, larger USB 3.0/3.1 drives. Subsequently, format this USB drive to FAT32.
- Warning: First, formatting will erase ALL data on the drive. Therefore, back up any important files before proceeding.
- Process: To do this, right-click the USB drive in File Explorer (Windows) or Finder (macOS), select “Format,” and choose “FAT32” as the file system.
- Copy the BIOS File: Next, after formatting, copy only the extracted `.CAP` or `.ROM` BIOS file to the root directory of the USB drive. Crucially, do not put it inside any folders.
Executing the M-Flash Update Process
Now, with your preparations complete, you’re ready to initiate the update. Indeed, this process typically takes only a few minutes, but uninterrupted power is absolutely essential.
Initiating the Flash
- Enter BIOS Setup: First, restart your computer. Then, as the MSI logo appears, repeatedly press the “Delete” key on your keyboard until you enter the BIOS setup utility.
- Access M-Flash: Next, once in the BIOS, whether in the user-friendly EZ Mode or the Advanced Mode, locate and select “M-Flash.” Often, this option is prominent. Subsequently, you’ll then be prompted to confirm a reboot into M-Flash mode. Therefore, select “Yes” or “Enter” to proceed.
- Select BIOS File: Finally, your system will reboot into a special M-Flash environment. Here, you’ll see a list of available drives. Then, select your USB drive, and choose the BIOS `.CAP` or `.ROM` file you copied earlier.
Performing the Flash Operation
- Start Update: First, confirm your selection to begin the update process. Immediately, a progress bar will appear, indicating the flashing operation.
* CRITICAL WARNING: Critically, during this stage, DO NOT turn off your computer, unplug the USB drive, or interrupt the power supply. Indeed, any interruption can corrupt the BIOS firmware, thereby rendering your motherboard unusable – a state commonly referred to as “bricking.”
* Patience is Key: Furthermore, patience is key: the update can take several minutes to complete. Therefore, let the system do its work without intervention.
Finalizing and Verifying
- Automatic Restart & Verification: First, once the update is finished, your system will automatically restart. Then, upon reboot, immediately re-enter the BIOS (by pressing “Delete” during startup). Ultimately, verify that the new BIOS version is displayed, thus confirming a successful update.
- Reconfigure Settings: Crucially, remember that a BIOS update typically resets all settings to their default values. Consequently, if you had custom configurations like X.M.P/A-XMP/E.X.P.O profiles for your RAM, fan curves, or boot order preferences, you will need to re-apply them.
Method 2: Update BIOS in MSI Motherboard Using the Flash BIOS Button (for Non-Booting Systems)
The Flash BIOS Button (often referred to as BIOS Flashback) is an incredible feature that allows you to update BIOS in MSI motherboard even when your system won’t boot, for example, when installing a new CPU that isn’t yet supported, or incredibly, even without a CPU, RAM, or graphics card installed. Therefore, this makes it an indispensable tool for troubleshooting or initial builds. However, not all MSI motherboards have this feature, so check your specific model’s rear I/O panel for the dedicated “Flash BIOS Button.”
Preparing for Your Flash BIOS Button Update
Specifically, this method has a slightly different preparation, especially regarding the BIOS file’s name.
- Download BIOS File: First, just as with M-Flash, download the correct, non-beta BIOS file for your exact MSI motherboard model from the official MSI website.
- Format USB Drive: Next, format a USB flash drive (preferably 32GB or smaller) to FAT32. Again, ensure you back up any data, as formatting will erase everything.
- Rename BIOS File: Crucially, this is a crucial step for the Flash BIOS Button: after extracting the downloaded BIOS file, you must rename it to “MSI.ROM.” However, while “MSI.ROM” is the most common filename, always consult your motherboard’s manual for the precise required name, since it can sometimes vary (e.g., “MSI.CAP”). Finally, copy this renamed “MSI.ROM” file to the root directory of your FAT32 formatted USB drive.
Executing the Flash BIOS Button Update Process
Furthermore, this process requires precision, especially regarding which USB port to use.
- Power Connection (No Boot): First, ensure your motherboard has power connected (both the 24-pin ATX power connector and the 8-pin/4-pin CPU power connector). However, the PC itself should be switched OFF. Importantly, you do not need the CPU, RAM, or GPU installed for this method to work.
- Insert USB Drive: Next, locate the dedicated “Flash BIOS Button” USB port on your motherboard’s rear I/O panel. Typically, it’s clearly labeled and positioned near the Flash BIOS Button itself. Then, insert your prepared USB drive into this specific port.
- Press Flash BIOS Button: Subsequently, press and hold the small, physical “Flash BIOS Button” for about 3-5 seconds.
- Monitor LED Indicator: Then, a dedicated LED light (often near the button or USB port) will begin to flash, thereby indicating that the BIOS update process has started.
* CRITICAL WARNING: Critically, just like with M-Flash, do not interrupt the power, remove the USB drive, or press any other buttons while the LED is flashing. Otherwise, interruption can lead to a bricked motherboard.
- Completion: Finally, the LED will stop flashing once the BIOS update is complete. At this point, the system may automatically restart or power off entirely. This, therefore, indicates a successful update.
- Post-Update: Afterward, if you performed this update with minimal components, now is the time to install your CPU, RAM, and GPU. Then, power on your system, enter the BIOS, and configure any settings (like XMP) as needed.
Method 3: Avoiding MSI Center / Dragon Center (Least Recommended)
While MSI does offer software suites like MSI Center or the older Dragon Center, which sometimes include a BIOS update utility, nevertheless, the consensus among experienced users and system builders is to avoid using them for BIOS updates. This is because these software-based updates run within your operating system, which is an inherently less stable environment compared to the bare-metal M-Flash utility or the dedicated Flash BIOS Button. Consequently, updates performed through the OS are more susceptible to interference from background applications, drivers, or system instability, thereby significantly increasing the risk of a failed update and potentially bricking your motherboard. Therefore, for maximum reliability and peace of mind, stick to M-Flash or the Flash BIOS Button.
Important Considerations for a Successful BIOS Update
Indeed, updating your BIOS is a delicate operation that demands attention to detail. Therefore, keep these critical considerations in mind to ensure a smooth, risk-free experience. Ultimately, these insights can save you from potential headaches and system downtime.
Stable Power Supply
First and foremost, this cannot be overstated: a stable and uninterrupted power supply is paramount. Specifically, a sudden power outage or fluctuation during a BIOS update can instantly corrupt the firmware, thus making your motherboard unbootable. Therefore, consider using an Uninterruptible Power Supply (UPS) for your PC, especially if you live in an area prone to power disruptions. Ultimately, it’s a small investment that offers huge peace of mind.
Correct BIOS Version
Always, without exception, download the BIOS file specifically designed for your exact motherboard model and revision. Indeed, installing an incorrect BIOS version is a guaranteed way to cause severe system instability or, or worse, render your motherboard unusable. Therefore, double-check your model number on the motherboard and verify it against the MSI support page. Crucially, don’t assume a similar model will work.
USB Drive Compatibility
As previously mentioned, using a reliable USB 2.0 drive, preferably 32GB or smaller, and formatted as FAT32, often yields the best results. This is because some newer, larger, or USB 3.0/3.1 drives can sometimes cause issues with older BIOS implementations. Furthermore, ensure the BIOS file is indeed in the root directory and not nested within any folders. For instance, a common mistake is to copy the entire zipped folder instead of just the extracted `.CAP` or `.ROM` file.
Post-Update Checks
After a successful update, make it a habit to immediately enter the BIOS (by repeatedly pressing “Delete” during startup) to confirm the new BIOS version. Indeed, this small step validates your update. Beyond that, moreover, remember that all your custom settings – XMP profiles for RAM, boot order preferences, fan speed curves, virtualization settings – will likely have reverted to default. Therefore, take the time to reconfigure them to your liking for optimal system performance and behavior.
Troubleshooting Common BIOS Update Issues
Even with the best preparation, unforeseen issues can sometimes arise. Therefore, knowing how to troubleshoot these problems can be a lifesaver.
Failed Flashing (LED Flashes Briefly/Not at All)
- Rename Check: First, double-check the BIOS file name. Specifically, for Flash BIOS Button, it MUST be `MSI.ROM` (or as specified in your manual).
- USB Port: Next, ensure the USB drive is in the dedicated Flash BIOS Button USB port.
- USB Drive: Alternatively, try a different USB drive. Often, older, smaller drives (e.g., 8GB USB 2.0) work best. Then, reformat to FAT32.
- Power: Furthermore, ensure all necessary power cables (24-pin ATX, CPU power) are securely connected.
- Re-Extract: Finally, re-download and re-extract the BIOS file to ensure it wasn’t corrupted during download.
System Instability After Update
- Clear CMOS: First, perform a CMOS clear (either by removing the motherboard battery for 5-10 minutes with the PC unplugged, or by using the dedicated CMOS clear jumper/button on your motherboard) to fully reset BIOS settings.
- Default Settings: Next, boot into BIOS and load “Optimized Defaults” or “Default Settings” to rule out any reconfigured settings causing conflict.
- Previous Version: Furthermore, if severe instability persists, consider downgrading to the previous stable BIOS version, which is often possible with the Flash BIOS Button method.
“No CPU or RAM Detected” After Flash BIOS Button
This, unfortunately, usually indicates the BIOS update failed to apply. Therefore, repeat the Flash BIOS Button process carefully. Additionally, ensure your CPU and RAM are compatible with the newly updated BIOS version. Finally, if you still cannot flash with a bare motherboard (only power and USB drive), there might be a hardware fault with the motherboard itself.
Is a BIOS Update Always Necessary?
First, it’s an important question to ask: “Do I really need to update my BIOS?” However, the simple answer is, not always. Specifically, if your system is running perfectly stable, supporting all your hardware, and you’re not experiencing any issues, there’s often no urgent need to update. Indeed, “If it ain’t broke, don’t fix it” holds some truth here, given the inherent, albeit small, risks.
However, you should strongly consider an update if:
- For example, you’re upgrading your CPU to a newer generation that requires a specific BIOS version for compatibility.
- Alternatively, you’re experiencing specific hardware compatibility issues (e.g., new RAM not running at XMP speeds, certain PCIe devices not detected).
- Moreover, you’re encountering persistent system instability or mysterious crashes that might be linked to known BIOS bugs.
- Finally, a critical security vulnerability has been identified and patched in a new BIOS release.
Crucially, remember to avoid beta BIOS versions unless absolutely necessary for specific hardware support, as they can be less stable.
