BIOS Updates: Are You Leaving PC Performance on the Table?

Yes, ignoring BIOS updates can leave performance on the table, especially on newer CPUs and platforms. Updating your motherboard’s BIOS/UEFI firmware can improve CPU stability, enable new features like Resizable BAR, fix memory compatibility issues, and sometimes deliver a few percent more performance in games and productivity apps. However, the gains vary widely by system, and a botched update can brick your motherboard, so it’s not something to do blindly.

What a BIOS Update Actually Changes

The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is low-level software stored on a chip on your motherboard. It initializes hardware during boot and provides a runtime interface for the operating system. Updates come from the motherboard manufacturer (ASUS, MSI, Gigabyte, ASRock, etc.) and typically include:

• CPU microcode updates – patches for security vulnerabilities (e.g., Spectre, Meltdown) and fixes for erratic behavior.
• Memory compatibility improvements – better support for higher-speed DDR4/DDR5 kits and stability at XMP/EXPO profiles.
• New feature enablement – such as Resizable BAR (Smart Access Memory) for AMD GPUs, or support for newer CPU generations on the same socket.
• Bug fixes – for issues like fan control glitches, USB dropouts, or sleep/wake problems.
• Performance optimizations – sometimes adjustments to power management or boosting behavior that can yield small FPS gains.

For example, AMD’s AGESA (AMD Generic Encapsulated Software Architecture) updates have historically improved Ryzen performance and stability, particularly for memory overclocking. Similarly, Intel’s microcode updates have fixed e-core scheduling issues on 12th/13th gen CPUs.

When Updates Matter Most

Not every system benefits equally. Here are the scenarios where updating is most likely to affect performance:

• New CPU or RAM – If you’ve upgraded to a newer processor or bought high-speed memory, a BIOS update may be required just to boot, let alone run at rated speeds.
• Early adoption – Motherboards shipped with early BIOS versions often have immature memory training and boosting algorithms. Later updates can tighten timings or improve boost clocks.
• Security patches – Some microcode updates can slightly reduce performance (e.g., the original Spectre mitigations), but later revisions often recover some of that loss.
• Resizable BAR – This feature can boost GPU performance in some games by allowing the CPU to access the full VRAM. It requires a BIOS update on many platforms.

Conversely, if your system is stable, runs all your software, and you’re not chasing every last frame, the performance difference may be negligible. In many cases, updates are more about stability and security than raw speed.

How to Check Your Current BIOS Version

Before updating, you need to know what you have. The easiest way is to use the built-in Windows System Information tool:

1. Press Win + R, type msinfo32, and press Enter.
2. Look for “BIOS Version/Date� in the System Summary. It will show something like “A.30� or “1.2.0� plus a date.
3. Note the exact string and the date.

Alternatively, you can restart and press the key shown on the splash screen (usually Del or F2) to enter the BIOS setup and read the version there. On Linux, you can run sudo dmidecode -t bios in a terminal.

How to Update Safely

Updating BIOS is safe if done correctly, but a power failure during the process can leave the motherboard unbootable. Follow these steps to minimize risk:

1. Identify your exact motherboard model – Check the board itself or use a tool like CPU-Z. Do not guess; wrong firmware can brick the board.
2. Download the BIOS file only from the manufacturer’s official support page – Avoid third-party sites that may host modified or corrupted files.
3. Read the release notes – They often mention if a previous update is required before applying the new one.
4. Use the built-in flash tool – Most modern boards have a “M-Flash� (MSI), “EZ Flash� (ASUS), “Q-Flash� (Gigabyte), or similar utility in the BIOS itself. This is safer than flashing from Windows.
5. Connect a UPS or ensure stable power – If you have frequent outages, consider waiting for a calm moment or using a laptop with a charged battery (if applicable).
6. Do not interrupt the process – Leave the PC alone until the tool says it’s done and reboots.

Many modern boards also support “BIOS Flashback� or “USB Flashback� – a feature that lets you flash the BIOS without a CPU or RAM installed. This is a great recovery option if a flash fails.

Common Problems and Misconceptions

“BIOS updates are risky and never worth it.� While there is a small risk, the vast majority of updates go smoothly. The bigger risk is not updating when a critical security patch or a compatibility fix is released.

“Newer BIOS always performs better.� Not necessarily. Occasionally a manufacturer introduces a regression (e.g., worse memory compatibility). If you notice a new problem after updating, you can usually downgrade to the previous version, though some boards restrict downgrades after certain updates.

“I need to update the BIOS to install a new CPU.� Often yes, but some boards support “USB BIOS Flashback� to update without a CPU. Check your motherboard manual for the specific procedure.

“BIOS updates are like driver updates – I should install every one.â€� Unlike drivers, BIOS updates are less frequent and more impactful. It’s fine to skip minor ones if you’re not experiencing issues, but you should install updates that address security vulnerabilities or add features you need.

How to Decide If You Should Update

Here’s a practical checklist:

• Are you experiencing stability issues (crashes, random reboots, memory errors)? → Update.
• Are you using a new CPU or RAM that isn’t fully supported? → Update.
• Is there a known security vulnerability affecting your platform? → Update.
• Do you want to enable Resizable BAR or other new features? → Update.
• Are you happy with current performance and stability? → You can wait, but check release notes periodically.

If you’re a competitive gamer or a content creator who needs maximum performance, it’s worth checking the release notes for “improved performanceâ€� or “optimized boostâ€� mentions. For general users, the performance gains are usually small (1–3% at most), but the stability and security benefits are more significant.

Alternatives to Updating

If you’re hesitant to update, there are a few alternatives to squeeze out performance:

• Enable XMP/EXPO – This runs your RAM at its rated speed, which can improve performance more than a BIOS update in many cases.
• Update chipset drivers – These are separate from BIOS and can fix power management and PCIe issues.
• Update GPU drivers – Often more impactful for gaming performance than BIOS updates.
• Adjust power settings – Ensure Windows is set to “High Performanceâ€� or “Ultimate Performanceâ€� and check your motherboard’s power profile.

These won’t replace a BIOS update when one is needed, but they can improve performance without touching firmware.

Frequently Asked Questions

Will updating BIOS improve my FPS in games?

Sometimes, yes, but usually by a small amount (a few percent). The biggest gains come from enabling Resizable BAR and fixing memory compatibility so your RAM runs at its rated speed. If your system is already stable and running at full boost clocks, don’t expect a dramatic jump.

Can a BIOS update damage my PC?

Yes, if the power goes out during the flash, the motherboard can become unbootable. However, most modern boards have dual BIOS or USB flashback recovery features. The risk is low if you follow the manufacturer’s instructions and use a stable power source.

How long does a BIOS update take?

Typically 2–5 minutes. The screen may flicker or go black, and the PC may restart automatically. Do not turn off the power during this time.

Do I need to update BIOS for a new CPU?

Often yes. If you’re installing a newer CPU on an older board, the board may not recognize it without a BIOS update. Check the motherboard’s CPU support list and the required BIOS version.

Should I update BIOS if my PC is working fine?

Not necessarily. If you’re not experiencing issues and there are no security patches you need, you can skip it. But it’s wise to check the release notes occasionally, especially if you plan to upgrade hardware later.

What is the difference between BIOS and UEFI?

UEFI is the modern replacement for the traditional BIOS. It offers a graphical interface, faster boot times, support for large drives, and a secure boot feature. Most motherboards today use UEFI, but the term “BIOS� is still commonly used. Updating either is the same process.
