Should I update bios?

mdaw · 13 Oct 2025 at 12:29

After much faffing around today, (I'm not software savvy but can build a PC) I've finally managed to get my computer to boot in uefi and enabled tpm 2.0 on my MSI X570 tomahawk wifi. All I needed to do was change my OS drive to GPT but isn't as simple as just changing it in disk management but through command prompt. reason is to move to windows 11. I've managed to do this all on the original bios. (I thought I'd need to update it to do the above).
Before moving to windows 11 do you think I should update it or just leave it? I've never had any problems and the old adage, don't fix it if it ain't broke, seems to have been common in the past when updating the BIOS. Which makes me a bit insecure about doing this.

Bios updates will include newer Agesa versions and if you might be changing your CPU at a later date will need a newer bios that supports it.

I wouldn’t personally unless I was experiencing a problem that a BIOS update was likely to resolve. As you said, if it ain't broke…

So basically don't bother unless I'm upgrading the CPU. I have thought about an x3d upgrade at some point. Not sure how much longer the 5700x3d is going to be on sale for.

I wouldn't update unless there is a security vulnerability that needs to be addressed or it adds a feature that you need (e.g. new cpu support)

Never had any issues with bios flashing and I've done a lot.

I have a board from the same family from MSI, and one of the latest BIOS release for mine fixed the sinkclose vulnerability, and an issue with the TPM and running some newer games, so more useful than just the usual microcode updates.

I used to always update my bios on all boards but stopped doing it unless there was something wrong.

Check if Bitlocker is and turn it off before as updating BIOS can wipe the keys

If it ain't broke, don't fix it! You only need to do it if you are having issues, or you are going to update your hardware.

BIOS updates fixes security holes, improves memory support, fixes any possible vcore overvoltage and can improve performance

Very true, but every time I've had an issue and hoped a BIOS update had fixed it, it did not. Just my bad luck

They can also introduce those issues - which is how those issues would have been included in the first place.

Update your bios when and if the board is a new to market model (so more likely to have issues previously undiscovered) or you're trying to resolve a specific issue otherwise leave well enough alone.

Always update, especially if installing a new OS.
