r/gamingportugal on Reddit: Update AM5 bios
February 25, 2025 -

Good morning,

I bought an MSI PRO B650M-b (without a flashback button) to build with a Ryzen 9 6000X. In my innocence, I thought it would be plug and play, but it seems I need to update the BIOS... Do you know any store/person in the south bank of Lisbon that does this service?

The CPU hasn't arrived yet, but I'm almost sure I need to update the BIOS, from what I've seen online.

Thank you!

UPDATE: It already came with the updated BIOS and recognized the CPU immediately

I have newly bought Gigabyte B650 GAMING X AX ATX AM5 Motherboard and 7800x3D still in boxes
I am waiting for the F6 bios to be released before I start building my system.
When F6 bios comes out, can I update it without inserting the CPU into the motherboard? I aint having that thing explode on me.
Also I wonder how long until F6 actually comes out, I hope its no more than a week? Considering all these voltages discoveries
There is currently F6 but its in beta version still, I dont wanna risk it with a beta version. Or at least waiting for a may beta version

What happens if BIOS does not support the CPU?

Then that means the user will have to update the BIOS to a firmware that does support that particular CPU. You can take 12th Gen Intel Motherboards, for example. It supports all of the 12th Gen and 13th Gen CPUs. But you will need a BIOS update to use any 13th Gen CPU on 12th Gen motherboards.

r/Amd on Reddit: AMD makes USB BIOS Flashback a universal feature with AM5, old cpu no longer required to flash bios
September 26, 2022 -

From Anandtech Review:

For the AM5 platform, AMD is taking matters into their own hands to make USB BIOS Flashback a universal feature. Ryzen 7000 chips will be able to support USB BIOS Flashback mode across the board and regardless of the BIOS currently installed. As a result, users will always be able to flash an updated BIOS to their AM5 boards, regardless of the CPUs supported by or the operational status of the current motherboard.

I have actually never updated a bios before and I saw that after the burned cpu's issue there was a bios patch release to prevent that from happening. I'm just going to assume if I buy a board it will need the bios updated, the question I have is, do I do that bios upgrade before installing the cpu? Or do you install the cpu and then run the bios update?

Hey everybody I got Gigabyte B650 gaming X AX V2 motherboard and a ryzen 7 9700x.

I’m building my pc tonight, and wondering how to go about getting the right bios. I’m pretty confident I’ll need to update the bios of the motherboard but how do I do that? I understand how to download it onto a flash drive, but how will I then update it without a CPU? Will it work without? And when should I do it in the build? I would prefer to do all the building at once, and then start sticking flash drives and what not in, but if the first thing I should do is unbox the power supply and motherboard and connect those two and then stick a flash drive in and it’ll update itself I’ll do that. And if I do that do I need to put RAM in?

tldr; how to update motherboard bios when the current bios doesn’t support the CPU I’m putting in.

r/ASUS on Reddit: [Help] How to update BIOS without supported processor?
November 3, 2025 -

I've brought Pro WS W680-ACE that supports 14th gen processor with BIOS update so I also brought 14700. It has BIOS Flashback so I thought I can do it without a 12th or 13th gen processor.

But when I went to download the latest BIOS it's showing that

Before BIOS update, please download the Intel ME update tool from the ASUS support site and update the ME firmware to Version 16.1.35.2557. to ensure optimized system settings.

How can I update the ME firmware before hand? I don't have 12 or 13 gen spare processor :(

SOLVED:

The motherboard was already updated to a newer (not latest) version that supported 14th gen CPUs

March 11, 2023 - It will probably bypass the cpu ... Click to expand... And run in the cloud? ... Click to expand... Only if its cumulonimbus. ... Click to expand... no ... Click to expand... Yup Looking at a couple of motherboards and they have the ability to flash from a specific USB slot, my guess is it's similar to the days of floppy disc bios recovery discs, there is probably a very basic processor in the motherboard chipset that takes the input from the "Bios flash" button as an interrupt and immediately looks for a bios file on the special USB port.

[SOLVED] - New am5 mobo will not boot usb or bios update | Tom's Hardware Forum
December 20, 2022 - If it is actually just a b650 Aorus Pro AX, then that board has Qflash Plus which means you can flash the BIOS without the system even running or even having a CPU, memory or graphics card installed. I would update your BIOS using the Qflash Plus method and see if this solves your problem.
