Question How do I update the BIOS on this Asus motherboard without a CPU ?

[GBDev]

Hello,

So i own a an Asus TUF B760M-PLUS WiFi motherboard and an i7-14700KF CPU.
The CPU is compatible with the motherboard but only after it’s updated to at least version 1205 of the BIOS. So my question is:

If the CPU is not compatible just yet, How do i update the bios version? There is no USB port labeled with BIOS or any indicator so I cannot do a BIOS flash without the CPU i assume. And I’m told that if I install my CPU i probably won’t be able to boot into the BIOS to update it. So i’m lost, What am I able to do to update the BIOS so i’m able to use my CPU

Simple answer; You don't. You will need a prior generation processor in order to flash the BIOS to the latest version then clear the CMOS, then drop in the latter processor onto the socket. Had the board had a BIOS FlashBack button, you wouldn't have needed to go through the aforementioned steps.

Why are you dropping an unlocked processor onto a chipset/board that won't allow you to take advantage of the processor? You should be looking at a Z790 chipset to pair with that i7-14700KF. On that note, if I were you, I'd look into the K SKU instead of the KF SKU since the iGPU will come in handy when you need to diagnose display related issues.

Okay, So i should replace my 14700KF with a 14700K?

does that also solve my main issue of being able to upgrade the BIOS?

They are same except F has IGPU disabled. That doesn't matter since you wouldn't be able to see BIOS anyway. What you need is any CPU compatible with 0264 BIOS version. Even Pentium or Celeron,

The only answer is this:

You need to drop in an older CPU (12th-gen should be safe) that the motherboard recognises in order to update the BIOS to the point that the mobo recognises 14th-gen.

There is no way around it, period. As things currently are, your CPU is a piece of sand and your motherboard is a brick.

Try it.
Bios 1205 with 14th gen support was released June 2023.
A motherboard made after then would include the latest bios.

If you bought old stock, see if you can't get a fresh motherboard.
Or, pay a shop to do the flash for you using a compatible processor.

You saved some $25 or so by getting the F version.
Sooner or later, you will want integrated graphics. If the exchange is easy, I would consider it.
F or K has nothing to do with bios level.

Ah okay, I guess I'll just pay my local computer store to upgrade it for me

I have switched out to the K version and yeah i'll pay the shop to do it

thank you all for your support!

The CPU will still work in the board, you just wont be able to use any of the PCI lanes that are controlled by the CPU.

So normally the top M.2 socket and top PCI-e slot for a GPU. If you have to have a GPU for video, install it in a lower slot and boot up to the BIOS and install the most current BIOS. Once done you will be able to move the GPU up to the #1 PCI-e slot and install a M.2 in the top socket.

Ive run into this issue with 2 Asus Prime z790 boards and 14700k's

I just flashed the Bios on my Motherboard before putting CPU or RAM in it ...... uses QFlash function - does your board manufacturer have a similar function ? that ?

The only ASUS boards with such a feature have a USB BIOS FlashBack button on the rear I/O cluster to trigger it. The OP's board does not have that so will require a CPU and RAM. Sometimes though even an incompatible CPU will run well enough to flash a BIOS, plus the earliest compatible BIOS is so old that one may already be installed--hence the suggestions to just try it and see if it POSTs. If it does but there is no video, then the suggestion of using an old GPU in one of the chipset-controlled slots sounds reasonable.

Thanks for best answer! I'm sorry that I didn't have good news for you, but I always say that it's better to tell the truth.

This is really confusing. I want to buy a ASUS - TUF GAMING Z790-PLUS WIFI (Socket LGA 1700) Intel Z790 ATX DDR5 Wi-Fi 6E Motherboard.

As per asus website : https://www.asus.com/us/motherboard...esk_bios?model2Name=TUF-GAMING-Z790-PLUS-WIFI
The most recent BIOS is version 1805 : 2024/11/04.

However, partpicker states:
Warning: The Asus TUF GAMING Z790-PLUS WIFI ATX LGA1700 Motherboard supports the Intel Core i5-14600K 3.5 GHz 14-Core Processor with BIOS version 1205. If the motherboard is using an older BIOS version, updating the BIOS will be necessary to support the CPU.

Could some intelligent person tell me what to do?

You are good most likely.

Motherboards will have the most current bios level when made.
The 1205 level was released in June of 2023.
Unless you are getting very old stock, you are good.
