X370=x470 !?

1 : Anonymous2021/11/19 14:23 ID: qxh9db

I just flashd a x470 BIOS on my x370 Board and it works!

but why and how?

Spme models are very similar if not same with different name and maybe visual changes.

Which board exactly?

I was looking to try X470 Prime Pro BIOS on X370 Prime Pro.

I think I read it won't work but that's just a foggy memory. If you can do it for science we'd be quite a few interested.

X370 and X470 are identical both electrically and feature-wise, they only differ in name.

In some cases AIB's will use a modular BIOS that supports common components like the LAN controller, USB controller and VRM's across multiple boards. But there are also cases where AIB's released an X470 board with entirely identical components to their X370 board, and only made improvements like better DRAM signal isolation for higher DRAM clock speeds and better DDR4 compatibility on the X470 board.

In either case the X470 BIOS would work fine on the X370 board.

Also, if you're using an X470 BIOS with a recent AGESA version, you will now be able to run Ryzen 5000 series CPU, and you've just given planned obsolescence and unnecessary e-waste a giant middle finger, so grats on that. 😀

Do you think it's possible to flash the X470 Strix F BIOS to the X370 Strix F? From a visual standpoint there's a number of areas on the board with identical components and layouts, but other areas have things moved around a little. My worry is that there's no dual BIOS chips, so if I brick it the board is toast...

The X370-F has a 128mb flash rom (16MB), while the X470-F has a 256mb flash rom (32MB).

So, no, I don't think it would work.

I'd love to know this too. X370-F is a great board and would handle a 5950X with ease. So er whoever is feeling brave enough, be a hero...

He won't be able to. AMD blocks zen3, zen3&2 APUs past Agesa 1.1.x So he needs that specific version.

That's the first I've heard of this, and if that's the case, that's kind of a big deal.

Because that would mean AMD is requiring AIB's to go out of their way to make sure their X470 BIOS's that can be crossflashed to their X370 boards would be able to identify a crossflashed X370 board and prevent them from booting a Zen3 CPU.

Can you elaborate any more on this? I'd like to know a lot more....

I know this isn't the case with my MSI B450-A Pro. The latest BIOS is using C which dates from October 12, 2021.

I am running an R5 1600 at 3.4 GHz.

This almost true, x470 is a node refresh of x370... but yes identical other than using a little less power.

ID: hlagw58

This is not true. A crosshair 6 and 7 use different topography for the memory.

ID: hlbffvf

What differences does an x570 have compared to those two then? Better power phasing?

Just out of curiosity.

What happens if the update/flash fails? Would it be bricked? I assume not

ID: hl9tv61

It can brick but some motherboards have safety precautions that reload the original bios version in the event of a failure.

ID: hl9zkkr

will Q flash+ help in those cases

Same mb just different name. Same shit like hd6950-6970 you coudl flash the same bios on both card

Sounds like you got lucky. That's a damned good way to brick a board.

7 : Anonymous2021/11/19 19:27 ID: hlak2em

inb4 we starting seeing posts of bricked motherboards on tech subreddits

I've had some weird bios stuff too. My 3700x worked find on a B350 board and my R5 1600 worked fine on my X570 Prime. Even though neither of these combos officially work, I had no trouble with them.

Bro, you are very lucky!

but why and how?

Ryzen AFAIK has shifted to what's called a SoC design. SoC means System on Chip. That means that basically what they do, is they take an entire computer, everything the computer needs to function, and they put it on one chip, the CPU.

Apparently there's also something called a "promontory" mode where the chipset, the x370, or x470, or x570, or b550 doesn't function at all.

You must have an Asus x370.

same hardware
