Crosshair VI X370 Zen 3/Ryzen 4000 support

[Firedrops]

So we've all seen the news, AMD does not REQUIRE vendors to support 4000 on older boards.

But in practice, the 3000 series and older boards, and older CPUs with newer boards saw pretty good compatibility from the vendors.

CH6 has 16MB rom, current bios uses 10MB.

Will Asus provide Zen 3 support?

I had high hopes for the X370 chipset being supported. It seems like that was hinted (if not outright stated) that the X370 would be able to handle the next gen ZEN.
Seeing that EKWB now has full cover MB and chipset blocks for the X570 boards then I'm ready for to move up to the 4000 series. I hope it doesn't suck...

There is at least one X570 board that I know of which only has an 16Mb BIOS chip.
It will be interesting to see if they manage to cram Zen 2 and 3 CPU support in without branching.

As of a few minutes ago, AMD just backtracked and will be providing beta AGESA support for 400 series mobos. Actual bios development will be up to vendors and the upgrade will be one-way with AMD verifying that you already have a Zen 3 processor ON HAND before allowing you to download the new bios. Thew new bios will NOT support older (zen 1-zen2) processors.

Seeing that Zen 1 and Zen 1+ were so technically similar, and that the new bios will already be segmented, it's kind of a bummer that the support was only given to 400 series.

With BIOS flashback support, it's strange that they would be all that worried about it. Make the new BIOS version available for flashback only, and that will limit it to those who actually know what they are doing, and probably with the ability to switch back if things go wrong.

The flash for the Ryzen 4000 series requires low level format of the bios which I think is why they are saying it is a one way trip for 400 series boards. Although x470 has same rom as x570 so maybe it will be able to be normal flash.

So it appears AMD is going to support the 400 series motherboards but not 300. That sucks. There's no reason they can't support 300 series boards. I was going to get a Zen 3 CPU but I guess now I won't be. My Crosshair VI Extreme has a 128mb BIOS I think.
