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?

[Legate]

I doubt it very much.

Continuing to offer Backwards compatibility does not sell new motherboards unfortunately.
Probably means I will give the 4xxx series an miss.

New modding scene incoming .... my2cents

I doubt that we'll see it. AMD doesn't really want the vendors to support it as it's creating too much confusion as to what's supported and what's not when you start marrying different chipsets to the same processor. It's great for the enthusiast community who upgrades individual components periodically to keep up with the times but your average consumer upgrades everything holistically at the same time and that's what they're catering to. This is why Intel has always been bad about backwards compatibility as they want a clean upgrade path where you use this processor, you get these features. End of story. I think AMD is starting to realize there is a middle ground to be had but supporting things across what will be 4 chipsets when that series launches is going to be very difficult and stressful for retailers and consumers with varying support for features.

The below seems more likely the reasons

'According to AMD, this is due to the flash memory chips’ limitations that does not have enough space to support a newer set of codes. The current 400-series chipsets already have support for every Ryzen generation so far, so perhaps AMD has stretched compatibility to its maximum.'

"The AM4 socket and B450 chipset are confirmed to be able to support future AMD Ryzen 4000 Desktop CPUs," the rep wrote.

Which means a New modding scene is incoming if the manufactures drop the ball. Just as happened when Intel dropped RAID support on older chipsets saying it would not fit newer raid bios, yet still people found a way.

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.

At this point, AMD will be switching sockets to AM5, probably next year. If Asus provides support for first gen motherboard owners to the new generation, then those who are skipping Zen3(desktop Ryzen 4000 CPU series) will be more inclined to go with the next ROG Crosshair motherboard in their next build. I did the jump from the 1800X to the 3900X on my Crosshair VI Hero, and I've been encouraging customers to go with the Crosshair VII and VIII Hero boards for their new builds due to how happy I have been.

So, make ME happy, and that will result in dozens of additional motherboard sales, and in 2021 or 2022, chances are that I'd be going with a new motherboard with the new CPU. I may not be the source of hundreds of sales, but I personally have done at least 20 custom Ryzen builds over the past three years using this series of motherboards.

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.
