MSI confirms its AMD 400-series motherboards support Zen 3

[HEXUS]

Boards with the smaller EEPROMs may have to use a compact 'selective beta BIOS' update.

Good to hear!!

I have a MSI X470 Gaming Plus (Non-MAX) board with a 16Mb BIOS.

I thinking that MSI may have to drop support for older Ryzen 1000 & 2000 series CPUs to accommodate the new ZEN 3s, if they commit to pushing out a new BIOS for that specific model. Otherwise I may have to look elsewhere for a new motherboard.

I think you'll be fine.
There are several X570 mobos which come with 16MB large ROM chips... and it was mentioned that ALL X570 and B550 mobo's will support Zen 3.

Something was mentioned that for older mobos like B450/X370, support for entire Zen 1 series and Zen+ APU's would be removed to make room for Zen 3.

I'm on Acer Predator helios 500 PH517-61 laptop which is a desktop replacement with desktop Ryzen 2700 and Vega56.
Its quiet and cool at maxed out load (cooler and quieter than any other laptop on the market)... and despite the fact I have a B450 desktop grade motherboard in the laptop, Acer stopped supporting the unit in about late 2018 or very early 2019.

It wouldn't be a big deal for Acer to release a BIOS update for this laptop so I can slap in Zen 3 and 3200MhZ RAM, but they are too lazy.

Oh and I forgot to mention that the ROM chip in my B450 mobo is also 16MB in size.
So yes, it could easily house Zen 2 and Zen 3 support if entire Zen 1 line and Zen+ APU's are removed (since this laptop never came with a Zen+ APU and the display is not connected to the socket, it wouldn't be able to make use of an iGP anyway - which is sad I suppose as Zen 3 65W TDP APU would be amazing for this machine in regards to performance increase and battery life).

Vega 56 is still more than enough to max out games on this thing and I can easily overclock and undervolt it to match GTX 1080 without exceeding its 120W locked TDP.

To late for my b450 gaming pro max - I hadn't opened the box when AMD originally announced so returned it for an ASUS tuf gaming x570-plus. I had been torn between a x570 for future upgrades and saving money on a b450 board. I do intend to keep this machine for a good 5 to 8 years so being able to go PCIe 4 and push a 4800x or equivalent in a few years is essential to me.

4950XT surely?

This is amazing. I'm very happy with my MSI B450I and they seem to have the best support compared with the other mainstream manufacturers.

Hope ASRock give us an update soon, I got the B450M due to the additional cost for a 500 series board not being worth it, I was expecting the B450M to be the last of the AM4 before they went AM4+ and having a whole new (600 maybe) chipset..

I wish... Got to replace the rx480 first and that's going to have to wait a year having just spent out £600 on the new system. I think going 8 core will be pretty essential in 5 years time.
