AMD B550 Chipset Detailed, It's Ready for Zen 3, Older AM4 Motherboards not Compatible

I wouldn't be surprised if board vendors give X470/B450 support for 4th gen Ryzen.

And miss the opportunity to sell new boards? Dunno.
This official "not supported" from AMD is the perfect scapegoat.
 
too small ROM, hahahaha
It is very difficult, to prepare ROM with limited / removed support for Ryzen 1000 / 2000 just to make space for Ryzen 4000.

These boards being mainstream, probably don't pack 256Mbit ROMs :(
 
just set up my refund for my b450 tomahawk max, will be going z490 and intel 10 core, and ampere. fk it
 
I can understand leaving out the 1st and 2nd gen Ryzen CPU support. Leaving out 3200g and 3400g support is just stupid. Either they don't care about APU's anymore, or there are some new ones coming soon, that we are just not aware of.

You do realize 3200G and 3400G ARE 2nd generation Ryzens, don't you?
 
Just go for a 3800X/3900X and a X570 and call it a day. Hell, go for 3950X if you got the budget. Amazon US has it for $720 at the moment and I'm trying not to be tempted.

nah, Z490 is almost here. might as well go with that will get the $169 MSI Z490 board and the $499 Intel 10 core, and hopefully rtx 3080 will be out before cyberpunk 2077 comes out. i really enjoy overlcocking gpu and navi was never able to deliver on that stable, i won't be overclocking cpu so ryzen is still decent, but i might as well go with z490 now that its here. it will be faster in most games i expect, 9900k still beats amd by 5-10 fps across the board. i expect it will be around same here if not a little more.
 
Mobo manufacturer can bypass this, you can see A320 boards supporting Ryzen 3000 series no problem at all.

Yes, but they do it by dropping some features. Whether that affects you or not will vary, official support would have been nicer.
Personally I'm not fretting over this, but supporting several generations with the same chipset was one of Ryzen's selling points, I can see how some are getting a dose of reality check now.
 
Is the slide showing out of box compatibility?? X370/B350 boards defenetly support Mattise cpus with updated UEFI, but the slide only showing it supports X470/B450.

The issue is supporting Zen3 on x3xx or x4xx boards will mean a lot of compromise & workarounds for AMD, board partners & consumers. Then when something doesn't work or a (low quality?) board craps out the user will bring his tiki torch for the MB vendors &/or AMD, this is definitely unexpected though the move to PCIe 4.0 & 16 core necessitated it!

The slide shows what AMD mandates. Support for anything else is up to the manufacturer.

Yes, but there is no justifiable reason not to include them, as they are a starter CPU, for many. I can understand leaving the 2nd gen CPU's out, but these APU's should be included.

Which is why I didn't give Intel any grief over changing sockets. But there are those that disagree with my view ;)

I don't think you understand how this works. Support is added for the entire architecture, not on a per SKU basis.
 
first gen ryzen couldn't keep ram stable for it's life. so not really, 2 generations if we talking stable performance.
Don't be silly I've ran several mismatched kits on ryzen 1 and b350 since the very first bios which are nowhere near as refined as today's and had no problems, and even overclocked them, yes people had issues though you can't make out like it was the whole platform, it wasn't, and it has been 3 generations, some people are still rocking x370/b350 boards with ryzen 2

They're zen+ not zen2 though

Most of the MSI "MAX" boards have 256Mb (32MB), we shall see...
From my opinion I would gladly trade the GUI bullcrap (hate it btw), StoreMI and even raid support for Zen2 support.

If budget is of your concern, the 12-core 3900X is also at $432, which is good deal. I use a 2080 Super in mine and I don't have any problems. I would only go Intel if I absolutely need high FPS and even then thats only for competition.
 
Intel did this every gen, even when it wasn't needed. They're not at all comparable in the least.
ASUS is on record saying Z370 boards didn't need to exist, for 8700k, yet Intel forced the change. False equivalence there :shadedshu:
Let's not go there again. All I said was I wasn't bothered then and I'm not bothered now.

You also need to check the slide carefully , casuse there is a footmark with this line -> *Planned feature support,Subject to change.
And there is nowhere says AMD mandates it.
 
Wooooooo so it was a good idea to invest in a X570 board early on. :love:
Yeah, same thought here. Bah, I had to buy a motherboard anyway (coming from Intel), so it wasn't like I was investing in something that I could potentially not need.

I'm not sure that ROM size limits are the true reason why AMD won't support 300 and 400 chipsets for Zen 3, but I don't know how much space is needed to support each Ryzen gen. And thinking about it, if Zen 3 really needs a lot of space, it would be a nightmare to have a BIOS version to support Zen & Zen 3 (for upgrading from a Ryzen 1700 on a X470 board to a Ryzen 4700X, for example), another to support Zen+ & Zen3, and another one to support Zen2 and Zen3. And we still haven't taken into account the UI that mobo makers add for the BIOS and some other stuff, I guess.

That aside, how much more expensive would it be for a consumer if motherboard makers used 256 Mbit ROMs? I think someone said it was like just an extra dollar per board to switch from 128 to 256Mbit per ROM chip...

I don't know specifics, but when Zen2 support was added to (some?) 128Mbit boards, features were lost in the process. Non-essential features, of course, but it's never nice to lose something you paid for.
