AMD not supporting Zen3 on older motherboards :(

Oh I got kind of confused for a second, because you title and post both mention Zen2 not being supported on 300 and 400 series boards

Actually the content does say AMD's official stance on 300 series compatibility with Zen2 is non existent, it's AIB choices that allow support of third gen on 300 series chipsets.

What a shame.

Well first Zen3 products actually have to release for sale in 2020 before crying can even start. Then there is the whole until issue, it's 2020. Does until have to mean till the end of? The start of? The middle of?

January first release date pencilled in then

[Morgan MLGman]

Well, according to AMD's latest slide my configuration also isn't "supported":


And yet I'm happily running a 3700X on an X370 board with 3600MHz memory.

I bought a B450 Gaming pro Carbon ac @ £120, pretty decent motherboard with excellent VRM reviews so assumed id get at least 1 upgrade cycle out of it and with all the hype around Zen3 assumed itd get to the point where AMD hands down had intel at the top end, paired with a next gen GPU and an Index headset i thought i had a decent plan but

B350/X370 = Zen (1800X)

B450/X470 = Zen1 (2700X)

X570 = Zen2 (3950X)

 

You have a board that can support a upgrade cycle just not two?

So can manufactures allow zen 3 on b450 ?

If they update bios. it is up to to the board manufacture pretty much. But based on the info the Zen 3 wont be able to run with b450 boards...

not when i bought it due to lack of options, i get what youre saying, from day of release but when 3000 series dropped you either shelled out big boy money for X570 or went for a decent B450 board and MSI with thier flashback function probable earnt megabucks off the back of that, all seems a bit for nought right now

From the video, there was explicit information from AMD that said no, it won't be possible, but they also said PCIe 4.0 was not possible on X470 and B450 but as we have seen, board partners have their own ideas about that. Boards like the MAX series from MSI and some higher end products from various partners have quite large BIOS chips that can accommodate more CPUs, and we have had internal leaks from some partners that B450 boards are slated to work with 4th gen parts, so at this time it's pretty uncertain, but it's not completely off the table.

With the launch of the 3300X and 3100, AMD has also released CPUs for all of AM4 in 2020, thus eliminating even complaints about Jan 1st or Dec 31st discussions.

This is where hardware unboxed clarification comes in that they specifically asked about AMD supporting the older chipsets with the AGESA bios code, and they replied very much negatively

I did similar, I went B450 board, got my 1700 for $136 shipped to be a placeholder, I fully expected to upgrade to 3000 series but got a golden sample OC so no need.  

 

Maybe Im in the wrong here but I wasn't expecting to support 4000 series chips in this socket, just 3000 series (maybe I had my dates wrong but this all seems good to me)

AM3? Good lord that's a long support cycle.

So was A320 ...

But even an A320 mobo supported a ryzen 5 3600.

I guess it's possible then.

THERE IS HOPE.

just like they squeezed 1 more generation out of A320, B350 and X370 mobos.

I guess they can do that with B450 and X470...

and if the bios chips can't fit, well they can discount zen 1 support (ryzen 1000).

Actually, I'm pretty sure I saw there was a lunch of 2 SKUs for AM3 this year. Really not joking, but I'd have to deep dive to find them again.

yeah but AMD blocked PCIE 4 support on 4xx and lower series boards at a later date and the comments in the above video seem to support they are going to pull the same stunt with support for Zen3 on anything but 5xx series boards which is very dissapointing

I guess I see this personally not as a stunt, but as a developing platform hitting road blocks that are either fiscally nonsensical or impossible to overcome.  And with agreements that board partners have (I am sure) that this is the best thing to do to keep all companies hitting good margins.

The PCIe 4.0 stuff was more because X470 boards generally couldn't, but B450 boards could. Also the issue that vendors couldn't validate boards in people's systems for it.

 

Most of this issue is simply because the B550 boards arrived 10 months late. AMD might reverse course, but I kind of doubt it. Supporting 3 separate architectures on a single microcode build would be rather difficult.

Maybe it was cause of signal degradation ?

Hopefully the AIB partners put AMD under enough pressure so they allow it at least

not complete support ...

just allow it .

yeah at the end of the day its all about money i suppose, but with the whole AM4 platform was and is sold on the excellent compatibility, with the whole intel tick tock stratergy having a new motherboard and little room to upgrade without replacing a load of extra stuff, it was nice to see, shame by the sounds of things theyre not letting motherboard manufacturers make the decision on this  like others have said, i built the wife an office pc with a VERY cheap a320 board and a 3600 and it works great, even with 3600mhz ram with xmp enabled, and was hoping to have that with my higher tier motherboard for Zen3, but alas

[Blademaster91]

It's all about the money because AMD is a company and they'd rather profit from the chipset selling you a new board.

Although there's no reason a X470 mobo shouldn't be compatible, like if you bough a 2xxx series CPU and X470 board to save money over a more expensive X570 board, you'd expect support for Zen 4000 series because AMD said so. Expecting board partners to spend money on making bios compatible on their own really sucks, and removing support after only 1 cpu upgrade cycle for X470 and B450 users is pulling the same crap that Intel does.

[Dabombinable]

When you also look at the fact that a fair few motherboard vendors have had to remove support for previous AM4 CPU to fit the 3000 series, and combine that with support being up to 2020 (and now extending into 2021), this really isn't a problem.

[TetraSky]

I wasn't planning on buying Zen3, since I do believe a CPU should last you more than a year or two. So this wouldn't affect me personally.

 

But man... That would suck. I can understand locking out much older boards like the 3xx series, but even b450 and x470? Come on AMD. You fucked us all up by taking your sweet time releasing the cheaper boards, forcing people on a budget to buy older motherboards... Ain't everyone that can afford to spend as much/more on a motherboard as they do on the CPU.

they might change their minds in the future when the CPUS are released in the market

Maybe they will if enough people complain. IIRC Zen3 will be AM4 (not 100% sure of that) so I'm sure some people with 300 and 400 series boards will complain about lack of support. 

I'm hoping they will even though I probably won't be buying Zen3.
