AMD's Latest AGESA Update Removes PCIe 4.0 Support from Pre-X570 Motherboards
AMD's latest AGESA update, which is being seeded to motherboard manufacturers, culls efforts to implement support for PCIe 4.0 in boards not carrying the latest X570 chipset. Some motherboard manufacturers had enabled support for the new standard on existing B450 and X470 motherboards - some with limited support, as was the case on some of ASUS' motherboards, others with full support. However, these efforts from motherboard manufacturers went against AMD's strategy with their X570 platform - all in all, these "rogue additions" reduced one additional feature of new X570 motherboards over their older counterparts.
The new AGESA code carries the part number AM4 1.0.0.3 ABB, and will likely be reflected in manufacturers' release notes for new BIOS versions that incorporate the code - and remove added PCIe 4.0 functionality. Other changes in this AGESA code release include fixes for Destiny 2 gamers' woes, which were having a hard time getting the game to run properly on Ryzen 3000 processors. If you're an avid Destiny 2 player and want PCIe 4.0 support, you'll likely be reminded of Rick and Morty's pickle episode. If not, you can always defer these AM4 1.0.0.3 ABB updates, if your system is behaving properly.

If I owned a high end x470 board and planned to move to 3000 I'd be a little annoyed that amd didn't let the manufacturer implement it even though they had come out with 4.0 bios so it was probably working fine.
AIBs mentioned that some boards could meet the requirements. I thought it would be up to the board partners to figure this out. But in the end, I agree AMD is simply protecting themselves and as splash damage, gets to sell more x570 boards for the unadorned who think they need it.
If you absolutely need PCIe 4 support, stop being a cheapass mofo and shell out the damn cash for an X570 board. Otherwise, shut your damn mouth, because AMD doesn't owe you anything.
PCIe 4.0 doesn't need new wiring it's a question of signal integrity / trace length and it happens that many boards meet those requirements on their 1st PCIe slot , it's for the rest of the PCIe slots that things become tricky and where X570 chipset comes to play !
In this case, they could just have said, Everyone need to buy an X570 board on a new sockets. But still, you can update to a modern Ryzen on 3x0 series chipset with the only downside of not having a feature that you do not need.
Let say it's not the perfect scenario but it is in line with what they said all along. It's not like that come out of nowhere. And like many people specified, when PCI-E 4.0 will be required, these board will start to be outdated
Mobo manufactures dont even supports all I/O of chipset, but they will support next gen PCI-e in mobo. It only possible in fools heaven.
New high speed interfence dont new wiring then why we need new cable for 5G/10G Ehternet?? Cant we just download new cabel on those old cable??
Where is my Skylake CPU download?? My CPU already supports 84W TDP and so does my mobo. So where is my download??
Be real motherboard makers scarcely give a rats ass about the end user post sale ,we're lucky they bother updating the bios at all, they are not going to retest and re certify all their old boards , some already updated many times so multile versions of the same board too so they can prove pciex4 compatibility , they would f##$ up their own new motherboard sales and go against they're chip manufacturers guidelines.
And can anyone post an x470 board advertised as pciex4 compliant new or old, I think it doesn't exist except obviously in china as a hacked special.
So no , Amd didn't do anything wrong here.
Let me give you one example: Asus Crosshair IV AM3 supported Bulldozer CPU's and if I remember correctly even Piledriver worked but none of them worked perfectly which was expected.
So please explain to me why at that time AMD didn't do anything? I can give you a hint - they were demolished by Intel and needed every possible income.
IMO they disabled PCIe4 only so people buy x570 and nothing else.
If board makers tested it and found it works correctly (in this case it either works or it doesn't!) I don't see any problem.
the more I think about it,amd would win if nvidia came out with 3080ti soon.they'd get crushed in gpu power,but imagine people selling their coffee lakes for ryzen :laugh:
Are you saynig that we can download hardware like RAM or CPU??
and it's a separate issue of different kind.what does gpu vrm have to do with this,seriously ?
and pci-e lines are on the cpu.the hardware is there.
