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.

And just for the record - no matter what the reason for this PCIe 4.0 fiasco is, AMD really managed it poorly. 'Managed' OFC is a gross overstatement here.
anywho the point of AMD doing this is because it knows who is going to take the brunt of bad publicity should anything go wrong with PCIe4.0 on X470 mobos it won't be the Manufacturers it'll be AMD
News flash for you , those older boards don't actually need to have PCIe 4.0 onboard ( read chipset that supports PCIe 4.0 ) because they can use the PCIe 4.0 lanes provided by the CPU at least for their 1st PCIe slot ( wich usually meets the signal integrity requirements for PCIe 4.0 due to the proximity with the CPU ) .
Next time make sure you educate yourself before posting some random BS at least it will make your comments less embarasing !
Like I said before even according to them their lower end boards look to be better. At the same time someone buying a $70-$100 (Asus tax $130) is less likely to want to spend greater then that amount on a capable NVME.
There are plenty of boards on this list who meet signal integrity for Gen 4 x16 and on top of that this list only shows what ASUS has validated so it's not final ( unless ASUS wants us to believe that their low end boards have better built quality than their top of the line boards ) + this is only one board vendor !WTF is you talking about man ? Guy pulls some generic technical term out of internet in order to make himself look like he knows something and thinks people are goin to fall for his BS !
Here is how PCIe lanes are distributed for 3000 series CPUs , so fist your eyes on it and educate yourself !

CPU provides one direct x16 Gen 4 lane to the first PCIe slot on the mobo ( assuming it meets the signal integrity requirements incase on a PCIe slot built to respect PCIe 3.0 specifications ) and one direct X4 Gen4 PCIe lane for NVMe or SATA . It doesn't work like this ? LOL man you are a joke !
Anyways enough time lost with trolls of your kind , in the trash bin you go !
We have proof that PCIe 4.0 works perfectly fine on X470/B450 so yeah thats all i need to know as far as i'm concerned . www.google.com/amp/s/www.techpowerup.com/257380/asus-begins-enabling-limited-pcie-gen-4-0-on-amd-400-series-chipset-motherboards?amp
Sooo yeah last time you checked MyDrivers wasn't ASUS ? Cool cause i would had been surprised aswell if they where .... now enlighten me how is this related to the discussion exactly ???Since when there was a criteria that ALL boards have to be compatible in order for something to be supported ? Asking because if we follow this logic , Strix X370/B350-i didn't offer any video output for APUs yet i didn't saw AMD killing APU support for the entire X370/B350 platforms .... this logic doesn't make sense , does it ?
It's crazy to see all the lengths you peoples go through to not admit the obvious wich is this is purely a money motivated decision . Had any , ANY other company made the same decision you same peoples would had roasted this company based on the principles of anti-consumer behaviour , greedy practices and what have you , but when AMD is doing this stuff you all suddenly act like this :
and did you see the actual prices of x570 ? entry level costs as much as a upper-mid end x470
