ASUS Announces BIOS Support for Ryzen 5000/4000 Processors

[Uskompuf]

ASUS today announced BIOS support and updates for a variety of motherboards supporting the new AMD Ryzen 5000 and 4000 series CPUs. Matching the new Ryzen 7 5800X3D, which has a dedicated 96 MB L3 cache, AMD has released AGESA version 1.2.0.6b to improve system performance. Many ASUS 500, 400, A320 and X370 series motherboards already have BIOS updates with this new AGESA version. Other compatible models will receive corresponding BIOS updates by March 25th.

All CPUs in this series are recognized by ASUS mainboards of the 400 and 500 series via existing BIOS updates - also with AGESA version 1.2.0.6b. The updates can be downloaded from the ASUS support website. Previous generation ASUS motherboards will receive support for these new CPUs according to the table below:

No B350 support when both A320 and X370 gets it, Asus going for the Amd route in late 2020: "If I'll support only part of what I'm supposed to support then I'll both look like the good guy and spare my firmware developers some work".

Same stuff from Amd when it initially didn't want to support 300 and 400 chipset and ended up looking like the good guys for supporting 400 and same stuff from Asus that decides not to support arguably their most sold first gen AM4 chipsets, the bigger chunk of their 300 series user (b350 owners) will eventually upgrade so why would they support a chipset with nothing to gain in return?

Why don't they support for B350 too? Seems quite strange.

It's the same thing on Giga end, so my guess is this is AMD push not OEM.

Makes you wonder why they would do that? More so given A320 is getting it!

I have a B350 board in one machine, Asus prime B350-plus specifically. I can change clocks on my gen 1 Ryzen 5 1600, on the fly, using the old version of Ryzen Master and the memory bandwidth bench in AIDA doesn't make sense relative to the max theoretical speed of the RAM I have in the machine (4 x 4GB single rank Corsair 2.66ghz), when it's overclocked in that way. If I overclock via the bios, the memory bandwidth stays constant.

That is the theoretical limit of 2.66GHZ DDR4 in dual channel should be 42.6GB/s but AIDA benchmarks at 50GB/s+ with it at 3.9-4GHZ all core clock and it scales with the clock speed, e.g memory bandwidth is higher at an higher clock speeds.

I've wondered about it for a while if there is something in B350 that could be responsible for this, if there is a bug somewhere or how that can be possible?

All this undermine's AMDs biggest selling point. Why bother buying into a platform with multi year upgrades if you cant get them without new mobos each time? Who would buy into a platform with the hope that they can get the later chips as an upgrade, assuming enough people scream about it.

More BIOS flashing! While I like how AMD is allowing board with legacy chipsets to run newer CPUs, I am however starting to find that there are way too many BIOS updates coming from AMD. Too many. Just by sticking on to the Ryzen platform for 4 years, I’ve flashed more BIOS than 2.5 decades of me fiddling with computer hardware. AMD seems to have gone AGILE style with their BIOS updates and I generally find it very uncomfortable to keep having to flash a motherboard just for improving stability with hardware, stability in system, and bug fixes. The process is simple, but a bad BIOS update can mess things up badly, and it can happen unexpectedly. For example, I’ve recently ran into this issue where I had to flash the X470 Taichi board so that it supports a 3900X. While the BIOS update appears to be successful, but it somehow got corrupted for no/ unknown reasons. As a result, the CPU started acting weird by parking 10 of its cores all the time, and only using 1 or 2 cores at a fraction of its clockspeed even when running Cinebench R20 Multithreaded bench. It took a roll back to an older BIOS version and reflash with the same latest BIOS (that started this mess), to fix the issue. The fortunate thing is that the BIOS flash did not brick my motherboard, but that left a bad taste in my mouth.

I picked up this new bios for my board a few days ago and waiting until the weekend to install.

If I still had my AMD system with my Rog Strix B350-F mobo I would be kinda pissed/salty about this if they really wont include B350.

I thought v 1….7 was the new one with support?

1.2.0.6b or c supports 5800X3D

1.2.0.7 will be support for Zen 3 on older boards I believe.

Imagine someone who bought an A320 mobo back in 2016 now gets the opportunity to install a 5600x in it. In the meantime 1151 has been obsolete for years now... Intel should definitely learn from this.

They won't and their users have no problems with it. Same as Nvidia users that is the one common bond they share

I have no idea but I'm on the complete end of the spectrum with my B350.

No issues overclocking RAM with good results and also my Zen 2 running 4.4ghz 1.28V stable.
Maybe you have some sort of topology limitation with 4 dimms? I tried mixing hynix CJR and Samsung E-Die with decent results but it was surely suboptimal for OC on my B350.

I have the bios for two days already, the one ASRock sent me supports the new chip and has this AGESA version.

Not exactly, Gigabyte announced support for the X570, B550, A520, X470, B450, and A320 motherboard; Asus is supporting the X370 too, according to their announcement. Also MSI previously added support for Vermeer to their B350 mobos, so they're likely going to be compatible with most of these new processors (except for the Cezanne based 5500, right now no series 300 motherboard supports Cezanne afaik). Support for Zen 3 on series 300 has remained sketchy since AMD's belated announcement, but I guess it's fair to assume that it's up to the single partner to decide whether they want to make their motherboards compatible or not.

EDIT:
AMD is rumoured to have stopped Asrock from doing this back in 2020 when they released some beta BIOS for a couple of X370 mobos. It might be true or not, but it's likely no coincidence that they've allowed OEM to discretionarily unlock their series 300 only now, AM4 is on its way out and few people would actually grab a new motherboard with no future upgrade path whatsoever, on the other hand unlocking the old motherboards might convince some people to make a drop-in upgrade this year, rather than switching to Alder Lake (which at least offers a limited upgrade path to Raptor Lake).

Do you have AIDA64 ? If so post bandwidth please.

Also did you ever try overclocking it with ryzen master? I have the version I'm using, can share it with anyone interested, want to see if the increase in memory bandwidth is repeatable on other b350 boards and newer ryzen chips.
