ASUS Announces BIOS Support for Ryzen 5000/4000 Processors
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:

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