AMD Working on AGESA Update for 24GB and 48GB DDR5 Memory Module Density Support
AMD is working on the AGESA 1.0.0.7 BIOS update that should resolve issues and bring support for 24 GB and 48 GB DDR5 memory modules and kits on the AM5 platform. The latest report, coming from Twitter, suggest that AMD is working hard on the AGESA release, so motherboard manufacturers could push BIOS updates early next month or in May. While Intel's 600- and 700-series motherboards are happily working with 24 GB and 48 GB DDR5 memory modules and kits, allowing users to use up to 192 GB (4x48 GB) of memory in their systems, it comes as a surprise that AMD did not release an official, or even a BETA BIOS update for such modules.
There were already reports that such 24 GB and 48 GB DDR5 modules are having issues on AMD's AM5 platform and while the BIOS can detect the memory, it simply will not boot into Windows. This latest report originally comes from hardware leaker chi11eddog over at Twitter, and suggests that AMD and its motherboard partners are well aware of the issue and the AGESA BIOS firmware v1.0.0.7 should bring full support for so-called "non-binary" 24 GB and 48 GB DDR5 memory modules.

As lower-volume parts, they don't bring anything new to the table - 32GB DIMMs are cheaper. Perhaps that will eventually change, but at current pricing they have no reason to exist and without popularity as a driving force to bring prices into line, they won't be popular. Chicken and egg scenario right there!
48GB DIMMs are welcome as they push the maximum RAM per socket up by 50% - still disappointing that it's not 64GB DIMMs but it's better than nothing.
Those capacities have been publicly shown for quite a while now, so AMD should've known about it for a very long time. As the article notes they are supported by all major memory IC vendors.
It'd be nice if it "just worked" but history has taught us that it quite frequently doesn't.
It would be great if they could do something about the performance and stability of using all for DIMM slots as I have heard that is a bit of a nightmare,.....
As for 24GB and 48GB DDR5, that really should have been sorted earlier on even though it's not a common configuration.
Locally there is at least one website that lists the Corsair 48GB (2 x 24) in 5200 and 5600 speed, with and without RGB and the same for the 96GB (2 x 48), as in stock. The website says nothing about compatibility. So they could be bought for an AMD Zen 4 system without knowing there is an issue at present. Having said that, as the Intel motherboards need a BIOS update to run this memory it's quite possible that one of these boards without that update might not boot into Windows either.
AMD on the other hand, not only doesn't have support, but hadn't even begun to work on support them until the internet gave a collective "WTF AMD"? Not even the multitude of press releases from Intel board partners a month ago, trumpeting the fact that their Intel boards natively support these modules, was sufficient to cause AMD management to even consider supporting these module sizes. That's an embarrassing and unnecessary dropping of the ball from AMD.They don't.
