Installing 24GB DDR5 Modules on AMD Ryzen 7000 Platform Springs Mixed Results—POSTs but Doesn't Boot
Over the past month, memory manufacturers started releasing DDR5 memory modules of 24 GB and 48 GB densities, which make up 48 GB (2x 24 GB), 96 GB (2x 48 GB or 4x 24 GB) and even 192 GB (4x 48 GB) capacities. There's only one catch—these modules only work with 12th Gen Core "Alder Lake" and 13th Gen Core "Raptor Lake" processors, as their memory controllers support a maximum of 192 GB of memory, and 24/48/96 GB DIMM densities. MEGAsizeGPU decided to find out what happens when one of these kits is installed on an AMD Ryzen 7000 "Zen 4" platform.
A Corsair Vengeance DDR5-5600 48 GB (2x 24 GB) memory kit was installed on a machine consisting of an AMD Ryzen 5 7600X processor, and an ASUS ROG Strix B650E-E Gaming motherboard (BIOS version 1222). It turns out that the machine POSTs, and is able to start the UEFI setup program. Here, the program is able to display the correct 48 GB memory amount, and the memory density of each of the two modules. The trouble is, Windows would not boot, and does not go past the Boot Manager. It halts with an error message that indicates a hardware problem.
AMD Ryzen 7000 series processors technically have a 128 GB maximum memory size limit. Until a couple of months ago, so did 13th Gen and 12th Gen Intel Core processors, which means that this may not be a hard limit, even for AMD, and the company could work with motherboard manufacturers on firmware-level updates to enable support for 24 GB and 48 GB memory modules to at least operate under the 128 GB limit (think 2x 24 GB, 4x 24 GB, or 2x 48 GB). The introduction of 24 GB memory modules improves choices for PC enthusiasts, as it's now possible to have 48 GB of memory using faster single-rank DIMMs (2x 24 GB). It also strikes a middle-ground between 32 GB (2x 16 GB) and 64 GB (2x 32 GB).

Everytime there is a problem with new AMD hardware, it inevitably ends up being poor Windows employement, which then later gets fixed after AMD gets blasted in the media. Every time. This is no coincidence. This is corruption.
On the other side, Windows is at a crossroads. Its commitment to backwards compatibility causes it to be bogged down by a LOT of legacy code making it exceptionally unwieldy, and to make things even worse, contains a very significant amount of third party licensed code that Microsoft can't touch.
Does Microsoft face the wrath of losing a lot of compatibility with older Windows software and clean up their act, or are we going to receive Windows 8 reskins forever from now on? Time will tell.
It could be as simple as intel send hardware samples to intel along with lots of money to get shit working earlier, or it could be something more nefarious - but without any evidence, conspiracies are just imagination
Honestly, we're at a point where there is no guarantee of stability because the RAM is always pushed too hard and the mainboard bios isn't tuned enough to mitigate it.
It's a law of the universe these days
Although i question why you think it's "slow" when the comments on the thread are excited about how fast it is given the RAM amount
