Not so long ago, 24 and 48 GB DDR5 memory modules began to appear on sale, with the help of which a regular desktop PC can be equipped with 192 GB of RAM. There are more and more such solutions, but they are only suitable for systems based on Intel – computers based on AMD turned out to be out of work, which is confirmed by both manufacturers and users.
Corsair lists its 24GB and 48GB Vengeance DDR5 memory modules as compatible with 12th and 13th generation Intel Core processors only. At the same time, AMD Ryzen 7000 processors, which also support DDR5 memory, are not mentioned. Other manufacturers of memory modules have not yet announced kits with modules for 24 or 48 GB.
It is also worth noting that SK hynix, announcing 24 Gb DDR5 memory chips in 2021, which form the basis of 24-/48-GB memory modules, announced cooperation with Intel. An Intel spokesman then noted that the companies are working together to provide more capacious memory to their customers. On the contrary, Micron, when announcing 24 and 48 GB DDR5 memory modules last December, mentioned support for AMD EXPO overclocking profiles.
Motherboard manufacturers are also talking about support for new modules only by systems based on Intel chips. MSI, Gigabyte and ASUS have already released or will soon release new BIOS versions with support for unusual memory modules for their motherboards based on Intel 600 and 700 series chipsets. But no information has been received about the corresponding updates for boards based on the X670, X670E, B650 and B650E chipsets. In addition, 24 and 48 GB solutions are not mentioned in the compatibility lists of memory modules from motherboard manufacturers.
An enthusiast decided to find out what would happen if we installed a DDR5 memory kit of two modules of 24 GB each on an AMD Ryzen 7000 board. with AMD Ryzen 5 7600X processor and ASUS ROG Strix B650E-E Gaming motherboard with BIOS version 1222.
Surprisingly, the machine passed the POST check and was even able to start UEFI/BIOS. The motherboard firmware was able to correctly determine the total amount of RAM and the density of each of the two memory modules. Unfortunately, the joy was premature, as the Windows operating system was never able to boot. The download did not go beyond Boot Manager, which is responsible for loading Windows into RAM. At this point, the PC gave an error indicating a problem with the hardware.
Apparently, the limitations for AMD processors are not hardware, but software, and in the future, computers based on AMD Ryzen 7000 will also receive support for 24 and 48 GB memory modules. Micron has formally confirmed this. But when this will happen is not clear. In the meantime, only Intel users can enjoy the increased amount of RAM, but AMD users are left behind.
