24GB DDR5 memory modules were installed on AMD Ryzen 7000

24GB DDR5 memory modules were installed on AMD Ryzen 7000 – the system recognized them, but refused to work

enthusiasts decided find outwhat happens if you install a set of working DDR5, consisting of two new 24 GB RAM modules, each on an AMD Ryzen 7000 board. In short: the system recognized them, but refused to work with such memory.

RAM manufacturers began to produce RAM modules with unusual capacities of 24 and 48 GB. This can be used to create memory kits with a total capacity of 48 GB (2 × 24 GB), 96 GB (2 × 48 or 4 × 24 GB) and even 192 GB (4 × 48 GB). Currently, these memory configurations are only supported on the LGA 1700 platform for 12th and 13th Gen Intel Core processors.

As an experiment, a Corsair Vengeance DDR5-5600 48GB (2×24GB) RAM kit was installed in a system with an AMD Ryzen 5 7600X processor and an ASUS ROG Strix B650E-E gaming motherboard with BIOS version 1222. Surprisingly, the machine passed the POST check and was even able to run 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, joy was premature as the Windows operating system never booted. The download didn’t go beyond the Boot Manager, which is responsible for loading Windows into RAM. At this point the PC gave an error indicating a problem with the hardware.

Technically, AMD Ryzen 7000 processors only support up to 128GB of RAM. A few months ago, 12th and 13th Gen Intel Core processors had the same limitations. Apparently these limitations are not hardware related, they are software related. Now manufacturers of motherboards based on Intel chipsets of the 600 and 700 series are announcing the readiness of their products to work with 24 and 48 GB RAM modules. This has already been reported by companies such as MSI, Gigabyte and ASUS, which have released or will soon release new BIOS versions with support for non-standard memory modules. AMD can also add official support for these RAM modules to its boards based on the X670, X670E, B650 and B650E chipsets by working with these manufacturers.
