For some time now, announcements from motherboard manufacturers have been multiplying concerning the support of 24/48 GB memory kits. Indeed, we have the right to the communiqués of MSI, Gigabyte and also from ASRock. However, each time, it only concerns Intel platforms in 600 and 700 series. But what happens if you install this type of DDR5 module on an AMD card?
DDR5 in 24/48 GB on AMD: well recognized in the bios, but does not boot!
MEGAsizeGPU was curious to see what effects the installation of 24/48 GB memory had on an AMD platform. For that, the little curious one thus obtained a Corsair Vengeance kit of 2×24 Gb and assembled it on AMD card. For the exercise, it was an Asus ROG Strix B650E-E coupled with a Ryzen 5 7600X. During the operation, the motherboard was running with the bios in version 1222.
On power up, obviously, no problem, the user even had access to the bios in which the memory was well recognized. As you can see, the A2 and B2 DIMMs have the correct RAM capacity. On the other hand, it should be noted that AMD CPUs are capable of officially managing 128 GB of memory. With these 2×24 GB, we are technically in the clear.
However, it is when booting into Windows that things get complicated. As we can see, the system does not manage to go beyond the Windows boot manager. The latter indicating a hardware problem. In short, we feel that it would be possible to do something to have full compatibility with this type of RAM. It would not be surprising to see bios blossoming in the near future from the various motherboard suppliers.
