03/12/2023 at 7:30 a.m. by Valentin Sattler – AMD supposedly wants to publish an AGESA update so that the new DDR5 bars with 24/48 GiB memory also work with Ryzen 7000 processors. Accordingly, support from AGESA version 220.127.116.11 is planned.
At the beginning of the year, Corsair and Micron presented new DDR5 modules, which are equipped with 24 and 48 GiB memory for the first time. As a result, the DDR5 generation deviated from the usual scheme of powers of two (8, 16, 32) for the first time. PC hobbyists can thus equip their system more flexibly with main memory, and thanks to the new 48 GiB modules, new maximum values can also be achieved. But the new RAM bars have to be supported by the mainboard, and that’s exactly what’s still a problem.
UEFI update for AMD motherboards
Although some of the bars stated that they are compatible with AMD’s Ryzen 7000 processor, problems can still arise there. At the moment, DDR5 RAM with 24 or 48 GiB memory can only be used safely with Intel CPUs. With AMD’s AM5 platform, on the other hand, this should be possible with a UEFI update: According to leaker @g01d3nm4ng0 active on Twitter, the new memory type should be supported with AGESA version 18.104.22.168.
However, most AM5 mainboards are currently still based on AGESA version 22.214.171.124c, while UEFIs based on 126.96.36.199 are still in the test phase. If support for DDR5 RAM with 24 and 48 GiB per bar is actually only available with version 188.8.131.52, players would have to wait a while before they can use the new RAM with their Ryzen 7000 system.
The history: AMD Ryzen 7000: DDR5 RAM with 24 and 48 GiB can still cause problems
At least so far, the selection of corresponding modules is not too large anyway. The PCGH price comparison currently only lists 12 corresponding models, all of which come from Corsair. The cheapest kit, which consists of two 24 GiB modules, costs EUR 3.76 per GB. Comparable kits of other sizes are available from 3.44 euros and are therefore slightly cheaper. On the other hand, a clearer surcharge is required for the new 48 GB bars: Corsair sells these from 4.12 euros per GiB.
