On a previous report, AMD is said to be looking to limit next-gen Socket AM5 motherboards to support only DDR5 with the newest AMD Ryzen 7000 CPUs. AMD has not officially confirmed this but it seems like their partners are revealing more information regarding this possibility.
Memory maker Apacer indicates in their marketing slide that AMD’s Zen4 desktop parts will support DDR5-5200. This means that out of the box, DDR5-4800 and DDR5-5200 will be supported without any overclocking ala XMP profile. This extends to platforms which may not support memory overclocking as well should AMD go that route. For those who may be used to the freedom that AMD platforms have, Intel platforms are limited to certain RAM speeds e.g. DDR5-4800 on non-enthusiast parts.
DDR5-5200 is fairly fast but should brands go for faster speeds, AMD is also looking to set their ownOC profile which veers away from Intel’s XMP technology with AMD EXPO.
