Intel's Arrow Lake CPUs Offer Enhanced RAM Speeds with CUDIMM

The new Intel Core Ultra 200S series supports DDR5-6400 with CUDIMM, but non-K CPUs are limited to DDR5-7200.

Intel's Arrow Lake processors, part of the Core Ultra 200S series, officially support DDR5-6400 memory speeds with CUDIMM technology.
Standard UDIMM sticks are limited to DDR5-5600 unless overclocked using XMP, while CUDIMM allows higher stability at increased speeds.
ASRock's Z890 motherboards can support DDR5-10133+ with overclocking and liquid cooling, though this requires K-series processors.
Non-K Arrow Lake CPUs will top out at DDR5-7200, a limitation compared to the K-series' potential for DDR5-9066.
Despite the RAM speed differences, most users may not notice significant performance changes in everyday applications.
