ASUS has officially validated DDR5-7200 JEDEC memory support across its Intel 800-series motherboard lineup when paired with Core Ultra 200S processors, raising the guaranteed baseline specification beyond Intel's standard DDR5-6400 configuration. The validation covers the complete range including Z890, B860, and H810 chipsets. Intel's Arrow Lake-S CPUs ship with JEDEC DDR5-6400 support out of the box. ASUS says it has extended this through enhanced PCB routing, signal integrity optimization, and improved power delivery design. Crucially, this higher speed operates at JEDEC standard specifications without requiring XMP or EXPO profile activation, ensuring official warranty coverage and stock-level stability.

ASUS demonstrated the capability using a Core Ultra 7 265K paired with the mainstream/entry-level PRIME Z890-P motherboard from the Z890 lineup and a Kingston 32 GB (2×16 GB) DDR5-7200 kit. The configuration was running at 1.10 V with CL58-58-58-115 timings using a 1:2 memory controller ratio. Despite the relatively loose latencies, the setup maintained full stability under RunMemtestPro stress testing. The performance jump from DDR5-6400 to DDR5-7200 delivers approximately 800 MT/s additional bandwidth and while not revolutionary for all workloads, memory-sensitive applications should see improvements.
