ASUS officially increases memory speed support for Intel Core Ultra 200S to 7200 MT/s on its 800-series motherboards. With higher speeds, ASUS 800-series motherboards will help achieve higher bandwidth and better stability.
ASUS Pushes Memory Speeds Further, Allowing Up To DDR5 7200 MT/s Configuration On Its 800-Series Motherboards for Intel Core Ultra 200S
The Core Ultra 200S, aka Arrow Lake S, desktop CPUs support JEDEC 6400 MT/s out of the box. However, due to excellent memory controllers and great motherboard designs, Intel CPUs are able to push the memory speed way beyond this frequency.
This, however, achieving higher than advertised speeds needs some changes in the BIOS, such as enabling XMP/EXPO profiles. Achieving even higher memory clocks is also possible, but it isn't always guaranteed. With XMP 3.0 support, DDR5 memory is able to achieve 6400+ MT/s speeds, but officially, Intel doesn't guarantee over 6400 MT/s out of the box.
JEDEC (Joint Electron Device Engineering Council) sets the official industry standards for memory, but today, ASUS has guaranteed that its Intel 800-series motherboards will guarantee 7200 MT/s of memory speed out of the box. This means ASUS is able to achieve 7200 MT/s successfully without any XMP profile, delivering higher bandwidth, more performance, and stability out of the box for the Core Ultra 200S processors.
This is likely as a result of better PCB traces, signal integrity, and power delivery that enhances the system's stability with higher RAM speed. ASUS showcased it via CPU-Z, using the budget PRIME Z890-P motherboard with Intel Core Ultra 7 265K processor.
It used a 32 GB (2x 16 GB) DDR5-7200 kit by Kingston, with the memory controller running in a 1:2 ratio (memory controller at 1800 MT/s). The latencies were CL58-58-58-115, and the memory was operating at a low 1.10 V. So, the timings look kinda loose, but that's what happens when you want to achieve higher frequency on a low voltage.
The RunMemtestPro tests show that the memory kit was able to run at 7200 MT/s with great stability, indicating that ASUS 800-series motherboards are ready to handle this speed without any hassles. In real-world applications, an 800 MT/s improvement may introduce noticeable uplifts in certain circumstances, but shouldn't be that impactful.
