Arrow Lake non-K CPUs may suffer from lower RAM speed limits — ASRock QVL shows RAM up to DDR5-7200 as opposed to DDR5-9066 for K-series chips

Core Ultra 200S CPU.

Uniko's Hardware brought a peculiar detail of the ASRock Z890 Taichi motherboard's RAM support to the attention of the wider tech sphere and how it rather uncharacteristically changes between Intel Core Ultra 200S (codenamed Arrow Lake) processors.

To be specific, it seems that only Arrow Lake K-series Lake CPUs can support overclocked RAM speeds up to DDR5-9066, while Arrow Lake non-K parts will instead top out at DDR5-7200—quite a downside on such a premium board and for a DDR5 platform in general.
