Historically, memory support for a specific generation of Intel CPUs is all the same across all models, but this may not be the case if ASRock’s QVL (Qualified Vendor List) for DDR5 memory modules is anything to go by. While the Core Ultra 200 non-K series is yet to be announced at this point in time, it looks like these processors will not have the same level of memory support as their K-series counterparts.
Intel Core Ultra 200 Non-K Memory Support Revealed

Search for any ASRock Z890 motherboard’s support page and you’ll see a list of modules verified to work on the motherboard/CPU combination, and here it is split into two sections – one for the K series, while the other is for the non-K series. The latest QVL list for the former goes up to 9066MT/s, while the latter is maxed out at 7200MT/s instead.
While it is technically not a great news if you are planning to obtain one of these chips, a ceiling of 7200MT/s is hardly going to affect most users – anyone who has the money to spend on these highly expensive modules will most likely opt for the K series processors to maximize the performance potential of their systems.
Officially, ASRock has not given any reason for the limits on specific models, though this list may change given that Intel has yet to announce the non-K models of the Arrow Lake-based processors, which is likely expected in the coming months.
