ASRock lists RAM speed limits for Arrow Lake CPUs, non-K series tops out at DDR5-7200
We don't think this will be the big highlight

ASRock has shared the memory support for their upcoming ASRock Z890 Taichi motherboards, with the Core Ultra 200 K series supporting DDR5-9000 and the Ultra Core 200 Non-K series DDR5-7200.
The official memory QVL from ASRock has pointed out interesting details regarding the RAM speed limits for their new Z890 Taichi motherboard with the Intel Core Ultra 200 series. According to the list – and pointed out by Uniko’s Hardware – the Arrow Lake non-K CPUs will potentially have lower RAM speed limits than the Arrow Lake K CPUs. Specifically, the non-K processors will only be able to support DDR5-7200 memory speeds while the K variants will support overclocked memory speeds of up to DDR5-9066 MT/s.
Will lower RAM speed limits significantly affect the non-K CPU performance?
Normally, we have seen DDR5-6000 MT/s as the optimal option for both AMD and Intel processors, a good balance between price and value. While faster memory options like DDR5-7200 MT/s and DDR5-9000 MT/s are available, their price-to-value ratio is uncertain. The performance gains from a higher memory speed aren’t that significant. Usually, the only impact that you are looking at is with metrics like minimum or 1% low average frames per second in gaming. So, the lower memory speeds with the Arrow Lake non-K CPUs shouldn’t bother you much in a noticeable way.
RAM speeds do impact integrated GPU performance which can be an issue for users who plan to utilize Arrow Lake’s integrated GPU. We still have yet to hear about the iGPU inside the Arrow Lake series and see if it even is fit for gaming or not.
Generally, high-end motherboards, such as the ASRock Z890 Taichi, are usually chosen for their overclocking capabilities, which are optimized and best suited for K-series CPUs. As a result, the lower RAM speed limit for non-K series CPUs is likely to have little impact on the overall market. Overall, we don’t expect this difference in memory speeds to be a big deal breaker for most consumers.
