Performance metrics when frequency is reduced
Performance metrics when frequency is reduced
I noticed differences in timing patterns between DDR4 models. Most 2666MHz chips use 19-19-19-43 timing, while higher speeds like 3000MHz and 3200MHz follow 16-18-18-38. Since your chipset only supports 2666MHz, the memory will default to 2133MHz. Enabling an XMP profile can push it up to 2666MHz. You're asking whether a 3200MHz RAM with that timing works at the same speed if the chipset restricts it to 2666MHz.
In my analysis, lower frequency tends to match with reduced CL timing. I’m considering purchasing RAM with minimal CL but my motherboard can handle up to 2666MHz. It seems the CL listed for 3200MHz models refers to a 2133MHz base speed without optimization.
We lack certainty; review the SPD profiles for the sticks and verify. Cas latency isn't related to frequency support.
