Check DDR5 latency settings for compatibility
Adjusting subtimings like tRDD_S, tRRD_L and tFAW mostly removes CL from consideration, affecting performance little.
Shown by the images above, it's also possible to simply set one value because its x4 portion of trrd_s ensures optimal performance. This works well even with high-end systems like DDR3 2800+ and newer platforms might behave differently. Tighter RAM settings usually help the best, but if you plan to overclock right away, using XMP won't be a waste—just go straight for OEM parts from Hynix/Klevv or TeamGroup 5600C46 with guaranteed chips if available. If you later need it working, an XMP setting around 6000/6400C32 is handy since it’s easy to apply and gets you about 80% there.
