MODULES MUST BE ORDERED AND INSTALLED IN GROUPS OF FOUR for Quad Channel mode.
Depending on which processor you install, different memory modules are required. Intel Xeon W processors require ECC RDIMMs. Intel Core i7/i9 processors require non-ECC UDIMM.
Only Intel Xeon x2xx Series (Cascade Lake) and I7/i9 (Cascade Lake) processors can use memory modules built with 16Gb density DRAM. BIOS/firmware updates and/or specific board revisions may also be required.

KCP4xxNS8/16 and KCP4xxND8/32 are only supported on systems with Core i7/i9 10th Gen (Cascade Lake) processors.
Mixing non-ECC UDIMM and ECC RDIMM within the same system is not supported.
Actual memory speed depends on the installed processor type.
