  • 16 GB capacity supports demanding workloads

16GB DDR4 RDIMM for servers

This Samsung module delivers 16GB of DDR4 memory in a registered DIMM form factor with ECC. It is intended for server platforms that require registered, error-correcting memory at the PC4-21300 standard.

Installation notes for registered DIMMs

Registered DIMMs must be used with motherboards that support registered memory and ECC; they will not function in standard desktop boards that expect unbuffered modules. Mixing registered and unbuffered DIMMs on the same channel will prevent the system from posting.

Verify platform support before ordering

Confirm that your motherboard and processor explicitly support DDR4 RDIMM modules with ECC at the PC4-21300 speed grade. Check the maximum supported capacity per slot and the total number of registered DIMMs the platform can address.
