  • ECC registered design protects data integrity
  • Low-profile DIMM fits space-constrained builds

Samsung DDR4-2133 ECC registered DIMM

This 16 GB DDR4 module uses a 2Rx4 registered ECC design in a low-profile form factor. It is built for servers and workstations that require error-correcting memory with registered buffering. The DIMM operates at 2133 MT/s and is sold in new condition.

DDR4-2133 registered ECC constraints

Registered ECC modules only function in platforms whose chipsets and firmware explicitly support registered buffering and error correction. Standard desktop boards typically ignore or reject this memory type. The 2133 MT/s speed is the baseline DDR4 data rate; higher system speeds require modules rated beyond this value. Buyers who need non-ECC unbuffered memory for a consumer motherboard cannot use this product.

Highlights

  • 16 GB capacity for demanding workloads
  • DDR4-2133 speed for responsive data transfer
  • ECC registered design protects data integrity
  • Low-profile DIMM fits space-constrained builds

Questions about this item

Should I choose this 16GB DDR4-2133 module or a higher capacity stick?

This module provides 16GB in a single DIMM; add more sticks of the same spec if your board has free slots and you need more total memory.

What does the 2133 speed mean once the module is installed in my desktop?

The memory will run at up to 2133 MT/s; actual speed depends on your motherboard and CPU memory controller, which may clock it lower.
