SAMSUNG M393A2K40CB2-CTD 16GB DDR4-2666 ECC REG DIMM

SKU CH-8B9J-8CYZ4

Provides 16 GB of DDR4-2666 ECC registered memory for server workloads

  • 16 GB capacity supports larger workloads
  • DDR4-2666 speed enables faster data transfer
  • ECC registered design protects data integrity
  • Samsung manufacturing ensures component reliability
  • OEM module built for server and workstation use

Server-grade DDR4 ECC memory

This 16 GB DDR4-2666 registered DIMM includes error-correcting code for data integrity in server and workstation platforms. The module is built by Samsung for enterprise environments that require registered buffering and ECC protection.

OEM packaging only

The unit ships without retail accessories, heatsinks or configuration software. System builders must verify motherboard support for registered ECC DDR4 before installation.

DDR4-2666 registered ECC constraint

Registered modules cannot be used in consumer desktop boards that lack ECC and register support. Mixing registered and unbuffered DIMMs is not supported by the DDR4 standard.

Questions about this item

Will the ECC registered DIMM require periodic replacement under normal server workloads?

The 16GB DDR4 module has no moving parts and is rated for continuous operation, so it does not have a scheduled replacement interval.

What limit appears first when the 2666 MT/s memory runs at full load for extended periods?

The registered buffer and ECC logic add a small latency overhead that becomes the primary bottleneck before thermal or power limits are reached.

How much heat does the 16GB DDR4-2666 ECC REG DIMM produce when installed in a populated server chassis all day?

The module operates within standard JEDEC voltage for DDR4, generating typical heat levels that are managed by normal server airflow.
