SAMSUNG M393A2K40CB2-CTD 16GB DDR4 server memory

SKU CH-8YTW-1QMWD

Adds 16 GB of DDR4 ECC registered memory to a server with a 288-pin DIMM slot running at 2666 MT/s

  • 16 GB capacity supports larger server workloads
  • DDR4-2666 speed handles demanding data tasks
  • ECC registered design protects against data errors
  • Single 288-pin DIMM simplifies installation
  • Samsung DDR4 quality built for server environments

Server-grade DDR4 DIMM

This Samsung module delivers 16 GB of registered ECC memory in a single 288-pin DIMM. It is built for servers and workstations that require error correction and signal buffering for stable operation.

Thermals and power in normal use

DDR4 memory operates at low voltage and generates minimal heat during typical workloads. The registered design reduces electrical load on the memory controller, contributing to efficient power draw without active cooling.

ECC registered requirement

This module only functions in platforms that support registered ECC DDR4 memory. Consumer motherboards and laptops without ECC and registered capability will not accept it.

Questions about this item

How is the 288-pin DDR4 DIMM installed, and which step do people often get wrong?

Align the notch on the module with the key in the server DIMM slot, press straight down until both retention clips click, and verify the module sits evenly; the step most often missed is failing to open both clips fully before insertion, which can leave one side unlatched.

What maintenance or replacement will the 16 GB registered ECC module need later?

No routine maintenance is required; the module should only be replaced if memory diagnostics report correctable ECC errors that exceed the platform threshold or if a capacity upgrade is needed.

What limit appears first on the PC4-21300 registered DIMM under sustained load?

The registered buffer and ECC logic add a small latency overhead, so sustained throughput is bounded by the DDR4-2666 data rate and the memory controller's maximum supported rank count per channel.
