  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 16GB ECC RDIMM adds capacity for heavy server workloads
  • Registered DDR4 2400MHz CL17 ensures signal integrity at speed
  • 2V operation keeps power draw low in dense racks
  • 1Rx4 single-rank layout simplifies memory channel population
  • Replaces Samsung M393A2K40BB1-CRC and M393A2K40CB1-CRC modules directly

Server Memory Upgrade

This 16GB DDR4 ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. It operates at 2400MHz with a CL17 latency and runs at the standard 1.2V. The single-rank 1Rx4 organisation uses major-brand chips on a 288-pin module.

Sustained Workload Stability

Registered buffering and ECC circuitry keep data integrity intact during continuous, multi-threaded server workloads. The module is tested to maintain rated speed and voltage without throttling under prolonged load. Major-brand components and rigorous validation support dependable operation in always-on environments.

Compatibility Gate

This module replaces Samsung M393A2K40BB1-CRC and M393A2K40CB1-CRC parts; verify your system supports DDR4 2400MHz ECC RDIMM 1Rx4 memory before purchase. The 288-pin form factor fits only DDR4 DIMM slots. Buyers needing non-ECC or unbuffered memory for consumer boards cannot use this module.

Questions sur cet article

How much heat and power does a 1.2V 16GB DDR4 2400MHz ECC RDIMM draw when running continuously in a server?

At the standard DDR4 voltage of 1.2V this registered module operates within the normal thermal envelope for 2400MHz server memory; registered buffering reduces electrical load on the memory controller, helping sustain stable temperatures during all-day workloads.

What must my motherboard provide to accept this 288-pin DDR4 2400MHz ECC RDIMM?

The board needs a DDR4 RDIMM slot, support for ECC registered memory, and a memory controller qualified for 2400MHz PC4-19200 operation at 1.2V.

Will this 1Rx4 CL17 16GB DDR4 2400MHz module work in a system that already has different-rank DDR4 ECC RDIMMs installed?

Mixing ranks is platform-dependent; the module itself is a single-rank 1Rx4 design at CL17, so the memory controller must support mixed-rank populations at 2400MHz — check the system manual for qualified configurations.
