A-Tech 16GB DDR4 3200MHz ECC RDIMM 1Rx4 for Samsung M393A2K40DB2-CWE M393A2K40DB3-CWE Server Memory

SKU CH-5J8Y-M831C

16GB DDR4 3200MHz ECC registered DIMM with CL22 latency and 1.2V operation for server workloads

  • Capacity16GB
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 16GB ECC RDIMM adds reliable server capacity
  • DDR4 3200MHz CL22 delivers responsive throughput
  • 2V standard voltage keeps power draw low
  • 1Rx4 single-rank layout simplifies memory configuration
  • 288-pin DIMM fits registered DDR4 slots

Targeted Server Upgrade

This A-Tech module delivers 16GB of DDR4 3200MHz registered ECC memory built for server and workstation platforms. It uses a 1Rx4 organisation with CL22 latency at the standard 1.20V operating voltage. The 288-pin DIMM fits DDR4 registered DIMM slots and relies on major-brand chips for dependable operation.

Direct Samsung Replacement

The module is specified as a compatible equivalent for Samsung M393A2K40DB2-CWE and M393A2K40DB3-CWE part numbers. It matches the original capacity, speed, voltage and registered ECC configuration slot-for-slot. The upgrade is worthwhile when a system requires registered DIMMs and the existing slots support DDR4 3200MHz operation.

Sustained Load Stability

Registered buffering reduces electrical load on the memory controller during continuous operation, while ECC corrects single-bit errors that can accumulate under heavy workloads. The 1.20V standard voltage keeps power draw predictable across long runs. Systems that cannot accept registered DIMMs or require a different rank configuration cannot use this module.

Questions sur cet article

Does the 288-pin DDR4 DIMM fit a standard server memory slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor that matches standard registered server slots.

What BIOS setting or slot order is required when installing this 1Rx4 registered ECC module?

Install in the correct channel order for your platform and enable ECC in BIOS; registered modules must be seated fully until the retention clips click.

Will the 1.2V major-brand chips need replacement under continuous server loads?

The 1.20V DDR4 chips are validated for continuous operation; no scheduled replacement is needed unless a module fails.
