SAMSUNG M393A1K43DB2-CWE DDR4-3200 8GB ECC Registered server RAM

SKU CH-4K38-SYXST MPN M393A1K43DB2-CWE

8 GB DDR4 ECC registered server memory running at 3200 MHz with a 288-pin interface

  • ECC protection prevents data corruption with built-in error correction
  • Registered design stabilises heavy workloads through buffered signal control
  • DDR4 3200 MHz speed delivers high bandwidth for server tasks
  • 8 GB capacity fits standard DIMM slots for easy upgrades
  • 288-pin RDIMM form factor ensures broad platform compatibility

Product identity

This Samsung DDR4-3200 module delivers 8 GB of registered ECC memory for servers and workstations that require error correction and signal buffering. The x18 organisation and single-rank layout suit platforms qualified for PC4-25600 speeds.

Bundled impact

No accessories or software are included with the module; the ECC and registered functions are built into the DRAM itself and change system behaviour by enabling error detection and reduced electrical load on the memory controller.

Build and connectivity

The 288-pin DIMM uses standard gold-edge contacts and a green PCB that fits any DDR4 registered DIMM slot. Registered signalling improves stability in multi-DIMM configurations, while ECC operation adds data-integrity protection for continuous workloads.

Questions about this item

Will the registered buffer or ECC logic on this M393A1K43DB2-CWE module require periodic replacement?

No, the registered buffer and ECC logic are solid-state components with no moving parts and no scheduled replacement interval.

What is the first limit reached when this 3200MHz DDR4 module runs at full load continuously?

The JEDEC-rated 3200 MT/s data rate is the ceiling; the module cannot exceed its specified PC4-25600 speed under sustained use.
