SAMSUNG M393A4K40EB3-CWE 32GB DDR4 server RAM 3200 MHz 288-pin

SKU CH-GV1Y-RYMED MPN M393A4K40EB3-CWE

Registered 32 GB DDR4 server module runs at 3200 MHz with ECC and 1.20 V operation

  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity for dense server configurations
  • 3200 MHz DDR4 throughput matches PC4-25600 bandwidth spec
  • 20 V operation reduces power draw per 32 GB module
  • 288-pin DIMM form factor fits standard server memory slots

Server-grade 32 GB DDR4 module

This Samsung M393A4K40EB3-CWE module delivers 32 GB of DDR4 memory rated at 3200 MHz for server platforms. The registered ECC design adds error correction and signal buffering that multi-socket systems require. A single 288-pin DIMM keeps slot count low while providing high capacity per channel. It targets administrators who need reliable density for virtualization or database workloads.

1.20 V operation and thermal profile

Running at 1.20 V, the module stays within standard DDR4 voltage limits to reduce power draw per DIMM. Registered signalling lowers electrical load on the memory controller, which helps thermals in fully populated chassis. Dual-rank organisation spreads activity across banks, avoiding hot spots during sustained throughput. No active cooling is included, so airflow must come from the server chassis.

Registered ECC changes data integrity

On-board ECC detects and corrects single-bit errors before they reach the application layer. Registered buffering isolates the memory bus from the controller, allowing larger DIMM populations per channel. The PC4-25600 rating confirms the 3200 MHz transfer rate under JEDEC timings. Systems without registered-memory support cannot use this module.

Domande su questo articolo

How is the 288-pin DDR4 module seated, and what step do installers often miss?

Align the notch with the slot key, press straight down until both retention clips click, then verify the module sits flush; the step most often missed is confirming both clips have fully engaged.

What maintenance or replacement will the registered ECC DIMM need over its service life?

No routine maintenance is required; if a correctable error count rises or the module fails POST, replace the 32 GB stick — there are no user-serviceable parts on the board.

What limit appears first when the 3200 MHz RDIMM runs sustained heavy workloads?

The 1.20 V operating voltage and registered buffer keep thermals in check, so the DDR4-3200/PC4-25600 data rate remains the bounding limit before thermal throttling would occur.
