SAMSUNG

SAMSUNG M393A2G40DB0-CPB3Q 16GB 2Rx4 DDR4-2133 ECC Registered desktop RAM

SKU CH-M5T6-HBM7N

16 GB DDR4 ECC Registered memory running at 2133 MHz with CL15 latency

  • ECC protection prevents data corruption
  • Registered signal processing improves system stability
  • Dual-rank X4 architecture increases memory density
  • 2133 MHz transfer rate enables fast data throughput
  • CL15 CAS latency reduces access delay

Product Identity

This Samsung DDR4 module delivers 16 GB of ECC Registered memory in a single 2Rx4 stick. It suits workstations and entry-level servers that require error-correcting registered DIMMs rather than standard unbuffered desktop RAM.

Thermals and Power

Operating at 1.2 V with a CL15 latency profile, the module runs at standard DDR4 voltage and generates modest heat under normal workloads. No additional cooling is required beyond typical chassis airflow for registered memory.

Sustained Load Behaviour

The PC4-17000 rating at 2133 MHz provides consistent bandwidth during extended compute tasks. ECC and registered signal processing maintain data integrity and electrical stability across long-running jobs such as virtualization hosts or scientific calculations.

Highlights

  • ECC protection prevents data corruption
  • Registered signal processing improves system stability
  • Dual-rank X4 architecture increases memory density
  • 2133 MHz transfer rate enables fast data throughput
  • CL15 CAS latency reduces access delay

Questions about this item

How is the Samsung M393A2G40DB0-CPB3Q installed and which step is often missed?

Align the notch with the DDR4 slot key, press firmly until both retention clips click, and ensure the registered module is fully seated so the ECC circuitry initialises correctly.

What maintenance or replacement will this 16 GB 2Rx4 DDR4-2133 ECC registered module need later?

No routine maintenance is required; if a memory test reports correctable ECC errors that become uncorrectable, replace the module.

What limit appears first under sustained load with this CL15 PC4-17000 registered memory?

The CL15 latency at 2133 MHz sets the throughput ceiling before thermal throttling becomes a factor.
