SAMSUNG M393A2G40DB0-CPB 16GB DDR4 2133MHz ECC Reg desktop RAM

SKU CH-TE66-CBY4M

16 GB DDR4 ECC registered memory module running at 2133 MHz for desktop systems

  • 16 GB DDR4 capacity for demanding workloads
  • 2133 MHz DDR4 speed for responsive data access
  • ECC registered design detects and corrects memory errors
  • Samsung original module ensures component reliability
  • Desktop form factor fits standard DIMM slots

ECC Registered DDR4 Memory

This 16 GB DDR4 module uses ECC Registered technology to detect and correct single-bit errors. It is designed for desktop workstations that require data integrity for professional workloads. The memory operates at a 2133 MHz clock speed. It is not intended for standard consumer desktops without ECC support in the chipset and CPU.

Standard Voltage Thermal Profile

The module runs at the standard DDR4 voltage with no additional cooling requirements beyond normal case airflow. Power draw scales with the 2133 MHz frequency and registered buffer operation. Acoustic output depends entirely on the system fans installed by the builder.

No Accessories Or Software Included

The package contains only the memory module itself in protective packaging. There are no cables, adapters, heatspreaders or configuration utilities supplied. Installation relies on the motherboard firmware to recognise the ECC Registered timings automatically.

Questions about this item

How do I install this 16GB DDR4 2133MHz ECC Reg module and what step do people often get wrong?

Align the notch on the module with the key in the DIMM slot, press straight down until the retention clips click, and the step people miss is ensuring both clips snap fully locked rather than catching on one side.

What maintenance or replacement will this M393A2G40DB0-CPB memory need later?

No routine maintenance is required; keep the slot and contacts dust-free with compressed air, and replace the module only if memory diagnostics report uncorrectable ECC errors.

What limit appears first on this Samsung DDR4 ECC Reg stick under sustained heavy workloads?

The 2133MHz data rate and registered buffer latency set the throughput ceiling, so sustained bandwidth tops out at the rated JEDEC speed before thermal throttling becomes a factor.
