16GB DDR4 ECC RDIMM for Servers

This 16GB DDR4 3200 module is an A-Tech replacement for Samsung M393A2K40EB3-CWE. It targets servers and workstations that require registered ECC memory for data integrity. The single-rank 1Rx4 organisation suits platforms qualified for this density. Buyers needing unbuffered UDIMMs or non-ECC modules should look elsewhere.

Standard voltage and registered buffering

Operating at 1.20V, the module runs at standard DDR4 voltage without elevated power draw. Registered buffering places a light load on the memory controller, helping stability in multi-DIMM configurations. No active cooling or special airflow is specified; typical server chassis airflow is sufficient. Systems not validated for registered DIMMs will not support this module.

288-pin DIMM with Samsung chipset

The stick uses a 288-pin DDR4 DIMM form factor built on Samsung chipset components. CL22 latency is set at the rated 3200 speed. Installation follows standard keyed DIMM slots; no extra cables or brackets are involved. Verify your platform’s qualified-vendor list for this exact part number before purchase, as unlisted systems may not train the module.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify the system recognises the full 16 GB at 3200 MHz in BIOS.

What maintenance or replacement will this ECC registered module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace it with another 1Rx4 DDR4 3200 RDIMM of matching voltage.

What limit appears first when this 1.2 V CL22 module runs sustained workloads?

The CAS latency of 22 cycles at 3200 MHz sets the baseline response time; thermal throttling only occurs if chassis airflow cannot dissipate the standard DDR4 power envelope.
