Capacity & Form Factor

This RIMLANCE RES23400S8C16 module provides 16GB of DDR4 capacity in a SODIMM form factor. It is intended for servers, workstations and NAS units that require ECC protection in a compact slot layout. The single 1Rx8 rank keeps the electrical load light for dense memory configurations. Buyers needing higher density per slot or registered DIMMs will not be served by this part.

Thermals Noise & Power

Operating at 1.2V, the module runs at standard DDR4 voltage without elevated power draw. ECC operation adds a modest overhead but does not change the thermal profile compared with non-ECC equivalents at the same speed. No active cooling is required beyond normal chassis airflow. Systems with restricted airflow or passive cooling should still verify case thermals independently.

Build & Connectors

The 288-pin edge connector matches the DDR4 SODIMM socket specification and uses major-brand DRAM components. Unbuffered design means direct connection to the memory controller without a register chip. CL21 latency at 2933MHz (PC4-23400) is the rated timing; tighter timings are not guaranteed. Installers must confirm the platform accepts unbuffered ECC SODIMMs before purchase.

Questions about this item

How do I install this 288-pin DDR4 SODIMM module, and what step do people often get wrong?

Align the notch on the module with the key in the SODIMM slot, press firmly at an angle until the gold contacts are fully hidden, then press down until the side clips click into place.

What maintenance or replacement will this 16GB ECC SODIMM need later?

No routine maintenance is required; the module is solid-state. Replace it only if system diagnostics report correctable or uncorrectable memory errors.

What limit shows up first under sustained use with this CL21 2933MHz module?

The CAS latency of CL21 and the 2933MHz data rate set the timing boundary; sustained workloads will hit this latency ceiling before voltage or thermal limits become factors.
