  • 260-pin SO-DIMM form factor fits compatible laptop and microserver slots
  • Single-rank 1Rx8 organisation enables efficient memory controller access

ECC DDR4 SODIMM for Microservers and Workstations

This 4 GB DDR4 ECC SODIMM runs at 2133 MHz with CL15 latency and operates at 1.2 V. It uses a 260-pin unbuffered single-rank design built with major-brand DRAM ICs. The module targets microservers, mobile workstations and NAS devices that require error-correcting memory.

Check ECC SODIMM support and slot availability

Verify that your system explicitly supports DDR4 ECC unbuffered SODIMMs before ordering. Standard consumer laptops often disable ECC functionality or accept only non-ECC modules. Confirm the motherboard or chassis has a free 260-pin SO-DIMM slot and consult the manual for population rules.

Suits ECC-capable compact servers and NAS units

This module fits builders upgrading an ECC-enabled microserver, mobile workstation or NAS appliance that uses DDR4 SODIMMs. It will not work in systems that lack ECC support or require registered DIMMs. Buyers needing higher capacity per slot or non-ECC memory for a standard laptop should look elsewhere.

Questions about this item

Does the 260-pin SODIMM arrive alone, or are any tools or adapters included?

The module ships as a single 4GB stick; no tools, adapters or extra components are supplied.

I see only one 4GB 2133 MHz ECC option — how do I know it suits my build?

This is the sole capacity and speed offered under part number NE-SS-1623; confirm your system accepts DDR4 ECC unbuffered SODIMMs before ordering.

What does the CL15 rating mean for everyday workloads on a compatible laptop?

CL15 indicates 15-cycle CAS latency at 2133 MHz, giving standard DDR4 response times for ECC error correction during typical multitasking.
