16GB DDR4 2666 ECC SODIMM for servers

This 16GB DDR4 2666MHz ECC SODIMM module is built for server and workstation systems that require error-correcting memory. It operates at 1.20V with a CL19 latency and uses a 260-pin SO-DIMM form factor. The module is an unbuffered ECC design compatible with AMD and Intel platforms.

Straightforward slot installation

Installation follows the standard SODIMM procedure: power down, open the access panel, align the notch with the key in the slot, and press firmly until the side clips lock. The most common issue is a loose fit that prevents the clips from engaging; reseating the module usually resolves this. Verify that the system BIOS recognises the full 16GB capacity after boot.

Confirm ECC SODIMM support first

Before ordering, check that your laptop or server motherboard explicitly supports unbuffered ECC DDR4 SODIMM memory at 2666MHz. Some platforms only accept non-ECC modules or registered DIMMs, which are electrically different. Consult the system manual or vendor documentation for the exact memory qualification list to avoid a mismatch.

商品問答

How can I confirm the 16GB DDR4 2666MHz ECC SODIMM is running at CL19 and 1.20V after installation?

Open Task Manager or a tool like CPU-Z and check the memory tab; it should show 2666 MT/s, CL19 timings and 1.20 V on the SPD readout.

What comes with the module and is anything else required for a laptop upgrade?

The box contains one 16 GB 260-pin DDR4 ECC SODIMM; no extra cables, brackets or software are needed — just a compatible slot.

Should I choose the Samsung M474A2K43BB1-CTD or M474A2K43DB1-CTD version for my server?

Both part numbers are listed as compatible equivalents; this single 16 GB module replaces either one.
