16GB DDR4 ECC SODIMM for Servers

This 16GB DDR4 2133MHz CL15 ECC SODIMM module is built for server and workstation systems that require error-correcting memory. It operates at the standard 1.20V DDR4 voltage and uses a 260-pin SO-DIMM form factor. The unbuffered design suits platforms that support ECC without registered DIMMs.

Suits ECC-capable laptops and compact servers

This module fits AMD and Intel platforms that accept unbuffered ECC SODIMMs at 2133MHz. It is not for consumer laptops or desktops that lack ECC support in the memory controller. Buyers who need non-ECC memory or higher speeds should look at a different specification.

Verify ECC support and slot availability

Check that your system’s CPU and chipset explicitly support unbuffered ECC SO-DIMM operation before ordering. Confirm the motherboard has a free 260-pin DDR4 SO-DIMM slot and that the BIOS recognises ECC modules. The module replaces Samsung part M474A2K43BB1-CPB.

Questions about this item

What motherboard slot and voltage does this 260-pin 1.20V DDR4 SODIMM require?

It fits a standard DDR4 SO-DIMM socket and runs at the DDR4 standard 1.20 V.

Will this unbuffered ECC module work in a laptop that only supports non-ECC memory?

Most consumer laptops ignore the ECC bits, so the module will usually run as non-ECC, but verify the manual first.

How can I confirm the module is detected at 2133 MHz with CL15 timings after installation?

Check the memory tab in CPU-Z or the BIOS main screen; it should show 2133 MHz and CL15.
