8GB DDR4 ECC SODIMM for servers

This 8GB DDR4 2133MHz ECC SODIMM module is built for server and workstation laptops that require error-correcting memory. It operates at 1.20V with CL15 latency and uses a 260-pin unbuffered design. The module replaces Samsung M474A1G43DB0-CPB and M474A1G43EB1-CPB part numbers.

Straightforward SODIMM installation

Installation follows the standard SODIMM procedure: power down, open the memory slot, align the notch, and press firmly until the clips lock. The main risk is purchasing ECC memory for a system that only supports non-ECC modules, which will prevent boot or disable the ECC function. Verify your platform accepts unbuffered ECC SO-DIMMs before fitting.

Confirm ECC support and slot count

Check your laptop or mobile workstation documentation to confirm it supports DDR4 ECC unbuffered SO-DIMMs at 2133MHz. Ensure a free 260-pin slot is available and that the BIOS does not restrict ECC functionality. Systems limited to non-ECC memory will not work correctly with this module.

Questions about this item

How can I verify the 260-pin DDR4 2133MHz ECC module is running at CL15 and 1.20V after installation?

Enter the system BIOS or use a tool like CPU-Z to confirm the memory reports DDR4 2133 (PC4-17000), CL15 timings, 1.20V voltage, and ECC active.

What ships with the 8GB DDR4 2133MHz ECC SODIMM and what must I source separately?

The box contains one 8GB 260-pin DDR4 2133MHz ECC unbuffered SODIMM module; no cables, brackets, or tools are included.

Which capacity and speed version should I choose to match Samsung M474A1G43DB0-CPB or M474A1G43EB1-CPB?

Select the 8GB DDR4 2133MHz (PC4-17000) ECC unbuffered SODIMM — it is the direct equivalent for both Samsung part numbers.
