4GB DDR3L ECC RDIMM Server Memory

This 4 GB DDR3L registered ECC module runs at 1333 MHz with CL9 latency and 1.35 V operation. It is built for servers and workstations that require error-correcting registered memory. The single 240-pin DIMM uses major-brand chips in a 2Rx8 configuration. Buyers needing non-ECC or unbuffered DDR3 for desktop boards cannot use this module.

Capacity and headroom for DDR3L 1333 platforms

The 4 GB capacity suits light virtualisation, file serving or legacy application workloads on compatible DDR3L platforms. Registered buffering and ECC protect data integrity under sustained loads. Systems requiring larger memory footprints or higher speeds than PC3L-10600 will need additional modules or a newer platform.

Build integration with 240-pin DDR3L slots

The module fits standard 240-pin DDR3 DIMM slots that support 1.35 V registered ECC memory. It replaces Micron MT18KDF51272PDZ-1G4, MT18KSF51272PDZ-1G4 and MT18KSF51272PDZ-1G4M1 part numbers. Platforms limited to 1.5 V DDR3 or consumer unbuffered memory will not accept this DIMM.

Questions about this item

Will this DDR3L 1333 ECC RDIMM work in a system that currently uses standard DDR3 1333 registered modules?

This module runs at 1.35 V DDR3L, while standard DDR3 operates at 1.5 V; mixing voltages can cause instability, so verify your platform supports DDR3L before installing.

How can I confirm the 4 GB module is detected and running at 1333 MHz with ECC active after installation?

Enter the BIOS or UEFI and check the memory information screen — it should show 4 GB, 1333 MHz, ECC enabled and registered (RDIMM) mode.

What comes in the box and do I need any extra brackets or cables for a 240-pin server DIMM slot?

The package contains one 4 GB DDR3L 240-pin ECC RDIMM; no additional brackets, cables or adapters are required for a standard server DIMM slot.
