4GB DDR3L ECC UDIMM for Servers

This 4GB DDR3L 1333 module delivers error-correcting memory for server and workstation platforms that require unbuffered ECC DIMMs. It operates at 1.35V low voltage and uses a 2Rx8 Micron chipset organisation. Builders maintaining compatible DDR3L systems can use it to replace a Micron MT18KSF51272AZ-1G4M1 stick.

Straightforward 240-pin installation

The module fits standard DDR3 DIMM slots and requires no special tools beyond normal anti-static precautions. Most issues arise when the platform expects registered or fully buffered DIMMs instead of unbuffered ECC, or when the BIOS lacks support for 1.35V low-voltage operation. Verifying the motherboard memory list before purchase avoids these mismatches.

Unbuffered ECC with 1.35V operation

The decisive specification is the combination of ECC unbuffered architecture and DDR3L 1.35V voltage. Systems that require registered ECC, standard 1.5V DDR3, or non-ECC memory will not accept this module. Match both the ECC type and the low-voltage requirement to ensure compatibility.

商品問答

How can I verify the module is running at 1333 MHz with ECC active after installation?

Check the BIOS memory information or run a tool like CPU-Z; it should report DDR3L 1333 (PC3L 10600), CL9 timings, 1.35 V and ECC enabled for the 4 GB stick.

What exactly ships in the package and do I need any extra brackets or cables?

The box contains one 4 GB DDR3L 1333 ECC UDIMM (240-pin DIMM, 2Rx8, Micron chipset); no brackets, cables or additional parts are required.

My server manual lists both 1.35 V and 1.5 V DDR3 DIMMs — which voltage version should I select?

Choose this 1.35 V DDR3L module; it matches the Micron MT18KSF51272AZ-1G4M1 spec and is designed for low-voltage server platforms.
