What this module is

This is a 4GB DDR3L SODIMM rated at 1600MHz with ECC and a 1.35V operating voltage. It uses the 204-pin form factor and runs at CL11 latency. The module is an unbuffered replacement for Micron MT18KSF51272HZ-1G6K2 and is aimed at microserver, server or workstation laptops that require error-correcting memory.

Compatibility checks

Verify that your system accepts DDR3L SODIMMs at 1.35V and supports ECC unbuffered modules. Confirm the motherboard or laptop manual lists 1600MHz PC3-12800 as a supported speed and that the slot is a 204-pin SO-DIMM socket. Some platforms only accept non-ECC or 1.5V DDR3, so matching voltage and ECC type is essential before ordering.

Who this suits

This module suits owners of compatible microserver or workstation laptops needing a single 4GB ECC stick for maintenance or a modest capacity increase. It is not for systems that require registered or buffered memory, nor for platforms limited to 1.5V DDR3 without low-voltage support. Buyers needing higher densities or non-ECC memory should look elsewhere.

Questions about this item

Does the 4 GB DDR3L 1600 ECC SODIMM arrive as a single stick or do I need to buy anything else to install it?

The package contains one 4 GB 204-pin DDR3L 1600 CL11 1.35 V ECC unbuffered module; no extra parts or cables are required for installation.

Should I choose the 4 GB CL11 1.35 V version or look for a different capacity or speed for my microserver?

This module is a direct replacement for Micron MT18KSF51272HZ-1G6K2, so select it when your system calls for a single 4 GB DDR3L 1600 ECC SODIMM at 1.35 V.

What does the 1600 MHz PC3-12800 rating actually deliver once the stick is seated in a server board?

The module runs at DDR3L 1600 with CL11 timing at 1.35 V, providing ECC error correction and 12 800 MB/s peak bandwidth in compatible microserver or workstation slots.
