4GB DDR3L 1600 ECC UDIMM

This 4GB DDR3L 1600 ECC UDIMM module operates at 1.35V with CL11 latency and a 2Rx8 organisation. It is built for servers and workstations that require error-correcting unbuffered memory in the 240-pin DIMM form factor. The part replaces Samsung M391B5273CH0-YK0 and M391B5273DH0-YK0 modules. Each stick is tested for reliability before shipping.

Suits systems needing low-voltage ECC unbuffered

Administrators upgrading or repairing servers that specify DDR3L 1600 ECC UDIMM memory will find this module a direct match. It is not suitable for platforms that require registered or load-reduced DIMMs, for boards limited to standard 1.5V DDR3, or for consumer desktops that cannot use ECC memory. Buyers needing larger single-module capacities should verify their system's maximum supported density first.

1.35V DDR3L voltage decides compatibility

The 1.35V operating voltage is the critical specification; systems designed only for 1.5V DDR3 may not support this low-voltage module. Confirm the motherboard or server documentation lists DDR3L 1600 (PC3L-12800) ECC UDIMM support before purchase. The 2Rx8 rank structure and CL11 timing must also align with the platform's memory controller requirements.

Questions about this item

What motherboard slot does this 240-pin DDR3L UDIMM require?

This module fits a standard 240-pin DDR3 DIMM socket that accepts 1.35 V DDR3L memory.

Will this ECC UDIMM run in a system that currently uses non-ECC DDR3 1600 sticks?

The board must support ECC UDIMM operation; mixing ECC and non-ECC modules is not recommended and may prevent the ECC feature from functioning.

How can I confirm the module is detected at the correct 1600 MHz speed after installation?

Check the BIOS memory information or use a tool such as CPU-Z to verify the module reports DDR3-1600 (PC3L-12800) at CL11.
