4GB DDR3L ECC UDIMM for Servers

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses a 1Rx8 unbuffered ECC design on a 240-pin DIMM. The stick targets administrators upgrading compatible Dell servers or workstations that require error-correcting memory.

Capacity and headroom

A single 4GB module suits light virtualization, file serving, or legacy application workloads. Memory-intensive databases, heavy virtualization hosts, or high-throughput compute nodes will exhaust this capacity quickly. The 1Rx8 organization provides standard density for this generation.

DDR3L 1600 interface limits

The PC3L-12800 interface caps bandwidth at the DDR3L 1600 data rate. Systems limited to lower DDR3 speeds will downclock the module automatically. Platforms requiring registered DIMMs or higher voltages cannot use this unbuffered 1.35V part.

Questions about this item

Will this 4 GB DDR3L 1600 CL11 1.35 V ECC UDIMM work in a system that currently uses DDR3 1600 ECC UDIMMs?

Yes, it matches the DDR3 1600 MHz PC3L-12800 ECC UDIMM specification, so it can run alongside existing DDR3 1600 ECC UDIMM modules.

How can I confirm the module is running at 1600 MHz with ECC active after installation?

Check the BIOS or UEFI memory information screen; it should report 1600 MHz speed, CL11 timing, 1.35 V voltage and ECC enabled for the installed 4 GB module.

Does the package contain only the single 240-pin DIMM or are extra parts included?

The box contains one 4 GB 240-pin DDR3L ECC UDIMM module; no brackets, cables or additional accessories are supplied.
