4GB DDR3L 1600MHz ECC UDIMM

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V low-voltage operation. It is built as an unbuffered ECC UDIMM using a 1Rx8 rank and major-brand chips. The 240-pin DIMM is designed for server and workstation systems that require error-correcting memory.

Capacity and headroom

The single 4 GB stick adds modest capacity for light virtualization, file services or legacy application workloads. ECC protection guards against single-bit errors in always-on environments. Systems needing larger memory pools or higher bandwidth will exhaust this module quickly.

Build fit

The module fits standard 240-pin DDR3 DIMM slots and operates at the DDR3L 1.35 V specification. It replaces the listed HP part numbers directly without adapter or converter. Verify your platform supports unbuffered ECC UDIMMs before installation.

Questions about this item

Will this DDR3L 1600MHz ECC UDIMM run at 1.35V in a server that currently uses 1.5V DDR3 modules?

This module operates at 1.35V. It is a DDR3L low-voltage part. If your server only supplies 1.5V the module may not function correctly; check the platform documentation for DDR3L support before installing.

How can I verify the 4GB 1Rx8 CL11 stick is recognised and running with ECC active after installation?

Enter the BIOS or UEFI and confirm the slot shows 4GB at 1600MHz with ECC enabled. In the OS, tools such as dmidecode on Linux or WMI on Windows will report the module as ECC unbuffered, 1Rx8, CAS 11.

Does the single 240-pin DIMM ship alone or with extra parts such as a heatsink or installation tool?

The box contains only the 4GB DDR3L 1600MHz ECC UDIMM module. No heatsink, bracket or tool is included. The DIMM is ready to install directly into a compatible 240-pin server slot.
