4GB DDR3 1333MHz ECC UDIMM for Servers

This 4GB DDR3 1333MHz ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at 1.5V with CL9 latency and uses a 2Rx8 rank configuration. The 240-pin DIMM form factor fits standard DDR3 slots in compatible enterprise platforms.

Compatibility checks before ordering

Verify that your system supports DDR3 1333MHz (PC3-10600) unbuffered ECC memory and accepts 240-pin UDIMM modules. Confirm the motherboard or server documentation allows 2Rx8 rank organisation and 1.5V operation. Ensure there is a free DIMM slot and that the platform does not require registered or load-reduced memory instead.

Upgrading from non-ECC or lower-capacity DDR3

This module replaces non-ECC DDR3 DIMMs or smaller-capacity ECC sticks in supported servers and workstations. The jump is worthwhile when data integrity matters for critical workloads or when the platform demands ECC unbuffered memory. It does not suit systems that require registered RDIMMs, LR-DIMMs, or a different DDR generation.

Questions about this item

What comes in the box and is anything else needed to install this module?

The package includes one 4GB DDR3 1333MHz ECC UDIMM; no extra parts are required for installation in a compatible 240-pin slot.

Should I choose a different capacity or speed for my server?

This module is a single 4GB stick at 1333MHz; select additional identical modules to reach your system's supported total capacity and populate channels evenly.

What does the 1333MHz rating mean once the module is running in my machine?

The memory operates at 1333MHz with CL9 latency and 1.5V, delivering the rated DDR3 throughput when the platform's memory controller is set to that speed.
