4 GB DDR3 ECC UDIMM for servers

This module adds four gigabytes of DDR3 1600 memory with ECC error correction to compatible servers and workstations. It uses an unbuffered 240-pin DIMM form factor and runs at the standard 1.5 V voltage. The dual-rank x8 organisation suits platforms that accept 2Rx8 modules. It is not compatible with desktop or laptop computers.

Capacity and headroom

A single 4 GB stick provides a modest capacity increase for systems with free DIMM slots. It handles light virtualisation, file serving and typical office workloads without exhausting memory. Larger databases, heavy virtualisation clusters or memory-intensive rendering will exceed this module alone and require additional sticks or higher-density modules.

Thermals noise and power

Standard 1.5 V DDR3 operation keeps power draw low and heat output minimal in normal server use. The unbuffered design has no active cooling components, so the module runs silently and relies on chassis airflow. Typical operating temperatures stay well within DDR3 limits when the system ventilation follows the manufacturer's guidelines.

Questions about this item

Will this 240-pin DDR3 1600 ECC UDIMM run alongside existing DDR3 ECC unbuffered modules in my server?

It uses the standard 1.5V DDR3 voltage and 240-pin UDIMM form factor, so it can share slots with other DDR3 ECC unbuffered sticks; the system will clock all modules to the lowest common speed.

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

Enter the BIOS or UEFI on boot and check the memory information screen — it should show 4 GB at 1600 MHz (PC3-12800) with ECC enabled.

Does the package include only the single 4 GB stick or are heat spreaders and cables supplied as well?

The box contains one 4 GB 2Rx8 DDR3 1600 ECC UDIMM module; no heat spreaders, cables or additional hardware are included.
