Server DDR3 ECC RDIMM

This 8 GB DDR3 1866 MHz registered ECC module is built for servers and workstations that require error-correcting registered memory. It operates at 1.5 V with a CL13 latency and uses a dual-rank x4 organisation on a 240-pin DIMM form factor.

Registered DIMM compatibility

The stick fits only DDR3 server or workstation platforms that support registered ECC RDIMMs; it will not work in desktop or laptop systems. Each module occupies one DIMM slot and follows the platform's channel population rules, leaving remaining slots available for further capacity expansion.

Standard voltage thermals

Running at the standard 1.5 V DDR3 voltage, the module draws typical registered DIMM power without needing extra cooling beyond normal server airflow. The registered buffer adds negligible latency while maintaining signal integrity under sustained workloads.

Questions about this item

How does the CL13 latency affect performance under sustained server workloads?

CL13 indicates a 13-cycle CAS latency at 1866 MHz, which determines the minimum delay before data becomes available during continuous read or write operations.

What is the power draw and thermal output when this module runs continuously at 1.5 V?

The module operates at the standard DDR3 voltage of 1.5 V, and registered DIMMs of this type typically draw only a few watts each, producing minimal additional heat inside a server chassis.

Which motherboard slot and chipset features are required for this 240-pin registered ECC module to function?

A server or workstation motherboard with DDR3 RDIMM slots, 240-pin DIMM sockets, and a chipset that supports registered ECC memory is required; desktop and laptop boards will not accept this module.
