Server Memory Module

This 8 GB DDR3 1866 MHz ECC RDIMM is built for servers and workstations that require registered memory with error correction. It operates at the standard DDR3 voltage of 1.5 V and uses a 240-pin DIMM form factor. The module is not compatible with desktop or laptop computers.

Registered Dual-Rank Design

The 2Rx8 dual-rank organisation and registered buffer help stabilise the memory bus in multi-module configurations typical of server boards. Major-brand chips are used throughout and each stick undergoes quality-assurance testing before shipment. The 240-pin connector fits only DDR3 RDIMM slots keyed for registered memory.

Standard Voltage Operation

Running at 1.50 V with a CAS latency of CL13, the module draws normal DDR3 power without requiring elevated voltage settings. Error-correcting code and the registered interface add minimal overhead while protecting data integrity under sustained workloads. Thermal output remains within typical DDR3 limits for passively cooled server chassis.

Questions about this item

What speed does the DDR3 1866 PC3-14900R standard cap at in practice?

The module runs at 1866 MHz with a PC3-14900R rating and CL13 latency, so the bus transfers data at that rate when the server platform supports it.

What slot and physical clearance does this 240-pin RDIMM need?

It fits a standard DDR3 240-pin DIMM socket; the registered design adds a small register chip, so verify the motherboard has enough height clearance for full-height RDIMMs.

How is the module installed and what step is often missed?

Power down, open the chassis, align the notch with the key in the 240-pin slot, press firmly until both latches click, then confirm the system BIOS recognises the ECC registered capacity.
