Server memory kit for DDR3 platforms

This 64GB kit contains two 32GB DDR3 1866 modules built as ECC Load Reduced DIMMs for servers and workstations. Each module uses a 4Rx4 quad-rank layout and runs at the standard 1.5V. The dual-channel kit is designed for systems that specifically require LRDIMM registered memory.

Thermals and power in normal operation

Operating at 1.5V, the modules draw standard DDR3 power for this density and speed. Load Reduced buffering reduces electrical load on the memory bus, which helps maintain signal integrity in high-capacity configurations. No active cooling is included; airflow through the server chassis normally keeps temperatures within specification.

What the kit changes for the operator

Populating two slots with 32GB LRDIMMs increases total memory to 64GB while consuming only two DIMM sockets, leaving room for further expansion if the platform supports it. ECC and load-reduced operation improve data integrity and bus stability under heavy workloads. Systems that do not support DDR3 ECC LRDIMM cannot use this kit.

Questions about this item

How do I install the 240-pin DDR3 LRDIMM modules in the correct server channels?

Power down the server, open the chassis, align each 240-pin module with the keyed slot, press firmly until the retention clips lock, then follow the system manual for dual-channel population order.

Will the ECC LRDIMM chips need any firmware updates or periodic replacement?

The ECC Load Reduced DIMM modules have no user-serviceable firmware and no scheduled replacement interval; they run until a module fails or the server is decommissioned.

At what point does the 1.5V DDR3 1866 CL13 quad-rank kit hit its thermal or bandwidth ceiling under sustained load?

Sustained workloads are limited first by the DDR3 1866 MT/s bus bandwidth and the quad-rank electrical loading, not by the 1.5 V operating voltage.
