Server-grade DDR3L ECC LRDIMM kit

This 64GB kit contains two 32GB DDR3L 1600 modules built for servers and workstations that require ECC load-reduced memory. Each module uses a 240-pin DIMM form factor with a quad-rank x4 organisation and runs at 1.35V low voltage. It is not compatible with desktop or laptop computers.

Sustained-load behaviour with load-reduced ECC

The load-reduced design lowers electrical load on the memory bus, helping maintain signal integrity when all slots are populated under continuous workloads. ECC protection corrects single-bit errors on the fly, while the CL11 latency and 1600 MHz speed deliver steady throughput for virtualisation and database tasks.

Installation notes and common issues

Modules install in standard 240-pin DDR3 DIMM slots, but the system must explicitly support DDR3L ECC LRDIMM technology; many boards that accept regular registered ECC will not recognise these quad-rank modules. Verify the qualified vendor list and follow the manufacturer's channel-population rules before seating the pair.

Questions about this item

How much power does the 1.35V DDR3L LRDIMM kit draw under continuous server workloads?

Each 32GB module operates at 1.35V, so the dual-channel 64GB kit runs at the low-voltage DDR3L level to reduce heat and power draw during all-day operation.

What motherboard slot and chipset support do I need to install these 240-pin ECC LRDIMMs?

You need a server or workstation board with DDR3 ECC LRDIMM support, 240-pin DIMM slots, and a memory controller that accepts 4Rx4 quad-rank modules at 1600 MHz.

Can I mix these 4Rx4 LRDIMMs with standard 2Rx4 registered DIMMs already in my system?

No — load-reduced and registered DIMM types cannot be mixed; the memory controller requires identical rank and buffer architecture across all populated channels.
