128GB DDR3L ECC LRDIMM Kit

This 128GB kit contains four 32GB modules built for DDR3L servers and workstations. Each module runs at 1600 MHz with a CAS latency of 11 and operates at 1.35 volts. The load-reduced design and quad-rank x4 organisation are intended for high-density server platforms.

Server and workstation upgrades only

The kit suits administrators expanding memory in compatible DDR3L ECC LRDIMM systems that accept 240-pin registered modules. It will not work in desktop computers, laptops, or any platform that requires non-ECC or unbuffered memory.

Load-reduced quad-rank architecture

The 4Rx4 load-reduced layout reduces electrical load on the memory bus, allowing the full 128GB capacity to be installed in supported quad-channel server boards. Verify that your system specifies LRDIMM support before purchasing.

Questions about this item

When will the 4Rx4 DDR3L LRDIMM modules need replacement?

These 32 GB DDR3L 1600 CL11 modules are solid-state with no moving parts; they typically last the server's service life unless a voltage event or physical damage occurs.

What limits sustained throughput on these 1.35 V quad-rank LRDIMMs?

The DDR3L 1600 interface caps peak bandwidth at 12 800 MB/s per channel, so sustained workloads hit that bus ceiling before the 4Rx4 organisation becomes the bottleneck.

How much heat and power do four 32 GB 1.35 V LRDIMMs produce under continuous load?

Each module runs at 1.35 V low voltage, so the 128 GB kit draws modest power and generates less heat than standard 1.5 V DDR3, keeping cooling demands low in a populated server chassis.
