Server-grade DDR4 LRDIMM kit

This 64 GB kit consists of two 32 GB DDR4 2133 MHz CL15 modules built to the PC4-17000 standard. Each stick is a 288-pin ECC load-reduced DIMM operating at 1.2 V with a 4Rx4 rank structure. The modules are designed for servers, workstations and NAS systems that specifically require registered load-reduced memory.

Load-reduced ECC constraint

Load-reduced DIMMs reduce electrical load on the memory bus so higher capacities can be installed per channel, but they only work in platforms whose chipset and BIOS explicitly support LRDIMM technology. The memory cannot be mixed with unbuffered or standard registered DIMMs, and it will not function in consumer desktop or laptop boards that lack ECC LRDIMM support.

Verify platform compatibility

Before ordering, confirm that your motherboard or system documentation lists DDR4 2133 MHz ECC load-reduced DIMMs in a 288-pin 4Rx4 configuration as supported. Check the qualified vendor list for the exact part number and ensure the firmware revision recognises the modules at the rated speed and latency.

Questions sur cet article

Should I choose the dual-channel kit or buy single modules to reach 64 GB?

The kit already provides 64 GB as two matched 32 GB modules, so the dual-channel configuration is ready to install without mixing separate sticks.

What does the 2133 MHz rating deliver in a live server?

The modules run at DDR4 2133 with CL15 latency, giving a PC4-17000 peak transfer rate for workloads that benefit from ECC error correction and load-reduced signalling.

How does the LRDIMM interface affect maximum capacity per channel?

Load-reduced DIMMs buffer the command and address bus, allowing the 4Rx4 organisation to place 32 GB on each 288-pin module without exceeding the memory controller's electrical load limits.
