Server memory for DDR4 LRDIMM platforms

This 32 GB DDR4 2133 ECC Load Reduced DIMM is built for servers and workstations that require registered, high-density modules. It operates at 1.20 V and uses a 288-pin form factor with a 4Rx4 quad-rank organisation. Desktop and laptop systems cannot accept this module.

LRDIMM slots and memory-controller limits

Load Reduced DIMMs reduce electrical load on the memory bus, allowing more modules per channel than standard registered DIMMs. The platform must explicitly support DDR4 LRDIMM technology and quad-rank x4 addressing; standard RDIMM-only controllers will not initialise these modules. Maximum capacity and population rules are defined by the system firmware.

4Rx4 quad-rank density

The 4Rx4 organisation delivers 32 GB in a single module, which suits configurations that need high capacity per slot. Systems limited to dual-rank or single-rank DIMMs will not recognise the full density. Verify the motherboard qualified-vendor list for 4Rx4 LRDIMM support before purchasing.

Questions about this item

Should I choose this single 32GB module or look for a kit with multiple sticks?

This is a single 32GB module. Add multiple identical modules to fill your server's memory channels according to the system manual for optimal performance.

What real-world throughput does the PC4-17000 rating deliver in a server?

The module runs at 2133 MT/s, providing up to 17000 MB/s theoretical peak bandwidth per module; actual throughput depends on your platform's memory controller and channel configuration.

How does the Load Reduced DDR4 interface affect maximum capacity per channel?

The LRDIMM buffer reduces electrical load on the memory bus, allowing more ranks per channel so servers can support higher total memory capacities than with standard RDIMMs.
