Server memory upgrade

This 32GB DDR4 module is built for servers that require ECC Load Reduced DIMMs. It targets administrators who need to expand memory capacity in qualified Supermicro platforms.

Quad-rank LRDIMM form factor

The module uses a 4Rx4 organisation on a 288-pin LRDIMM, which is the single specification that determines whether the part fits the memory slot and is recognised by the system BIOS.

32GB capacity at 2133MHz

The single stick delivers 32GB of registered ECC memory running at 2133MHz CL15. It handles large virtualisation workloads and database buffers, while total system capacity remains limited by the number of available DIMM slots.

Questions about this item

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

The PC4-17000 rating corresponds to a peak transfer rate of 17 GB/s at 2133 MHz, so sustained throughput in a server will be somewhat lower depending on the memory controller and workload.

How does the LRDIMM interface affect maximum memory capacity per channel?

Load Reduced DIMMs buffer the data and address lines, letting the memory controller drive more ranks per channel than standard RDIMMs and enabling higher total capacity configurations.

Will this 288-pin LRDIMM fit in a standard DDR4 server DIMM slot?

Yes, the module uses the standard 288-pin DDR4 LRDIMM form factor, so it installs in any compatible server DIMM slot that supports Load Reduced memory.
