32GB DDR4-2400 LRDIMM for dense server memory

This Samsung module delivers 32GB of DDR4-2400 capacity in a load-reduced DIMM format. It targets servers and workstations that require high memory density per slot while maintaining error-correcting code protection. The 288-pin form factor fits standard DDR4 server platforms.

Upgrading from standard RDIMM to LRDIMM

Load-reduced DIMMs reduce electrical load on the memory bus, allowing more modules per channel than registered DIMMs at the same speed. The jump is worth it when the platform supports LRDIMM and the configuration demands maximum capacity per channel beyond what registered ranks can provide.

Practical limits of DDR4-2400 LRDIMM

The DDR4-2400 interface caps bandwidth at PC4-19200 per module, and the 1.20V voltage is fixed for this generation. Total system capacity and channel population are ultimately constrained by the memory controller and BIOS, not by the module alone. Mixed-rank or mixed-speed configurations may force lower operating frequencies.

Questions about this item

Does the 288-pin DDR4 form factor fit standard server DIMM slots?

Yes, the 288-pin DDR4 SDRAM module fits standard DDR4 DIMM slots on server motherboards.

What is the correct way to seat this load-reduced DIMM, and what step is often missed?

Align the notch with the slot key, press down firmly until both side latches click, and ensure the 1.20V module is fully seated before powering on.

When should the 32GB 2Rx4 LRDIMM be replaced in a production server?

Replace the module if the system logs show persistent correctable ECC errors, uncorrectable errors, or if memory diagnostics report failures on this 32GB stick.
