64GB DDR4 LRDIMM for servers

This Samsung module provides 64GB of DDR4 memory in a 288-pin load-reduced DIMM. It runs at 2400 MHz with a PC4 19200 data rate. The part is new and intended for server platforms that accept LRDIMM modules.

Who this suits and who it does not

It fits administrators expanding memory in systems qualified for DDR4 LRDIMM at 2400 MHz. Builders whose platforms require registered DIMMs, unbuffered DIMMs or a different DDR generation cannot use this module. Systems limited to lower per-slot capacities should also select a different part.

Deciding specification: Load Reduced DDR4 2400

The module is a Load Reduced DDR4 2400 part. That classification determines whether the memory controller and motherboard slot can support it. Verify the platform documentation for LRDIMM compatibility at this speed before purchase.

Questions about this item

Will the 288-pin DDR4 LRDIMM modules need periodic replacement under normal server operation?

No, the 64 GB DDR4 2400 LRDIMM modules are solid-state with no moving parts and do not require scheduled replacement under normal server operation.

What limits sustained throughput on the PC4-19200 interface during continuous workloads?

The DDR4 2400 bus speed and PC4-19200 data rate set the maximum sustained bandwidth the module can deliver.

How much heat and power does the 64 GB load-reduced DIMM produce when running all day?

The load-reduced design lowers electrical load on the memory bus, reducing power draw and heat output compared with standard registered DIMMs at the same 2400 MHz speed.
