Capacity and form factor

This is a single 64GB DDR4 LRDIMM built for server and workstation platforms that require load-reduced registered memory. The module uses a 288-pin DIMM form factor and operates at the standard DDR4 voltage of 1.2V. It is intended for administrators upgrading compatible Micron-referenced systems.

Sustained-load behaviour

The module runs at DDR4 2400 with a CAS latency of CL17 and a 4Rx4 rank structure. Load-reduced buffering lowers the electrical load on the memory controller, helping maintain stability when all slots are populated under continuous multi-threaded workloads. ECC protection corrects single-bit errors to preserve data integrity during extended operation.

Compatibility checks

Verify that your system board and processor support DDR4 LRDIMM modules with a 4Rx4 organisation before ordering. Confirm the maximum supported capacity per slot and the qualified memory list for your specific server model. Mixing LRDIMMs with standard RDIMMs is not supported on most platforms.

Questions about this item

How much heat and power does the 64GB DDR4 2400MHz LRDIMM draw when running continuously at 1.20V?

The module operates at the standard DDR4 voltage of 1.20V and uses Load Reduced technology to lower electrical load on the memory bus, which helps limit heat output and power draw during sustained server workloads.

What motherboard slot and chipset support are required to install this 288-pin DDR4 LRDIMM?

This memory requires a server or workstation motherboard with 288-pin DDR4 DIMM slots that support ECC Load Reduced DIMMs at 2400MHz; the board must also accept 4Rx4 modules and provide the 1.20V DDR4 standard voltage.

Will this CL17 4Rx4 LRDIMM work in a system that currently uses older DDR4 ECC RDIMMs?

Load Reduced DIMMs use a different buffering architecture than standard Registered DIMMs, so they cannot be mixed with RDIMMs in the same memory channel; the platform must support LRDIMMs specifically for this module to function.
