128GB DDR4 2400 ECC LRDIMM Module

This 128GB DDR4 2400 ECC LRDIMM module is built for servers and workstations that require high-density registered memory. It operates at PC4-19200 speed with a CAS latency of 17 and runs at the standard 1.20V voltage. The load-reduced design helps reduce electrical load on the memory controller in multi-module configurations.

Who This Suits and Who Should Look Elsewhere

This module suits administrators upgrading HP systems referencing part numbers 819415-001, 809086-091 or 809208-B21 where a single 128GB LRDIMM is qualified. It is not for desktop PCs or laptops that only accept unbuffered UDIMMs or SODIMMs. Buyers who need non-ECC memory or standard registered DIMMs instead of load-reduced modules should look elsewhere.

288-Pin DDR4 DIMM Form Factor

The module uses the 288-pin DDR4 DIMM form factor required by compatible server motherboards. Verify that your system board supports DDR4 LRDIMM technology and 128GB density per slot before purchase. The 2S4Rx4 (8Rx4) 3DS/TSV rank structure must match the platform memory population rules.

Questions about this item

How much power does the 128GB DDR4 2400 LRDIMM draw at its rated 1.20V?

The module operates at the standard DDR4 voltage of 1.20V. As a Load Reduced DIMM, it reduces electrical load on the memory bus, which helps manage overall system power draw in dense configurations.

What motherboard slot and CPU memory controller are required for this 288-pin DDR4 ECC LRDIMM?

This module requires a server or workstation motherboard with DDR4 288-pin DIMM slots and a CPU memory controller that supports ECC Load Reduced DIMMs at 2400MHz.

Can this 8Rx4 3DS/TSV LRDIMM run alongside existing RDIMMs in the same HP server?

No. Load Reduced DIMMs use a different buffering architecture than standard RDIMMs. Mixing LRDIMMs with RDIMMs is not supported and will prevent the system from booting.
