SAMSUNG 64GB DDR4 2400 LR-DIMM ECC 4Rx4 1.20V

Samsung 64 GB DDR4 LR-DIMM ECC module

This 64 GB DDR4 load-reduced DIMM delivers registered ECC memory for servers and workstations that require maximum capacity per slot. It operates at 2400 MHz with a 1.20 V supply and uses a 288-pin DDR4 interface. The module is built for data-intensive workloads in cloud and high-performance computing environments.

Sustained-load behaviour with load-reduced buffering

The load-reduced architecture replaces the standard register with a buffer chip, allowing four ranks in a 4Rx4 configuration without overloading the memory bus. This design maintains signal integrity during continuous, high-throughput operation typical of virtualisation hosts and database servers. ECC protection corrects single-bit errors in real time, preserving data accuracy under prolonged stress. The 1.20 V operating voltage helps limit thermal output during extended duty cycles.

Installation constraints and common pitfalls

The module fits 288-pin DDR4 slots wired for LR-DIMM support; it cannot be mixed with RDIMM, ECC UDIMM or standard UDIMM populations. System documentation must confirm LR-DIMM compatibility before purchase, as many platforms accept only registered DIMMs. Incorrect mixing prevents boot or forces the memory controller into a reduced-capacity mode. No special tools are required beyond standard DIMM ejection levers.
