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.

Questions about this item
How much heat does the 1.20V DDR4 LR-DIMM add when running 24/7?
The module operates at 1.20V, the standard DDR4 voltage, so it adds typical server-memory heat without extra power draw beyond the rated PC4-19200 speed.
What motherboard slot and memory-type support must my system already have for this 288-pin module?
You need a DDR4 LR-DIMM compatible 288-pin slot; RDIMM, UDIMM or other memory types cannot be mixed with this Load Reduced design.
Can I keep my existing 2400MHz RDIMMs and add this 64GB 4Rx4 LR-DIMM?
No, LR-DIMM cannot be mixed with RDIMM or any other memory type — the system must use LR-DIMM exclusively.
