64GB LRDIMM for Cisco Servers

This 64GB DDR4-2400 load-reduced module uses a 4Rx4 organisation and ECC to maximise capacity in compatible Cisco platforms. It runs at PC4-19200 with CL15 latency and a standard 1.20V supply. The 288-pin form factor matches the OEM UCS-ML-1X644RV-A specification for direct replacement.

Thermals Power and Noise

As a passive memory module it adds no fan noise and draws minimal power at the rated 1.20V. Heat is dissipated through the PCB and the server's existing airflow design. The load-reduced buffer reduces electrical loading on the memory bus, helping the platform maintain stability under full population.

Build Fit and Freed Slots

Each module delivers 64GB in a single 288-pin slot, letting administrators reach higher total memory with fewer occupied sockets. Major-brand DRAM from Samsung, SK Hynix or Micron ensures the same electrical characteristics as Cisco-branded units. The module is guaranteed compatible with systems requiring this exact DDR4-2400 LRDIMM specification.

Questions about this item

How do I install the 288-pin DDR4 LRDIMM and what step do people get wrong?

Align the single notch on the 288-pin edge connector with the slot key, press straight down until both retention clips click, and verify the module height clears the CPU cooler; the common error is seating only one side, which leaves the ECC link uninitialised.

What maintenance or replacement will the 64GB 4Rx4 LRDIMM need later?

No scheduled maintenance is required; if a correctable ECC error count rises above the platform threshold the module should be replaced, otherwise it runs for the server's service life.

What limit appears first on the 1.20V DDR4-2400 LRDIMM under sustained load?

The thermal envelope of the load-reduced buffer chip is the first constraint; once the case temperature exceeds the JEDEC limit the memory controller throttles bandwidth to protect data integrity.
