64GB DDR5 4800 RDIMM for servers

This registered ECC module delivers 64GB of DDR5 4800 memory with CL40 latency. It is built for enterprise servers and workstations that require error correction and signal buffering. The dual-rank 2Rx4 organisation uses Samsung components and operates at 1.10V. It suits administrators who need maximum capacity per slot in compatible DDR5 platforms.

Thermals and power at standard speed

At the rated DDR5 4800 frequency the module runs at 1.10V, keeping power draw low for a 64GB stick. Registered buffering reduces electrical load on the memory controller, which helps system thermals in densely populated chassis. No active cooling is required on the module itself; airflow from standard server fans is sufficient. Quiet operation is maintained because the DIMM has no moving parts.

Behaviour under sustained load

Error correction and registered signalling preserve data integrity during continuous workloads such as virtualisation, databases or high-performance computing. The CL40 timing remains stable at the specified voltage during extended operation. Capacity and bandwidth scale linearly when multiple modules populate the memory channels. Systems that do not support DDR5 RDIMM or registered ECC cannot use this module.

Questions about this item

How do I install this 64GB RDIMM in my server?

Power down the server, open the chassis, align the module notch with the DDR5 slot key, press firmly until both retention clips lock, then verify 4800 MT/s speed in BIOS.

What maintenance or replacement will this Samsung 2Rx4 module need later?

No routine maintenance is required; ECC corrects single-bit errors on the fly, and the module should only be replaced if the server logs report uncorrectable errors.

What limit appears first under sustained load on this CL40 1.10V DDR5 stick?

The JEDEC DDR5 thermal envelope is reached first; prolonged heavy traffic raises case temperature until the module throttles to protect data integrity.
