Supermicro MEM-DR564L-SL01-ER48 64GB DDR5 4800 ECC Registered server RAM

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.
