64GB DDR5 4800MHz ECC RDIMM

This is a 64GB DDR5 4800MHz ECC registered DIMM built with Samsung chips and validated for Supermicro platforms. It operates at 1.10V with a CAS latency of CL40 in a 2Rx4 dual-rank configuration. The module uses the standard 288-pin form factor for DDR5 server memory.

Suited for Supermicro servers needing certified

This module suits administrators expanding memory in Supermicro systems that require vendor-certified DDR5 4800 RDIMMs with native ECC. It is not for desktops or workstations that accept only unbuffered UDIMMs. Buyers who need lower voltages, different latencies, or non-ECC memory should look elsewhere.

Supermicro certification decides fit

The single specification that determines compatibility is the Supermicro certification MEM-DR564L-SL01-ER48 matching the system qualified vendor list. Only platforms listing this exact part number guarantee supported operation. Always verify the QVL before purchase.

Questions about this item

Will the Samsung M321R8GA0BB0-CQK chips on this 64GB DDR5 4800MHz module need replacement under heavy server loads?

The Samsung M321R8GA0BB0-CQK chips are tested for dependable performance and carry a lifetime warranty, so replacement is not expected under normal sustained server workloads.

At CL40 latency and 1.10V, what limit appears first when this 2Rx4 RDIMM runs continuously at 4800MHz?

The CL40 timing at 1.10V is the DDR5 JEDEC standard for 4800MHz operation; the module runs within its rated electrical and thermal envelope during continuous use.

How much heat and power does a single 288-pin 64GB DDR5 4800MHz ECC RDIMM produce when running all day?

At the standard 1.10V DDR5 voltage, power draw and heat output stay within the JEDEC specification for a 4800MHz registered DIMM, and the module includes on-die ECC for data integrity.
