64GB DDR5 6400 ECC RDIMM

This 64GB DDR5 6400 MHz ECC Registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1.1V with a dual-rank x4 organisation on a 288-pin form factor. The module is not compatible with desktop or laptop computers.

Single-module upgrade for registered memory systems

The single 64GB module adds capacity to registered DDR5 channels without requiring a matched kit. ECC Registered operation corrects single-bit errors and detects multi-bit errors to protect data integrity in critical workloads. Major-brand chips and rigorous testing aim to deliver dependable performance in qualified platforms.

Suited for qualified DDR5 servers and workstations

This module suits administrators expanding memory in systems validated for 64GB DDR5 6400 ECC RDIMMs. Builders needing unbuffered memory, non-ECC modules, desktop SO-DIMMs, or speeds other than 6400 MHz should look at something else.

Questions about this item

Will the 2Rx4 dual-rank organisation require any firmware or BIOS updates when I add more modules later?

The module is a 2Rx4 DDR5 RDIMM running at 1.10 V; most server platforms accept additional dual-rank modules without a firmware change, but you should check the system manual for population rules and maximum rank limits.

What thermal limit appears first when the DIMM runs continuously at 6400 MHz?

Without a heat spreader the DRAM temperature will reach its throttling point before the 1.10 V power envelope becomes an issue, so sustained loads depend on chassis airflow over the bare chips.

How much power does a single 64 GB stick draw at full 6400 MHz speed all day?

At the standard DDR5 voltage of 1.10 V the module draws roughly 11 W under continuous maximum bandwidth, so total power scales linearly with the number of populated slots.
