Server DDR5 64GB module

This 64GB DDR5 6400 PC5-51200 RDIMM delivers registered ECC memory for servers that require 2Rx4 organisation at 1.1V. It suits administrators upgrading compatible platforms with a single high-density module.

Registered ECC operation

The registered buffer and on-die ECC reduce electrical load on the memory controller and correct single-bit errors, improving data integrity for mission-critical workloads. These features replace standard unbuffered behaviour and require a server chipset that supports registered DIMMs.

Platform compatibility check

Verify that your server motherboard accepts DDR5 6400 registered RDIMMs with 2Rx4 density and 1.1V operation before ordering. This module is not compatible with desktop or workstation boards that only support unbuffered non-ECC memory.

Questions about this item

Will the 2Rx4 DDR5 6400 registered DIMM need firmware updates or battery-backed spares later?

No firmware updates or battery-backed components are required; the module is a standard registered ECC DIMM that remains in service until a hardware fault occurs.

Does the CL52 latency at 6400 MT/s become the bottleneck before thermal throttling on this 1.1 V module?

The CL52 timing is the fixed access latency; sustained throughput is limited by the 6400 MT/s data rate rather than thermal throttling at 1.1 V.

How much heat does the 64 GB registered DDR5 6400 DIMM produce when running continuously at 1.1 V?

At 1.1 V the module draws low power for its density, so heat output remains modest even under continuous server workloads.
