  • Registered design reduces electrical load for stable operation
  • 1 V operation lowers power draw per gigabyte

64 GB DDR5 ECC RDIMM for servers

This 64 GB DDR5 4800 ECC RDIMM module is built for registered server and workstation platforms. It operates at 1.10 V with CL40 latency and a 2Rx4 rank layout on a 288-pin form factor.

Suited for ECC registered memory slots

It fits systems that require registered ECC DDR5 memory at 4800 MT/s. It will not work in consumer boards that only accept unbuffered non-ECC modules or earlier DDR generations.

Handles large memory arrays in multi-socket servers

The 64 GB capacity per module provides headroom for virtualisation, database and AI workloads. Systems limited to lower per-slot density or non-registered memory cannot use this module.

Questions about this item

Does my server motherboard need to support DDR5 ECC RDIMM at 4800 MT/s and 1.10 V for this 64 GB module to work?

Yes — the module is a 288-pin DDR5 RDIMM rated at 4800 MT/s (PC5-38400) with ECC and registered buffering at 1.10 V, so the platform must accept those exact specifications.

Can I keep my existing DDR5 4800 ECC RDIMMs and add this 2Rx4 64 GB stick without changing BIOS settings?

If the installed modules are also DDR5 4800 ECC RDIMMs at 1.10 V, the system will typically train at the common JEDEC speed and timings; mixed rank counts such as 2Rx4 are supported on most server chipsets.

How do I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information screen or use a tool such as dmidecode — it should report 4800 MT/s, CL40, 2Rx4 organisation and ECC type as multi-bit error-correcting.
