64 GB DDR5 RDIMM for servers

This single 64 GB module delivers DDR5 4800 registered ECC memory for enterprise servers and workstations. It operates at the standard 1.1 V DDR5 voltage with CL40 latency and a dual-rank x4 organisation. The 288-pin form factor fits only platforms built for DDR5 RDIMM modules.

Suits ECC registered platforms only

Systems that require registered ECC DDR5 memory will accept this module; desktops, laptops and any board limited to unbuffered or non-ECC DIMMs cannot use it. Buyers needing unbuffered memory or a different capacity must select another part.

Registered ECC with dual-rank x4 layout

The RDIMM register and on-die ECC combine with a 2Rx4 chip arrangement to provide the error correction and signal integrity that server chipsets expect. This specification is the deciding factor for compatibility.

Questions about this item

Does my server motherboard need to support DDR5 ECC Registered RDIMM at 4800 MHz for this 64GB module to work?

Yes, the module is a DDR5 4800 PC5-38400 EC8 RDIMM with 2Rx4 organisation and 1.10 V operation, so the platform must explicitly support DDR5 ECC Registered memory at that speed and voltage.

Can I mix this 4800 MHz CL40 DDR5 RDIMM with slower DDR5 ECC Registered modules already installed in my workstation?

The system will run all installed DDR5 ECC Registered DIMMs at the lowest common speed and highest common latency, so this CL40 4800 MHz module will down-clock to match any slower modules present.

How can I confirm the module is running at 4800 MHz with ECC active after installation?

Check the BIOS memory information screen or use an OS tool such as dmidecode or CPU-Z to verify the reported speed shows 4800 MT/s, the type shows DDR5 ECC Registered, and the voltage reads 1.1 V.
