Server DDR5 ECC R-DIMM Kit

This V-color kit delivers 64 GB of DDR5 registered ECC memory across four 16 GB modules. It targets server and workstation platforms that require registered DIMMs for data-integrity workloads. The modules operate at 6400 MT/s with a CL52 latency profile. Desktop and laptop systems cannot use these registered modules.

Capacity and headroom at 6400 MT/s

Four ranks of 1Rx8 Hynix ICs provide 64 GB total capacity for multi-threaded server applications and virtualisation hosts. The CL52 timing and 1.1 V operation give stable throughput within the 0–85 °C operating range. Workloads that exceed 64 GB or demand lower latency than CL52 will need additional modules or a different specification.

Build quality and daily implications

A built-in thermal sensor monitors temperature to protect reliability during sustained loads. The registered design adds a clock cycle for signal integrity on densely populated motherboards. No heat spreader is fitted, so chassis airflow must handle module cooling directly. The 288-pin DDR5 form factor fits only compatible server and workstation boards.

Questions about this item

Will these 288-pin DDR5 6400MT/s CL52 ECC R-DIMMs run with older DDR5 server boards I still use?

These modules follow the DDR5 288-pin R-DIMM standard at 6400MT/s with CL52 timing, so they will function on any server or workstation motherboard that supports DDR5 ECC registered memory at that speed.

How can I confirm the 64GB kit is running at 6400MT/s with ECC active after installation?

Check the BIOS or UEFI memory information screen; it should report 6400MT/s (PC5-51200), CL52 timings, 1Rx8 rank, and ECC enabled for all four 16GB modules.

What is included in the box and what must I buy separately?

The package contains four 16GB DDR5 288-pin ECC R-DIMM modules with Hynix ICs; no heat spreaders, cables, or additional accessories are supplied.
