Server DDR5 RDIMM kit

This V-color kit delivers 64 GB of DDR5 registered ECC memory in two 32 GB modules. It is built for server and workstation motherboards that require RDIMM topology and will not function in standard desktop or laptop systems.

Hynix IC and thermal sensor

High-quality SK Hynix ICs are auto-sorted during production and each module includes an on-board temperature sensor. These features work together to maintain data integrity and prevent overheating under sustained server workloads.

64 GB capacity at CL52

The dual-rank modules run at 6400 MT/s with CL52 timings and a low 1.1 V operating voltage, providing ample bandwidth for virtualisation and database tasks. Systems needing more than 64 GB or higher frequencies will require additional kits or faster-rated memory.

Questions about this item

Does the lack of a heat spreader on the V-color DDR5 64GB kit mean I will need to add active cooling later?

The modules have no heat spreader and rely on chassis airflow; they include a built-in thermal sensor to monitor temperature up to the 85 °C operating limit.

What is the first limit reached under sustained load with these CL52 6400 MT/s modules?

The rated speed is DDR5-6400 with 52-52-52-103 timings at 1.1 V; sustained operation stays within the 0–85 °C range monitored by the on-module sensor.

How much power and heat does the 2x32GB registered kit draw when running all day in a server?

Each DIMM operates at 1.1 V with SK Hynix ICs in a 2Rx8 configuration; the integrated thermal sensor tracks temperature to prevent overheating during continuous use.
