Purpose-built server memory kit

This 768GB kit delivers 12 matched 64GB DDR5 4800 RDIMM modules for SuperMicro CloudDC SuperServer platforms. It targets administrators who need maximum registered ECC capacity in validated configurations. The modules operate at 1.1V with CL40 latency and 2Rx4 organisation.

Registered ECC RDIMM with 2Rx4 layout

The single specification that determines fit is the registered ECC RDIMM form factor with 2Rx4 rank architecture. Only motherboards that explicitly support DDR5 registered DIMMs at this rank structure will initialise the kit. Unbuffered or consumer UDIMM slots cannot use these modules.

768GB total across twelve slots

Twelve 64GB modules fill every DIMM slot on compatible dual-socket SuperMicro SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R systems. Capacity headroom suits large-scale virtualisation, in-memory databases and HPC workloads. Systems with fewer than twelve slots or lower per-slot limits cannot accept the full kit.

Questions about this item

What does the 4800 MT/s rating mean once these modules are installed in a SuperMicro server?

The kit runs at the standard DDR5 4800 MT/s JEDEC speed, delivering PC5-38400 bandwidth per module when the server memory controller is set to its default profile.

How does the 288-pin DDR5 RDIMM interface limit the maximum speed in this configuration?

The registered 288-pin DDR5 form factor locks the kit to the 4800 MT/s JEDEC baseline; higher frequencies would require a motherboard and CPU that support overclocked memory profiles.

What physical space and slot layout are needed to fit all twelve 64 GB modules?

Twelve 288-pin RDIMM slots are required, which matches the memory capacity of the listed SuperMicro CloudDC SuperServer models SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R.
