Server Memory Kit for Supermicro CloudDC

This 1TB kit contains sixteen 64GB DDR5 4800 RDIMM modules built for Supermicro CloudDC SuperServer systems. Registered ECC design with 2Rx4 organisation targets enterprise workloads that demand data integrity and high density. Operates at 1.1V with CL40 latency for stable server operation.

Verify DIMM Slots and Population Rules

Confirm your Supermicro SYS-621C-TN12R SYS-611C-TN4R or SYS-121C-TN2R chassis has sixteen available 288-pin DDR5 RDIMM slots before ordering. Check the motherboard manual for supported population sequences and maximum capacity per channel. Ensure the platform BIOS revision recognises 64GB 2Rx4 registered modules at 4800MT/s.

Registered ECC Modules Without Heat Spreaders

Bare green PCBs expose the major OEM Samsung Micron Hynix DRAM for direct airflow cooling in dense server chassis. 288-pin RDIMM form factor locks securely into standard DDR5 server sockets. Registered buffering reduces electrical load on the memory controller enabling full sixteen-module population. ECC circuitry corrects single-bit errors during continuous operation.

Questions about this item

Does the MR38400-924K16 kit include all 16 DDR5 64GB RDIMM modules or must any be purchased separately?

The package contains the full 1TB kit — 16 modules of 64GB each — so nothing else is needed to reach the stated capacity.

Should I choose the 2Rx4 CL40 4800 MT/s version or is another rank or latency offered for these Supermicro servers?

This kit is only available as 2Rx4 CL40 at 4800 MT/s; no alternative rank or latency options are listed for the compatible SYS-121C-TN2R, SYS-611C-TN4R or SYS-621C-TN12R systems.

What does the PC5-38400 rating mean once the memory is installed in a Supermicro CloudDC SuperServer?

PC5-38400 confirms the modules run at DDR5 4800 with a 1.10V operating voltage and CL40 latency, delivering the rated bandwidth when populated in the server's 288-pin RDIMM slots.
