System-specific DDR5 server memory kit

This 1 TB kit contains sixteen 64 GB DDR5 4800 RDIMM modules built for Supermicro IOT SuperServer models SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR. It targets administrators who need maximum registered ECC capacity in those qualified platforms.

Sustained-load behaviour with registered ECC

Registered buffering and on-die ECC maintain signal integrity and data correctness during continuous heavy workloads across all sixteen slots. The 1.1 V operating voltage keeps power draw predictable while the modules run at the rated 4800 MT/s speed.

Capacity and form factor decide fit

The kit delivers exactly 1 TB in a 16 x 64 GB configuration using 288-pin DDR5 RDIMM modules with 2Rx4 organisation. Systems that cannot accept sixteen registered DIMMs or that require a different rank structure cannot use this kit.

Questions about this item

How much power does the 1.10 V DDR5 4800 kit draw when the server runs continuously?

Each 64 GB module operates at 1.10 V DDR5 standard voltage; total draw depends on how many of the sixteen sticks are populated and the workload, so consult the platform's power budget for exact figures.

What must the motherboard provide for these 288-pin registered ECC modules to function?

The board needs DDR5 RDIMM slots, registered ECC support, and a qualified memory controller that accepts 2Rx4 organization at 4800 MT/s.

Can the 2Rx4 CL40 registered DDR5 sticks share channels with older DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds on the same channel is not recommended; the memory controller will down-clock all modules to the slowest common timing and may require specific population rules.
