768GB DDR5 ECC RDIMM Kit

This 768GB kit contains twelve 64GB DDR5 4800 registered ECC modules built for Supermicro IOT SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR systems. It targets IT professionals who need maximum registered memory capacity in compatible Supermicro platforms.

12x 64GB 2Rx4 Registered Modules

The single specification that decides fit is the twelve-module 2Rx4 registered DDR5 4800 configuration with CL40 timing at 1.1V. Only motherboards that accept twelve 288-pin RDIMMs at this speed, rank and voltage will recognise the full 768GB capacity.

Fills Every Slot on Qualified Supermicro Boards

The kit occupies all twelve DIMM slots on the listed Supermicro IOT SuperServer models, leaving no room for additional memory. It requires a platform that supports 2Rx4 registered DDR5 at 4800 MT/s and 1.1V; systems limited to fewer slots, lower speeds or unbuffered memory cannot use this kit.

Questions about this item

Will 4800 MT/s DDR5 still run at that speed in a Supermicro SYS-221HE server?

The kit is validated for the Supermicro SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms, so it will operate at the rated 4800 MT/s in those systems.

Does the PC5-38400 rating limit the bandwidth I can expect from each 64 GB module?

PC5-38400 is the JEDEC designation for DDR5-4800; each module delivers the standard peak transfer rate defined by that specification.

Do the 288-pin RDIMM modules fit the memory slots in a Supermicro IOT SuperServer?

Yes, the 288-pin DDR5 RDIMM form factor matches the DIMM sockets on the supported Supermicro IOT SuperServer models.
