1TB DDR5-4800 ECC RDIMM kit

This 1 TB kit contains eight 128 GB DDR5 registered DIMMs running at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for Supermicro IoT SuperServer platforms including the SYS-211SE-31D, SYS-211SE-31A and X31SEED-F. ECC and 4Rx4 organisation provide error correction and high density for memory-intensive server workloads.

Suited for Supermicro DDR5 servers needing maximum

The kit targets administrators upgrading compatible Supermicro systems to the full 1 TB supported by eight DIMM slots. It is not for desktop PCs, laptops or workstations that accept only unbuffered UDIMMs. Buyers who need non-ECC memory, lower voltages, different form factors or smaller capacities should look at other memory lines.

Registered ECC with 4Rx4 organisation

Registered signalling and on-die ECC protect data integrity in mission-critical environments. The 4Rx4 rank structure delivers the highest module density available in the DDR5 RDIMM standard. Systems that require unbuffered memory or cannot address 4Rx4 modules will not support this kit.

Questions about this item

How much power does the 1TB DDR5 4800 kit draw at 1.10V under sustained load?

Each 128GB module runs at 1.10V, the standard DDR5 voltage, so the eight-module kit draws proportionally more power than smaller kits but stays within the DDR5 1.10V specification for registered DIMMs.

What must the SuperMicro server already have to accept this 8x128GB RDIMM kit?

The server needs 288-pin DDR5 RDIMM slots, support for 4Rx4 registered ECC modules, and a qualified memory configuration that allows 1TB total capacity across eight populated slots.

Will the CL40 4800 modules run stably in a SuperMicro 211SE that currently uses slower DDR5?

The kit is validated for SuperMicro 211SE, 31D, 31A and X31SEED-F systems; the motherboard will negotiate the highest common speed, so slower installed DDR5 simply causes all channels to operate at that lower rate.
