512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. Modules operate at 1.1V and use a 288-pin 4Rx4 organisation built from major OEM DRAM. The kit is validated for SuperMicro IoT SuperServer platforms including the SYS-211SE-31D and SYS-211SE-31A.

Suited for SuperMicro servers needing maximum

Administrators expanding memory in compatible SuperMicro IoT SuperServer systems will meet the platform requirements. Builds that require unbuffered UDIMMs, non-ECC memory, lower voltages or consumer desktop platforms cannot use these registered modules.

Registered 4Rx4 organisation at 1.1V decides fit

The 4Rx4 registered layout and 1.1V operating voltage are fixed by the module design and must match the motherboard memory controller specification. If the target system expects a different rank configuration or voltage this kit will not function.

Questions about this item

How much power does each 128GB DDR5 4800 CL40 1.1V ECC RDIMM module draw under sustained load?

Each module operates at 1.10V; total kit capacity is 512GB across four 128GB RDIMMs.

What motherboard slot and chipset combination is required to run this 288-pin DDR5 RDIMM kit at 4800 MT/s?

The kit uses 288-pin DDR5 RDIMM form factor and is validated for SuperMicro IoT SuperServer SYS-211SE-31D, SYS-211SE-31A and X31SEED-F MBD platforms.

Will this 4Rx4 registered ECC memory work alongside existing 2Rx8 DDR5 RDIMMs in the same SuperMicro server?

The kit is a matched 4 x 128GB 4Rx4 set; mixing ranks is not recommended and may prevent the system from posting.
