512GB DDR5 ECC RDIMM kit for Supermicro

This 512GB kit contains 16 DDR5-4800 RDIMMs of 32GB each. The modules are Registered ECC with 2Rx8 organisation, CL40 timing and 1.10V operation. They are built for the Supermicro H13DSG-O-CPU-D motherboard and its 288-pin RDIMM slots.

Exact-match specification prevents population errors

The kit matches the board's required rank, voltage and timing so every slot is recognised at full capacity and rated speed. Registered buffering offloads the memory controller for stable fully-populated operation while ECC corrects single-bit errors before they affect production workloads.

Installation follows the motherboard manual sequence

The 288-pin RDIMMs seat in the board's DDR5 slots using the population order documented by Supermicro. Common issues arise when DIMMs are inserted in the wrong sequence or when the manual's maximum-capacity rules are overlooked, so verify the approved configuration before fitting all 16 modules.

Questions about this item

Will the 16 DIMMs need any active cooling or periodic replacement in a server running continuously?

The modules have no heat spreader and run at 1.1V; registered ECC DDR5 RDIMMs are rated for continuous server duty and do not require scheduled replacement.

What limit appears first when all 16 slots of the Supermicro H13DSG-O-CPU-D are populated at DDR5-4800?

The memory controller drops to the JEDEC standard 4800 MT/s with 2Rx8 registered DIMMs in every slot, so bandwidth per core becomes the bottleneck before voltage or thermal limits.

How much extra power and noise do the 512GB of 1.1V registered ECC DDR5 add in a fully populated chassis running all day?

At 1.1V each 32GB 2Rx8 RDIMM draws only a few watts, so the kit adds minimal heat and no audible noise beyond the existing system fans.
