Exact-match DDR5-4800 ECC RDIMM kit

This 512GB kit contains 16 modules of 32GB each, built to the DDR5 4800 (PC5-38400) standard with CL40 timing and 1.1V operation. It is designed for the Supermicro H14SST-G motherboard and uses 288-pin registered DIMMs with 2Rx8 organization. Enterprise workloads that demand registered ECC memory at full population will find the correct form factor and electrical spec here.

Capacity and headroom

Sixteen slots filled with 32GB RDIMMs deliver 512GB of registered ECC memory, the maximum density this board supports when every DIMM slot is populated. The registered architecture buffers address and command signals so the memory controller remains stable across all 16 slots at the rated 4800 MT/s speed. Workloads that exceed 512GB or require speeds above DDR5-4800 will need a different platform.

Upgrade path and fitment

This kit replaces any smaller-capacity DDR5 RDIMM set or mixed-rank configuration that cannot reach full 512GB capacity on the H14SST-G. The jump is worth it when your application needs every slot populated with matched 2Rx8 modules at 1.1V to avoid down-clocking or population-rule conflicts. Buyers who need UDIMM, SODIMM, or non-ECC memory cannot use this product.

Questions about this item

Will the 16 DIMMs in this 512GB DDR5 4800 CL40 kit work alongside any existing RDIMMs I keep in my Supermicro H14SST-G?

The kit uses 2Rx8 registered ECC modules at 1.1V; your motherboard manual defines which slots can mix ranks and capacities, so follow its population rules exactly.

How do I verify the kit is running at DDR5 4800 with ECC active after installation?

Boot into the BIOS and check that the memory speed shows 4800 MT/s, total capacity reads 512GB, and ECC is reported as enabled.

What ships in the box and what must I source separately for the Supermicro H14SST-G?

The box contains the 16 x 32GB DDR5 4800 CL40 2Rx8 1.1V 288-pin ECC RDIMMs; no cables, brackets or additional hardware are included.
