384GB DDR5 RDIMM kit for Supermicro H14DST-F

This 384GB kit contains eight 48GB DDR5 4800 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DST-F memory controller expects. It targets administrators who need maximum capacity per channel without mixing ranks or speeds.

Registered ECC design for full-slot population

The 2Rx8 registered architecture offloads the memory controller so every 288-pin slot can run fully populated at 4800 MT/s while ECC corrects single-bit errors on the fly. No heat spreaders are included; airflow must be managed by the server chassis.

Lifetime replacement and US-based support

The kit ships as a matched set of eight modules under a lifetime replacement warranty with free US-based technical support. Buyers who need a different capacity, mixed-rank configuration or UDIMM form factor should look elsewhere.

Questions about this item

What maximum capacity does the Supermicro H14DST-F support with a fully populated eight-module kit of 48 GB DDR5 RDIMMs?

The kit provides 384 GB using eight 48 GB modules, matching the motherboard's supported configuration for full-capacity operation.

How does the registered ECC design affect thermal and power behaviour under continuous load?

Registered architecture buffers the command bus, reducing electrical load on the memory controller, while ECC corrects single-bit errors, maintaining stability during sustained server workloads.

What motherboard slot type and population rules must the H14DST-F already have for this 288-pin RDIMM kit to function?

The board must provide 288-pin DDR5 RDIMM slots and follow its documented population order for eight 2Rx8 modules at 4800 MT/s and 1.1 V.
