  • 288GB capacity from six 48GB modules for maximum server density
  • Registered ECC RDIMM design prevents data corruption in critical workloads
  • DDR5-4800 CL40 at 1.1V matches Supermicro H14DSH memory controller specs
  • 2Rx8 dual-rank organisation enables full-population stability across all slots
  • Lifetime replacement warranty with US-based technical support included

Supermicro H14DSH exact-match kit

This 288 GB DDR5 kit ships as six 48 GB Registered ECC RDIMMs built to the Supermicro H14DSH motherboard specifications. It targets administrators who need the full 288 GB capacity recognised at rated speed without manual tuning.

Registered ECC stability at full population

Registered buffering offloads the memory controller so all slots run fully populated at DDR5 4800 CL40 1.10 V. On-die ECC corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

288 GB headroom for dense virtualization

Six 48 GB dual-rank modules deliver the maximum capacity this board accepts per the supplier data, supporting heavy container densities and large in-memory databases. Workloads that exceed 288 GB or require faster than 4800 MT/s will need a different platform.

Questions about this item

Will the RDIMM modules need any firmware updates or periodic reseating to maintain stability in the Supermicro H14DSH?

No firmware updates are required; the kit is an exact-match DDR5-4800 CL40 2Rx8 registered ECC set that the memory controller recognises at full 288 GB capacity without further intervention.

What is the first limit reached when all six slots run continuously at DDR5-4800?

The memory controller's maximum supported speed of DDR5-4800 (PC5-38400) is the ceiling; the modules already operate at that rated frequency and 1.10 V, so no higher data rate is possible.

How much heat does the kit add to the chassis when the server runs all day?

Each 48 GB module runs at 1.10 V with no heat spreader, so thermal output is limited to the low-voltage registered ECC design; system fans handle the load without extra cooling.
