384GB DDR5 ECC RDIMM Kit for Supermicro H14DSG-OM

This 384GB kit contains six 64GB DDR5 4800 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. It is for administrators who need the full 384GB capacity recognised at rated speed without manual tuning. Buyers whose platforms require UDIMM, SODIMM or non-ECC memory cannot use this kit.

Sustained Enterprise Stability

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity under continuous load. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads. The 1.1V operating voltage and CL40 timing are maintained across all six modules without throttling.

2Rx4 Registered ECC at 1.1V DDR5 4800

The single specification that decides fitment is the 2Rx4 Registered ECC organisation at 1.1V DDR5 4800 with CL40 latency in a 288-pin RDIMM form factor. Your motherboard manual must confirm support for this exact rank structure, voltage and population rule before purchase.

Questions about this item

How much power do six 64 GB DDR5 4800 RDIMMs draw when the Supermicro H14DSG-OM runs continuously?

Each module operates at 1.10 V and the DDR5 standard moves power management onto the DIMM itself, so total draw scales with the 384 GB capacity you populate rather than a fixed board limit.

What motherboard slot type and population rules must the Supermicro H14DSG-OM already have to accept this 6 x 64 GB kit?

The board needs 288-pin DDR5 RDIMM slots and must support 2Rx4 registered ECC modules at 4800 MT/s; consult the manual for the exact population order required for all six slots.

Will the registered ECC design of these DDR5 4800 CL40 modules keep the server stable if I fill every slot on the H14DSG-OM?

Yes — the registered architecture buffers address and command signals so the memory controller can drive all six 64 GB 2Rx4 DIMMs at the rated 4800 MT/s, while on-die ECC corrects single-bit errors in real time.
