384GB DDR5 ECC RDIMM kit for Supermicro H14DSG-OD

This 12-module kit delivers 384GB of DDR5 4800 registered ECC memory in matched 32GB 2Rx8 DIMMs. It is built for the Supermicro H14DSG-OD motherboard where full-slot population and registered architecture are required for stable operation.

Registered ECC architecture with 2Rx8 organisation

The registered buffer reduces electrical load on the memory controller so all twelve slots can run at the rated 4800 MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption in production workloads.

DDR5 4800 CL40 at 1.10V 288-pin RDIMM

The modules operate at the standard DDR5-4800 (PC5-38400) speed with CL40 latency at 1.10 volts. This exact voltage, timing and pin-out combination is what the H14DSG-OD memory controller expects for full-capacity recognition. Builders needing UDIMM, SODIMM or a different voltage must choose another kit.

Perguntas sobre este artigo

Will the 12-module 384GB kit need any firmware updates or battery-backed spares over its service life?

DDR5 RDIMMs have no onboard battery or field-updatable firmware; the only maintenance is reseating modules if the server reports correctable ECC errors after years of vibration.

What caps sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s transfer ceiling is reached before CL40 latency becomes the bottleneck, so sustained bandwidth tops out at the rated PC5-38400 line speed.

How much extra heat and power do the twelve 1.10 V registered DIMMs draw when the server runs all day?

Each 32 GB 2Rx8 module operates at 1.10 V without a heat spreader; total kit power scales linearly with all twelve slots populated, and registered buffering keeps per-DIMM thermals within standard server airflow limits.
