  • 768 GB total capacity from eight 96 GB modules for high-density server workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput on supported platforms
  • 1 V operation reduces power draw per module in fully populated configurations
  • Registered ECC with 2Rx4 organisation offloads the memory controller and corrects single-bit errors
  • 288-pin RDIMM form factor matches the Supermicro H14SST-G motherboard slot requirement

Supermicro H14SST-G DDR5 Upgrade

This 768GB kit contains eight 96GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H14SST-G motherboard. It targets administrators who need maximum memory capacity on that specific platform without mixing module sizes.

2Rx4 Registered ECC at 1.1V

The modules use a 2Rx4 organisation, 1.10V operating voltage and CL40 latency, matching the memory controller expectations for full-speed operation across all populated slots. ECC and registered buffering protect data integrity under sustained load.

Eight DIMMs Must Follow Manual Order

Installing all eight modules requires strict adherence to the motherboard's population sequence; skipping the manual often results in partial capacity recognition or boot failure. No heat spreaders are fitted, so airflow clearance around each 288-pin slot is essential.

Questions about this item

What does the 4800 MHz speed actually deliver once all eight 96 GB modules are installed in a Supermicro H14SST-G?

The kit runs at DDR5 4800 with CL40 timing and 1.1 V, so the memory controller sees the full 768 GB at rated frequency when all slots are populated.

How does the PC5-38400 designation and registered ECC design affect real-world throughput?

PC5-38400 identifies the DDR5 4800 data rate; the registered buffer reduces electrical load on the controller and ECC corrects single-bit errors, keeping the system stable at full capacity.

What physical slot and form factor do these modules need on the H14SST-G motherboard?

They are 288-pin DDR5 RDIMMs, the exact registered form factor the board requires — not UDIMM or SODIMM.
