Exact-match DDR5 upgrade

This 384GB kit delivers eight 48GB DDR5 6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. It installs as a matched set so the server recognises the full capacity and runs at the rated PC5-51200 speed.

Registered ECC architecture

The 288-pin RDIMM form factor and 2Rx8 organisation offload the controller, allowing every slot to be populated at 1.10V without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

384GB capacity ceiling

Eight modules fill the board's supported DIMM population for maximum density at DDR5-6400 CL52. Builds requiring more memory than this kit provides must use a different platform, as the installed modules already occupy the full slot count.

Questions about this item

How does the 1.10 V operating voltage limit headroom during sustained heavy workloads?

The modules run at the standard DDR5 server voltage of 1.10 V; this is the voltage the memory controller expects for stable full-speed operation across all eight slots.

What thermal or acoustic impact should I expect when all eight RDIMMs are fully populated and running continuously?

The kit has no heat spreaders; registered DDR5 RDIMMs rely on chassis airflow, so ensure your server fans provide adequate cooling across the 288-pin DIMM slots for continuous duty.

Which motherboard features must my system already provide for this 384 GB kit to function?

Your Supermicro H14DSG-OM motherboard must support 288-pin DDR5 RDIMM slots, registered ECC memory, 2Rx8 organization, and a population rule that allows eight 48 GB modules at DDR5-6400.
