768GB DDR5-4800 ECC RDIMM kit

This 768GB kit contains sixteen 48GB DDR5-4800 Registered ECC RDIMMs built for the Supermicro H14DSG-O-CPU motherboard. Each module runs at 1.10V with CL40 latency and a 2Rx8 organisation. The registered design lets the memory controller address every slot at full population without signal degradation.

Replaces partial or mixed-capacity DDR5 sets

Upgrading from a partially filled chassis or a slower DDR5 configuration is worthwhile when the workload demands the full 768GB at the board's native 4800 MT/s. The kit matches the exact rank, voltage and timing the platform expects, so all slots initialise at rated speed without manual tuning.

Sustained enterprise workloads

Registered buffering and on-die ECC keep data integrity intact during continuous, multi-threaded server tasks. The 1.10V operating point maintains thermal stability across all sixteen modules when the system runs fully populated for extended periods.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the DIMM slots on my Supermicro H14DSG-O-CPU motherboard?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the H14DSG-O-CPU requires, so every module seats directly in the board's DDR5 DIMM slots.

What is the correct population order when installing all 16 modules on the H14DSG-O-CPU?

Follow the motherboard manual's DIMM population sequence for a full 16-DIMM configuration; the kit's 2Rx8 registered ECC modules must be placed in the exact slots the manual specifies to initialise at DDR5-4800 CL40.

Do these registered ECC RDIMMs need any firmware updates or periodic reconfiguration during their service life?

No firmware updates or reconfiguration are required; the modules operate at 1.1V with on-die ECC and registered buffering for the duration of their installed life.
