Capacity and Compatibility

This 384GB kit contains six 64GB DDR5 RDIMMs built to the exact specifications the Supermicro H14DSG-OD motherboard expects. Registered ECC modules with a 2Rx4 organisation and 1.1V operation allow the board to recognise the full population at rated speed.

Sustained Operation

Registered architecture buffers the command and address signals so the memory controller remains stable when every slot is filled. ECC corrects single-bit errors on the fly, preventing silent data corruption during long-running workloads.

Critical Specification

The modules run at DDR5 4800 with CL40 latency at 1.1V in a 288-pin RDIMM form factor; only boards that support this precise combination of speed, timing, voltage and registered signalling will operate the kit at its rated capacity.

Questions about this item

How much power do these 1.1 V DDR5-4800 RDIMMs draw when the server runs continuously?

Each module operates at 1.10 V; total draw depends on the platform's memory controller and population rules, so consult the Supermicro H14DSG-OD manual for per-DIMM and full-kit figures.

What must my Supermicro H14DSG-OD motherboard already support to use this 6×64 GB kit?

The board needs six 288-pin DDR5 RDIMM slots, support for 2Rx4 registered ECC modules at 4800 MT/s, and a memory controller that can address 384 GB total capacity.

Can I mix this CL40 kit with existing DDR5 RDIMMs of different speeds or ranks in the same H14DSG-OD?

Mixing speeds, ranks or latencies is not recommended; the memory controller will default to the slowest common settings and may not initialise all six slots reliably.
