  • Verified fitment for Supermicro H14DSG-OM motherboard ensures full-speed recognition

Exact-match upgrade kit

This 288GB kit contains six 48GB DDR5 6400 RDIMMs built to the Supermicro H14DSG-OM memory controller specification. Registered ECC modules with 2Rx8 organisation and CL52 timing at 1.1V are recognised at full capacity and rated speed without manual tuning.

Enterprise stability features

Registered architecture buffers the command bus so all slots run fully populated while ECC corrects single-bit errors on the fly. These mechanisms prevent silent data corruption and unplanned reboots in production workloads.

288-pin RDIMM form factor

Modules use the standard DDR5 RDIMM connector required by the target motherboard, not UDIMM or SODIMM layouts. Population order and maximum supported capacity must be verified in the system manual before installation.

Questions about this item

Will the six 48GB modules need any firmware updates or re-seating after installation in the H14DSG-OM?

The kit is built to the exact rank, voltage and timing the board expects so it is recognised at full capacity and rated speed on first boot; no firmware step is required.

What is the first limit reached when all six slots run continuously at DDR5-6400 CL52?

With 1.10 V registered ECC modules the memory controller thermal ceiling is reached before the DIMMs themselves throttle, so sustained throughput is bounded by the platform not the memory.

How much power do the six 2Rx8 sticks draw and what heat do they add when the server runs all day?

At 1.1 V the complete 288 GB kit consumes only a few watts per module, adding minimal heat and no audible noise since the RDIMMs have no heat spreaders or fans.
