Server memory kit for Supermicro H14DSG-OM

This 768GB kit contains 16 modules of 48GB DDR5 RDIMM memory. It is built for administrators upgrading a Supermicro H14DSG-OM motherboard that requires registered ECC modules in every slot. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at the rated speed.

DDR5 RDIMM population limits

Registered DIMMs buffer the command and address signals, allowing the memory controller to drive a fully populated 16-slot configuration without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption. The motherboard manual defines the approved DIMM population order and maximum supported capacity per socket, which must be followed for stable operation.

16-module 48GB configuration

The kit delivers 768GB total capacity across 16 identical 48GB modules. Each module is a 2Rx8 registered ECC RDIMM rated at DDR5-4800 (PC5-38400) with CL40 latency at 1.1V. Verify that your specific Supermicro H14DSG-OM configuration supports this total capacity and 16-module layout before purchase.

Questions about this item

Should I choose the 16 x 48 GB kit or a smaller kit for my Supermicro H14DSG-OM?

The 16 x 48 GB kit provides 768 GB total. Select it only if your motherboard manual confirms support for 16 populated RDIMM slots at that capacity.

What does DDR5 4800 CL40 mean for real-world server throughput?

The modules run at 4800 MT/s with a CAS latency of 40 cycles, delivering the rated PC5-38400 bandwidth when the memory controller is fully populated with registered ECC DIMMs.

How does the 288-pin RDIMM interface limit maximum capacity on this board?

Each 288-pin registered slot accepts one 48 GB 2Rx8 module; the 16-slot kit reaches 768 GB, but the board's population rules may restrict usable slots per channel.
