Exact-match upgrade for Supermicro H14DSG-OM

This 64GB kit contains four 16GB DDR5 RDIMMs rated at 4800MHz with CL40 latency and 1.1V operation. It is built for administrators who need the precise rank, voltage and timing the server memory controller expects so the full capacity is recognised and runs at rated speed.

Registered ECC limits for full population

Registered architecture offloads the memory controller, allowing every slot to be populated at full capacity while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor is mandatory for this board; UDIMM or SODIMM modules will not fit or function.

1Rx8 rank decides compatibility

Each module uses a single-rank 1Rx8 organisation that matches the motherboard population rules. Verify your system manual for supported capacities and approved DIMM installation order before purchase.

Questions about this item

Should I choose the 4x16GB kit or a different capacity for my H14DSG-OM?

The 4x16GB kit fills four slots with 64GB total, matching the board's registered DIMM population rules for full-capacity operation.

What does the DDR5-4800 speed deliver once installed in the server?

The modules run at 4800 MT/s with CL40 latency at 1.1V, giving the memory controller the exact timing and voltage it expects for rated throughput.

How does the 288-pin RDIMM interface limit what I can install?

The board requires 288-pin registered DIMMs; unbuffered UDIMMs or SODIMMs will not fit or function in these slots.
