128GB DDR5 ECC RDIMM kit for Supermicro H14DSG-OM

This 128GB kit contains four 32GB DDR5-4800 registered DIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-OM memory controller expects. It is intended for administrators upgrading that specific server platform with validated ECC memory.

Registered ECC limits for DDR5-4800

The registered architecture buffers address and command signals so every slot can run fully populated at the rated 4800 MT/s speed. ECC corrects single-bit errors on the fly, preventing silent data corruption. The modules operate at 1.1V with CL40 latency and require a motherboard that supports 288-pin RDIMMs.

2Rx8 organisation decides fitment

Each module uses a 2Rx8 rank configuration that must match the motherboard's qualified vendor list and population rules. If your system requires a different rank structure or a UDIMM form factor, this kit will not be recognised or will run at reduced capacity. Check the manual before purchase.

Questions about this item

Should I choose the 128GB 4x32GB kit or a different capacity for my Supermicro H14DSG-OM?

The 128GB kit provides four 32GB modules that match the board's 2Rx8 rank requirement and 1.1V voltage, allowing full population at the rated DDR5 4800 speed.

What does the DDR5 4800 rating mean once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with CL40 latency, delivering the PC5-38400 bandwidth the platform expects when all four slots are populated.

How does the 288-pin RDIMM interface affect what I can actually use?

The registered 288-pin RDIMM form factor is required by the H14DSG-OM; it offloads the memory controller so every slot runs fully populated at 128GB total capacity with ECC active.
