  • 64 GB total capacity from four 16 GB modules for full server memory population
  • DDR5 4800 MHz CL40 at 1.1 V matches the board's rated speed and voltage
  • ECC and registered design correct single-bit errors and buffer the memory controller
  • 288-pin RDIMM form factor fits the Supermicro H14DSG-OD motherboard exactly
  • 1Rx8 rank organisation follows the system's population rules for stable operation

System-specific DDR5 upgrade

This 64 GB kit contains four 16 GB DDR5 4800 MHz registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-OD motherboard expects. It is intended for administrators who need to populate all available slots with validated modules. Buyers whose platform requires unbuffered UDIMMs or a different DDR generation cannot use this memory.

Registered ECC limits

The registered architecture buffers address and command signals so the memory controller can drive a fully populated configuration at the rated 4800 MT/s data rate. ECC corrects single-bit errors automatically to prevent silent data corruption. Systems that only accept unbuffered memory or lack ECC support will not work with these modules.

1Rx8 rank and 1.1 V spec

Each module is a single-rank 1Rx8 device operating at 1.10 V with CL40 latency, matching the board’s qualified voltage and timing profile. Deviating from this rank structure or voltage will prevent the system from recognising the full 64 GB capacity at the rated speed.

Questions about this item

Should I choose the 64GB 4x16GB kit or a different capacity for my Supermicro H14DSG-OD?

The 64GB kit provides four 16GB modules to fill four DIMM slots at DDR5-4800 CL40 1.1V registered ECC. Consult your motherboard manual for supported capacities and population order before deciding.

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

The modules run at 4800 MT/s with a CAS latency of 40 cycles at 1.1V. Registered ECC buffering lets all four slots operate at this rated speed when populated per the board's rules.

Does the 288-pin RDIMM interface limit the speed or capacity I can use?

The 288-pin registered DDR5 form factor is required by the H14DSG-OD. It supports the kit's 4800 MT/s PC5-38400 data rate and 64GB total capacity when installed in the correct slot sequence.
