  • DDR5 6400 speed with CL52 latency for rated performance
  • 1 V operation matches server memory controller requirements
  • Registered ECC design corrects single-bit errors automatically
  • 288-pin RDIMM form factor fits Supermicro H14DSG-O-CPU motherboard

Exact-match server kit

This 256GB kit contains four 64GB DDR5-6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU motherboard expects. The modules operate at 1.1V with CL52 latency so the board recognises the full capacity and runs at rated speed.

Pre-installation checks

Confirm the motherboard manual for supported capacities, approved DIMM population order and any BIOS version requirements before ordering. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function.

Build and daily implications

Registered buffering offloads the memory controller so every slot stays stable when fully populated while ECC corrects single-bit errors on the fly to prevent silent data corruption. The modules have no heat spreader so ensure the server chassis provides adequate airflow across the DIMM slots.

Questions about this item

Does the 256GB kit ship as four 64GB modules or do I need to buy additional DIMMs?

The package contains four 64GB DDR5 RDIMMs, giving the full 256GB capacity in a single kit.

Should I choose this 2Rx4 CL52 kit or a different rank or latency for the Supermicro H14DSG-O-CPU?

This 2Rx4 CL52 1.1V kit matches the exact rank, voltage and timing the board expects for full-capacity operation.

Will the DDR5 6400 speed actually run at 6400 MT/s once installed in the Supermicro H14DSG-O-CPU?

The modules are spec-matched to the motherboard's memory controller, so they are recognised at the rated DDR5 6400 speed when populated per the board's rules.
