  • 512 GB total capacity from eight 64 GB modules for maximum server density
  • DDR5 4800 MT/s at CL40 delivers rated throughput without down-clocking
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 10 V operation matches the platform spec for stable fully-populated slots
  • 288-pin RDIMM form factor verified for Supermicro H14SSL-NT motherboard

Exact-fit server memory

This 512GB kit delivers eight 64GB DDR5 RDIMM modules rated at 4800MHz CL40 with ECC and registered buffering. It is built for the Supermicro H14SSL-NT motherboard and targets administrators who need maximum registered capacity in every slot.

Verify board population rules

Confirm the motherboard manual for supported DIMM capacities per channel and the required installation sequence before ordering. The 288-pin registered form factor will not fit UDIMM or SODIMM slots and the kit must match the board's voltage and rank expectations.

Thermals noise and power

Modules operate at 1.1V without heat spreaders, relying on chassis airflow for cooling. Registered architecture reduces electrical load on the memory controller when fully populated, and ECC corrects single-bit errors without adding audible noise.

Questions about this item

Does the 512GB kit include all 8 modules or must I buy them separately?

The kit contains 8x64GB DDR5 RDIMM modules in one package, no additional purchases required.

Should I choose this CL40 4800MHz kit or a different speed for the Supermicro H14SSL-NT?

This kit matches the exact DDR5-4800 CL40 2Rx4 registered ECC specification the H14SSL-NT expects for full-capacity operation.

Will the system actually run at 4800MHz with all 8 slots populated on the H14SSL-NT?

Yes, the registered DDR5 architecture and matched 1.1V CL40 timing let the memory controller recognise the full 512GB at rated speed when populated per the board's rules.
