  • 512 GB total capacity from eight 64 GB modules for dense server workloads
  • DDR5 4800 MT/s speed with CL40 latency matches the memory controller specification
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 10 V operating voltage and 2Rx4 rank layout align with Supermicro H14SSL-N requirements
  • 288-pin RDIMM form factor ensures correct physical and electrical fit in every slot

Capacity and purpose

This 512GB kit contains eight 64GB DDR5-4800 RDIMM modules rated at CL40 and 1.1V. It targets administrators upgrading a Supermicro H14SSL-N server to its maximum supported memory in a single, validated package.

Registered ECC and 288-pin fit

The registered design buffers address and command signals so the memory controller can drive all eight slots at full population without timing degradation. ECC corrects single-bit errors on the fly while the 288-pin RDIMM form factor matches the motherboard's physical and electrical requirements.

DDR5-4800 ceiling

The PC5-38400 standard caps transfer rate at 4800 MT/s, so workloads needing higher bandwidth will not scale beyond this limit on this platform. Buyers requiring faster memory speeds or non-registered DIMMs must select a different motherboard and memory combination.

Questions about this item

What DDR5 speed and PC5 rating does this 512GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 data rate, matching the Supermicro H14SSL-N memory controller specification.

What physical slot type and pin count does each 64GB module use?

Each module is a 288-pin DDR5 RDIMM, the registered form factor required by the H14SSL-N motherboard.

How should the eight RDIMMs be populated, and what step is often missed?

Follow the H14SSL-N manual for the approved DIMM population order; the step most often missed is verifying the exact slot sequence before installing all eight modules.
