Show 24 more configurations
  • 512 GB total capacity from four 128 GB modules for maximum server memory density
  • DDR5 4800 MT/s speed with CL40 latency delivers rated bandwidth for demanding workloads
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated channels
  • 1 V operating voltage matches the motherboard memory controller specification exactly
  • Validated compatibility with the Supermicro H13SSL-N motherboard ensures correct fit and recognition

Purpose-built server upgrade

This 512 GB kit delivers four 128 GB DDR5 RDIMMs tuned for the Supermicro H13SSL-N motherboard. Registered ECC architecture with 2Rx4 organisation offloads the memory controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly. The modules operate at 1.1 V with CL40 latency at 4800 MT/s.

Verify before ordering

Check your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM variants will not fit or function. Confirm that your configuration allows four dual-rank modules at the rated voltage and timing.

Daily operation

Major-brand Samsung, Micron, or Hynix chips are mounted without heat spreaders, relying on server chassis airflow for cooling. The 288-pin registered connectors seat securely in the motherboard slots, and the buffered design maintains signal integrity across all four populated channels. Lifetime replacement coverage and free US-based technical support back the kit.

Questions about this item

What is included in the 512GB kit and do I need to buy anything else?

The kit contains four 128GB DDR5 4800MHz CL40 2Rx4 1.1V ECC Registered RDIMMs for a total of 512GB. No extra modules or accessories are required for installation.

How do I choose between the listed versions or capacities for my Supermicro H13SSL-N?

This is a single 512GB kit of four 128GB modules. Select this kit when your board's memory population rules call for four registered DIMMs at DDR5 4800 with 2Rx4 organisation.

What does the 4800MHz rating mean once the memory is installed in the server?

The modules will run at DDR5 4800 (PC5 38400) with CL40 latency at 1.1V, delivering the exact speed and timing the motherboard's memory controller expects when fully populated.
