  • 288-pin RDIMM form factor validated for Supermicro H13SSH motherboard compatibility

Kit Contents

This kit supplies 512GB of DDR5 server memory in eight 64GB Registered ECC RDIMMs. It is built for administrators upgrading a Supermicro H13SSH motherboard to its full supported capacity with modules that match the board's exact rank, voltage and timing requirements.

Fitment Guidance

The kit suits IT teams populating every slot on a compatible Supermicro H13SSH platform where registered ECC memory is mandatory. It is not for workstations or desktops that accept only unbuffered UDIMMs, nor for systems limited to lower maximum capacities or different DDR generations.

DDR5 4800 CL40 Specification

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.1V in a 2Rx4 organization. This precise speed, latency and voltage combination is what the H13SSH memory controller expects for stable operation at full population.

Highlights

  • 512 GB total capacity from eight 64 GB modules for high-density server workloads
  • DDR5 4800 MHz speed with CL40 latency matching the motherboard's rated timing
  • 1 V operating voltage reduces power draw per module at full load
  • Registered ECC 2Rx4 design enables full-slot population while correcting single-bit errors
  • 288-pin RDIMM form factor validated for Supermicro H13SSH motherboard compatibility

Questions about this item

What 288-pin DDR5 RDIMM form factor does the Supermicro H13SSH motherboard require for this 512GB kit?

The Supermicro H13SSH motherboard requires 288-pin DDR5 Registered RDIMM modules; this kit supplies eight 64GB 2Rx4 sticks at 1.1V CL40 that match the board's memory population rules.

In which slot order should the eight 64GB RDIMMs be installed on the H13SSH, and what step do builders often miss?

Follow the H13SSH manual's approved DIMM population sequence for eight modules; the step most often missed is verifying the exact slot order before seating all sticks.

When should the registered ECC RDIMMs be reseated or replaced to maintain error-correction reliability?

Reseat the RDIMMs if the system logs corrected ECC errors or fails to recognise the full 512GB at DDR5-4800; replace modules only if errors persist after reseating and firmware updates.
