  • 2TB total capacity enables large-scale workloads with 16 x 128GB modules
  • DDR5 4800 speed delivers PC5-38400 bandwidth for demanding server applications
  • ECC Registered RDIMM architecture corrects single-bit errors and buffers signals for full-slot stability
  • CL40 latency at 1.1V matches the Supermicro H13SSH-E memory controller requirements
  • 288-pin 2Rx4 form factor fits the exact DIMM slots and population rules of the target motherboard

Exact-match server kit

This 2 TB kit contains sixteen 128 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. Registered ECC design matches the Supermicro H13SSH-E memory controller so every slot is recognised at full capacity and rated speed.

Replaces mixed or partial population

Upgrading from a partially filled configuration or mixed-rank modules eliminates population-rule conflicts and lets the board run all channels fully populated. The jump is worth it when the workload demands maximum registered ECC capacity without down-clocking or stability compromises.

Fits 288-pin RDIMM slots only

The modules require a motherboard wired for 288-pin DDR5 RDIMMs with registered ECC support and the correct population sequence. They free the memory controller from electrical load through the registered buffer, enabling full-density operation across all channels. Not for systems that accept only UDIMM or SODIMM form factors.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SSH-E motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM form factor, which is the exact module type the Supermicro H13SSH-E motherboard requires for its memory slots.

What is the correct installation sequence for the 16 modules on this motherboard?

Consult the Supermicro H13SSH-E manual for the approved DIMM population order; the board's memory-controller rules dictate which of the 16 slots must be filled first for full 2TB recognition.

Do the modules have heat spreaders that could need cleaning or replacement over time?

No, the modules are supplied without heat spreaders, so there are no spreaders to clean, re-seat, or replace during the system's service life.
