  • 64 GB kit (2×32 GB) expands Supermicro H13SSH-E capacity to full rated speed
  • DDR5-4800 CL40 at 1.1 V matches the board's exact timing and voltage requirements
  • Registered ECC RDIMM with 2Rx8 rank offloads the controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor fits the motherboard's DIMM slots — not a UDIMM or SODIMM
  • Built with major OEM Samsung, Micron or Hynix chips for enterprise-grade reliability

Supermicro H13SSH-E DDR5 kit

This 64GB kit provides two 32GB DDR5-4800 Registered ECC RDIMMs built to the exact specifications the Supermicro H13SSH-E motherboard expects. The modules run at 1.1V with CL40 latency and a 2Rx8 organisation, ensuring the memory controller recognises full capacity at rated speed without manual tuning.

Registered ECC stability

Registered buffering reduces electrical load on the memory controller so every slot can be populated at full density, while on-die ECC detects and corrects single-bit errors before they cause silent data corruption or unexpected reboots in production workloads.

Population rules and manual check

Server memory support varies by model, so verify the board manual for approved DIMM population order, maximum supported capacity per slot, and installation sequence before ordering. This kit uses 288-pin DDR5 RDIMMs and will not fit UDIMM or SODIMM slots.

Questions about this item

Will the 2Rx8 registered DIMMs need any firmware updates or rank-sparing configuration changes during the server's service life?

No firmware updates or rank-sparing changes are required; the modules are spec-matched to the H13SSH-E memory controller and run at their rated DDR5-4800 CL40 1.1 V settings for the product's lifetime.

What limit appears first when the kit runs continuously at DDR5-4800 CL40 1.1 V in a fully populated H13SSH-E?

The memory controller's maximum supported speed of 4800 MT/s is the first ceiling; the modules operate at that rated speed with CL40 latency and 1.1 V, so no higher frequency or tighter timing is possible on this platform.

How much extra noise or heat should I expect from the 2 x 32 GB RDIMMs running all day in a fully populated H13SSH-E chassis?

The modules have no heat spreader and draw 1.1 V at DDR5-4800, so they add only the normal thermal load of registered ECC DDR5; any audible noise comes from the chassis fans responding to that load.
