Exact-match DDR5 ECC kit for Supermicro H13SSF

This 128GB kit uses two 64GB DDR5 5600 RDIMMs built to the Supermicro H13SSF memory-population rules. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed. The kit is supplied new and ready for server deployment.

288-pin RDIMM form factor with no heat spreader

Registered buffering and ECC correction keep data integrity intact across all populated channels. The 1.10V operating voltage matches the board specification, and the 2Rx4 rank layout fits the approved population order. Modules slot directly into the 288-pin DDR5 sockets without adapters.

Replaces partial or slower memory configurations

Upgrading from smaller-capacity or lower-speed DIMMs unlocks the full 128GB capacity the platform supports. The jump is worth it when workloads demand maximum registered ECC capacity at DDR5 5600 without mixing ranks or voltages. Buyers who need a different capacity, a UDIMM form factor, or non-ECC memory should look elsewhere.

Questions about this item

Does the DDR5 5600 PC5-44800 interface cap the memory speed at 5600 MT/s in this Supermicro H13SSF kit?

Yes, the modules are rated DDR5 5600 (PC5-44800) and will run at that speed when the board's memory controller supports it.

What physical slot and form factor do these 288-pin RDIMMs need on the H13SSF motherboard?

They require standard 288-pin DDR5 RDIMM slots; the board must accept registered DIMMs, not UDIMM or SODIMM.

What is the correct population order for the 2x64 GB 2Rx4 kit, and which step do installers often miss?

Follow the H13SSF manual's DIMM population sequence for 2Rx4 registered modules and ensure each DIMM clicks fully into the slot.
