Exact-match server kit

This NEMIX RAM kit delivers 128GB of DDR5 memory across eight 16GB registered DIMMs. It is built for administrators upgrading a Supermicro H13SSF motherboard that requires DDR5-5600 RDIMMs with ECC.

Registered ECC stability

Each module uses a 288-pin RDIMM form factor with 1Rx8 organisation and runs at 1.1V CL46. The registered buffer reduces electrical load on the memory controller when all slots are populated, while on-die ECC corrects single-bit errors before they affect workloads.

Replaces partial or slower sets

The kit replaces smaller-capacity or lower-speed DDR5 RDIMMs when the board's population rules allow eight modules at full frequency. It is not for systems limited to fewer slots, UDIMM-only platforms, or builds that need a different voltage or latency profile.

Questions about this item

What speed does the DDR5 5600 interface actually run at on the Supermicro H13SSF?

The kit is rated DDR5 5600 (PC5-44800) and will operate at that speed when the motherboard memory controller is configured for DDR5-5600.

What physical slot and form factor do these modules need on the H13SSF?

Each 16 GB module is a 288-pin RDIMM; the board requires registered DIMMs, not UDIMM or SODIMM, and all eight slots must accept this form factor.

How are the eight DIMMs installed and which step is often missed?

Populate the eight slots in the exact order shown in the Supermicro H13SSF manual; the common mistake is skipping the prescribed population sequence, which prevents full 128 GB recognition.
