Capacity and fit

This 32 GB kit contains two 16 GB DDR5 RDIMM modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. It is built specifically for the Supermicro H13SSW motherboard and will not fit systems that require UDIMM or SODIMM form factors.

Build and daily handling

The modules use a 288-pin registered design without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller so all slots can be populated, while on-die ECC corrects single-bit errors to prevent silent data corruption.

Platform limits

DDR5 4800 is the baseline speed for this generation; the memory controller will not run these modules faster without explicit motherboard support. Capacity per DIMM is fixed at 16 GB, so total system memory is constrained by the number of slots the H13SSW provides and its qualified vendor list.

Questions about this item

Does DDR5 4800 with CL40 run at its rated speed on the Supermicro H13SSW?

The kit is spec-matched to the H13SSW memory controller, so the 4800 MT/s data rate and CL40 timing are recognised and run at full rated speed when populated per the board's rules.

Will a 288-pin RDIMM fit the H13SSW DIMM slots, and how many modules does this kit provide?

The board requires 288-pin Registered DIMMs; this kit supplies two 16 GB RDIMMs that match the slot keying and form factor exactly.

What is the correct population order for these two 1Rx8 RDIMMs on the H13SSW?

Consult the H13SSW manual for the approved DIMM population sequence; install the two modules in the slots specified for a two-DIMM configuration to ensure full capacity and stability.
