Supermicro H13SSH memory kit

This 64GB kit contains four 16GB DDR5 RDIMM modules built for the Supermicro H13SSH motherboard. Each module runs at 4800MHz with CL40 latency at 1.1V. The registered ECC design matches the board's memory-controller requirements for full-capacity recognition.

Suited for populated server slots

The 1Rx8 registered ECC layout lets every slot run fully populated while correcting single-bit errors on the fly. Builders needing unbuffered UDIMM or SODIMM form factors should look elsewhere because this kit uses the 288-pin RDIMM interface the H13SSH requires.

Four modules at rated speed

Four 16GB modules deliver 64GB total capacity at the specified DDR5-4800 data rate. The kit handles workloads that fit within this capacity and speed envelope; configurations demanding larger densities or higher frequencies exceed what this package provides.

Questions about this item

Does my Supermicro H13SSH motherboard need a specific DIMM population order for this 64GB kit?

The kit is spec-matched to the H13SSH memory-population rules; consult your motherboard manual for the approved slot sequence so all four 16GB modules are recognised at full capacity.

Can I mix these Registered ECC RDIMMs with unbuffered UDIMMs already installed in the server?

No, the H13SSH requires 288-pin Registered RDIMMs; mixing registered and unbuffered modules prevents the memory controller from initialising the array.

How can I verify the kit is running at DDR5-4800 CL40 1.1V after installation?

Enter the BIOS or use a hardware-monitoring utility to confirm the memory frequency reads 4800 MT/s, CAS latency shows CL40, and the DIMM voltage reports 1.10V.
