Exact-match DDR5 server kit

This NEMIX RAM kit delivers 128 GB across four 32 GB DDR5-4800 RDIMMs built to the Supermicro H13SSH motherboard's exact rank, voltage and timing requirements. Registered ECC architecture with 2Rx8 organisation and CL40 latency lets the board recognise full capacity at rated speed. Modules run at 1.1 V without heat spreaders.

Replaces partial or mismatched sets

The kit upgrades systems running fewer modules, slower DDR5 speeds or unbuffered memory that cannot fill every slot at full capacity. Registered buffering offloads the memory controller so all four slots operate together, while ECC corrects single-bit errors before they cause silent corruption or reboots. The jump is worth it when workloads demand maximum supported density and uptime.

Fits H13SSH memory rules

Installation follows the motherboard's approved population order for 288-pin RDIMMs, freeing administrators from trial-and-error seating. No extra cooling hardware is required because the modules operate at standard 1.1 V. The kit leaves other expansion slots and power headers untouched, keeping the chassis layout unchanged.

Questions about this item

Will these 288-pin RDIMMs fit the memory slots on my Supermicro H13SSH motherboard?

Yes. The kit uses the 288-pin DDR5 RDIMM form factor that the H13SSH requires; UDIMM or SODIMM modules will not seat in those slots.

What is the correct installation order for the four 32 GB modules on the H13SSH?

Populate the slots in the sequence specified in the Supermicro H13SSH manual; the board's population rules determine which channels must be filled first for full 128 GB recognition.

Do these registered ECC modules need any firmware updates or periodic maintenance after installation?

No firmware updates are required for the memory itself; ECC error correction operates automatically, and the modules have no moving parts or consumable components to service.
