Capacity and Compatibility

This NEMIX RAM kit delivers 512 GB of DDR5 registered ECC memory in four 128 GB modules. It is built for the Supermicro H13SSH motherboard and matches the 288-pin RDIMM form factor that board requires.

Suitable Use Cases

The kit suits administrators upgrading a Supermicro H13SSH server to its maximum supported capacity with fully populated slots. Builders using UDIMM or SODIMM boards, or anyone needing non-ECC memory, should look elsewhere.

Deciding Specification

The registered ECC RDIMM design with 2Rx4 organisation is the single specification that determines fitment. Only motherboards wired for registered DDR5 can recognise and run these modules.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SSH motherboard slots?

Yes, the kit uses the 288-pin RDIMM form factor that the H13SSH requires and is verified for that board.

What population order should I follow when installing the four 128GB modules?

Consult the H13SSH manual for the approved DIMM population sequence; installing in the wrong order can prevent the system from recognising the full 512GB.

Do these registered ECC modules need any firmware updates or periodic replacement?

No firmware updates are required; the modules are designed for continuous server operation with ECC correcting single-bit errors on the fly.
