Capacity and platform match

This NEMIX RAM kit provides 128 GB of DDR5 memory in a matched pair of 64 GB modules. It is built as an exact-fit upgrade for the Supermicro H13SSF motherboard, using the 288-pin Registered DIMM form factor that board requires.

Who this suits and who should look elsewhere

Server administrators expanding a Supermicro H13SSF system to its full memory capacity will find the correct rank, voltage and timing in one package. Builders who need unbuffered UDIMMs, SODIMMs or a different DDR generation cannot use this kit.

What to verify before ordering

Confirm the motherboard manual for approved DIMM population order and maximum supported capacity per slot. Ensure the system BIOS is updated to a version that recognises DDR5-4800 Registered ECC modules at 1.1 V.

Questions about this item

What motherboard must I already own for this 128GB DDR5 4800 kit to work?

The kit is validated for the Supermicro H13SSF motherboard, which uses the 288-pin DDR5 RDIMM form factor this memory provides.

How will these registered ECC modules behave if I keep older RDIMMs of different rank or speed installed?

Registered architecture offloads the memory controller, but mixing ranks or speeds can prevent full-capacity operation; populate slots per the H13SSF manual for stable 4800 MT/s performance.

How do I verify the system sees both 64GB modules at CL40 after installation?

Check the BIOS memory info or OS tool such as dmidecode: it should report 128GB total, DDR5-4800, CL40, 1.1V, 2Rx4 registered ECC on each DIMM.
