Exact-match DDR5-5600 RDIMM kit

This NEMIX RAM kit delivers 128GB as two 64GB DDR5-5600 (PC5-44800) registered ECC modules. Each stick runs at 1.1V with CL46 latency in a 2Rx4 layout. The 288-pin RDIMM form factor matches the slot and electrical requirements of the Supermicro H13SSW motherboard.

For servers needing registered ECC at rated speed

IT teams populating every DIMM slot on an H13SSW board get full-capacity recognition and stable operation without down-clocking. Builders using unbuffered UDIMMs, non-ECC modules, or a different DDR generation will find the modules physically or electrically incompatible.

Verified fitment removes population guesswork

The kit is specified for the H13SSW memory-population rules, so the correct rank, voltage, and timing are presented to the memory controller on first boot. No extra software, heat spreaders, or adapters are included; the modules install directly into the board's 288-pin RDIMM slots.

Questions about this item

Does this 288-pin DDR5 RDIMM kit require a motherboard that supports registered ECC memory?

Yes, the Supermicro H13SSW motherboard must support 288-pin DDR5 registered ECC RDIMMs; the kit will not work in boards that only accept unbuffered UDIMMs or non-ECC modules.

Can I mix these 2Rx4 1.1V CL46 modules with existing DDR5 RDIMMs of a different rank or voltage?

Mixing ranks or voltages is not recommended; the memory controller expects identical 2Rx4 1.1V CL46 modules in each populated channel for stable operation at 5600 MT/s.

How do I confirm the system recognises the full 128 GB at 5600 MT/s after installation?

Enter the BIOS or UEFI and verify the memory information screen shows 128 GB total, 5600 MT/s speed, CL46 timings and ECC active for each installed DIMM.
