Supermicro H13SSF 256GB DDR5 Kit

This NEMIX RAM kit delivers 256GB across four 64GB DDR5 5600 Registered ECC RDIMMs built for the Supermicro H13SSF motherboard. The modules run at CL46 with a 1.1V operating voltage and a 2Rx4 rank configuration. Registered buffering and on-die ECC protect data integrity in fully populated server channels.

Suited for H13SSF capacity upgrades

Administrators expanding a Supermicro H13SSF to its maximum supported memory will find the exact rank, voltage and timing the board expects. Builders using UDIMM or SODIMM slots, or boards that require different speeds or ranks, must select memory matched to those platforms instead.

Verified fitment replaces guesswork

The kit is validated for the H13SSF memory-population rules so every slot initialises at the rated 5600 MT/s without manual tuning. No heat spreaders are included and no software utilities accompany the modules; installation follows the motherboard manual’s DIMM sequence.

Questions about this item

What motherboard and memory architecture must I already have for this 256GB DDR5 5600 ECC Registered RDIMM kit to work?

You need a Supermicro H13SSF motherboard with DDR5 RDIMM slots that support 2Rx4 Registered ECC modules at 1.1V and CL46 timing, and the board must allow four DIMMs populated.

How do these 2Rx4 DDR5 5600 CL46 RDIMMs behave alongside older DDR5 RDIMMs I might keep in the same server?

Mixing different ranks, speeds, or CAS latencies can force the memory controller to downclock all modules to the lowest common setting and may prevent full 256GB recognition.

How can I verify the kit is running at its rated DDR5 5600 CL46 1.1V after installation?

Enter the BIOS or use a hardware inventory tool to confirm all four 64GB modules show as 5600 MT/s, CAS 46, 1.1V, Registered ECC, and 2Rx4 organization.
