Exact-Match DDR5 Server Kit

This 1 TB kit contains eight 128 GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSL-NT memory controller expects. The modules are recognised at full capacity and run at their rated 4800 MT/s speed without manual tuning.

Suited For And Not Suited For

The kit fits administrators populating every slot of a compatible Supermicro H13SSL-NT platform that requires 288-pin Registered DIMMs with ECC. It does not serve builders needing unbuffered UDIMMs, SODIMM form factors, lower-density modules or non-ECC memory for workstation or consumer boards.

Capacity And Headroom

Eight dual-rank modules deliver 1 TB of registered ECC capacity, allowing the board to run fully populated at the rated 4800 MT/s data rate while ECC corrects single-bit errors on the fly. Headroom ends when the platform's maximum supported DIMM count or total memory limit is reached.

Questions about this item

Does the Supermicro H13SSL-NT motherboard need to support DDR5 4800 Registered ECC memory for this kit to function?

Yes, the board must accept DDR5 4800 RDIMM modules with ECC and registered operation; the kit is spec-matched to the H13SSL-NT so it will be recognised at full 1 TB capacity and rated speed.

Will the 2Rx4 rank organisation of these modules work with the H13SSL-NT population rules when all eight slots are filled?

The kit uses the exact 2Rx4 registered layout the motherboard expects, allowing every slot to run fully populated at 128 GB per DIMM without downclocking.

How can I confirm the kit is running at DDR5 4800 CL40 1.1 V after installation?

Check the BIOS memory information screen or a tool such as dmidecode; it should report 4800 MT/s, CAS latency 40 and 1.1 V on all eight modules.
