Exact-Match 1 TB Server Kit

This NEMIX RAM kit delivers 1 TB of capacity across eight 128 GB DDR5 RDIMMs. It is built for administrators upgrading a Supermicro X14DBG-LC+ motherboard that requires registered ECC memory. The modules arrive new and ready for immediate installation in a production environment.

DDR5-6400 CL52 4Rx4 Registered ECC

The decisive specification is the 4Rx4 registered ECC organisation running at DDR5-6400 with a CL52 latency at 1.1 V. This exact rank, voltage and timing combination is what the memory controller expects to recognise full capacity and operate at the rated speed without down-clocking or training failures.

Eight-Slot Population for Supermicro X14DBG-LC+

The kit fills all eight DIMM slots with 288-pin RDIMMs, so the board must support eight registered modules in its validated population order. Registered buffering offloads the memory controller, allowing every slot to run fully populated at full speed, while on-die ECC corrects single-bit errors before they affect workloads. Builders needing UDIMM, SODIMM or non-ECC memory cannot use this kit.

Questions about this item

What does the DDR5 6400 (PC5 51200) rating mean for actual throughput in a Supermicro X14DBG-LC+?

The kit operates at DDR5 6400 with CL52 timings and 1.1V, so each of the eight 128 GB RDIMMs transfers data at the motherboard's supported DDR5 6400 rate when all slots are populated per the board's population rules.

How does the 288-pin RDIMM registered ECC interface affect what the memory controller can do?

Registered buffering reduces electrical load on the controller, allowing all eight slots to run at full 6400 MT/s with ECC correcting single-bit errors on the fly.

What physical space and slot layout does the 8x128 GB 4Rx4 kit require?

Eight 288-pin DDR5 RDIMM slots are needed; the modules have no heat spreader, so they fit standard server DIMM spacing on the X14DBG-LC+.
