288GB DDR5-6400 ECC RDIMM kit

This NEMIX RAM kit delivers 288GB across six 48GB DDR5-6400 registered ECC modules. It targets administrators upgrading a Supermicro H13SVW-N motherboard that requires 288-pin RDIMMs with 2Rx8 organisation. The exact-match specifications ensure the memory controller recognises full capacity at rated speed without manual tuning.

Sustained-load behaviour

Registered architecture buffers address and command signals, letting all six slots stay populated at DDR5-6400 without signal degradation. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable under continuous server workloads.

Upgrade context

This kit replaces smaller-capacity DDR5 RDIMMs or incomplete populations that leave memory channels unbalanced. The jump is worth it when your workload needs the full 288GB at native DDR5-6400 throughput and your board’s population rules support six 2Rx8 modules. It does not suit systems limited to UDIMMs, SODIMMs, or lower maximum capacities per slot.

Questions about this item

How much power does each 48 GB 1.1 V DDR5-6400 RDIMM draw when the server runs continuously?

Each module operates at 1.1 V, the standard DDR5-6400 voltage, so power draw per DIMM is determined by that voltage and the 2Rx8 density rather than by any higher-voltage profile.

What must the motherboard provide for this 6-module 288 GB kit to be recognised at its rated 6400 MT/s speed?

The board needs 288-pin DDR5 RDIMM slots that support 2Rx8 registered ECC DIMMs at 1.1 V with CL52 timing, plus a memory controller able to address the full 288 GB across six populated slots.

Will these 2Rx8 CL52 registered ECC modules run at full speed alongside any older DDR5 DIMMs I might keep installed?

Mixing ranks, voltages or timings can force the controller to down-clock all slots; for guaranteed DDR5-6400 operation the board should be populated only with matching 2Rx8 1.1 V CL52 RDIMMs.
