Exact-fit 576 GB server kit

This NEMIX RAM kit delivers 576 GB across six 96 GB DDR5-6400 registered ECC RDIMMs built for the Supermicro H14SSL-NT motherboard. Each module runs at 1.10 V with CL52 timing and a 2Rx4 organisation that matches the board's memory controller requirements. The 288-pin form factor ensures correct physical fit and electrical signalling.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all six slots can operate at the rated 6400 MT/s without down-clocking. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 2Rx4 rank structure supports full-capacity population across every channel.

Thermals and power

Modules operate at the standard DDR5 1.10 V with no integrated heat spreader, relying on chassis airflow for cooling. Lower voltage reduces per-DIMM power draw compared with higher-voltage DDR5 variants. The registered design adds minimal latency while keeping signal integrity stable under continuous server workloads.

Questions about this item

How much heat and power will the 1.10V DDR5 6400 kit draw when the server runs continuously?

Each 96GB module operates at 1.10V with no heat spreader; the registered DDR5 design reduces electrical load on the memory controller so the fully populated kit stays within standard DDR5 thermal limits during 24/7 operation.

What motherboard slot and population rules must my Supermicro H14SSL-NT already have to accept this 6×96GB RDIMM kit?

The board needs six 288-pin DDR5 RDIMM slots and must support 2Rx4 registered ECC modules at 6400 MT/s; consult the H14SSL-NT manual for the exact population order before installing all 576GB.

Will the CL52 2Rx4 registered ECC modules work reliably alongside any older DDR5 RDIMMs I keep in the same H14SSL-NT?

Mixing ranks, voltages or timings is not supported; the kit is validated as a matched 6×96GB set at 1.10V CL52, so all slots should be populated with these identical modules for guaranteed stability.
