Exact-match DDR5 server kit

The NEMIX RAM kit delivers 256GB of DDR5 5600 memory in two 128GB modules built for the Supermicro H14DST-F motherboard. Each module uses a 288-pin RDIMM form factor with registered ECC operation at 1.1V and CL46 latency. The 2Rx4 organisation matches the board's memory controller expectations so the full capacity is recognised at rated speed.

Sustained-load stability

Registered architecture buffers address and command signals, reducing electrical load on the memory controller when every slot is populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption during long-running workloads. The modules operate at the standard 1.1V without requiring additional cooling or voltage headroom.

DDR5 interface limits

DDR5 5600 (PC5-44800) sets the maximum transfer rate this kit can achieve on the platform. Population rules and maximum supported capacity are defined by the motherboard firmware, not by the modules themselves. Buyers who need higher speeds or larger total memory must verify what the specific board revision allows before ordering.

Questions about this item

How much heat and power does the 1.10V 2Rx4 registered DDR5 kit add when the server runs 24/7?

Each module operates at 1.10 volts with a 2Rx4 registered design, which reduces electrical load on the memory controller and keeps power draw and thermal output low even at full 256GB capacity.

What motherboard slot type must my Supermicro H14DST-F provide for these 288-pin RDIMMs to be recognised?

The board needs DDR5 288-pin RDIMM slots; the kit is built to the exact registered ECC specification that the H14DST-F memory controller expects.

Can I mix this 256GB 5600 CL46 registered ECC kit with other DDR5 RDIMMs of different speed or rank already installed?

Mixing is only reliable when all modules share the same 5600 speed, CL46 timing, 1.10V voltage, 2Rx4 rank and registered ECC design; otherwise the system will down-clock or fail to boot.
