1 TB DDR5 ECC RDIMM kit for Supermicro H14SHM

This 1 TB kit contains eight 128 GB DDR5 5600 registered ECC DIMMs built to the exact rank, voltage and timing the Supermicro H14SHM memory controller expects. It is intended for administrators who need to fully populate the board with validated server memory.

Registered architecture

The registered design buffers every command so all eight slots run at the rated 5600 MT/s without signal degradation during sustained workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise force unplanned reboots in production environments.

Verify DIMM population rules before ordering

Consult the Supermicro H14SHM manual for the approved population sequence, maximum capacity per channel and any BIOS version requirements. The board requires 288-pin RDIMMs; UDIMMs or SODIMMs will not fit and cannot be used as alternatives.

Questions about this item

At 1.1 V and DDR5 5600 speed, how much heat do eight 128 GB RDIMMs generate when the server runs 24/7?

Each module operates at the standard 1.1 V DDR5 voltage, so total power draw scales with eight 128 GB sticks. Registered buffering and ECC add minimal overhead; expect typical DDR5 RDIMM thermals under sustained load.

What motherboard and CPU combination must I already own for this 1 TB kit to function?

You need a Supermicro H14SHM motherboard with a CPU that supports DDR5 5600 registered ECC memory. The 288-pin RDIMM form factor and 2Rx4 organization must match the board's qualified vendor list.

Can I mix this 2Rx4 CL46 DDR5 5600 kit with other DDR5 RDIMMs of different rank or latency on the same H14SHM board?

Mixing ranks or timings is not recommended. The board's memory controller expects identical 2Rx4 CL46 modules across all populated slots to run at the rated 5600 MT/s without down-clocking or stability issues.
