  • 128 GB capacity lets you fully populate the Supermicro H14SHM
  • DDR5-5600 speed matches the board's rated memory controller frequency
  • Registered ECC design corrects single-bit errors and stabilises every slot
  • 1 V operation meets the platform's standard DDR5 voltage spec
  • 2Rx4 rank organisation aligns with the motherboard's population rules

Capacity and fitment

This 128 GB DDR5 module is built for the Supermicro H14SHM motherboard. The 288-pin Registered RDIMM form factor matches the board's memory-population rules so the controller recognises the full capacity at its rated 5600 MT/s speed.

Sustained-load behaviour

Registered architecture buffers the command and address signals, letting every slot run fully populated at 1.1 V without overloading the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption during long compute runs.

Thermals and power

The modules operate at the standard 1.10 V DDR5 voltage and have no heat spreader, relying on chassis airflow for cooling. Power draw scales with the 128 GB density and 5600 MT/s data rate under typical server workloads.

Questions about this item

How much heat does the 128 GB DDR5 5600 CL46 1.10 V module add when the server runs 24/7?

The module runs at the standard DDR5 voltage of 1.10 V with no heat spreader, so it adds only the normal thermal load of a 128 GB registered ECC DIMM at 5600 MT/s; ensure your chassis airflow meets the motherboard's cooling guidelines.

What must the motherboard provide for this 288-pin RDIMM to be recognised at full capacity?

The board must be a Supermicro H14SHM with DDR5 RDIMM slots that support 2Rx4 registered ECC modules at 1.10 V and follow the manual's population rules for 128 GB per slot.

Can I mix this 2Rx4 CL46 DDR5 RDIMM with older DDR5 modules of different rank or latency?

Mixing ranks or timings is not recommended; the memory controller will down-clock all slots to the slowest common settings and may disable ECC or registered buffering if the population rules are violated.
