Server memory kit

This 128GB kit contains two 64GB DDR5 5600 ECC RDIMM modules built for the SuperMicro B13SEE-CPU-25G motherboard. Registered signalling and on-die ECC protect data integrity in multi-socket server workloads. The dual-rank 2Rx4 organisation maximises density per channel without exceeding the platform's electrical load limits. IT teams upgrading memory in validated SuperMicro configurations use this part number for guaranteed compatibility.

Sustained load behaviour

Modules operate at 1.10V with CL46 timings across all ranks during continuous operation. Registered buffering reduces electrical stress on the memory controller when all slots are populated. Major OEM Samsung, Micron or Hynix DRAM chips are stress tested under load before shipment to verify stability in 24/7 server environments. The absence of heat spreaders relies on chassis airflow to maintain safe temperatures during extended compute tasks.

Decisive specification

DDR5 5600 RDIMM with ECC and registered buffering is the single requirement that determines fitment in the target SuperMicro platform. UDIMM, LRDIMM or non-ECC variants will not function in this registered-only memory architecture. The 288-pin DDR5 form factor and 2Rx4 rank structure must match the motherboard's qualified vendor list exactly. Systems requiring different speeds, voltages or rank configurations need a separate part number.

Questions about this item

How much heat and power will the 1.1 V DDR5 5600 modules draw when the server runs all day?

Each 64 GB RDIMM operates at 1.10 V with no heat spreader, so sustained load will produce moderate warmth typical for registered DDR5; ensure the chassis airflow matches the SuperMicro B13SEE-CPU-25G thermal design.

What must the motherboard already provide for this 288-pin ECC RDIMM kit to function?

The board needs DDR5 RDIMM slots that support registered ECC memory at 5600 MT/s (PC5-44800) and a BIOS that recognises 2Rx4 organisation; the SuperMicro B13SEE-CPU-25G meets those requirements.

Will the CL46 5600 MT/s kit run stably alongside slower DDR5 DIMMs I might keep in the same system?

The motherboard will clock all installed DDR5 to the lowest common speed and latency, so older 4800 MT/s modules will force this kit to run at 4800 MT/s with relaxed timings.
