32 GB DDR5-5600 Registered ECC DIMM

This 32 GB DDR5-5600 module is a registered ECC DIMM built for servers and workstations that require error-correcting memory. The single-rank 1Rx4 organisation and CL46 timing suit multi-socket platforms where stability outweighs raw latency. It is not for desktop boards that accept only unbuffered non-ECC memory.

Registered signal and on-die ECC

Registered signalling reduces electrical load on the memory bus, while on-die ECC and x80 ECC with two independent I/O sub-channels correct single-bit errors inside the DRAM before data leaves the module. Hard and soft post-package repair plus sideband I3C/I2C access give the platform firmware extra tools for health monitoring and recovery.

DDR5-5600 CL46 at 1.10 V

The module runs at 5600 MT/s with 46-45-45 timings at 1.10 V, delivering PC5-44800 bandwidth in a 288-pin RDIMM form factor. That speed and voltage combination is the decisive spec: the motherboard and CPU memory controller must both support DDR5-5600 registered operation at this voltage for the DIMM to function.

Questions about this item

Will this 288-pin DDR5 RDIMM need a heat spreader added later?

The module ships without a heat spreader; its 1.10 V operating voltage and 31.25 mm height fit standard server airflow, so no retrofit is required.

What limit appears first when this 5600 MHz CL46 module runs sustained workloads?

The registered buffer and CL46 latency set the throughput ceiling before thermal or power limits are reached.

How much power and heat does this 288-pin DDR5 RDIMM produce when running all day at 1.10 V?

At 1.10 V typical VDD and VDDQ the module draws low power per DIMM; server chassis airflow handles the resulting heat without extra cooling.
