Server-grade DDR5 capacity

This 32 GB DDR5 registered DIMM delivers ECC-protected memory for server workloads that demand data integrity. It operates at 5600 MHz with a CL46 latency and runs at 1.10 V. The module uses a 288-pin form factor and is organised as dual-rank.

Platform compatibility check

Verify that your motherboard supports DDR5 RDIMM modules with ECC and registered signal processing before ordering. The system must accept 288-pin DIMMs at the PC5-44800 standard. Confirm the maximum capacity per slot and the total number of populated channels your platform allows.

Thermals and power profile

Without a heat spreader, the module relies on chassis airflow for cooling during sustained server operation. The low 1.10 V operating voltage helps contain power draw under typical multi-channel loads. Acoustic output is determined by the system fans rather than the memory itself.

Questions about this item

Does the KTD-PE556D8-32G arrive as a single 32 GB DDR5 RDIMM or must extra modules be purchased to reach that capacity?

The module is a single 32 GB DDR5 5600 RDIMM with ECC and registered signal processing; no additional parts are required for that capacity.

When should I choose this dual-rank CL46 5600 MHz stick over a single-rank or lower-latency alternative?

Dual-rank organisation suits servers that benefit from higher density per channel, while CL46 at 5600 MHz matches the standard JEDEC timing for DDR5-5600 registered ECC memory.

What does the 5600 MHz rating deliver once the DIMM is installed in a compatible server platform?

The module runs at the JEDEC-standard 5600 MT/s data rate (PC5-44800) at 1.10 V with ECC and registered buffering active.
