Green circuit board DDR5 memory module with black chips and gold contacts

Kingston Technology Corp.

Kingston Technology Corp. KTH-PL556D8-32G 32 GB DDR5 5600 MHz CL46 ECC Registered 288-pin DIMM server RAM

SKU CH-A04H-HVYTP MPN KTH-PL556D8-32G

32 GB DDR5 server memory module running at 5600 MHz with CL46 latency, ECC error correction and registered signal processing on a 288-pin DIMM

  • 32 GB DDR5 capacity supports large server workloads
  • 5600 MHz DDR5-5600 speed enables fast data throughput
  • CL46 CAS latency provides responsive memory access
  • ECC registered design protects data integrity in critical tasks
  • 288-pin DIMM at 1.10 V fits standard server slots

Server Memory Module

This 32 GB DDR5 DIMM is built for servers and workstations that require registered ECC memory. It operates at 5600 MHz with a CAS latency of CL46 and runs at 1.10 V. The dual-rank design fits standard 288-pin slots in compatible enterprise platforms.

Registered ECC Signal Processing

Registered buffering reduces electrical load on the memory controller, allowing larger memory populations in multi-socket systems. On-die ECC detects and corrects single-bit errors to protect data integrity in critical workloads. These features change how the module behaves under sustained server loads compared to unbuffered alternatives.

32 GB Capacity at DDR5-5600

The module provides 32 GB of addressable memory per slot at the PC5-44800 standard. It handles virtualisation hosts, database buffers and large dataset processing within that limit. Workloads requiring more capacity per channel or higher frequencies than 5600 MHz will need different modules.

Questions about this item

Will the dual-rank 32 GB DDR5 module need any firmware updates or periodic reseating in a registered ECC server?

No firmware updates or scheduled reseating are required; the registered ECC design handles error correction and signal integrity automatically once installed in a compatible 288-pin slot.

What thermal or bandwidth limit appears first when the stick runs at 5600 MHz CL46 continuously?

The module is rated for 5600 MHz at 1.10 V with CL46 latency; sustained throughput is capped by the DDR5-5600/PC5-44800 interface before any thermal throttle engages.

How much noise, heat and power does the 1.10 V registered DIMM produce in all-day operation?

The DIMM operates silently with no moving parts; at 1.10 V it draws low power and generates minimal heat, relying on chassis airflow for cooling.
