32GB DDR5 Registered ECC Module

This 32GB DDR5 module operates at 4800 MHz with CL40 latency and a 1.10V voltage. It uses a 288-pin DIMM form factor with a 1Rx4 registered design. The KTH-PL548S4-32G is built for workstations and servers that require error-correcting code memory for data integrity.

Registered Signal and ECC Support

Registered signal processing reduces electrical load on the memory controller to support stable operation in high-density configurations. On-die ECC corrects single-bit errors to maintain data accuracy during heavy workloads. The single-rank layout allows this 32GB capacity to fit within standard channel population rules.

DDR5 4800 Platform Constraints

DDR5 4800 speed is only achieved when the processor and motherboard officially support this data rate. Registered DIMMs cannot be used in consumer desktop boards that lack buffered memory support. ECC functionality requires a compatible CPU and chipset; without them the module will not provide error correction.

Questions about this item

How often should the 288-pin DDR5 module be reseated or replaced under normal server workloads?

Registered ECC DDR5 modules like this 32 GB stick have no scheduled reseating or replacement interval; they are designed to run continuously for the life of the platform.

What is the first limit reached when the 4800 MHz CL40 memory runs at full load for extended periods?

The JEDEC-defined 1.10 V operating voltage and CL40 timing are the primary electrical limits; the registered buffer maintains signal integrity up to the rated 4800 MT/s data rate.

How much heat and power does the 1Rx4 registered DIMM produce when the system runs all day?

At the specified 1.10 V the module draws only the power required for 4800 MT/s operation; registered buffering and on-die ECC keep thermal output low enough for standard server airflow.
