Server-grade 32 GB DDR4 module

This 32 GB DDR4 2400 MHz ECC registered RDIMM targets administrators upgrading servers, workstations or NAS systems that require registered memory with error correction. The module matches Kingston part numbers KTH-PL424/32G and KTD-PE424/32G for direct replacement. It will not work in standard desktop computers and cannot be mixed with unbuffered modules.

Sustained load behaviour

Operating at 1.2 V with CL17 latency, the dual-rank 2Rx4 design maintains data integrity through ECC correction during continuous workloads. JEDEC compliance and 100 % factory testing ensure stable operation across extended uptime periods typical of server environments.

Compatibility checks

Verify that your platform supports 288-pin DDR4 registered DIMMs and accepts 32 GB per slot before ordering. Confirm the system requires ECC registered memory rather than unbuffered or load-reduced types. Ensure the memory controller can address the full module capacity without population limits.

Questions about this item

Does the 1.2V 2400MHz ECC registered RDIMM run cooler than higher-voltage modules during continuous operation?

Operating at 1.2V, this DDR4 2400MHz ECC registered module draws less power per stick than higher-voltage server memory, reducing heat output during all-day workloads.

What motherboard slot and memory controller features are required for this 288-pin 2Rx4 ECC RDIMM?

The module needs a 288-pin DDR4 slot with ECC and registered-buffer support; it will not work in standard desktop boards that only accept unbuffered non-ECC DIMMs.

Will this PC4-19200 CL17 stick down-clock automatically if installed beside slower DDR4 ECC RDIMMs in the same server?

Yes, the module follows JEDEC DDR4 standards and will run at the lowest common speed and timing when mixed with slower ECC registered DIMMs in the same system.
