16 GB DDR4 2400 ECC RDIMM

This 16 GB DDR4 2400 registered DIMM targets servers and workstations that require error-correcting memory. It operates at 1.20 V with CL17 latency and a 2Rx4 organisation. The 288-pin module replaces Kingston KVR24R17D4/16I and KTH-PL424/16G equivalents.

Registered ECC limits

Registered ECC modules add a register between the memory controller and the DRAM chips, which reduces electrical load but introduces one extra clock cycle of latency. Systems must support registered DIMMs and ECC functionality; standard desktop platforms without chipset support will not boot with this module.

2Rx4 rank configuration

The dual-rank 2Rx4 layout determines how the memory controller addresses the chips and affects maximum population rules on many server boards. Verify that your platform accepts 2Rx4 registered DIMMs at DDR4 2400 before purchasing.

Questions about this item

Should I choose a 16GB DDR4 2400 ECC RDIMM CL17 2Rx4 module or a different capacity for my server?

This module provides 16GB in a single 288-pin DDR4 DIMM running at 2400MHz with CL17 latency and 2Rx4 organisation. Add identical modules to fill your board's channels for maximum bandwidth.

What does the 2400MHz PC4-19200 rating mean once the module is installed in a real server?

The module transfers data at 2400MT/s, delivering up to 19200MB/s theoretical bandwidth per channel. Actual throughput depends on your CPU's memory controller, channel population and BIOS settings.

How does the DDR4 288-pin RDIMM interface affect what speed and capacity the system can use?

The registered 288-pin DDR4 DIMM presents a controlled electrical load to the memory controller, allowing larger capacities per channel. The board's chipset and CPU still dictate the maximum supported frequency and total memory limit.
