Capacity and registered ECC design

This is a 16GB DDR4 2400 ECC RDIMM module built for server and workstation platforms that require registered memory with error correction. The 2Rx4 organisation and CL17 timing suit systems qualified for PC4-19200 operation at 1.20V. It replaces a long list of IBM-Lenovo part numbers including 00NV204, 01AG609, 01KM880, 01KN356, 01KN358, 46W0829, 46W0831, 4X70G88319 and 4X70M09262.

Sustained workload behaviour

Registered buffering and ECC circuitry maintain data integrity during continuous multi-threaded loads typical of virtualisation, database or compute clusters. The module runs at standard DDR4 voltage so thermal output stays predictable inside densely populated DIMM slots. Quality assurance testing is performed on every unit to verify reliable operation over extended duty cycles.

Compatibility checks before ordering

Confirm that your platform accepts DDR4 RDIMM modules in a 288-pin form factor and supports 2Rx4 registered ECC at 2400 MT/s. Verify the maximum capacity per slot and the total number of populated channels allowed by your specific motherboard or server model. Cross-reference the listed IBM-Lenovo part numbers against your system service manual to ensure the correct rank and voltage match.

Questions about this item

Will the registered ECC design of this 16 GB DDR4 2400 module add noticeable heat or power draw in a server running 24/7?

The module runs at the standard DDR4 voltage of 1.20 V, and registered ECC DIMMs are built for continuous server workloads without extra cooling beyond normal chassis airflow.

What must my system already provide for this 288-pin DDR4 2400 ECC RDIMM to function?

A server or workstation motherboard with DDR4 RDIMM slots that support ECC registered memory at 2400 MHz and 1.20 V operation.

Can I mix this 2Rx4 CL17 stick with other DDR4 2400 registered ECC modules already installed?

Yes, provided the existing modules are also DDR4 2400 ECC RDIMMs; the memory controller will train all sticks to the lowest common speed and latency.
