32 GB DDR4-2400 ECC registered RDIMM with CL15 latency and 1.2 V operation for HP-compatible servers
This 32GB DDR4-2400 module is built for servers that require error-correcting, registered memory. It suits administrators expanding capacity in compatible HP platforms or similar enterprise systems. The 2Rx4 organisation and CL15 latency support stable operation under sustained workloads.
The 288-pin RDIMM installs directly into registered DDR4 DIMM slots on supported server boards. Registered buffering reduces electrical load on the memory controller, allowing higher total capacities across populated channels. ECC functionality corrects single-bit errors to protect data integrity in critical applications.
Upgrading from smaller RDIMMs or unbuffered memory adds 32GB per slot and enables ECC protection where the platform supports it. The jump is worth it when virtualisation density, database caching or compute-node stability demand maximum registered capacity per channel. Not for systems limited to unbuffered UDIMMs or speeds above DDR4-2400.

This RDIMM is organised as 2Rx4, presenting two ranks per module so the server can interleave accesses across both ranks for higher sustained bandwidth.
It operates at the standard DDR4 voltage of 1.20V, keeping power draw and thermal output low enough for dense server configurations with restricted airflow.
The module requires a 288-pin DDR4 RDIMM slot with registered ECC support; the platform must accept registered, error-correcting DIMMs to initialise correctly.
