Server-grade ECC RDIMM

This 64GB DDR4 3200 module is a registered ECC DIMM built for HP ProLiant DL110 Gen10 Plus Telco and DL325 Gen10 Plus servers. It delivers 2Rx4 organisation at CL22 latency and 1.2V operation. The part is designed for workloads that require error-correcting registered memory in those specific platforms.

Fits ProLiant DL110 and DL325

The 288-pin RDIMM installs directly into the memory slots of the listed ProLiant models without adapters. It requires a server motherboard that supports registered ECC DDR4 and cannot be used with unbuffered or load-reduced DIMMs. Mixing with other memory types is not supported by the platform.

Replaces HP P43170-B21 and related

This module replaces HP part numbers P43170-B21, P06035-B21, P06035-H21, P07650-B21, P07650-H21, P07650-K21 and P25205-B21. The upgrade is worthwhile when expanding capacity beyond the factory configuration or when a failed DIMM must be swapped with a validated equivalent. It is not for desktop PCs or systems that accept only unbuffered memory.

Questions about this item

What is the CAS latency that governs timing under sustained load?

The module runs at CL22, which sets the latency floor when the server is under continuous demand.

How much power does a 1.2 V registered DIMM draw during all-day operation?

At 1.2 V the stick stays within standard DDR4 registered power limits, keeping heat output low enough for dense ProLiant chassis airflow.

Which HP ProLiant models must the buyer already own for this upgrade to work?

This 64 GB DDR4 3200 RDIMM is validated for HP ProLiant DL110 Gen10 Plus Telco and DL325 Gen10 Plus servers.
