HPE Server 32GB DDR4 RDIMM

This 32GB DDR4 3200 ECC registered DIMM is built for HPE servers and workstations that require registered memory with error correction. It operates at 1.2V with CL22 latency and a 2Rx4 organisation. The module uses major OEM chips and fits 288-pin DDR4 slots.

Replacing slower or smaller DDR4 modules

The upgrade is worthwhile when the system currently runs below 3200MT/s or has fewer than 32GB per slot and the platform supports registered ECC memory. It will not benefit systems limited to unbuffered DIMMs or lower maximum speeds.

DDR4 registered ECC limits

Registered ECC modules must match the server memory controller and cannot be mixed with unbuffered DIMMs. Maximum capacity and speed depend on the specific HPE model and CPU generation installed.

Questions about this item

Will the 288-pin DDR4 RDIMM fit my HPE server's memory slots?

Yes, this 288-pin DDR4 RDIMM matches the physical slot layout of HPE systems that accept PC4-25600 registered memory.

Do I need to populate specific slots first when installing this 2Rx4 module?

Install the module in the lowest-numbered slot of the correct channel as shown in your server's service guide; the common mistake is skipping the first slot in a channel.

How can I tell if this ECC RDIMM needs replacement later?

The module runs at 1.20 V with CL22 latency; persistent corrected ECC errors logged by the BIOS or OS indicate the DRAM should be swapped.
