HPE 64 GB DDR4 RDIMM Server Memory

This HPE P06035-B21 module provides 64 GB of DDR4 registered ECC memory in a single RDIMM. It operates at PC4-25600 bus speed for compatible HPE server platforms. The 2RX4 organisation supports high-density configurations. It is designed for enterprise workloads that require data integrity and maximum capacity per slot.

Suited for HPE servers needing registered ECC DIMMs

This module fits HPE systems that accept PC4-25600 registered RDIMMs with ECC. It is not for desktop PCs, laptops or workstations that use unbuffered non-ECC memory. Buyers who need unregistered DIMMs or lower-voltage SO-DIMMs should look at a different product line.

Verify your server model supports 64 GB registered

Check the system documentation for maximum DIMM capacity per slot and qualified speed at PC4-25600. Confirm the memory population rules for 2RX4 modules on your specific HPE platform. Ensure the firmware revision lists this part number as supported before installation.
