64GB DDR4 3200 ECC RDIMM for Servers

This 64GB DDR4 3200MHz module is a registered ECC DIMM built for server and workstation platforms that require error-correcting memory. It operates at the standard DDR4 voltage of 1.20V with CL22 latency and a 2Rx4 rank configuration. The 288-pin form factor fits DDR4 DIMM slots in compatible enterprise systems.

Check System Requirements Before Ordering

Verify that your motherboard supports DDR4 registered ECC memory and accepts 64GB single-rank or dual-rank modules at 3200MHz. Confirm the maximum capacity per slot and the total memory limit for your specific server model. Ensure the BIOS is updated to recognise this module density and speed grade.

Replaces HP P06035-B21 and Compatible Part Numbers

This module serves as a direct replacement for HP part numbers including P06035-B21, P07650-B21, P07650-H21, P07650-K21, P11446-0A1 and P11446-1A1. The upgrade is worth it when your current configuration hits capacity limits or runs slower DDR4 speeds, and your platform qualifies these specific part numbers for use.
