64GB DDR4 ECC Registered Kit

This 64GB kit contains four 16GB DDR4 2133MHz ECC registered DIMMs built for HP ProLiant DL380p Gen9, DL560 Gen9 and ML350 Gen9 servers. Each module runs at 1.2V with CL15 timing and a 2Rx4 organisation. The registered design adds a buffer that helps maintain signal integrity in high-density configurations.

Verify Slot Count and Part Numbers

Confirm the server has enough free 288-pin DIMM slots; the supported platforms offer 12 sockets per CPU up to 48 sockets with four CPUs installed. Cross-reference the HP part numbers 719061-B21, 719064-B21, 767032-B21, 767033-B21 and 810393-B21 against your service documentation before ordering.

Fits Multi-CPU Memory Expansion

The modules populate standard DDR4 RDIMM slots and work within the platform limit of 1.50TB of registered ECC memory per system. Using registered DIMMs frees the memory controller from driving every load directly, allowing the full 48-socket capacity across four processors without requiring LRDIMMs.

Questions about this item

What comes in the box and is anything else required for installation in a ProLiant DL380p Gen9?

The kit includes four 288-pin DDR4 registered DIMMs. No extra parts are needed; the modules install directly into the server's memory slots.

How do I decide between the listed part numbers such as 719061-B21 and 810393-B21 when ordering?

All listed HP part numbers reference the same 64 GB DDR4-2133 ECC registered specification. Choose the part number that matches your server's service documentation.

Will the 2133 MHz rating run at that speed once installed in a DL560 Gen9?

Yes. The modules operate at DDR4-2133 with CL15 timing at 1.2 V when the server's memory controller is configured for that speed.
