Capacity and Speed

This Axiom server memory module provides 16GB of capacity and operates at DDR3 1600 (PC3 12800). It is built as a 240-pin RDIMM for systems requiring registered ECC memory.

Target Use Cases

This module suits administrators upgrading compatible HP Gen 8 servers that require registered ECC DDR3 memory. Buyers needing unbuffered UDIMMs or non-ECC memory for workstation or desktop platforms cannot use this part.

Form Factor and Protocol

The memory uses a 240-pin DDR3 interface with registered signal buffering and ECC error correction. Verify that your server platform specifically supports registered DDR3 RDIMMs before purchase.

Questions about this item

Does this 240-pin DDR3-1600 RDIMM need a motherboard slot that accepts registered ECC memory?

Yes, the module is registered and ECC-enabled, so the system must support registered ECC DIMMs in its 240-pin DDR3 slots.

Can I keep this 16 GB Axiom 672631-B21-AX module installed while adding other DDR3 registered DIMMs of different capacities?

The module follows the DDR3-1600 PC3-12800 registered ECC specification; mixing capacities is possible when the platform allows mixed-capacity registered populations.

How can I confirm the 16 GB DDR3-1600 ECC registered stick is recognised at the correct speed after installation?

Check the BIOS or OS memory report — it should show 16 GB at 1600 MHz PC3-12800 with ECC active.
