HP ProLiant Server Memory

This 16 GB DDR3 1600 module is built for HP and Compaq ProLiant servers that require registered ECC memory. It operates at 1.50 V and uses a 240-pin form factor with a 2Rx4 rank configuration. The part matches HP part numbers 672631-B21 and 684066-B21 for direct replacement.

Suited for ProLiant upgrades

Administrators expanding memory in compatible HP ProLiant systems will find this module fits the validated configuration. Builders working on consumer desktops, workstations or non-HP servers should look elsewhere because the registered ECC design and system-specific qualification prevent use in standard unbuffered platforms.

Registered ECC qualification

The single specification that decides fit is the registered ECC DDR3 1600 rating combined with HP ProLiant validation. Only systems that explicitly support registered ECC modules at this speed and rank will accept the part.

Questions about this item

Will the 16GB DDR3 1600 registered ECC module run in an HP ProLiant server that already has 8GB registered ECC DIMMs installed?

Yes, provided the server supports DDR3 1600 registered ECC memory and the existing DIMMs are also 1.50V registered ECC; mixing capacities is supported on compatible HP/Compaq platforms listed under part numbers 672631-B21 and 684066-B21.

How can I verify the 2Rx4 registered ECC module is detected and running at DDR3 1600 after installation?

Check the system BIOS or iLO interface during POST — it should show 16GB total capacity, registered ECC mode enabled, and a memory speed of 1600 MT/s for the new DIMM.

Does the KTH-PL316/16G package include a heat spreader or any installation tools, or must those be purchased separately?

The module ships as a bare 240-pin DDR3 SDRAM DIMM; no heat spreader, tools, or additional accessories are included in the box.
