16GB DDR3-1600 ECC RDIMM Server Memory

This is a 16GB DDR3 1600MHz registered ECC DIMM built for server and workstation platforms. It operates at the standard 1.5V DDR3 voltage with CL11 latency and a 2Rx4 organisation. The module uses major-brand chips and carries a 240-pin form factor.

Suits HP part-number matches.

The module replaces the listed HP part numbers including 672309-581, 672612-081 and 684031-001. It is intended for systems that require registered ECC DDR3 memory. It will not work in platforms that only accept unbuffered non-ECC DIMMs.

Registered ECC DDR3 with 2Rx4 organisation

The single specification that determines fit is the registered ECC DDR3 interface combined with a 2Rx4 rank structure. Your motherboard must explicitly support registered ECC DDR3 DIMMs of this organisation for the module to function.
