OWC 16GB DDR3 1333 ECC Registered RDIMM 2Rx4 HP ProLiant DL160 G6 DL165 G7 DL170e G6 DL170h G6 DL180 G6

16GB DDR3 ECC RDIMM for HP ProLiant servers

This 16GB DDR3 1333 ECC Registered RDIMM is designed for HP ProLiant DL160 G6, DL165 G7, DL170e G6, DL170h G6 and DL180 G6 servers. It operates at PC3-10600 speed with CL9 latency and 1.5V voltage. The module uses a 2Rx4 rank configuration on a 240-pin form factor without a heat spreader. It targets administrators extending the service life of these specific rackmount platforms.

Upgrade from lower-capacity DDR3 RDIMMs

Replacing smaller registered DIMMs with this 16GB module increases total memory capacity while maintaining ECC error correction and registered signalling required by the listed ProLiant models. The jump is worthwhile when workloads such as virtualisation or database caching exceed the current memory ceiling. Mixing with unbuffered memory is not supported, so all slots must use registered modules of matching specification.

Verify registered DIMM slots and population rules

Before ordering, confirm the server has available 240-pin DDR3 slots that accept registered ECC memory and check the system documentation for maximum supported capacity per slot and per channel. Ensure existing installed modules are also registered ECC types; mixing registered with unbuffered memory will prevent boot. The platform must support 2Rx4 organisation at 1333 MT/s.
