ECC Registered RDIMM for HP ProLiant G7 Gen7

This 16GB DDR3 1333 PC3-10600 CL9 module uses a 240-pin 1.5V registered design with 2Rx4 organisation. It targets administrators upgrading HP ProLiant BL460c G7, BL490c G7, BL620c Gen7, BL680c Gen7 or BL685c Gen7 servers. The single DIMM adds capacity without requiring a matched pair.

Steady throughput under ECC workloads

Registered buffering and ECC correction keep data integrity intact during continuous multi-threaded tasks such as virtualisation host duties or database caching. The CL9 latency at 1333 MT/s delivers predictable bandwidth for sustained loads rather than short bursts. JEDEC-standard signalling avoids timing drift over long uptimes.

Slot-in install with mixing constraints

The 240-pin form factor seats directly in the compatible blade sockets; no heat spreader means clearance is not a concern. Installation fails if mixed with unbuffered DIMMs or if populated across channels with mismatched ranks. OWC recommends identical capacity, speed and manufacturer per channel for stable operation.

Questions about this item

Does the 1.5V DDR3 module run hot or draw extra power when the server operates continuously?

The module operates at the standard 1.5V DDR3 voltage with no heat spreader, so thermal output matches the JEDEC baseline for registered DIMMs under sustained load.

My HP ProLiant BL460c G7 currently uses unbuffered DIMMs — can I add this registered ECC stick alongside them?

No, registered ECC memory cannot be mixed with unbuffered modules; the system requires all slots to use registered DIMMs of the same type.

Will this 2Rx4 16GB stick work in a BL680c Gen7 that already has 2Rx8 modules installed?

Yes, the BL680c Gen7 supports mixed rank configurations, so a 2Rx4 module can populate a free slot alongside existing 2Rx8 DIMMs.
