OWC 16GB DDR3L ECC RDIMM Kit

This 16 GB kit contains two 8 GB DDR3L 1600 registered DIMMs built for HP ProLiant BL465c G7 and DL980 G7 servers. It operates at 1.35 V with CL11 latency and includes on-die ECC for data integrity. The modules are not compatible with standard desktop systems or unbuffered memory configurations.

Registered ECC with 1Rx4 Organisation

The single specification that determines fit is the registered ECC RDIMM design with 1Rx4 rank structure. This module type is required by the target ProLiant platforms and will not work in systems that accept only unbuffered UDIMMs or a different rank layout. Mixing with non-registered memory is not supported.

Sustained Server Workload Behaviour

Under continuous load the DDR3L 1600 modules maintain JEDEC-compliant timing at 1.35 V without a heat spreader. The registered buffer reduces electrical loading on the memory controller, allowing stable operation during extended virtualization or database tasks. Error-correcting code corrects single-bit errors in real time to prevent data corruption.

Questions about this item

How does the 1600 MHz speed translate once the kit is installed in a ProLiant BL465c G7 or DL980 G7?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 timing, delivering the rated throughput as long as the server's memory controller supports that frequency.

What does the 240-pin DDR3L registered ECC interface limit in practice?

The registered ECC design only works in workstation or server boards that accept 240-pin DDR3L RDIMMs; it cannot be used in standard desktop or unbuffered memory slots.

What physical clearance does the 240-pin RDIMM need to fit in the target HP servers?

Each module is a standard-height 240-pin DDR3L RDIMM without a heat spreader, so it fits the regular DIMM sockets in the BL465c G7 and DL980 G7.
