HP Gen8 DDR3 ECC RDIMM upgrade

This Axiom 672633-B21-AX module adds 16GB of DDR3-1600 registered ECC memory to supported HP ProLiant servers. It is built for administrators expanding capacity in Gen8 and G7 blade or rack platforms that require registered DIMMs with error correction.

Suited for HP ProLiant Gen8 and G7 servers

The module fits ProLiant BL465c G7, BL465c Gen8, BL685c G7, DL385 G7, DL385p Gen8 and DL585 G7 systems. It is not for workstations or desktops that accept only unbuffered non-ECC DDR3, nor for platforms that require a different pin count or voltage.

240-pin DDR3-1600 registered ECC specification

The single specification that decides fit is the 240-pin DDR3-1600 registered ECC standard (PC3-12800). Only systems designed for this exact combination of pin layout, speed, registration and error checking will recognise and use the module.

Questions about this item

Should I choose the 16GB DDR3-1600 ECC Registered RDIMM or a different capacity for my HP ProLiant Gen8 server?

This module provides 16GB per DIMM at DDR3 1600 (PC3 12800) with ECC and registered signal processing, matching the listed HP ProLiant BL465c Gen8, DL385p Gen8 and other G7/G8 systems.

What does the DDR3 1600 (PC3 12800) speed rating deliver once installed in a ProLiant BL465c Gen8?

The module runs at 1600 MHz, providing a peak transfer rate of 12800 MB/s per channel; actual throughput depends on the server's memory controller configuration and populated DIMM slots.

How does the 240-pin DDR3 RDIMM interface limit maximum memory capacity in a DL385p Gen8?

The 240-pin DDR3 registered DIMM form factor fits the Gen8 memory slots; total system capacity is capped by the number of available slots and the processor's supported memory channels, not by the module interface itself.
