Server memory kit

This OWC kit supplies 32GB of DDR3 ECC registered memory across four 8GB modules. It targets administrators upgrading HP ProLiant blade servers that require registered DIMMs with error correction. The modules will not work in standard desktop platforms or alongside unbuffered memory.

240-pin registered DIMMs

Each stick uses a 240-pin DDR3 interface at 1.5V with CL9 latency and a 2Rx4 organisation. The registered design adds a buffer that reduces electrical load on the server memory controller, allowing the full kit to populate compatible blade slots without signal integrity issues. No heat spreaders are fitted, so airflow in the chassis handles cooling.

HP part-number match

The kit replaces HP part numbers including 500205071, 500205171, 500206071, 500662B21, 501536001, 593913B21, A0R56A, FX622AA and FX622UT. Buyers can therefore order by the familiar HP references and receive a direct drop-in upgrade. Builders needing unbuffered memory or higher speeds must look elsewhere.

Questions about this item

Does DDR3 1333 PC3-10600 limit bandwidth on HP ProLiant Gen7 blades?

The kit runs at 1333 MT/s with CL9 timing, matching the maximum DDR3 speed the BL460c G7, BL490c G7, BL620c Gen7, BL680c Gen7 and BL685c Gen7 memory controllers support.

Will the 240-pin 2Rx4 registered DIMMs fit the HP ProLiant BL460c G7 memory slots?

Yes, each 8 GB module uses the standard 240-pin DDR3 RDIMM form factor with 2Rx4 organisation, which is the exact layout required by the listed ProLiant blade servers.

How do I install the four 8 GB ECC registered modules in a BL680c Gen7, and what step is often missed?

Populate all four modules in matched channel pairs per the server’s memory population guide, then enable ECC in the BIOS — skipping the BIOS step leaves error correction inactive.
