HP ProLiant Gen7 Server Memory Kit

This OWC kit delivers 64 GB of DDR3 1333 ECC registered memory in two 32 GB modules. It is built for HP ProLiant BL460c G7, BL490c G7, BL620c Gen7, BL680c Gen7 and BL685c Gen7 blade servers. The modules run at 1.5 V with CL9 latency and a 4Rx4 organisation. They are designed to extend the service life of these specific enterprise platforms.

Suited for Gen7 blade upgrades, not desktops

The kit targets administrators upgrading compatible HP ProLiant Gen7 blades that require registered ECC DDR3 DIMMs. It is not for standard desktop computers or workstations that accept only unbuffered non-ECC memory. Buyers whose systems demand a different DDR generation, a different voltage or a different pin count should look elsewhere. Mixing these registered modules with unbuffered DIMMs is not supported.

Registered ECC DDR3 1333 240-pin DIMM

The single specification that decides fit is the registered ECC DDR3 1333 240-pin form factor with 4Rx4 ranking. Only systems that explicitly support this exact combination will operate correctly. Verify the server memory-qualified vendor list before purchase.

Questions about this item

What modules are included in the 64 GB kit and is anything else required?

The kit contains two 32 GB DDR3 1333 ECC registered RDIMMs. No extra parts are needed for the listed HP ProLiant servers.

Should I choose this 64 GB kit or a different capacity for my BL460c G7?

This kit provides the maximum 64 GB using two 32 GB modules. Select a smaller kit only if your workload needs less memory or your budget requires it.

What does the PC3-10600 rating mean once the memory is installed in a ProLiant BL680c Gen7?

PC3-10600 indicates DDR3 1333 MT/s bandwidth. The server will run the modules at that speed with CL9 latency and ECC error correction active.
