OWC 64GB DDR3 ECC Registered Kit

This OWC kit supplies 64GB of DDR3 1333 PC3-10600 CL9 ECC Registered RDIMM memory in four 16GB modules. Each 240-pin DIMM operates at 1.5V with a 2Rx4 rank structure and no heat spreader. The kit is built for HP ProLiant DL360 G7, DL370 G6, DL380 G7, DL385 G7 and DL580 G7 servers.

Suits HP ProLiant G6 and G7 servers

It fits administrators expanding memory in the listed ProLiant models where registered ECC DDR3 is required. It will not work in standard desktop computers or any system that accepts only unbuffered non-ECC modules. Buyers needing unbuffered memory or a different DDR generation should look elsewhere.

Check server model and memory rules

Verify the exact ProLiant model matches one of the five listed part numbers before ordering. Confirm the platform requires registered ECC RDIMMs and does not mix registered with unbuffered DIMMs. Ensure all slots can accept 16GB 2Rx4 modules at DDR3 1333 speed.

Questions about this item

Which servers must I already own to install this 64GB kit?

It is validated for HP ProLiant DL360 G7, DL370 G6, DL380 G7, DL385 G7 and DL580 G7 systems.

Can I keep my existing unbuffered DDR3 DIMMs alongside these registered modules?

No, the manufacturer states registered ECC memory cannot be mixed with unbuffered memory.

How do I confirm the kit is running at the rated 1333 speed after installation?

Check the BIOS or server management console; it should report DDR3 1333 (PC3-10600) CL9 at 1.5V.
