32GB DDR3 ECC Kit for HP Z800

This OWC upgrade kit supplies 32 GB of DDR3 1333 registered ECC memory in four 8 GB modules. It is built for the HP Workstation Z800 and replaces several original HP part numbers. The modules run at 1.5 V with CL9 latency and a 2Rx4 organisation. They are intended for workstation and server environments that require registered DIMMs.

Compatibility and Limits

The memory fits only systems that accept 240-pin DDR3 registered ECC RDIMMs such as the HP Z800. It will not work in standard desktop computers or any platform that requires unbuffered modules. Mixing these registered sticks with unbuffered memory is not supported. Buyers who need non-ECC or unbuffered memory should look elsewhere.

Registered ECC RDIMM Decides Fit

The single specification that determines whether this kit will work is the registered ECC RDIMM format. Only motherboards designed for registered error-correcting DDR3 DIMMs can use these modules. Verify that your system explicitly supports registered ECC memory before purchasing.

Questions about this item

Will these 240-pin DDR3 modules fit the HP Z800 memory slots?

Yes, the kit uses 240-pin DDR3 1333 registered DIMMs that match the HP Z800 slot layout and 1.5 V requirement.

What is the correct way to populate the four 8 GB sticks in the Z800, and what mistake should I avoid?

Install all four modules in matched-channel pairs as the Z800 manual directs; do not mix these registered DIMMs with any unbuffered memory.

When would the ECC registered DIMMs need replacement in a Z800?

Replace them only if memory diagnostics report correctable or uncorrectable ECC errors, or if a module fails the system POST memory test.
