Targeted Workstation Upgrade

This 16GB DDR3 ECC Registered RDIMM is built specifically for the HP Workstation Z800. It operates at 1333 MHz with CL9 latency and 1.5V power. The module uses a 2Rx4 rank configuration and a 240-pin form factor. It is designed for server and workstation environments that require error-correcting registered memory.

Compliance And Reliability Focus

The module meets JEDEC and ROHS standards for a warranty-safe installation. OWC tests every unit in-house to ensure it meets or exceeds OEM specifications. The design prevents mixing with unbuffered memory, protecting system stability. This single 16GB stick allows precise capacity scaling for supported configurations.

Platform And Population Checks

Verify that your Z800 workstation supports DDR3 1333 Registered ECC DIMMs before ordering. This memory will not function in standard desktop computers or alongside unbuffered modules. Confirm available 240-pin slots and maximum supported capacity per channel. Matching capacity, speed, and manufacturer across all populated slots is recommended for optimal performance.

Questions about this item

Will this 16 GB DDR3 1333 RDIMM need replacement during the life of my HP Z800?

This module is a solid-state component with no moving parts and no scheduled replacement interval; it only needs to be swapped if a memory test reports a hard error on the 16 GB DIMM.

What is the first limit I will hit when running this ECC Registered memory continuously in the Z800?

The DDR3 1333 bus and CL9 latency set the sustained bandwidth ceiling; the memory controller will throttle before the 1.5 V supply or the 2Rx4 organisation becomes a bottleneck.

How much heat and noise does this 240-pin RDIMM add when the workstation runs all day?

The module has no heat spreader and draws 1.5 V at DDR3 1333 speeds, so it contributes minimal thermal load and zero acoustic noise; system fans will dominate both metrics.
