Compatible HP Z Workstations

This 16 GB DDR3 registered DIMM is built for HP Z420, Z620 and Z820 workstations. It delivers ECC error correction and registered signalling for stable operation in professional environments. The module runs at 1600 MHz with a CL11 latency and 1.5 V power draw. It installs in a standard 240-pin DDR3 slot.

Who this suits and who it does not

The part suits owners of the listed Z-series workstations who need a single 16 GB upgrade with ECC registered memory. It will not work in systems that require unbuffered DDR3 modules or a different pin count. Mixing with ECC unbuffered DIMMs is not supported. Builders needing a different capacity or voltage should verify their platform requirements.

Deciding specification

The module uses a 2Rx4 organisation with registered ECC DDR3 at 1600 MHz. This rank and buffer combination determines whether the workstation recognises the memory and runs it at the correct speed. Confirm that your system accepts registered 2Rx4 RDIMMs before ordering.

Questions about this item

What is included in the box and do I need to buy anything else to install this module?

The box contains one 16GB DDR3 1600MHz RDIMM ECC module (part NE-MS-0093). No extra parts are required; the module plugs directly into a free 240-pin DIMM slot on a compatible HP Z420, Z620 or Z820 workstation.

Should I choose this 16GB 2Rx4 RDIMM or a different capacity or rank for my Z420, Z620 or Z820?

This module is a single 16GB 2Rx4 registered ECC DIMM. Select it when you need one 16GB stick; add a second identical module to run dual-channel, or choose 8GB modules if you prefer more sticks for the same total capacity.

What does the 1600MHz PC3-12800 rating mean once the module is running in my workstation?

The module operates at 1600MHz with CL11 latency at 1.5V. If mixed with slower DDR3, the system will run at the speed of the slowest installed module, so all slots should ideally use 1600MHz RDIMMs for full performance.
