HP Z1 Workstation Memory Upgrade

This 16GB DDR4 UDIMM is built for HP Z1 Workstation G5, G4 Core X and G4 Tower models. It targets professionals who need more capacity for multitasking and larger datasets in these specific all-in-one and tower systems.

288-Pin Non-ECC Unbuffered DDR4 2666MHz CL19

The module runs at 2666MHz with PC4-21300 rating and CL19 latency at 1.2V. It is a 2Rx8 dual-rank stick without a heat spreader. JEDEC compliance and backward compatibility with 2133MHz and 2400MHz ensure it will negotiate the correct speed automatically.

Fits Standard UDIMM Slots in Supported Z1 Chassis

Installation uses the existing 288-pin DIMM sockets on the system board. No extra power cables, adapters or BIOS updates are required beyond the standard memory configuration rules for the listed workstations. The upgrade frees the CPU from excessive paging when multiple applications or large files are open.

商品問答

How does the 2666MHz speed behave once installed in my HP Z1 workstation?

The module runs at 2666MHz CL19 when the system supports that speed; if the platform only supports 2133MHz or 2400MHz it will downclock automatically to match.

What does the PC4-21300 rating mean for real-world bandwidth limits?

PC4-21300 is the JEDEC designation for DDR4-2666; the workstation's memory controller and channel configuration determine the actual throughput you observe.

Will this 288-pin UDIMM fit the memory slots in an HP Z1 G5, G4 Core X or G4 Tower?

Yes, the 288-pin unbuffered DIMM form factor matches the slots used in those HP Z1 workstation models.
