HP Z2 G4 SFF DDR4 Upgrade

This 8GB DDR4 module is built specifically for the HP Z2 Workstation G4 SFF. It delivers a straightforward capacity increase for professionals needing smoother multitasking and faster application response in a compact workstation form factor.

DDR4 2666 CL19 Limits

The module runs at 2666MHz with CL19 latency at 1.2V, adhering to JEDEC PC4-21300 specifications. It is backward compatible with 2133MHz and 2400MHz bus speeds, so it will downclock automatically if the system memory controller requires a lower frequency.

Verify Slot Count And Config

Confirm your HP Z2 G4 SFF has an available 288-pin UDIMM slot and supports non-ECC unbuffered memory. The workstation uses a small form factor board, so ensure the single-rank 1Rx8 design matches the supported population rules for your current memory configuration.

Questions about this item

Should I choose the 8GB module or look for a different capacity for my HP Z2 G4 SFF?

This module provides 8GB of DDR4 memory; add one or more sticks to reach the total capacity your workload requires.

What does the 2666MHz rating mean once the RAM is installed in the workstation?

The memory runs at 2666MHz with CL19 latency, and will downclock to 2400MHz or 2133MHz if the system bus requires it.

Is the 288-pin UDIMM interface the only factor that determines compatibility?

The stick is a 288-pin DDR4 UDIMM at 1.2V, non-ECC and unbuffered, matching the HP Z2 G4 SFF memory slot specification.
