OWC 16GB DDR4 2666MHz CL19 1.2V 288-Pin UDIMM HP Z2 G4 SFF

HP Z2 G4 SFF memory upgrade

This 16 GB DDR4 module is built specifically for the HP Z2 Workstation G4 SFF. It uses a 288-pin unbuffered UDIMM form factor and runs at 1.2 V. The kit targets professionals who need a straightforward capacity increase for multitasking and larger project files.

Sustained workload behaviour

Rated at 2666 MHz with CL19 latency, the module operates within standard JEDEC DDR4 timings for stable throughput during long rendering or compilation sessions. Non-ECC unbuffered design keeps latency low for typical workstation applications. Backward compatibility with 2133 MHz and 2400 MHz platforms allows the stick to downclock automatically if the system requires it.

Pre-installation checklist

Verify that your Z2 G4 SFF has a free 288-pin DDR4 slot and that the current BIOS recognises 2666 MHz UDIMMs. The module is a 2Rx8 dual-rank part, so confirm the motherboard supports this rank configuration in the intended slot population. No heat spreader is fitted, so ensure case airflow is adequate for bare PCB operation.
