Compatible 16 GB DDR4 SODIMM for HP Z1 G3

This 16 GB DDR4 2133 MHz CL15 SODIMM is built specifically for the HP Z1 Workstation G3. It runs at 1.2 V as an unbuffered non-ECC module with a 2Rx8 rank layout and no heat spreader. The part number is 2S1D42R816GB and it meets JEDEC PC4-17000 specifications.

Check your HP Z1 G3 memory slots before ordering

The system uses 260-pin DDR4 SODIMM slots and requires non-ECC unbuffered memory at 1.2 V. Verify how many slots are free and whether the board can address a 2Rx8 16 GB module. The upgrade is a straightforward DIY install but only fits the G3 workstation model.

Steady throughput under continuous workloads

Rated at DDR4 2133 with CL15 latency, the module maintains its JEDEC timings during extended sessions. Without a heat spreader it relies on case airflow, so sustained multitasking or large-file work stays stable as long as the chassis cooling is adequate. The 2Rx8 organisation helps keep bandwidth consistent over time.

Questions about this item

Does the module come as a single 16 GB stick or do I need to buy a second one for dual-channel?

This is a single 16 GB SODIMM. Adding a second identical module will enable dual-channel operation on the Z1 G3.

Is the CL15 2133 MHz variant the only one qualified for the Z1 G3?

The 2133 MHz CL15 1.2 V specification matches the HP Z1 Workstation G3 memory requirement.

What does the 2133 MHz rating actually deliver inside the Z1 G3?

The module runs at 2133 MT/s with CL15 latency at 1.2 V, providing the standard DDR4 bandwidth the workstation expects.
