HP Z1 Workstation memory upgrade

This 16GB DDR4 3200MHz CL22 UDIMM is built for HP Z1 Workstation G6, G8, G5 SFF, G5 Tower and G8 SFF systems. It runs at 1.2V with a 2Rx8 rank layout and no heat spreader. The module meets JEDEC PC4-25600 specifications and is backed by a limited lifetime warranty with free technical support.

Suitable for owners of listed HP Z1 models adding

Buyers who need ECC error correction or registered modules for server platforms should look elsewhere. Systems requiring speeds above 3200MHz or a different form factor will not accept this DIMM.

Simple DIY installation in most cases

Align the notch with the 288-pin slot and press until the latches click. Common issues include mixing speeds that force the system to run at the lowest common rate and failing to seat the module fully, which prevents the machine from posting.

Questions about this item

Does the HP Z1 Workstation need a free 288-pin DDR4 UDIMM slot for this 16GB module?

Yes, the module is a 288-pin DDR4 Non-ECC UDIMM and requires an available DDR4 UDIMM slot on the motherboard.

Will this DDR4 3200MHz CL22 stick run at its rated speed alongside older 2133MHz DDR4 modules?

The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz DDR4, so it will downclock to match the slowest installed module.

How can I confirm the 16GB DDR4 3200MHz module is recognised at the correct speed after installation?

Enter the system BIOS or use a tool such as CPU-Z to verify the memory shows 16GB capacity and a 3200MHz data rate with CL22 timings.
