16GB DDR4 2133MHz SODIMM for HP ProOne 400 G2 AiO

This 16GB module uses 260-pin DDR4 SO-DIMM technology running at 2133MHz with CL15 timings. It is built specifically for HP ProOne 400 G2 Series All-in-One desktops. The stick operates at 1.2V and is unbuffered non-ECC memory.

Suits owners of listed HP AiO models needing

Buyers whose ProOne 400 G2 AiO already has two populated slots cannot add this module. Systems requiring ECC or registered memory should look elsewhere. The single 16GB stick fills one of two available sockets.

Verify your ProOne 400 G2 model number matches

Check that your unit uses DDR4 SO-DIMM slots and supports 2133MHz speed. Confirm an empty 260-pin slot is available before ordering. The system maximum is 32GB across two sockets.

Questions about this item

Will this 16GB DDR4 2133MHz SODIMM fit alongside an existing 8GB stick in my HP ProOne 400 G2 AiO?

Yes, the ProOne 400 G2 AiO has two SODIMM sockets and supports up to 32GB total, so a 16GB module will work with your existing stick.

Does the CL15 timing on this module match the original memory in an HP ProOne 400 G2 AiO?

The module runs at CL15 15-15-15 timing at 2133MHz, which matches the standard DDR4-2133 specification used in the ProOne 400 G2 AiO.

How can I verify the 16GB DDR4 2133MHz module is recognised at full speed after installation?

Open Task Manager > Performance > Memory and confirm 16GB shows at 2133MHz, or run CPU-Z to see the SPD tab report DDR4-2133 CL15.
