16GB DDR4 2666MHz UDIMM for HP EliteDesk

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It is a 288-pin non-ECC unbuffered DIMM built to JEDEC standards. The kit is validated for HP EliteDesk 705 G4 Tower, 800 G4 SFF and 800 G4 Tower systems.

Suits owners of listed EliteDesk models needing

Buyers with other desktops, workstations or NAS units should verify 288-pin DDR4 support and maximum module capacity before purchasing. Systems requiring ECC or registered memory cannot use this module. Laptops and small-form-factor boards using SO-DIMM slots are incompatible.

Installation is a standard DIMM seat

Align the notch, press firmly until the retention clips click, then power on. Common issues include not seating the module fully, mixing speeds that force the system to the lowest common speed, or exceeding the motherboard's maximum capacity per slot.

商品問答

Does my HP EliteDesk 800 G4 Tower need a free 288-pin DDR4 slot to install this 16GB module?

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

Will this 2666MHz CL19 module downclock to run alongside my existing 2400MHz DDR4 sticks?

The module is backward compatible with 2133MHz and 2400MHz speeds and will run at the highest common speed supported by all installed modules.

How can I confirm the system recognises the full 16GB capacity after installation?

Check the total installed memory in Windows Task Manager or the BIOS/UEFI setup screen; it should show the new 16GB module added to your existing memory.
