Compatible HP Desktops

This 16 GB DDR4 module is built for HP Omen Obelisk 875-0xxx, Pavilion 595-p0039c and Pavilion TP01-xxx systems. It targets owners of those desktops who need a straightforward capacity increase without compatibility guesswork. The stick arrives new and ready to install. Buyers using other motherboards or laptops should look elsewhere.

2666 MHz CL19 Specification

The decisive figure is the DDR4 2666 speed rated at CL19 with 1.20 V operation. If your platform requires a different frequency, latency or voltage this module will not run at its rated settings. The board will down-clock to the slowest installed memory, so matching the existing spec matters. No ECC or registered buffering is present.

Dual-Slot Upgrade Path

The supported desktops provide two DIMM sockets with a 32 GB ceiling. Adding this single 16 GB stick leaves one slot open for a future matched pair. A 64-bit operating system is required to address more than 4 GB. Mixing brands is possible but all memory will operate at the lowest common speed.

Questions about this item

What does the 2666 MHz speed mean once the module is installed in my HP desktop?

The module will run at up to 2666 MHz, but the system will operate all installed memory at the slowest speed among the modules and the processor's memory controller limit.

How does the DDR4 288-pin DIMM interface limit performance in practice?

The DDR4 288-pin DIMM interface supports the module's rated 2666 MHz (PC4-21300) bandwidth; actual throughput is capped by the CPU's memory controller and any slower modules present.

What physical space and slot type does this 16 GB stick need to fit in the Omen Obelisk or Pavilion desktops?

It requires one standard 288-pin DDR4 DIMM slot; the board has two such sockets and supports a maximum of 32 GB total.
