Compatible HP Pavilion 590 models

This 16GB DDR4 UDIMM is built for HP Pavilion 590 desktops including the 590-p0099nb, 590-p0099nl, 590-p0305ns, 590-p0556ng and 590-p0557ng. It installs in a standard 288-pin slot and runs at 1.2V without ECC or buffering.

Who should buy and who should not

Owners of the listed Pavilion 590 systems who want a straightforward memory upgrade will find this module fits and works. Builders using a different motherboard, a laptop, or a workstation that requires registered or ECC memory should look at other parts.

The spec that decides fit

The module is a 288-pin DDR4 UDIMM rated at 2666MHz with CL19 latency and 1.2V operation; if your board needs a different pin count, voltage, speed grade or error-correction type this stick will not work.

Questions sur cet article

Will this 2666MHz DDR4 module run with my existing 2133MHz or 2400MHz sticks in the Pavilion 590?

Yes, the module is backward compatible with 2133MHz and 2400MHz speeds, so it will downclock to match your current memory.

How can I verify the 16GB CL19 UDIMM is recognised at the correct 2666MHz speed after installation?

Open Task Manager’s Performance tab or run CPU-Z; both will show 16GB running at 2666MHz with CL19 timings if the module is seated properly.

Does the 288-pin 1.2V UDIMM ship alone, or are tools or extra brackets included for the HP Pavilion 590?

Only the single 16GB DDR4 UDIMM is supplied; no screwdriver, anti-static strap or mounting hardware is included.
