HP Pavilion 590 DDR4 Upgrade

This 4 GB DDR4 2666 MHz UDIMM is built for the HP Pavilion 590-p0007nf, 590-p0008nl, 590-p0013nb, 590-p0016 and 590-p0030. It installs in a standard 288-pin desktop slot and runs at 1.2 V without ECC or buffering.

Who this suits and who it does not

It suits owners of those five Pavilion 590 models who want a single 4 GB module to add capacity or replace a failed stick. Builders needing ECC, registered DIMMs, higher density than 4 GB, or a different form factor such as SODIMM should look elsewhere.

Deciding specification

The module is a 1Rx8 non-ECC unbuffered UDIMM rated PC4-21300 CL19 at 1.2 V; if your Pavilion 590 requires that exact rank and timing the part will work, otherwise it will not.
