8GB DDR4 2666MHz UDIMM for HP Pavilion 590

This OWC 8GB DDR4 2666MHz CL19 1.2V 288-pin Non-ECC UDIMM is built for HP Pavilion 590-p0000nc, 590-p0000ns, 590-p0002nb, 590-p0003nl and 590-p0004nl desktops. It meets JEDEC PC4-21300 specifications for a warranty-safe memory upgrade. The module is unbuffered and single-rank 1Rx8 without a heat spreader.

Who this suits and who should look elsewhere

Buyers wanting a direct-fit 8GB DDR4 module for the listed HP Pavilion 590 systems will find this part validated for those models. Systems requiring ECC registered memory or a different DDR generation cannot use this UDIMM. Builders needing capacities beyond 8GB per slot or speeds above 2666MHz must select a different specification.

The deciding specification: DDR4 2666 CL19 1.2V

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V in a 288-pin unbuffered DIMM form factor. It is backward compatible with 2133MHz and 2400MHz bus speeds. This speed, voltage and pin layout determine whether the memory will be accepted by the target HP Pavilion 590 motherboard.
