OWC 8GB DDR4 2666 CL19 1.2V UDIMM HP 590 memory upgrade

HP Pavilion 590 Compatible DDR4 Upgrade

This 8 GB DDR4 module is built specifically for HP Pavilion 590-p0007nf, 590-p0008nl, 590-p0013nb, 590-p0016 and 590-p0030 desktops. It targets owners of those systems who need a straightforward capacity increase for everyday multitasking and office workloads. The JEDEC-standard 2666 MHz CL19 specification ensures the module matches the original memory profile exactly.

288-Pin UDIMM Fits Standard Desktop Slots

The unbuffered 288-pin UDIMM installs directly into any free DDR4 DIMM slot on the supported Pavilion 590 motherboards without adapters or configuration changes. Operating at 1.2 V, it draws the same voltage as the factory modules and requires no BIOS tuning. Backward compatibility with 2133 MHz and 2400 MHz buses allows it to down-clock automatically if the platform defaults to a lower speed.

Sustained Operation at JEDEC Voltage

Because the module runs at the standard 1.2 V with no heat spreader, it relies on case airflow for cooling during extended sessions. The non-ECC, single-rank 1Rx8 organisation delivers consistent throughput for long compiles, large spreadsheets or continuous file transfers without the voltage excursions that can trigger throttling on overclocked kits. Compliance with JEDEC and RoHS confirms stable long-term operation within the system's thermal envelope.
