OWC 8GB DDR4 2666MHz UDIMM for HP Pavilion

This OWC module adds 8GB of DDR4 memory at 2666MHz to compatible HP Pavilion desktops. It uses a standard 288-pin unbuffered non-ECC design with CL19 latency and 1.2V operation. The part is built for HP Pavilion 590-p0558ng and 595-p0040ns systems.

Check your Pavilion model

Confirm the exact model number matches 590-p0558ng or 595-p0040ns. Verify how many 288-pin DIMM slots are populated and the maximum memory the motherboard accepts. The module runs at 2666MHz but will downclock to 2133MHz or 2400MHz if the platform requires it.

Replaces slower or smaller DDR4 DIMMs in supported

Swapping a 4GB or lower-speed stick for this 8GB CL19 module increases capacity and bandwidth for multitasking. The upgrade is worthwhile when the system currently runs near memory limits during everyday workloads.

Perguntas sobre este artigo

Does the 8GB DDR4 2666MHz UDIMM come alone or with extra parts?

The module ships as a single 8GB stick. No cables, brackets or tools are included. Installation only needs a free 288-pin DDR4 slot on the motherboard.

Should I pick the 2666MHz CL19 version or a faster kit?

This stick runs at 2666MHz CL19 and is backward compatible with 2133MHz and 2400MHz systems. Choose it when your HP Pavilion 590 or 595 specifies 2666MHz memory.

What does the 2666MHz rating deliver inside an HP Pavilion 590?

The 2666MHz speed matches the platform's native memory bus, giving the rated bandwidth without down-clocking. CL19 latency and 1.2V operation keep power draw low.
