OWC 8GB DDR4 2666MHz UDIMM

This OWC module adds 8GB of DDR4 memory at 2666MHz to compatible HP Pavilion 590 desktops. It uses a standard 288-pin UDIMM form factor with CL19 latency and 1.2V operation. The non-ECC, unbuffered design suits mainstream consumer platforms. Buyers seeking a straightforward capacity increase for the listed models can install this kit.

Check your HP Pavilion model number

Verify that your system matches one of the supported variants: 590-p0039, 590-p0054, 590-p0055na, 590-p0067cb or 590-p0090na. Confirm the motherboard has a free 288-pin DDR4 slot and accepts non-ECC unbuffered modules. The memory runs at 1.2V and is backward compatible with 2133MHz and 2400MHz bus speeds. Ensure the BIOS is current for best results.

Fits a single DIMM slot for easy expansion

Insert the stick into an empty DDR4 slot; no heat spreader means it clears most standard CPU coolers. The JEDEC-compliant PCB works with the existing memory controller without voltage changes. Adding this module frees up system resources for multitasking and larger workloads. It leaves other slots open for future upgrades if the board supports more capacity.

商品問答

What comes in the box and do I need any extra parts to install this 8GB DDR4 2666MHz module?

The box contains the single 288-pin UDIMM. No extra parts are required; it installs directly into an empty DIMM slot on your HP Pavilion 590 motherboard.

Which capacity or speed version should I choose for my HP Pavilion 590-p0054?

This module is the 8GB DDR4 2666MHz CL19 1.2V version validated for your model. It also runs at 2133MHz or 2400MHz if the system requires a lower speed.

What does the PC4-21300 2666MHz rating mean once the RAM is running in my Pavilion 590?

It delivers 2666 MT/s bandwidth at CL19 latency and 1.2V, giving your desktop the JEDEC-standard throughput the motherboard expects for smooth multitasking.
