HP Envy Phoenix 860 DDR4 upgrade

This 16 GB DDR4 2133 MHz CL15 UDIMM is built for HP Envy Phoenix 860 desktops including the 860-080nz, 860-081no, 860-082no, 860-084no and 860-090nz. It runs at 1.2 V and meets JEDEC PC4-17000 specifications for a warranty-safe memory increase.

Who this suits and who should look elsewhere

The module fits owners of the listed Phoenix 860 models who want a simple capacity boost for multitasking and larger workloads. It will not work in laptops, small-form-factor PCs or any system that requires SODIMM, ECC, registered or higher-speed DDR4 memory.

Installation and common pitfalls

The 288-pin unbuffered DIMM installs in the standard desktop memory slot with a straight press until the retention clips click. Common issues include mixing with existing modules that have different speeds or latencies, which can force the system to run at the lowest common settings or fail to boot.

Questions about this item

Does this 288-pin DDR4 2133MHz module need an HP Envy Phoenix 860 series desktop to work?

Yes, the module is validated for HP Envy Phoenix 860-080nz, 860-081no, 860-082no, 860-084no and 860-090nz systems that accept 288-pin DDR4 UDIMMs.

Can I keep my existing DDR4 2133MHz CL15 sticks and add this 16GB 2Rx8 module alongside them?

The module runs at 1.2V with CL15 timing; mixing ranks is usually fine but the system will run all modules at the slowest common speed and latency.

How do I confirm the new 16GB stick is running at PC4-17000 2133MHz after installation?

Open Task Manager or BIOS and verify the reported speed shows 2133 MHz and the total installed memory has increased by 16 GB.
