16GB DDR4 upgrade for HP ENVY Phoenix 860 series

This 16GB DDR4 2133MHz module is built for HP ENVY Phoenix 860-140, 860-152ng, 860-170VR and 860-180st desktops. It adds capacity to systems that still have a free 288-pin UDIMM slot. The non-ECC, unbuffered design matches the original memory specification for these models.

Check your motherboard slots

Verify that your HP ENVY Phoenix has an available 288-pin DDR4 DIMM slot before ordering. The module runs at 2133MHz with CL15 latency and 1.2V voltage, so existing memory should match these timings for stable dual-channel operation. Confirm the system supports non-ECC unbuffered UDIMMs.

JEDEC compliance and lifetime warranty support

The module meets JEDEC standard specifications and is ROHS compliant, ensuring a warranty-safe upgrade for your HP desktop. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. No heat spreader is included, so airflow around the module is unchanged.

Questions about this item

Does the OWC 2U1D42R816GB come as a single 16GB stick or do I need to buy a pair?

This listing is for one 16GB DDR4 2133MHz CL15 module. Add a second stick if your HP Envy Phoenix board has two free slots and you want dual-channel bandwidth.

Should I choose this 2133MHz CL15 module or a faster DDR4 kit for my HP Envy Phoenix 860-140?

The 860-140, 860-152ng, 860-170VR and 860-180st all specify DDR4 2133MHz. A faster kit will simply down-clock to 2133MHz, so this CL15 1.2V module matches the platform without extra cost.

What does the PC4-17000 rating mean once the module is installed in my desktop?

PC4-17000 equals 2133 MT/s peak transfer rate. In the Envy Phoenix it delivers 16GB of non-ECC unbuffered memory at CL15 latency, raising total system capacity for multitasking and larger workloads.
