OWC 8GB DDR4 2133 CL15 1.2V UDIMM memory upgrade for HP Envy Phoenix 860

OWC 8GB DDR4 2133 UDIMM for HP Envy Phoenix 860

This OWC memory module adds 8GB of DDR4 2133 capacity to compatible HP Envy Phoenix 860 desktops. It is a 288-pin unbuffered UDIMM rated at CL15 latency and 1.2V operation. The part is designed as a direct, warranty-safe upgrade for the listed workstation models.

Check motherboard slots and maximum supported memory

Verify that your HP Envy Phoenix 860 has a free 288-pin DDR4 DIMM slot before ordering. Confirm the system’s maximum total memory limit in the HP documentation so the new module does not exceed it. The board must accept non-ECC unbuffered DDR4 at 2133 MT/s.

Replaces slower or smaller DDR4 modules

Swapping an existing 4GB or lower DDR4 stick for this 8GB module increases total capacity for multitasking and larger workloads. The upgrade is worthwhile when the current configuration leaves empty slots or runs at a lower speed than 2133 MT/s. Systems already at the memory ceiling or using a different DDR generation cannot use this part.
