OWC 4GB DDR4 2133 CL15 1.2V 288pin UDIMM memory upgrade

HP Envy Phoenix DDR4 upgrade

This 4GB DDR4 2133MHz UDIMM is built for HP Envy Phoenix desktops including the 860-009nf, 860-010, 860-010ng, 860-011NF and 860-011no. It adds 4GB of non-ECC memory at 1.2V with CL15 timing.

Replacing lower-capacity DDR4 modules

Swapping an existing 4GB stick for this module doubles that slot's capacity, and adding it to a free slot increases total system memory without removing anything. The jump is worth it when the current amount limits multitasking or leaves headroom below the motherboard's supported maximum.

DDR4 2133MHz platform limits

The module runs at the JEDEC-standard 2133MHz data rate; the memory controller will not push it faster without overclocking support that these OEM boards typically lack. Total capacity is capped by the number of 288-pin slots and the chipset's maximum addressable memory, which the system documentation defines.
