OWC 16GB DDR4 2133MHz CL15 1.2V 288pin UDIMM memory upgrade

HP ENVY Phoenix compatible DDR4

This 16GB DDR4 2133MHz CL15 module is built for HP ENVY Phoenix desktops including the 860-005nf, 860-007na, 860-008na, 860-008nf and 860-009na. It runs at 1.2V as an unbuffered non-ECC UDIMM. The 2Rx8 rank configuration matches the platform requirements. Owners of these specific models can add capacity without compatibility guesswork.

Upgrading from lower capacity DDR4

Systems shipping with 8GB or a single 16GB stick benefit most from this addition. The jump is worth it when multitasking slows down or larger files exceed available memory. It will not help if the board already holds the maximum supported modules or if the bottleneck lies elsewhere. Buyers needing ECC or registered memory cannot use this module.

Tool-free DIMM installation

Installation requires opening the case and pressing the module into a free 288-pin slot until the retention clips click. The usual problem is seating the stick unevenly so the system fails to POST. Another common issue is mixing speeds which forces all modules to run at the slowest rate. No heat spreader means clearance is rarely a concern.
