HP Envy Phoenix Compatible DDR4 Upgrade

This OWC 4GB DDR4 module is built specifically for HP Envy Phoenix desktops including the 860-140, 860-152ng, 860-170VR and 860-180st. It adds 4GB of system memory to support everyday multitasking and application responsiveness. The part number 2U1D41R804GB identifies the exact specification for these models. Buyers needing higher capacities or different form factors should look elsewhere.

JEDEC Standard 288 Pin Unbuffered DIMM

The module follows the DDR4 2133 PC4-17000 standard with CL15 latency and operates at 1.2V. It uses a 288 pin unbuffered non ECC design with a 1Rx8 rank configuration and no heat spreader. This ensures direct compatibility with the motherboard slots in the listed Phoenix systems. Builders working on non HP platforms or requiring registered memory cannot use this module.

Limited Lifetime Warranty and Free Tech Support

OWC backs the memory with a limited lifetime warranty that includes an advanced replacement program and free technical support. The kit is ROHS compliant and tested to meet or exceed OEM specifications for a warranty safe upgrade. Installation is a straightforward DIY process supported by OWC video guides. Users seeking RGB lighting or bundled software utilities will not find them here.

Questions about this item

Does the DDR4 2133 PC4-17000 rating limit bandwidth to 17000 MB/s in the HP Envy Phoenix 860-140?

Yes, the PC4-17000 spec caps theoretical peak transfer at 17000 MB/s; actual throughput depends on the platform's memory controller and channel configuration.

Will the 288-pin UDIMM fit the motherboard slots in the HP Envy Phoenix 860-152ng without a heat spreader?

The module uses the standard 288-pin DDR4 UDIMM form factor with no heat spreader, so it seats directly in the desktop DIMM slots of that model.

What is the correct orientation step when installing this 1Rx8 module in the HP Envy Phoenix 860-170VR?

Align the notch on the gold edge connector with the key in the slot, press down evenly until both side clips snap shut, and verify the module sits flush.
