4GB DDR4 2133MHz upgrade for HP ENVY Phoenix

This 4GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It is built specifically for HP ENVY Phoenix 860-001no, 860-001ns, 860-002la, 860-002nc and 860-002nf desktops. The non-ECC unbuffered design matches the original system requirements. Buyers who need ECC error correction or higher capacity sticks cannot use this module.

288-pin UDIMM form factor with no heat spreader

The standard 288-pin UDIMM layout fits directly into the desktop DIMM slots without adapters. Operating at the JEDEC standard 1.2V means no manual voltage adjustment is required in the BIOS. The absence of a heat spreader keeps the module height low for tight chassis clearances. Systems that require registered or load-reduced DIMMs are not compatible with this unbuffered stick.

JEDEC and RoHS compliance with lifetime warranty

Every module is tested to meet or exceed OEM specifications for a warranty-safe upgrade. The package includes the single 4GB DIMM only; no tools, cables or software discs are supplied. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. Users who expect bundled installation software or diagnostic utilities will not find them here.

Questions about this item

What speed does the DDR4 2133 PC4-17000 interface cap at in practice?

The module runs at DDR4 2133 (PC4-17000) with CL15 latency at 1.2 V, so the data rate is limited to 2133 MT/s by the JEDEC DDR4 standard.

What physical slot and clearance does this 288-pin UDIMM need to fit?

It requires a standard 288-pin DDR4 UDIMM slot; the module has no heat spreader, so it fits under low-profile CPU coolers and in tight chassis.

How is the RAM installed and which step do people often miss?

Power off and unplug the HP ENVY Phoenix, open the case, align the notch on the 288-pin DIMM with the slot key, press firmly until both retention clips click, then power on and verify 4 GB appears in BIOS.
