OWC 4GB DDR4 2133MHz PC4-17000 CL15 1.2V 260pin SODIMM memory upgrade

System-specific DDR4 SODIMM for HP Envy all-in-ones

This 4 GB DDR4 module is built for HP Envy 27-b014, 27-b015qe, 27-b021, 27-b100la and 27-b100nb systems. It uses the standard 260-pin SODIMM form factor and runs at 1.2 V without ECC or buffering. Owners of those models can add capacity with a single stick that matches the factory specification.

Speed and timing locked to DDR4 2133 CL15

The module operates at DDR4 2133 (PC4 17000) with a CAS latency of 15. That exact speed and timing pair is the deciding factor; a faster or slower module will not keep the memory controller in its validated range. Buyers who need a different data rate or latency should look elsewhere.

Steady operation at JEDEC voltage

Rated at 1.2 V and compliant with JEDEC specifications, the stick maintains its 2133 MHz clock and CL15 timing under continuous load without raising voltage. The unbuffered, single-rank design avoids extra signal loading, so thermal behaviour stays predictable during long work sessions. Builders who want overclocking headroom or XMP profiles are not served by this part.
