OWC 2S1D41R804GB 4GB DDR4 2133 CL15 1.2V 260-pin SODIMM

HP 17-inch laptop memory upgrade

This 4 GB DDR4 SODIMM is built for the HP 17-x007nf, 17-x007ng, 17-x007no, 17-x008nf and 17-x008ng notebooks. It uses a 260-pin unbuffered, non-ECC layout at 1.2 V. The module adds capacity to systems that shipped with a single slot populated or that need a direct replacement for a failed stick.

Sustained load behaviour at DDR4 2133 CL15

At the rated PC4-17000 speed and CL15 latency the module delivers steady throughput during long compile jobs, virtual-machine sessions or large spreadsheet recalculations. JEDEC compliance means the SPD timings are followed without manual tuning, so the memory controller never drops to a lower gear halfway through a workload.

Physical build and daily implications

The stick has no heat spreader, keeping the profile low enough for tight laptop chassis. Gold-edge contacts on the 260-pin connector resist oxidation through repeated seatings. Buyers who want more storage, a second module for dual-channel bandwidth or ECC error correction will need a different part.
