4 GB DDR3L 1600 SODIMM

This OWC module delivers 4 GB of DDR3L memory at 1600 MT/s with CL11 latency. It runs at 1.35 V in a 204-pin unbuffered SODIMM form factor. The single-rank 1Rx8 design targets compatible HP ProBook notebooks.

Suitable notebooks and limits

The module is validated for HP ProBook 11 G1, 430 G1, 450 G1, 455 G1 and 455 G3 systems. Buyers with other laptop models or desktop platforms should look elsewhere. Systems that require ECC or registered memory cannot use this stick.

The decisive spec

DDR3L 1600 (PC3L 12800) at 1.35 V is the single specification that decides fitment. Match this speed, voltage and pin count exactly or the module will not seat or operate correctly.

Questions about this item

Does the OWC 4GB DDR3L 1600 SODIMM arrive as a single stick, or do I need to buy a second module to reach the full 4 GB capacity?
