OWC 4 GB DDR3L SODIMM for HP notebooks

This OWC module delivers 4 GB of DDR3L 1600 memory in a 204-pin SODIMM form factor. It runs at 1.35 V with CL11 latency and a single-rank 1Rx8 layout. The part is validated for the HP 255 G3 and HP 350 G2 systems.

Suitable for HP 255 G3 and 350 G2 owners

The upgrade fits users who need a direct-replacement SODIMM for those specific notebook models. It is not for systems requiring ECC, registered modules, higher voltages, different pin counts, or capacities beyond 4 GB.

204-pin DDR3L 1600 SODIMM specification

The 204-pin DDR3L 1600 interface determines whether the module fits and operates correctly. Match this exact pin count, voltage, and speed to the notebook's memory slot before purchasing.

Questions about this item

How do I confirm the 4GB DDR3L 1600 CL11 module is running at 1.35V after installation?

Enter the BIOS or use a system-information tool such as CPU-Z to verify the memory voltage reads 1.35V and the speed shows 1600 MT/s with CL11 timings.

What comes in the box and do I need any extra parts for the HP 255 G3 or 350 G2?

The package contains one 4GB 204-pin DDR3L SODIMM module; no additional cables, brackets or tools are required for installation in the compatible HP notebooks.

Should I choose the 1Rx8 4GB version or look for a different capacity for my HP 255 G3?

This specific upgrade is a single 4GB 1Rx8 module; if your system has two slots and supports 8GB total, adding a second identical module will give you dual-channel performance.
