HP x360 310 G1 memory upgrade

This 4 GB DDR3L SODIMM is built specifically for the HP x360 310 G1 notebook. It runs at 1600 MHz with CL11 timing and operates at 1.35 V. The single-rank 1Rx8 module uses 204-pin unbuffered non-ECC layout. OWC tests every stick to meet JEDEC and RoHS standards.

Owners of the HP x360 310 G1 needing more RAM

Buyers with a different laptop model cannot use this module because the pin-out and voltage are tailored to the 310 G1. Systems that require ECC or registered memory are not supported. Anyone wanting a higher capacity than 4 GB must look for a different kit.

Simple SODIMM installation

The module slides into the notebook's memory slot without tools in most cases. OWC provides a basic installation video for guidance. The most common issue is inserting the stick at the wrong angle so it does not seat fully, which prevents the system from booting.

Questions about this item

What laptop model must I own for this 204-pin DDR3L 1600 SODIMM to fit and be recognised?

It is validated for the HP x360 310 G1; the module matches that system's DDR3L 1.35 V SODIMM slot and CL11 timing.

Can I keep my existing memory and add this 4 GB module alongside it?

OWC recommends matching capacity, speed and manufacturer for optimal performance, so mixing with different modules may not deliver the best results.

How do I confirm the module is running at the rated 1600 MT/s after installation?

Check the memory speed reported in the BIOS or a system-information tool; it should show DDR3L 1600 (PC3L-12800) at CL11.
