Compatible EliteBook Upgrade

This OWC module adds 4 GB of DDR3L 1600 memory to HP EliteBook 745 G2, 745 G3, 750 G1, 750 G2 and 755 G2 notebooks. It uses a single 204-pin SODIMM running at 1.35 V with CL11 latency and 1Rx8 organisation. The part meets JEDEC and RoHS standards for a warranty-safe upgrade.

Not for other platforms

Buyers who need memory for a different laptop family or a desktop board cannot use this module. It is also unsuitable for systems that require ECC, registered DIMMs, a different voltage or a higher capacity per slot.

Straightforward SODIMM swap

Installation typically involves removing the bottom cover, releasing the retention clips and pressing the stick in until it clicks. The most common issue is seating the module unevenly, which prevents the notebook from posting. Matching capacity, speed and brand across all slots avoids timing mismatches.
