G Notebook G72 compatible DDR2 SODIMM

This 4 GB DDR2-800 module is built for HP and Compaq G Notebook G72 series laptops including the G72-259WM and G72-227WM. It uses a 200-pin SO-DIMM form factor that matches the factory memory slot in those systems. The stick is unbuffered, non-ECC and runs at the standard 1.8 V for DDR2 notebooks.

Unbuffered 2Rx8 layout with major-brand chips

The module carries a 2Rx8 rank configuration populated with major-brand chipset components and has no heat spreader. Its low-profile design fits the tight clearance inside the G72 chassis without interfering with nearby components. CAS latency is rated CL6 with 6-6-6 timings for stable operation at the rated speed.

4 GB single-stick upgrade for DDR2 platforms

Capacity is limited to 4 GB per module and the platform supports a maximum of 8 GB across two sockets when running a 64-bit operating system. A 32-bit OS will recognise no more than approximately 3.5 GB even with two modules installed. Buyers needing more than 8 GB total memory must choose a different laptop platform.
