NOTE: This chart does not represent all possible memory configurations. Due to the non-industry standard nature of some third-party
memory modules, we strongly recommend using only HP branded memory modules to ensure compatibility. If you mix memory
speeds, the system will perform at the lower memory speed. Full availability of 4 GB of memory requires Windows Vista Business 64-
bit or Linux. With Windows 32-bit operating systems, the amount of usable memory is dependent upon your configuration, so that
above 3 GB all memory may not be available due to system resource requirements.
*with Mobile Intel GME965 chipset only
Memory Upgrades
512 MB (512 MB x 1)
1024 MB (1024 MB x 1 or 512 MB x 2)

Both memory slots are user accessible. Please refer to the Hardware and Software Guide for installation
procedures. Maximized dual-channel performance requires SODIMMs of the same size and speed in both
memory slots.
