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.
