* Memory speed is processor dependent.
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 or more of memory requires a
Windows 64-bit operating system 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.
