* With some processors, memory bus runs at a maximum of 1066 MHz.
** Requires quad-core processor configuration with four memory slots.
NOTE: NOTE: NOTE: This chart does not represent all possible memory configurations. Due to the non-industry NOTE:
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.
