* With some processors, memory bus runs at a maximum of 1066 MHz.
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.
