* 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.
