	* 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.
