	NOTE: Due to the non-industry standard nature of some third-party memory modules, we recommend
	HP branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the
	lower memory speed. Above 3-GB, all memory may not be available due to system resource
	requirements.

	Gigabit Ethernet, and does not connote actual operating speed of 1 Gb/sec. For high speed
	transmission, connection to a Gigabit Ethernet server and network infrastructure is required.
