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. 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.

* The term "10/100/1000" or "Gigabit" Ethernet indicates compliance with IEEE standard 802.3ab for
Gigabit Ethernet, and does not connote actual operating speed of 1 Gb/s. For high-speed transmission,
connection to a Gigabit Ethernet server and network infrastructure is required.
** Designed for downloads from 56K modem compliant sources. Maximum achievable download
transmission rates currently do not reach 56 KB/s, and will vary with line conditions. Modem availability
is subject to country regulatory approval.
