Memory
Standard
DDR3 PC3-10600 SDRAM (1333 MHz)
*
Two or four SODIMM slots supporting dual-channel memory
2048 MB and 4096 MB SODIMMs
NOTE:
Four memory slots only on models with quad-core processor.
Maximum
Upgradeable to 16384 MB with (4) 4096 MB SODIMMs
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same
size and speed in both memory channels.
* With some processors, memory bus runs at a maximum of 1066 MHz.
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.
Communications
Integrated Intel Gigabit Network Connection (10/100/1000 NIC)
*
56K V.92 modem
**
* 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.
Wireless Devices
Support for a broad range of secure, integrated wireless LAN and wireless WAN options featuring
support for the latest industry standards. Wireless LAN is factory configurable or available as an
option to be added later. Mobile Broadband (WWAN) requires a Windows operating system and is
available in select countries as a standard, factory configurable feature or as an option to be
added later. Integrated Bluetooth is also available (factory configurable only) and can be
combined with any of the supported wireless LAN and wireless WAN options.
