Memory
Standard
800 MHz DDR2 SDRAM, or 1066/1333 MHz DDR3 SDRAM
*
;
two slots supporting dual channel memory
1024 MB, 2048 MB, 3072 MB, or 4096 MB
Maximum
Upgradeable to 8192 MB with 4096 MB SODIMMs in slots 1 and 2
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and
speed in both memory slots.
* Maximum memory speed will vary based on system configuration.
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 Windows Vista Business 64-bit 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
Marvell Ethernet (10/100/1000 NIC)
*
Optional 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 factory configurable feature only. Integrated Bluetooth is also available (factory
configurable only) and can be combined with any of the supported wireless LAN and wireless WAN options.
