Memory
Standard
512-MB, 1024-MB or 2048-MB 533-MHz or 667-MHz DDR2 SDRAM; two
SODIMM slots supporting dual channel memory
Maximum
Upgradeable to 4096-MB maximum (2048-MB SODIMM in slots 1 and 2)
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and
speed in both memory slots.
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.
Communications
Integrated Broadcom NetXtreme Gigabit Ethernet PCI Express Controller (10/100/1000 NIC)*
56K V.92 modem** with digital line guard
* 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.
