Memory

Standard

DDR3 PC3-8500 SDRAM (1066 MHz)*

 

 

Two SODIMM slots supporting dual-channel memory

 

 

1024 MB, 2048 MB, and 4096 SODIMMs

 

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.

 

* Memory speed is processor dependent.

 

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

Realtek 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.
