Support for up to 8192 MB of memory with the installation of optional DDR3 SDRAM memory kits. Both
memory slots are user-accessible. Please refer to the Hardware and Software Guide for installation
procedures. Maximized dual-channel performance requires SODIMMs of the same size and speed in
both memory slots.

* Memory speed is processor dependent.
NOTE:
NOTE:NOTE:
NOTE: This chart does not represent all possible memory configurations. Due to the non-industry
standard nature of some third-party memory modules, we strongly recommend using only HP- branded
memory modules 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.
