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.
* With some processors, memory bus runs at a maximum of 1066 MHz.
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.
