* Memory speed is processor dependent.
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. Availability of 4 GB or more of memory requires Windows Vista Business
64-bit or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available due to system resource
requirements.

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.
