Support for up to 4096 MB* of memory is available (with the installation of optional DDR2 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.
NOTE: This chart does not represent all possible memory configurations. Due to the non-industry NOTE: NOTE: NOTE:
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.
