1024 MB and 2048 MB SODIMMs
Standard memory up to 4096 MB
Maximum
Upgradeable to 8192 MB with optional 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 Windows Vista Business 64-bit 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.
