Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.
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. With Windows Starter 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.
* Only available when used with 3rd generation processors.
