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 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.
