note:
In accordance with Microsoft support policy, HP does not support the Windows 8 or Windows 7 operating system on products configured with Intel and AMD 7th generation or later processors, or provide any Windows 8 or Windows 7 drivers.

Multicore is designed to improve performance of certain software products. Not all customers or software applications necessarily benefit from use of this technology. 64-bit computing system required. Performance and clock frequency vary depending on application workload and hardware and software configurations. Intel numbering is not a measurement of higher performance.

note:
Addressing memory above 4 GB requires a 64-bit operating system. With Windows 32-bit operating systems, the amount of usable memory is dependent upon the configuration, therefore above 3 GB, all memory might not be available due to system resource requirements.

Memory modules support data transfer rates up to 2400 MT/s; actual data rate is determined by the system configured processor. See processor specifications for supported memory data rate.
