64-Bit Computing
64-bit processors are designed to take advantage of 32 and 64 bit
computing.
64-bit computing requires that the following hardware and software
requirements are met:
64-bit Operating System
64-bit CPU, Chipset and BIOS (Basic Input/Output System)
64-bit Device drivers
64-bit applications
Certain device drivers and/or applications may not be compatible with a
64-bit CPU and therefore may not function properly. A 32-bit version of the
operating system is preinstalled on your computer unless explicitly stated
that the operating system is 64-bit.
Memory (Main System)
Part of the main system memory may be used by the graphics system for
graphics performance and therefore reduce the amount of main system
memory available for other computing activities. The amount of main
system memory allocated to support graphics may vary depending on the
graphics system, applications utilized, system memory size and other
factors. Computers configured with a 32-bit operating system can address
up to 3GB of system memory. Only computers configured with a 64-bit
operating system can address 4GB or more of system memory.
