CPU performance may also vary from specifications due to design
configuration.
Under some conditions, your computer product may automatically shut-
down. This is a normal protective feature designed to reduce the risk of lost
data or damage to the product when used outside recommended
conditions. To avoid risk of lost data, always make back-up copies of data
by periodically storing it on an external storage medium. For optimum
performance, use your computer product only under recommended
conditions. Read additional restrictions in your product documentation.

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.
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
approximately 3 GB of system memory.
Computers configured with a 64-bit operating system can address 4 GB or
more of system memory.
Hard Disk Drive (HDD) Capacity
One Gigabyte (GB) means 10
9
= 1,000,000,000 bytes using powers of 10.
The computer operating system, however, reports storage capacity using
powers of 2 for the definition of 1 GB = 2
30
= 1,073,741,824 bytes, and
therefore shows less storage capacity. Available storage capacity will also
be less if the product includes one or more pre-installed operating systems,
such as Microsoft Operating System and/or pre-installed software
applications, or media content. Actual formatted capacity may vary.
