Asus P5ND2 SE - Manual (Page 16)

1-4 Chapter 1: Product introduction
CPU Lock Free
This feature allows you to adjust the CPU multiplier to 14x. Setting the
appropriate BIOS setting automatically reduces the CPU multiplier value for
more flexibility when increasing external FSB.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0
specification, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is
backward compatible with USB 1.1. See pages 1-25 and 1-30 for details.
Serial ATA 3Gb/s technology
The motherboard supports the Serial ATA 3 Gb/s technology through
the Serial ATA interfaces. The Serial ATA 3 Gb/s specification provides
twice the bandwidth of the current Serial ATA products with a host of
new features, including Native Command Queueing (NCQ), and Power
Management (PM) Implementation Algorithm. Serial ATA allows for thinner,
more flexible cables with lower pin count, reduced voltage requirement. See
page 1-29 for details.
