2.1.3 Performance and Intelligence
• DDR SDRAM Optimized Performance: This motherboard supports Double Data
Rate (DDR) Dynamic Random Access Memory (DDR SDRAM). This new
memory technology increases performance by executing two actions per clock
cycle, resulting in data transfer rates of up to 2.1 GB/s for 266MHz DDR SDRAM
and 1.6 GB/s for 200MHz DDR SDRAM.
• Onboard Audio: Audio models come with the six-channel C-Media CMI8738
PCI audio controller that supplies HRTF 3D positional audio functions. A soft-
ware package helps setup the multi-channel PC sound system.
• ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more
Energy Saving Features for operating systems that support OS Direct Power
Management (OSPM) functionality. With these features employed in the OS,
PCs can be ready around the clock but comply with energy saving standards. To
fully utilize the ACPI benefits, use an ACPI-supported OS such as Windows 98.
• Onboard LED: A green LED lights up to indicate that power is available on-
board. It reminds users that standby power is available. The LED also serves as
a reminder to disconnect the power supply when making any change to the
configuration.
• PCI USB2 Card: A 4-port USB PCI card is bundled with the A7M266-D.
• Concurrent PCI: Multiple PCI transfers are now harmonized from the PCI
master bus to the memory and processor.
• Remote Ring-On (requires modem): This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on-hand, users
can access vital information from their computers anywhere.
• SMBus: Features the System Management Bus interface used to physically
transport commands and information between SMBus devices.
• Desktop Management Interface (DMI): Supports DMI through BIOS that al-
lows hardware to communicate within a standard protocol and create a higher
level of compatibility. (Requires DMI-enabled components.)
• ASUS C.O.P. (CPU Overheating Protection): With AMD
®
Athlon XP
™
/ Athlon MP
™
installed, the motherboard offers users ASUS C.O.P. automatic
CPU Overheating Protection to prolong the life of the entire system. If the CPU
temperature becomes excessive, the PC shuts down automatically.
• Auto Fan Off: The system fans powers off automatically even in sleep mode.
This function reduces both energy consumption and system noise, and is an
important feature in implementing silent PC systems. Note: the user must change
the default setting in BIOS to take advantage of this feature.
