2.1.3 Performance
• DDR DRAM Optimized Performance: This motherboard supports a new
generation memory, Double Data Rate (DDR) Dynamic Random Access Memory
(DDR DRAM). 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 133MHz DDR SDRAM and 1.6GB/s for 100MHz DDR SDRAM.
• Onboard Audio: (Optional) Audio models come with the six-channel C-Media
CMI8738 PCI audio controller that supplies HRTF 3D positional audio functions.
The chip supports software access to PC DVD 5.1/6.1 and AC-3/DTS via SPDIF.
Other integrative featues include: full DVD playback, PCtel 56K modem, and
even Karaoke echo effects. The chip offers 24-bit SPDIF digital recording and
playback with additional support for legacy audio SBPRO™ and FM emulator/
DLS wavetable music synthesis. A software 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.
• PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards are PC’99 compliant. The new PC’99 requirements for systems
and components are based on the following high-level goals: Support for Plug-
n-Play compatibility and power management for configuring and managing all
system components, and 32-bit device drivers and installation procedures for
Windows95/98/NT . Color-coded connectors and descriptive icons make
identification easy as required by PC’99.
• High-Speed Data Transfer Interface: Support for UltraDMA/133 through the
onboard IDE bus master controller quadruples the UltraDMA/33 burst transfer
rate. UltraDMA/133 is backward compatible with DMA100/66/33, and other
existing DMA devices to save the need to upgrade current EIDE/IDE drives.
(UltraDMA133/100/66 requires a 40-pin 80-conductor cable).
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master
busses to the memory and processor.
