- Supports from 8MB to 64MB 3.3V unbuffered
SDRAM DIMM or 3.3V unbuffered EDO DIMM for
DIMM slot.
- Provides 256KB/512KB L2 Pipelined Burst Cache on
board.
- Provides 2 kinds of cache chips for users:
256KB/512KB cache on board.
- Supports 2 PCI Bus Master (Bus Master works as
DMA Mode 2 type) IDE ports.
- Supports PIO mode up to Mode 4 Timings.
- Supports "Ultra DMA/33" synchronous DMA mode
transfers up to 33MBytes/sec.
- Supports 2 Fast IDE interfaces for up to 4 IDE devices
e.g. IDE hard disks and CD ROM drives.
- Supports 3 green modes: Doze, Standby and Suspend.
- ACPI (Advanced Configuration and Power Interface) is
also implemented on P5I430TX Titanium IB+. ACPI
providing more Energy Saving Features for the future
operation system (OS) supporting OS Direct Power
Management (OSPM) functionality. With these
features implemented in the OS, PCs can be ready
around the same time everyday, yet satisfy all the
energy saving standards. To fully utilize the benefits of
ACPI, an ACPI-supported OS such as in the next
release of Windows 9X must be used.
- When CPU fan malfunctions, the system will deactivate the
CPU Clock line to decrease CPU utilization in order to speed
up detection system overheating. This will prevent CPU
damage caused by system overheating. The CPU utilization
will resume normal operations when temperature falls below a
safe level (Optional).
- The CPU fan will power 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.
- The system can be in one of two states, one is Sleep
mode and the other is the Soft-Off mode. Pushing the
power button for less than 4 seconds places the system
into Sleep mode. When the power button is pressed for
more than 4 seconds, it enters the Soft-Off mode.
- This allows a computer to be turned on remotely
