1. Attach the CPU and heatsink using silica gel to ensure full contact.
2. It is suggested to select high-quality, certified fans in order to avoid
damage to the motherboard and CPU due to high temperatures.
3. Never turn on the machine if the CPU fan is not properly installed.
4. Ensure that the DC power supply is turned off before inserting or
removing expansion cards or other peripherals, especially when
you insert or remove a memory module. Failure to switch off the DC
power supply may result in serious damage to your system or
memory module.
We cannot guarantee that your system will operate normally while
over-clocked. Normal operation depends on the over-clock capacity of
your device.

ribbon cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray connector to the Ultra DMA 133/100/66 slave device (hard disk drive) and the black
connector to the Ultra DMA 133/100/66 master device. If you install two hard
disks, you must configure the second drive as a slave device by setting its
jumper accordingly. Refer to the hard disk documentation for the jumper
settings.

SPDIF_OUT
This motherboard includes three 32-bit master PCI bus slots and two PCI Express x 16 slots.
PCI Express Slots
PCI Express will offer the following design advantages over the PCI and AGP
interface:
-Compatible with existing PCI drivers and software and Operating Systems.
-High Bandwidth per Pin. Low overhead. Low latency.
-PCI Express supports a raw bit-rate of 2.5 Gb/s on the data pins. This
results in a real bandwidth per pair of 250 MB/s.
-A point to point connection, allows each device to have a dedicated connection without sharing bandwidth.
-Ability to comprehend different data structure.
-Low power consumption and power management features.
PCI Express will take two forms, x16 and x1 PCI Express slots. Whereas the x16
slot is reserved for graphic/video cards, the x1 slots are designed to accommodate less bandwidth-intensive cards, such as a modem or LAN card.
The difference in bandwidth between the x16 and x1 slots are not able to be
sure, with the x16 slot pushing 4GB/sec (8GB/sec concurrent) of bandwidth,
and the x1 PCI Express slot offering 250MB/sec.
If a performance graphics card was installed into x16 PCI
Express slot, 2X12 pin power supply was strongly recommended.

DRAM CAS Latency
When synchronous DRAM is installed, the number of clock cycles of CAS latency
depends on the DRAM timing.

values are: Auto, Manual.
Note: The following options can be activated and configured only when this
option is set as “Manual”.

ACPI function
ACPI stands for “Advanced Configuration and Power Interface”. ACPI is a
standard that defines power and configuration management interfaces between an operating system and the BIOS. In other words, it is a standard that
describes how computer components work together to manage system
hardware. In order to use this function the ACPI specification must be supported by the OS (for example, Windows2000 or WindowsXP). The available
setting values are: Enabled and Disabled.
ACPI Suspend Type
This option is used to set the energy saving mode of the ACPI function.
When you select “S1 (P0S)” mode, the power will not shut off and the
supply status will remain as it is, in S1 mode the computer can be resumed
at any time. When you select “S3 (STR)” mode, the power will be cut off after
a delay period. The status of the computer before it enters STR will be saved
in memory, and the computer can quickly return to previous status when the
STR function wakes. When you select “S1 & S3” mode, the system will
automatically select the delay time.
