Warning:
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 high temperature.
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 re
moving 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.
Warning:
We cannot guarantee that your system will operate normally while
over-clocked. Normal operation depends on the over-clock capacity
of your device.
Note:
Since BIOS programs are upgraded from time to time, the BIOS
description in this manual is just for reference. We do not guarantee
that the content of this manual will remain consistent with the actual BIOS version at any given time in the future.
Note:
The pictures of objects used in this manual are just for your reference.

Notes:
Take note of the following precautions before you install components or change settings.
1. Use a grounded wrist strap or touch a safely grounded object,
such as an attached power supply, before handling components
to avoid damaging them due to static electricity.
2. Unplug the power cord before opening your chassis or touching
any component.
3. Hold components by their edges to avoid touching any exposed
integrated circuits (ICs).
4. Whenever you uninstall a component, place it on a grounded
anti-static pad or into the anti-static bag that it came in.

socket, otherwise the CPU may be damaged.
Installation of CPU
Follow these steps to install the CPU.
1. Unlock the socket by pressing the lever sideways, then lift it up to a 90
o
angle.
2. Align the cut edge to the gap in the
base of the socket. Carefully insert
the CPU into the socket until it fits in
place.

Installation of CPU Fan
New technology allows processors to run at higher and higher frequencies.
To avoid problems arising from high-speed operation, for example,
overheating, you need to install the proper fan. The following procedure is
provided for reference only, please refer to your CPU fan user guide for the
actual procedure.
1.Locate the CPU retention mechanism
base (surrounds the CPU socket).
3. Attach the fan to the base.
2.If required, apply a light coating of
silica gel to the top of the CPU.
NOTE: The CPU heatsink may have
a pre-applied thermal compound. In
that case, the silica gel is not required.
4.Connect the fan’s power cable
to the appropriate 3-pin terminal
on the motherboard.
12
Warning:
Excessive temperatures will severely damage the CPU and
system. Therefore, make sure that the cooling fan works normally at all times in order to prevent overheating and damage.
875A02 User Manual
Chapter 2 Installation Instructions
Attention:
1.Position the fan with the retention mechanism on top of the
heatsink. Align and snap the four hooks of the retention mechanism to the holes on each corner of the module base.
2.Make sure that the fan and retention mechanism assembly
perfectly fits the headtsink and module base, otherwise you
cannot snap the hooks into the holes.

Memory
This motherboard includes four 184-pin slots with 2.6V Double Data Rate (DDR)
Dual Inline Memory Module (DIMM) sockets, so you can install PC3200/2700/
2100 memory. You must install at least one memory bank to ensure normal
operation.
DIMM1
DIMM2
DIMM3
DIMM4
DDR Memory
The DDR SDRAM technology evolved from the mainstream PC66, PC100, PC133
memory known as Single Data Rate (SDR) SDRAM. DDR memory, however,
has the ability to perform two data operations in one clock cycle, thus providing
twice the throughput of SDR memory.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it has a
184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a DDR DIMM
is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should be
installed only in a socket specially designed for DDR DIMMs.

sockets using the memory configurations in this section.
The following is important information on memory configurations:
1. Installing DDR DIMMs other than the recommended configurations may
cause memory sizing errors or system boot failures. Use any of the
recommended configurations in the following table.

Note:
1. Use only identical DDR DIMM pairs
2. For dual-channel configuration, you may install identical
DIMMS in all four sockets or install identical DIMM pairs
in DIMM1 and DIMM3 (yellow sockets), and identical DIMM
pairs in DIMM2 and DIMM4 (blue sockets).
2. In dual-channel configurations, install only identical (the same type and
size) DDR DIMMs for each channel.
3. Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same
vendor. See the following list of qualified vendors. The following table
