Addendum
In order to increase the KM18G series mainboard performance, we have provided a newer BIOS
upgrade with an additional FSB frequency of 200 MHz. For more details, please refer to the
following items.
 When your BIOS version is 1.04 or newer, it will support FSB(Front Side Bus) 100/ 133/ 166/
200MHz. When you set the “System Performance” to the “Optimal ” or the
“Aggressive/Turbo” option in the BIOS Utility, the “FSB Frequency” can be manually
adjust to 100/133/166 or 200MHz. When you set the “System Performance” to “Expert” in
the BIOS Utility, the “FSB Frequency” can be manually adjust to 100～300MHZ.
【BIOS Utility>>Advanced BIOS>>Advanced Chipset Features>>System Performance>>
FSB Frequency……】
 Attention: If you install an FSB 200MHz CPU, in order to avoid booting by FSB166MNz, and
displaying an incorrect CPU type , you must manually adjust the FSB Frequency to 200MHz
in the BIOS Utility.
為了提升 KM18G 系列主機板的擴充性能，本公司提供了新版的 BIOS 程式，使得前置滙流排
頻率規格由原本的 100/ 133/ 166 MHz，進而提升至 200 MHz。詳細情形請參考下列說明。
 若BIOS 版本為 1.04 或以上的版本，則前置匯流排支援至 100/133/166/200MHz。當您在
BIOS 設定中將 “System Performance” 設為“Optimal ”或“Aggressive/Turbo”時，您便可以
將“FSB Frequency”調整至 100/133/166 或200MHz。而當您將“System Performance”設為
“Expert”時，您便可以將“FSB Frequency” 調整至 100～300MHZ。路徑如下：
【BIOS Utility>>Advanced BIOS>>Advanced Chipset Features>>System Performance>>
FSB Frequency……】
 注意: 如果您安裝的 CPU 是200 外頻 CPU，您必須在 BIOS 中手動將前置匯流排（FSB
Frequency）調整至 200MHz。如此一來，才能正確顯示 CPU 型號。否則，將會以前置
匯流排 166MHz 開機而顯示不正確的 CPU 型號。
KM18G シリーズ メインボードの効能を拡張するために、より新しい BIOS を提供して、
FSB(フロント・サイド・バス／Front Side Bus)をもとの 100/133/166MHz から昇格させて、
200MHz までにサポートされるようになりました。より詳細に関しては、次のアイテムをご
参照してください。
 BIOS バージョンが 1.04 である場合、あるいはより新しいのである場合、それは FSB(フ
ロント・サイド・バス／Front Side Bus) 100/133/166/200MHz をサポートします。BIOS
ユーティリィティで「System Performance」は「Optimal」あるいは「Aggressive/Turbo」
オプションに設定される場合に、「FSB Frequency」を手動で 100/133/166 あるいは
200MHz に調整することができます。BIOS ユーティリィティで「System Performance」
は「Expert」に設定される場合に、「FSB Frequency」を手動で 100～300MHZ に調整
することができます。

Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports AMD®processors using a Socket A. Before building your system, we
suggest you visit the AMD website and review the processor installation procedures.
http://www.amd.com
CPU Socket A Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end of
the lever. Match the corner on the CPU with the pin-1 receptor on the socket and lower the CPU onto
the socket. The bottom of the CPU should be flush with the face of the socket.
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps on
the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it onto the
CPUFAN adapter.
Attention: Before starting the system
Please check the installation completely before starting the
system. Verify that the heatsink is properly installed and make
sure the CPU fan is working. Overheating can damage the CPU
and other sensitive com
p
onents.

Enabling Dual-Channel DDR
To enable Dual-Channel DDR functionality, your system must meet certain configuration conditions.
First, you can only use two of the three DIMM slots. You can use DIMM1 and DIMM3 together, or
you can use DIMM2 and DIMM3 together. Second, the DIMM modules that you use must be
identical (capacity, manufacturer and model). See the table below for clarification of DIMM module
options.
Refer to the list below to install the DDR SDRAM memory modules to enable dual-channels facility:
(themeans that a DIMM module is present)
DIMM1 DIMM2 DIMM3
- 
- 
RAM Module Installation:
1. Pull the white plastic tabs on each side of the slot away from the slot.
2. Match the notch on the button of the RAM module with the corresponding pattern in the DIMM
slot. This ensures that the module is inserted properly.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the module
