3-1 CPU Installation
Installation
<Figure 1>
Step 1
Open the socket by raising the actuation
lever.
<Figure 2>
Pin 1
Step 2
Align pin 1 on the CPU with pin 1 on
the CPU socket as shown in the
illustration above. The CPU is keyed to
prevent incorrect insertion. Don’t force
the processor into the socket. If it does
not go in easily, check for mis-orienta-
tion and reinsert the CPU.
Make sure the processor is fully
inserted into the socket.

Step 3
Close the socket by lowering and
locking the actuation lever.
Step 4
Apply thermal compound to the top of
the CPU and install the heatsink as
<Figure 4>
shown.
<Figure 5><Figure 6>
Step 5
Install the cooling fan assembly. Press
the two clips in the direction of the
arrows shown in Figure 5 to secure the

assembly to the CPU socket.
NOTES:
•Installing with incorrect CPU fan and heatsink assemblies may damage
the Intel Pentium® CPU. Use Intel’s design thermal solution shown in the
illustrations above: an active heatsink; an extruded aluminum heatsink
base; and a fan attached to the top of the fin array.
•Apply heatsink thermal compound or paste to the CPU to avoid CPU
overheating and damage.
•In accordance with Intel guidelines specifications, do not install a CPU
over 50 times to avoid bending the pins and damaging the CPU.

3-2 Jumper Settings
Installation
JCMOS:
Clear CMOS data Jumper
If the CMOS data becomes corrupted or you
forgot the supervisor or user password,
clear the CMOS data to reconfigure the
system back to the default values stored in
the ROM BIOS.

Settings:
1-2: Normal (Default)
2-3: Clear CMOS
To CMOS Clear data, please follow the steps below.
1. Turn off the system.
2. Change the jumper from “1-2” to “2-3” position
for a few seconds.
3. Replace the jumper on to the “1-2” position.
4. Turn on the system and hold down the <Del>
key to enter BIOS setup.

3-3 System Memory Configuration
The mainboard accommodates two PC2100/PC2700/PC3200 184-pin DIMMs (Dual In-
line Memory Modules):
•Supports up to 2.0GB of 266/333/400MHz DDR SDRAM.
•Supportstwo 64-bit wide DDR data channels.
•Available bandwidth up to 3.2GB/s (DDR400) for single-channel mode and
6.4GB/s (DDR400) in dual-channel mode.
•Registered DIMMs not supported.
•Supports 128-Mb, 256-Mb, 512Mb DDR technologies.
•Supports only x8, x16, DDR devices with four banks.
•SPD (Serial Presence Detect) scheme for DIMM detection support.
•Supports configurations defined in the JEDEC DDR1 DIMM specification only.
This is summarized in <Table 1> below.
MMID1

1#MMIDSD/SSSD/SS
MMID2
)tib-821(
2#MMIDSD/SSSD/SS
* SS: Single-Sided DIMM, DS: Double-Sided DIMM
Note:
• When FSB is 400MHz, DDR266 is supported.
• When FSB is 533MHz, DDR266 and DDR333 are supported.
• When FSB is 800MHz, DDR333 and DDR400 are supported. (With DDR333,
adaptive synchronization aligns to the closest FSB to memory clock ratio,
setting the memory channel to 320MHz).
• We recommend you to use DIMM sockets of the same color to obtain
the best memory performance. It is preferable to use DRAM DIMM
of the same type and size.
• Using non-compliant memory with higher bus speeds (overclocking)
may severely compromise the integrity of the system.
