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 the system’s components.
CPU Processor Installation
This mainboard supports Intel®Pentium®Extreme Edition/ Pentium®4 Extreme Edition/ Pentium®D/
Pentium®4/ Celeron®D Processor using a Socket 775. Before building your system, we suggest you to
visit the Intel website and review the processor installation procedures. http://www.intel.com
CPU Socket 775 Configuration Steps:
Locate the CPU socket 775 on your mainboard
and nudge the lever away from the socket as
shown. Then lift the lever to a 140-degree
angle (A). Next, lift up the iron cover (B).
There are 2 distinctive marks located near the
corners of the socket on the same side as the
lever as shown (C). Match these marks with
the marks on the CPU and carefully lower the
CPU down onto the socket (D).
Replace the iron cover and then lower the
lever until it snaps back into position (E). This
will lock down the CPU (F).
Smear thermal grease on the top of the CPU. Lower the CPU fan onto
the CPU/CPU socket and secure it using the attachments or screws
provided on the fan. Finally, attach the fan power cord to the
CPUFAN header.

Attention
DO NOT touch the CPU pins in case they are damaged. Also, make sure that you have
completed all installation steps before powered on the system. Finally,
double-check that the cooling fan is properly installed and the CPU fan power cord
is securely attached, in case your CPU and other sensitive components are damaged
because of high temperatures.

FAN Headers: CPUFAN, AUXFAN, CHASFAN, FAN4
There are four fan headers available for cooling fans. The cooling fans play an important role in
maintaining ambient temperatures in your system. The CPUFAN header is attached with a CPU cooling
fan. The CHASFAN, AUXFAN, and FAN4 headers are attached with other cooling fans.

Memory Installation: DIMM1/2/3/4
The VP-MB945G provides two DIMM (Dual In-Line Memory Modules) sockets which allowing you to install
240-pin, unbuffered non-ECC, DDRII 667/ 533/ 400 SDRAMs. It also supports Dual Channel Technology
and allows you installing a total memory capacity of 2 GB.
Attention
You can avoid damaging your CPU due to high temperatures with proper cooling
equipment. It is recommended that attach a cooling fan on top of your CPU. Use
the CPUFAN header to attach the fan cord.
On most fan power cord, the black wire of the fan cable is the “ground” and
should be attached to pin-1 of the header.
Attention
It is recommended that to install memories which are identical specifications
(same timing specifications and same DDR II speed) to achieve the best
effects. It may cause the failure of power-on or lower memory speed if
installing different type, SPD (series presence detects) memories.

Mainboard VP-MB945G

How to enable Dual-Channel DDRII:
1. This mainboard provides Dual-Channel functionality for the two DIMM sockets. Enabling
Dual-Channel can significantly increase your data access rates. DIMM1 and DIMM2 share one
channel.
2. For enabling Dual-Channel, you have to install two memories in the DIMM sockets at the same time;
according to the definition by Intel, once one channel of the memory capacity is the same with the
other channel, then Dual-Channel will be enabled.
3. For example, if you install one 256 MB memory in DIMM1 and the other one in DIMM2 (256MB x 2 =
512MB), so that the Dual-Channel can be enabled.
4. If you only need to install one memory, then the Dual-Channel won’t be enabled.
Memory Installation Steps:
1. Pull the white plastic tabs at both ends of the slot away from the slot.
2. Match the notch on the RAM module with the corresponding pattern in the DIMM slot. This will ensure
that the module will be inserted with the proper orientation.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the module snaps
into place.
4. Repeat steps 1, 2 & 3 for the remaining RAM modules.

installation may vary slightly from the pictures.
