Introducing the Mainboard
I
In nt tr ro od du uc ct ti io on n
Thank you for choosing KOB P4X266a NDSUX mainboard. The KOB
P4X266a NDSUX mainboard is an ATX mainboard that uses a 4-layer printed
circuit board and measures 305 mm x 190 mm. The mainboard features a
Socket 478 that accommodates Intel Pentium 4 processors supporting system
bus (FSB) speeds of 400 MHz.
The KOB P4X266a NDSUX incorporates the VIA VT8753A Northbridge and
VT8233A (or VT8233) Southbridge chipsets which supports the AC 97 audio
codec, which combines support for DDR (Double Data Rate) SDRAM up to 3
GB.
Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on whether
the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6 GBps or 2.1 GBps by transferring data on both the ris-
ing and falling edges of the clock. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules rather than the 168-pin
DIMMs used by SDRAM.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and sys-
tem bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated
speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 478 processor socket. When choosing a proc-
essor, consider the performance requirements of the system. Performance is
based on the processor design, the clock speed and system bus frequency of
the processor, and the quantity of internal cache memory and external cache
memory.
13

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the Retention Module and CPU:
1. Remove the existing retention module (if applicable).
2. Position the backplate
against the underside of
the mainboard, secure
the 4 screws firmly on
the retention module.
Note: Do not over tighten
the screws.
3. Install your CPU. Pull up
the lever away from the
socket and lift up to 90-
degree angle.
14

4. Locate the CPU cut
edge (the corner with the
pinhole noticeably miss-
ing). Align and insert the
CPU correctly.
5. Press the lever down.
6. Apply thermal grease on top of the CPU.
7. Put the CPU Fan down
on the retention module
and snap the four reten-
tion legs of the cooling
fan into place.
8. Flip the levers over to lock the heat sink in place.
9. Connect the CPU Cool-
ing Fan power cable to
the CPUFAN1 connec-
tor. This completes the
installation.
Note: CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
15

Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Double Data Rate
(DDR) SDRAM memory modules. The memory bus runs at 133 MHz.
The mainboard accommodates three memory modules. You must install at
least one module in any of the three slots. Each module can be installed with
32 MB to 1 GB of memory; total memory capacity is 3 GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1. This mainboard supports unbuffered DDR SDRAM only. Do not attempt to
insert any other type of DDR SDRAM into the slots.
2. Push the latches on each side of the DIMM slot down.
3. Align the memory module with
the slot. The DIMM slots are
keyed with notches and the
DIMMs are keyed with cutouts
so that they can only be in-
stalled correctly.
4. Check that the cutouts on the
DIMM module edge connector
match the notches in the
DIMM slot.
5. Install the DIMM module into
the slot and press it firmly
down until it seats correctly.
The slot latches are levered
upwards and latch on to the
edges of the DIMM.
6. Install any remaining DIMM modules.
