Introduction
This manual describes the KTG41/ATXu board made by KONTRON Technology A/S. The board will also be
denoted KTG41.
The KTQ41 boards supports the Intel® Core™2 Quad processor Q9000 series, the Intel® Core™2 Duo
processor E7000 and E8000 series with a maximum TDP of 95W. These processors belong to the Intel
Yorkfield and Wolfdale families.
Use of this Users Guide implies a basic knowledge of PC-AT hard- and software. This manual is focused on
describing the KTG41 special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the short installation procedure stated in the following chapter before
switching-on the power.
All configuration and setup of the CPU board is either done automatically or by the user in the CMOS setup
menus, except for the CMOS Clear jumper (JBAT1), SPI jumper (JP6), Interface BIOS jumper (JP4 and
JP5).

1 Installation procedure
1.1 Installing the board
To get the board running, follow these steps. In some cases the board shipped from KONTRON Technology
has DDR3 DRAM mounted. In this case Step 2 can be skipped.
1. Turn off the power supply
2. Insert the DDR3 DIMM 240pin DRAM module(s)
Be careful to push it in the slot(s) before locking the tabs. For a list of approved DDR3 DIMM modules
contact your Distributor or FAE.
DDR3-800/1066 DIMM 240pin DRAM modules (PC3-6400/PC3-8500) are supported.
3. Install the processor
The CPU is keyed and will only mount in the CPU socket in one way. Use the handle to open/ close the
CPU socket. The Intel® Core™2 Quad, Intel® Core™2 Duo in the LGA775 package are supported, refer
to supported processor overview for details.
Opening the socket:
Apply pressure to the corner with right hand thumb while opening/closing the load lever, otherwise lever can
bounce back like a “mouse trap” and WILL cause bent contacts (when loaded)
1. Disengage Load Lever by depressing down and out on the hook to clear retention tab
2. Rotate Load Lever to fully open position at approximately 135°
3. Rotate Load Plate to fully open position at approximately 100°
Remove Socket Protective Cover
With left hand index finger and thumb to support the load plate edge, engage protective cover finger tab with
right hand thumb and peel the cover from LGA775 Socket while pressing on center of protective cover to
assist in removal.
Set protective cover aside. Always put cover back on if the processor is removed from the socket.
Warning: Do not use Power Supply without 3.3V monitoring watchdog, which is standard
feature in ATX Power Supplies.
Running the board without 3.3V connected will damage the board after a few minutes.
IMPORTANT:
For return goods (RMA): warranty is void if board is returned without Protective cover.
Do NOT touch socket contacts
DDR3 Memory DIMM:
Socket 1
Socket 2

!
Warning: When mounting the board to chassis etc. please notice that the board contains
components on both sides of the PCB which can easily be damaged if board is handled
without reasonable care. A dama
g
ed com
p
onent can result in malfunction or no function at all.
Visually inspect protective cover for damage
If damage observed, replace the cover.
Note: After cover removal, make sure socket load plate and contacts are free of foreign material. Debris may
be removed with compressed air.
Note: Removing protective cover after CPU insertion will compromise the ability to visually inspect socket.
Processor Installation
Locate Connection 1 indicator and the two orientation key notches.
Grasp the processor with thumb and index finger. (Grasp the edges without the orientation notches.) The
socket has cutouts for your fingers to fit into.
Carefully place the package into the socket body using a purely vertical motion. (Tilting the processor into
place or shifting it into place on the socket can damage the sensitive socket contacts.)
CAUTION: Recommend not to use a Vacuum Pen for installation.
Verify that package is within the socket body and properly mated to the orientation keys
Close the socket by:
A. Close the Load Plate
B. While pressing down lightly on Load Plate, engage the Load Lever.
C. Secure Load Lever with Load Plate tab under retention tab of Load Lever
4. Cooler Installation
Use heat paste or adhesive pads between CPU and cooler and connect the Fan electrically to the
FAN_CPU connector.
5. Connecting Interfaces
Insert all external cables for hard disk, keyboard etc. A CRT monitor must be connected in order to
change CMOS settings. When using bootable SATA disk, then connect to SATA0 or SATA2 or select in
BIOS “ATA/IDE Configuration” = Enhanced.
6. Connect Power supply
Connect power supply to the board by the ATX/ BTXPWR and 4-pin ATX connectors. For board to operate
connection of both the ATX/BTX and 4-pin ATX (12V) connectors are required.
7. Turn on the power on the ATX/ BTX power supply
8. Power Button
The PWRBTN_IN must be toggled to start the Power supply; this is done by shorting pins 16
(PWRBTN_IN) and pin 18 (GND) on the FRONTPNL connector (see Connector description). A “normally
open” switch can be connected via the FRONTPNL connector.
9. BIOS Setup
Enter the BIOS setup by pressing the <Del> key during boot up.
Enter Exit Menu and Load Optimal Defaults.
Refer to the “BIOS Configuration / Setup“ section of this manual for details on BIOS setup.
10. Mounting the board to chassis
When fixing the Motherboard on a chassis it is recommended using screws with integrated washer and
having diameter of ~7mm.
Note: Do not use washers with teeth, as they can damage the PCB mounting hole and may cause short
circuits.
Note: To clear all CMOS settings, including Password protection, move the Clr-CMOS jumper (with or
without power) for approximately 1 minute. This will also disable any Secure CMOS setup on the board.
Alternatively, turn off power and remove the battery for 1 minute, but be careful to orientate the battery
correctl
y
when reinserted.

2.4 System Memory support
The KTG41 has two onboard DDR3 DIMM sockets and support the following memory features:
DDR3-800/1066 DIMM 240pin DRAM modules (PC3-6400/PC3-8500)
•1.5V (only) 240-pin DDR3 SDRAM DIMMs with gold-plated contacts
•DDR3-800 (PC3-6400), DDR3-1066 (PC3-8500) SDRAM DIMMs
•DDR3-800/1066 DIMM with SPD timings supported
•Unbuffered, single-sided x8/x16 or double-sided x8/x16 DIMMs
•4 GB maximum total system memory using 64-bit OS. (Shared Video Memory is withdrawn).
•4 GB maximum total system memory using 32-bit OS. ~3GB is displayed in System Properties.
(Shared Video Memory is withdrawn).
•Minimum total system memory: 512 MB
•Non-ECC DIMMs
•Serial Presence Detect
The installed DDR3 SDRAM should support the Serial Presence Detect (SPD) data structure. This allows the
BIOS to read and configure the memory controller for optimal performance. If non-SPD memory is used, the
BIOS will attempt to configure the memory settings, but performance and reliability may be impacted.
Memory Operating Frequencies
Regardless of the DIMM type used, the memory frequency will either be equal to or less than the processor
system bus frequency. For example, if DDR3 800 memory is used with a 800 MHz system bus frequency
processor, the memory clock will operate at 400 MHz. The table below lists the resulting operating memory
frequencies based on the combination of DIMMs and processors.

Note: Kontron offers the following memory modules:
•P/N 1028-6891, DDR3-RAM, 1GB, 240p, 800MHZ, PC3-8500, DIMM
•P/N 1028-6892, DDR3-RAM, 2GB, 240p, 800MHZ, PC3-8500, DIMM
Memory Configurations
1. Asymmetric mode (Single channel). This mode is equivalent to single channel bandwidth operation. This
mode is used when only one DIMM is installed or two DIMMs with different memory capacities are installed.
Technology can vary from one DIMM to the other but if different speed is used, the slowest memory timing
will be used.
2. Interleaved mode (Dual channel). This mode offers the highest throughput. Dual channel mode is enabled
when two DIMM with same memory capacity are installed. Technology can vary from one DIMM to the other
but if different speed is used, the slowest memory timing will be used.

2.5 KTG41 Graphics Subsystem
The KTG41 use the Intel G41 chipset for the graphical control. This chipset contains two separate, mutually
exclusive graphics options. Either the GMA X4500 graphics controller (contained within the AC82G41
GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI Expressx16 add-in card is
installed, the GMA X4500 graphics controller is disabled.
2.5.1 Intel® GMA X4500
Features of the Intel GMA (Graphic Media Accelerator) X4500 graphics controller includes:
•High quality graphics engine supporting
oDX10* and OpenGL* 2.0 compliant
oCore frequency of 400 MHz
o1.6 GP/s pixel rate
oHigh-Quality 3D Setup and Render Engine
oHigh-Quality Texture Engine

•Dynamic Video Memory Technology (DVMT 5.0) support up to 352 MB
2.5.2 DVMT 5.0 support
DVMT enables enhanced graphics and memory performance through highly efficient memory utilization.
DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics
performance. Up to 352 MB of system memory can be allocated to DVMT on systems that have 512 MB or
more of total system memory installed. DVMT returns system memory back to the operating system when
the additional system memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup) for
compatibility with legacy applications. An example of this would be when using VGA graphics under DOS.
Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics
buffer as needed for performing graphics functions.
IMPORTANT: The use of DVMT requires driver support by the operating system.

2.5.3 ADD2 (Advanced Digital Display) card support
The KTQ45 board routes two multiplexed SDVO ports that are each capable of driving up to a 200 MHz pixel
clock to the PCI Express x16 connector. The SDVO ports can be paired for a dual channel configuration to
support up to a 400 MHz pixel clock. When an ADD2 card is detected, the Intel GMA X4500 graphics
controller is enabled and the PCI Express x16 connector is configured for SDVO mode. SDVO mode enables
the SDVO ports to be accessed by the ADD2 card. An ADD2 card can either be configured to support
simultaneous display with the primary VGA display or can be configured to support dual independent display
as an extended desktop configuration with different colour depths and resolutions.
ADD2 cards can be designed to support the following configurations:
•TV-Out (composite video)
•Transition Minimized Differential Signalling (TMDS) for DVI 1.0
•Low Voltage Differential Signalling (LVDS)
•Single device operating in dual channel mode
•VGA output
•HDTV output
•HDMI/UDI support (when used with the HD Audio Link)
Currently Kontron plans the availability of the following ADD2 cards
•P/N 820953, ADD2-LVDS
•P/N 820950, ADD2-Dual LVDS
•P/N 820951, ADD2-Dual Internal DVI
•P/N 820952, ADD2-Dual DVI
