1-1. Features of NV7m Motherboard

This motherboard is designed for AMD Socket A Athlon™ XP, Athlon™ and Duron™ processors. It
supports the AMD Socket-A structure, with up to 1 GB (Unbuffered & Non-ECC) of memory, super I/O.
and Green PC functions. The ABIT NV7m is an excellent computer motherboard based on the innovative
nForce 420D chipset, which supports powerful Geforce 2 3D graphics, AC3 audio and LAN for an all in
one Micro ATX form factor solution with high performance value.

The NVIDIA nForce 420D chipset used in this motherboard supports two DDR DIMMs up to 1 GB
maximun. The memory controller can support Non-ECC DDR (up to DDR PC 2100 it running on 133
MHz) memory and support twin bank memory architecture for up to 4.2GB/s bandwidth. The AGP
interface can support external AGP slot with AGP 1X/2X/4X (1.5V graphics card only) capability and
Fast Write Transactions.

The NV7m has a built in Ultra DMA 100 function. This means that it provides speedier HDD throughput
boosting overall system performance. Ultra DMA 100 is the new standard for IDE devices. It enhances
existing Ultra DMA 33 technology by increasing both performance and data integrity. This new
high-speed interface almost doubles the Ultra DMA 66 burst data transfer rate to 100 Mbytes/sec. The
result is maximum disc performance using the current PCI local bus environment. Another benefit is you
can connect four IDE devices in your system through either Ultra DMA 66 or Ultra DMA 100. You will
have more flexibility to expand your computer system.

This motherboard also supports three PCI slots and one AGP slot. This motherboard has built-in hardware
monitoring functions that monitors and protects your computer, insuring a safe computing environment. It
equips the Realtek ALC201A 2-channel audio and 8201L 10/100 Mbps LAN controller.

2-1. Installation of the AMD Athlon™ XP, Athlon™ and Duron™

CPU

Note

! Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor. Failing

to install these items may result in overheating and processor damage.

! The AMD Socket A processor will produce a lot of heat while operating, so you need to use a large

heat sink that is especially designed for the AMD socket A processor. Otherwise, it may result in
overheating and processor damage.

! If your processor fan and its power cable are not installed properly, never plug the ATX power

cable into the motherboard. This can prevent possible processor damage.

! Please refer to your processor installation manual or other documentation with your processor for

detailed installation instructions.

The AMD Socket A Athlon™ XP, Athlon™ and Duron™ processor installation is easy, like Socket 7

®

easily fix the processor firmly into position. Figure 2-1 shows you what the socket A looks like, and how
to open the lever. The socket A has more pins than the socket 7. Therefore, a Pentium level processor
cannot be inserted into a socket A.

processors before. Because it uses the “Socket A” ZIF (Zero Insertion Force) socket, you can

When you raise the lever, you have to loosen the socket lock. Please raise the lever to the end, and
prepare to insert the processor. Next, you need to align the processor pin 1 to the socket pin 1. If you put
it in the wrong direction, you will not be able to insert the processor easily, and processor pins will not
fully go into the socket. If this is the case, please change the direction, until it easily and fully inserts into
the socket A. See Figure 2-2 at the same time check the processor temperature detection thermistor height
(if your motherboard has this component), then you can slowly insert the processor into the Scoket A.
Finally, you need to check that the processor edge and the Socket A edge is parallel. It should be parallel
and not tilted.

When you finish the above, push the lever down to its original position, you should feel the lever lock the
socket A. You have then finished the processor installation.

NV7m Motherboard

Installing the Motherboard

Heatsink Installation Hints

Because the processor will produce a lot of heat while operating, we suggest you use a heatsink approved
by AMD to be safe and to keep the processor temperature within normal operation temperatures. The
heatsink will be large and heavy, so the fixing plate has a strong tension. When you install the heatsink on
to the processor and its socket, you have to very carefully fix the fixing plate to the processor socket hook
on both sides. If you do not pay attention to this, you may make the fixing plate scratch the PCB surface
and cause circuit damage, break socket hooks or damage the die on the top of processor.

Please follow the sequence metioned below, Do Not
inverse the sequence. Otherwise, you may have a
situation like the photo on the left. Because of the
design of the CPU socket, the left side hooks are not
as strong as the right side hooks. If you follow our
suggestions you will prevent your processor and
socket from damage.

Note

Considering the chassis structure problem, please
always take off the motherboard from chassis,
before adding or removing a heatsink kit.

The proper procedure to install the heatsink kit:

First, install the processor into the processor socket.

Insert the heatsink left side fix plate into the
processor socket left side fix hooks. Make sure the fit
is very tight. Check the photo on the left.

2-3

User’s Manual

Chapter 2

2-4

Insert a flat screwdriver into the middle slot of the
right side fix plate and push down. Then you can
push the fix plate over the socket hooks on the right
side. Check the photo on the left.

Check the photo on the left. You have finished the
heatsink installation.

Now hold the whole heatsink and slightly shake it,
make sure the buttom right side of the heaksink does
not contact the right side of the Socket (see bottom
picture). Otherwise, the processor die does not have
proper contact with the heatsink. This situation may
cause processor damage.

Remember to install the heatsink fan power cable to
the CPU fan header on the motherboard.

Now you can reinstall the motherboard back into the
chassis.

When all above procedures done, you can connect
the ATX power cable to the motherboard.

If you have different types of heatsink kit, please
refer to the manual that came with the heatsink kit.
The left photo shows another type of heatsink fix
plate design. The install sequences are still the same,
from right side to left side. Just remember that.

We strongly recommand you to buy a heatsink
with three holes in the fix plate. This will provide
the best stabability and won’t cause the Socket fix
hooks to be broken or damaged.

The left photo shows the bottom right side of the
heaksink in contact with the right side of the Socket.
In this situation, the processor die does not properly
contact the heatsink. If you start the computer at this
monent, it will immediately cause the processor
damage. Always check this place when you finish the
heatsink installation.

2-2. Installing the Motherboard to the Chassis

After you install the processor to the motherboard, you can start to fix the motherboard into the chassis.
Most computer chassis will have a base on which there will be many mounting holes that allows the
motherboard to be securely attached and at the same time, prevents short circuits. There are two ways to
attach the motherboard to the base of chassis:

! With studs
! With spacers

Please refer to figure 2-3, which shows the studs and spacers. There may be several types, but all look
like the figures below:

In principle, the best way to attach the motherboard is with studs.
Only if you are unable to do this should you attach the board
with spacers. Take a careful look at the motherboard and you
will see many mounting holes on it. Line these holes up with the
mounting holes on the base. If the holes line up and there are
screw holes this means you can attach the motherboard with
studs. If the holes line up and there are only slots, this means
you can only attach the motherboard with spacers. Take the tip

of the spacers and insert them into the slots.
After doing this to all the slots, you can slide
the motherboard into position aligned with the
slots. After the motherboard has been
positioned, check to make sure everything is
OK before putting the casing back on.

Figure 2-4 shows you the way to affix the
motherboard using studs or spacers.

Note

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are
no slots to attach the spacers, don’t worry, you can still attach the spacers to the mounting holes. Just
cut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with your
hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard
PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any the printed circuit wire or parts on the PCB that are near the fixing hole, otherwise it may damage
the board or cause board malfunctioning.

2-3. Installing System Memory

This motherboard provides two 184-pin DDR DIMM sites for memory expansion. The DDR DIMM
sockets support 8 M x 64 (64 MB), 16M x 64 (128 MB), 32 M x 64 (256 MB) and 64 M x 64 (512 MB)
or double density DDR DIMM modules. Minimum memory is 64 MB and the maximum memory is 1 GB
DDR SDRAM. There are two memory module sockets on the system board (for a total of four banks). In
order to create a memory array, following rules must be followed.

! The memory array is 64 or 72 bits wide. (Depending on with or without parity)
! For those modules, we suggest that you be populate DIMM1 to DIMM2 in order.
! Supports single and double density DDR DIMMs.

Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 2-5 to see what a 184-pin PC 1600 and PC
2100 DDR SDRAM module looks like.

Unlike installing SIMMs, DIMMs may be
“snapped” directly into the socket. Note: Certain
DDR DIMM sockets have minor physical differences.
If your module doesn't seem to fit, please do not
force it into the socket as you may damaged your
memory module or DDR DIMM socket.

The following procedure will show you how to
install a DDR DIMM module into a DDR DIMM
socket.

Step 1. Before you install the memory module,

Step 2. Remove the computer’s chassis cover.

Step 3. Before touching any electronic components,

64 MB ~ 512 MB

power cord from your computer.

make sure you first touch an unpainted,
grounded metal object to discharge any
static electricity stored on your clothing or
body.

NV7m Motherboard

Installing the Motherboard

DDR DIMM module will be plugged into the socket in one way only. Firmly press the DDR

DIMM module into DDR DIMM socket, making certain the module is completely seated in the
DDR DIMM socket.

Step 6. Once the DDR DIMM module has been installed, the installation is complete and the computer’s

cover can be replaced. Or you can continue to install other devices and add-on cards that are
mentioned in the following section.

Note

When you install a DDR DIMM module fully into the DDR DIMM socket, the eject tab should be
locked into the DDR DIMM module very firmly and fit into its indention on the both sides.

It is difficult to differentiate between the PC 1600 and PC 2100 DDR SDRAM modules from the exterior.
The only way you can identify them is to look at the sticker on the DDR SDRAM module. The sticker
will tell you which kind of structure module the DDR SDRAM is.

2-4. Connectors, Headers and Switches

Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are
usually connected one-by-one to connectors located on the motherboard. You need to carefully pay
attention to any connection orientation the cables may have and, if any, notice the position of the first pin
of the connector. In the explanations that follow, we will describe the significance of the first pin.

We will show you all of the connectors, headers and switches here, and tell you how to connect them.
Please pay attention and read the entire section for necessary information before attempting to finish all of
the hardware installation inside the computer chassis.

Figure 2-7 shows you all of the connectors and headers that we’ll discuss in the next section, you can use
this diagram to visually locate each connector and header we describe.

All connectors, headers and switches mentioned here, will depend on your system configuration. Some
features you may (or may not) have and need to connect or configure depending on the peripheral. If your
system doesn't have such add-on cards or switches you can ignore some special feature connectors.

Warning!!!

NVIDIA nForce chipset supports AGP 1.5V only, wrongfully plug an AGP 3.3V only AGP
graphic card on NV7m motherboard will burn the Crush 12 chipset and cause your NV7m
motherboard damaged.

Explaination: Most of the AGP cards golden finger is with a notch to identify AGP 3.3V or AGP

1.5V, an AGP graphic card without the notch means AGP 1.5V not compatible and can’t be inserted
into AGP slot fully. Very few AGP graphic cards it’s a 3.3V only AGP graphic card but with “1.5V
identify notch” golden finger! Such kind of abnormal golden finger will permit AGP graphic card
plug into NV7m motherboard then burn the chipset and cause motherboard damaged. Some AGP
graphic cards are with jumpers for switches to AGP 1.5V or 3.3V. Please DO MAKE SURE it’s
jumpers setting at 1.5V position before you insert it into NV7m motherboard.

First, let’s see the headers that NV7m uses, and what their functions are. We will show you all the
connectors and headers.

(1). ATXPWR1: ATX Power Input Connector

Attach the connector from the power supply to the ATXPWR1 connector here. Remember you have to
push the connector from the ATX power supply firmly to the end with the ATXPWR1 connector,
insuring that you have a good connection.

Note: Watch the pin position and the orientation.

NV7m Motherboard

Installing the Motherboard

Caution

If the power supply connectors are not properly attached to the ATX power supply, the power supply
or add-on cards may be damaged.

One end of AC power core connects to ATX power supply, and the other end (AC plug) will plug into
the wall outlet. Be aware that when facing the wall outlet, the round hole is in the middle. The right
side slot is called ground wire slot. It has a longer slot length than the left side slot. The left side slot is
called the live wire slot. You can use an electroscope to detect its polarity or you can use a voltage
meter to measure the voltage of both slot sides. If you insert an electroscope into the live wire slot, the
electroscope will light up. Using a voltage meter, you will find that the live wire slot will register a
higher voltage.

If you reverse the polarity of AC plug, it may affect the life of computer equipment, or cause an
electric shock when you touch the computer chassis. We suggest that you plug the computer AC plug
to a three-hole wall outlet for better safety and to avoid electric shock.

2-9

(2). CPUFAN1, CHAFAN1, PWRFAN1 and EXTFAN1 headers

Attach the connector from the processor fan to the
header named CPUFAN1 and connector from the front
chassis fan to the header CHAFAN1. Attach the
connector from the power fan to PWRFAN1 header
and connector from the back chassis fan to the header
EXTFAN1. You must attach the processor fan to the
processor, or your processor will work abnormally or
may be damaged by overheating. To prevent the
computer chassis internal temperature from getting too
high, also connect the chassis fan.

Note: Watch the pin position and the orientation
