Gigabyte GA-7N400V-L, GA-7N400V PRO2 User Manual

When you installing AGP card, please make sure the following notice
is fully understood and practiced. If your AGP card has "AGP 4X/8X
(1.5V) notch"(show below), please make sure your AGP card is AGP
4X/8X.

AGP 4X/8X notch

Caution: AGP 2X card is not supported by nVIDIA® nForce™ 2 IGP. You
might experience system unable to boot up normally. Please
insert an AGP Pro 4X/8X card.

Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X
mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X(1.5V) mode
by adjusting the jumper. The factory default for this card is 2X(3.3V). The
GA-7N400V Pro2 / GA-7N400V / GA-7N400V-L (or any AGP 4X/8X only)
motherboards might not function properly, if you install this card without
switching the jumper to 4X(1.5V) mode in it.

Example 2: Some ATi Rage 128 Pro graphics cards made by "Power Color",
the graphics card manufacturer & some SiS 305 cards, their golden finger is
compatible with 2X(3.3V) / 4X(1.5V) mode AGP slot, but they support
2X(3.3V) only. The GA-7N400V Pro2 / GA-7N400V / GA-7N400V-L (or any
AGP 4X/8X only) motherboards might not function properly, If you install this
card in it.

Note : Although Gigabyte's AG32S(G) graphics card is based on ATi Rage
128 Pro chip, the design of AG32S(G) is compliance with AGP 4X(1.5V)
specification. Therefore, AG32S(G) will work fine with nVIDIA® nForce2 IGP
based motherboards.

Before you install PCI cards, please remove the Dual BIOS label from PCI
slots if there is one.

Computer motherboards and expansion cards contain very delicate Integrated Circuit
(IC) chips. T o protect them against damage from static electricity, you should follow
some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do not have one, touch
both of your hands to a safely grounded object or to a metal object, such as the power supply
case.

3. Hold components by the edges and try not touch the IC chips, leads or connectors, or other
components.

4. Place components on a grounded antistatic pad or on the bag that came with the components
whenever the components are separated from the system.

5. Ensure that the A TX power supply is switched of f before you plug in or remove the A TX power
connector on the motherboard.

Installing the motherboard to the chassis...

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, do not become alarmed you can still attach the spacers to the mounting
holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful of
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 printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the
board or cause board malfunctioning.

(*) If this "ATX_12V connector" is not connected, system cannot boot.

Please set the CPU host frequency in accordance with your processor's specifications.
We don't recommend you to set the system bus frequency over the CPU's specification because
these specific bus frequencies are not the standard specifications for CPU, chipset and most of the
peripherals. Whether your system can run under these specific bus frequencies properly will
depend on your hardware configurations, including CPU, Chipsets, SDRAM, Cards…etc.

Step 3: Install Memory Modules

Before installing the memory modules, adhere to the following warning:

1.When DIMM LED is ON, do not install / remove DIMM from socket.

2.Please note that the DIMM module can only fit in one direction due to
the one notch. Wrong orientation will cause improper installation.
Please change the insert orientation.

The motherboard has 4 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. T o install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.

DDR Introduction

high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs
and system integrators.

SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck
by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge
of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM
clock frequency. With peak bandwidth of 2.664GB per second, DDR memory enables system OEMs
to build high performance and low latency DRAM subsystems that are suitable for servers, workstations,
high-end PC's and value desktop SMA systems.

1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM
socket. Then push it down.

3. Close the plastic clip at both edges of the DIMM sockets
to lock the DIMM module.
Reverse the installation steps when you wish to remove
the DIMM module.

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a

DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing

Dual Channel DDR:

GA-7N400V Pro2 / GA-7N400V / GA-7N400V-L support Dual Channel Technology. When Dual Channel
Technology is activated, the bandwidth of memory bus will be double the original one, with the fastest
speed at 5.3GB/s(DDR333) .
GA-7N400V Pro2 / GA-7N400V / GA-7N400V-L include 4 DIMM slots, and each Channel has 2 DIMMs
as following:

Channel A : DIMM 1, 2

Channel B : DIMM 3, 4
Below are the explanations:
If you want to operate the Dual Channel Technology, please note the following explanations
due to the limitation of nForce chipset specifications.

1. Only one DDR memory module is installed: The Dual Channel Technology can't

operate when only one DDR memory module is installed.

2. Two DDR memory modules are installed: The Dual Channel Technology will operate

when two memory modules are inserted individually into Channel A and B. If you install
two memory modules in the same channel, the Dual Channel Technology will not
operate.

3. Three or Four DDR memory modules are installed: Please follow figure 1 to achieve the

Dual Technology.

The following tables include all memory-installed combination types:
(Please note that those types not in the tables will not boot up.)
