User manual GIGABYTE GA-7N400-L

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® nForceTM 2 Ultra 400. 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-7N400 Pro2 / GA-7N400 / GA-7N400-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-7N400 Pro2 / GA-7N400 / GA-7N400-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 Ultra 400 based motherboards. Before you install PCI cards, please remove the Dual BIOS label from PCI slots if there is one. 7n400Pro2_1002_f.p65 1 2003/7/4, ¤U¤È 03:21 The author assumes no responsibility for any errors or omissions that may appear in this document nor does the author make a commitment to update the information contained herein.

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer. Unplug your computer when working on the inside. 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. Hold components by the edges and try not touch the IC chips, leads or connectors, or other components. Place components on a grounded antistatic pad or on the bag that came with the components whenever the components are separated from the system. Ensure that the ATX power supply is switched off before you plug in or remove the ATX 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. j For GA-7N400 Pro2 only. k For GA-7N400 only. l For GA-7N400-L only.

DDR Introduction Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs and system integrators. DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing 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.

When Dual Channel Technology is activated, the bandwidth of memory bus will be double the original one, with the fastest speed at 6.4GB/s(DDR400) . GA-7N400 Pro2 / GA-7N400 / GA-7N400-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 Intel 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.) l Figure 1: Dual Channel Technology (DS: Double Side, SS: Single Side) DIMM 1 2 memory modules DS/SS X DS/SS X 3 memory modules DS/SS DS/SS X DS/SS 4 memory modules DS/SS DIMM 2 X DS/SS X DS/SS DS/SS DS/SS DS/SS X DS/SS DIMM 3 DS/SS DS/SS X X DS/SS X SS SS SS DIMM 4 X X DS DS X DS SS SS SS English l Figure 2: Non Dual Channel Technology (DS: Double Side, SS: Single Side) DIMM 1 1 memory module DS/SS X X X 2 memory modules DS/SS X DIMM 2 X DS/SS X X DS/SS X DIMM 3 X X DS/SS X X SS DIMM 4 X X X DS X SS If memories are inserted on dimm3 and dimm4 at the same time, please note that the memories must be exactly identical in device, type, size and single side.
