1-3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of heat paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use,
otherwise overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the CPU specifications. It is not
recommended that the system bus frequency be set beyond hardware specifications
since it does not meet the required standards for the peripherals. If you wish to set
the frequency beyond the proper specifications, please do so according to your hard-
ware specifications including the CPU, graphics card, memory, hard drive, etc.

The motherboard supports DDRII memory modules, whereby BIOS will automatically detect memory
capacity and specifications. Memory modules are designed so that they can be inserted only in one direction.
The memory capacity used can differ with each slot.
Before installing the memory modules, please comply with the following conditions:
1. Please make sure that the memory used is supported by the motherboard. It is
recommended that memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer
power is switched off to prevent hardware damage.
3. Memory modules have a foolproof insertion design. A memory module can be installed
in only one direction. If you are unable to insert the module, please switch the direction.

Dual Channel Memory Configuration
The GA-N650SLI-DS4 supports the Dual Channel Technology. After operat-
ing the Dual Channel Technology, the bandwidth of memory bus will double.
The GA-N650SLI-DS4 includes 4 DIMM sockets, and each Channel has two
DIMM sockets as following:
Channel 0 : DDRII1, DDRII2
Channel 1 : DDRII3, DDRII4
If you want to operate the Dual Channel Technology, please note the following explanations
due to the limitation of Intel chipset specifications.
1. Dual Channel mode will not be enabled if only one DDRII memory module is installed.
2. To enable Dual Channel mode with two or four memory modules (it is recommended to
use memory modules of identical brand, size, chips, and speed), you must install them
into DIMM sockets of the same color.

computer.
2. Remove your computer's chassis cover, screws and slot bracket from the computer.
3. Press the expansion card firmly into expansion slot in motherboard.
4. Be sure the metal contacts on the card are indeed seated in the slot.
5. Replace the screw to secure the slot bracket of the expansion card.
6. Replace your computer's chassis cover.
7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.
8. Install related driver from the operating system.
Installing a PCI Express x16 expansion card:
To install a VGA card or to release an
installed card, users can also press the
latch on the back of the drawable bar as
the picture to the left shows.
Please carefully pull out the small white-
drawable bar at the end of the PCI Ex-
press x16 slot when you try to install/
uninstall the VGA card. Please align the
VGA card to the onboard PCI Express
x16 slot and press firmly down on the
slot. Make sure your VGA card is locked
by the small white-drawable bar.

1-6 Setup of an SLI (Scalable Link Interface) Configuration
The nVIDIA®nForce 650i SLI chipset offers blistering graphics performance with the ability to bridge two
nVIDIA®SLI-ready PCI ExpressTM graphics cards! The SLI design takes advantage of the increased
bandwidth of the PCI ExpressTM bus architecture, features hardware and software innovations within
nVIDIA®GPU (graphics processing unit) and the nVIDIA®nForce 650i SLI chipset. Together, the nVIDIA®
SLI technologies work seamlessly to allow two graphics cards to operate in parallel and share the work
and deliver heart-pounding PC performance. This section introduces steps to configure an SLI system
on the GA-N650SLI-DS4 motherboard.
Before You Begin--
I. Understanding the components:
The SLI bridge connector
The SLI bridge connector is used to bridge two SLI-capable graphics
cards to enable SLI operation.
The SLI switch module
Normal Mode (default): In Normal Mode, the first PCIe x16 slot
(PCIE_16_1) operates at up to x16, whereas the second PCIe x16
slot becomes unavailable.
SLI Mode: In SLI Mode, you may use the two PCIe x16 slots for the
following functions:
1. SLI Configuration: Install two SLI-capable PCIe x16 graphics cards of the same model to
enable SLI function.
2. Independent PCI x8 slots: Use the two PCIe x16 slots as two independent PCIe x8 slots.
SLI Switch Module
SLI Bridge Connector
II. Power Requirements:
Before installation, assure that the power supply you use is able to provide sufficient power to fully
support an SLI configuration and other components in your system. We recommend a power supply
that provides at least 20A 5V and 12V current and a minimum of 400W wattage. Note that the exact
power requirements will depend on your overall system configurations.
III. Supported Operating Systems:
Only Windows XP operating system is currently supported by the nVIDIA®SLI technology.
Enabling SLI Operation
Step 1: Gently spread the retaining clips of the socket and the module
will be released. Hold the module by the edges and lift it
away from the socket.
Setting the SLI switch module:
The SLI switch module is set to Normal Mode operation by factory default, so the first step is to take out the
module from the socket, turn it around and insert it in the SLI Mode direction.
Both of the PCIe x16 slots will be unavailable when the SLI switch module is removed from
the motherboard.

GA-N650SLI-DS4 Motherboard - 18 -
English
Step 2: Insert the SLI bridge into the SLI gold edge connectors on top
of both cards. Make sure the two mini female slots on the
bridge connector securely fit onto the SLI gold edge connetors.
Connecting Two Graphics Cards:
Step 1: Observe the steps in section "1-5 Installation of Expansion
Cards" and install two SLI-ready graphics cards of the same
model in the PCIE_16_1 and PCIE_16_2 slots.
Step 2: Turn the module to the SLI Mode. Align the small notch at the
top edge of the module with the key in the socket. Insert the
top edge of the module into the socket. Make sure the gold
edge connectors are fully inserted.
Step 3: Gently press down on the two ends of the module until it is
locked in place by the socket clips. (You should hear a "click"
when the module fits in.)
Step 3: In order to securely fix the bridge connector between the two
cards, you must install the retention bracket included with the
motherboard and secure the retention bracket to the chassis
back panel with a screw.
Place this section on the top
of the bridge connector.

English
Graphics Card Driver Setting:
Step 1: After installing graphics card driver in operating system, right-
click the NVIDIA icon in your system tray and then select
NVIDIA Display. The NVIDIA control panel will appear.
Step 4: Plug the display cable into either one of the two graphics
cards for display output. If you plug the display cable into the
card on the PCIE_16_1 slot, make sure to set Init Display
First in BIOS Setup to PEG; if you plug the display cable
into the card on the PCIE_16_2 slot, set Init Display
First to PEG(Slot2).
Step 2: Select SLI multi-GPU from the side menu and then
select the Enable SLI multi-GPU checkbox in the SLI
multi-GPU dialog box. System will restart after you
click Apply. Then the SLI configuration is completed.
(Note) For more information about software configurations for SLI, refer to the user's manual for your
graphics card.
