GA-M750SLI-DS4 Motherboard - 16 -
1-4 Installing the Memory
Read the following guidelines before you begin to install the memory:
•Make sure that the motherboard supports the memory. It is recommended that memory of
the same capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest memory support list.)
•Always turn off the computer and unplug the power cord from the power outlet before
installing the memory to prevent hardware damage.
•Memory modules have a foolproof design. A memory module can be installed in only one
direction. If you are unable to insert the memory, switch the direction.
Due to CPU limitation, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same
colored DDR2 sockets for optimum performance.
1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 memory sockets and supports Dual Channel
Technology. After the memory is installed, the BIOS will automatically detect the
specifications and capacity of the memory. Enabling Dual Channel memory mode
will double the original memory bandwidth.
The four DDR2 memory sockets are divided into two channels and each channel has two memory
sockets as following:
Channel 0: DDR2_1, DDR2_3
Channel 1: DDR2_2, DDR2_4

1-4-2 Installing a Memory
Before installing a memory module , make sure to turn off the computer and unplug
the power cord from the power outlet to prevent damage to the memory module.
DDR2 DIMMs are not compatible to DDR DIMMs. Be sure to install DDR2 DIMMs on
this motherboard.
A DDR2 memory module has a notch, so it can only fit in one direction. Follow the steps below to
correctly install your memory modules in the memory sockets.
Step 1:
Note the orientation of the memory module. Spread the retaining
clips at both ends of the memory socket. Place the memory
module on the socket. As indicated in the picture on the left,
place your fingers on the top edge of the memory, push down
on the memory and insert it vertically into the memory socket.
Step 2:
The clips at both ends of the socket will snap into place when
the memory module is securely inserted.
