Installing A Memory - Gigabyte GA-X79-UD3 User Manual

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.
DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install
DDR3 DIMMs on this motherboard.
A DDR3 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.
