Installing A Memory - Gigabyte GA-X99-UD4P 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. DDR4 and DDR3
DIMMs are not compatible to each other or DDR2 DIMMs. Be sure to install DDR4 DIMMs on
this motherboard.
A DDR4 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 clip
at the right end 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 clip at the right end of the socket will snap into place when the
memory module is securely inserted.
