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supportedmemoryspeedsandmemorymodules.)
• 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.

1-4-1 DualChannelMemoryConguration
This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory
isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.EnablingDual
Channel memory mode will double the original memory bandwidth.
ThefourDDR4memorysocketsaredividedintotwochannelsandeachchannelhastwomemorysocketsas
following:
ChannelA:DDR4_2,DDR4_4
ChannelB:DDR4_1,DDR4_3
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one 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 sockets.
