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.

This motherboard provides eight DDR4 memory sockets and supports 4 Channel Technology. After the memory
isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.TheeightDDR4
memory sockets are divided into four channels and each channel has two memory sockets as following:
Channel A: DDR4_1_1A, DDR4_2_2A
Channel B: DDR4_3_1B, DDR4_4_2B
Channel C: DDR4_5_1C, DDR4_6_2C
Channel D: DDR4_7_1D, DDR4_8_2D
DDR4_1_1A DDR4_3_1B DDR4_7_1D DDR4_5_1C DDR4_8_2D DDR4_6_2C DDR4_2_2A DDR4_4_2B
