Hardware Installation

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 four 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fourDDR4

memory sockets are divided into four channels and each channel has one memory socket as following:

Channel A: DDR4_1_A

Channel B: DDR4_2_B

Channel C: DDR4_3_C

Channel D: DDR4_4_D

Note 1: If you are using a RDIMM memory, make sure it is a 1Rx8 one.

Note 2: To ensure memory compatibility, we do not recommend that you install RDIMM and UDIMM memory

at the same time.
