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.

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
