Gigabyte C621-SD8 (rev. 1.0) [11/46] Channelmemoryconfiguration

Due to CPU limitations, read the following guidelines before installing the memory in 4 Channel mode.

1. 4 Channel mode cannot be enabled if only one memory module is installed.

2. When enabling 4 Channel mode with two or four memory modules, it is recommended that memory of

the same capacity, brand, speed, and chips be used.

4ChannelMemoryConguration

This motherboard 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:

• 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.
