2-4 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.
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 memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR5_A1j/DDR4_A1kl, DDR5_A2j/DDR4_A2kl
Channel B: DDR5_B1j/DDR4_B1kl, DDR5_B2j/DDR4_B2kl
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.
When installing a single memory module, we recommend that you install it in the DDR5_A2j/
DDR4_A2kl or DDR5_B2j/DDR4_B2kl socket.
