1-3 Installing the CPU
Please visit GIGABYTE's website for details on 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.
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: DDR4_A1, DDR4_A2
Channel B: DDR4_B1, DDR4_B2
Read the following guidelines before you begin to install the CPU:
Make sure that the motherboard supports the CPU.
(Go to GIGABYTE's website for the latest CPU support list.)
Always turn off the computer and unplug the power cord from the power outlet before installing the
CPU to prevent hardware damage.
Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly.
Apply an even and thin layer of thermal grease on the surface of the CPU.
Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage
of the CPU may occur.
Set the CPU host frequency in accordance with the CPU specications. It is not recommended
that the system bus frequency be set beyond hardware specications since it does not meet the
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specications, please do so according to your hardware specications including the CPU, graphics
card, memory, hard drive, etc.
Installing the CPU
Locate the pin one (denoted by a small triangle) of the CPU socket and the CPU. Once the CPU is positioned
into its socket, place one nger down on the middle of the CPU, lowering the locking lever and latching it into
the fully locked position.
