Gigabyte Z170n-gaming 5 Manual

							Dual	Channel	Memory	Configuration
This motherboard provides two memory sockets and supports Dual Channel Technology. After the memory 
is  installed,  the  BIOS  will  automatically  detect  the  specifications  and  capacity  of  the  memory.  Enabling  Dual 
Channel memory mode will double the original memory bandwidth.
The two memory sockets are divided into two channels:
 Channel A: DDR4_1
 Channel B: DDR4_2
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 install\
ed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of 
the same capacity, brand, speed, and chips be used.
1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion c\
ard:
 •Make sure the motherboard supports the expansion card. Carefully read the manual that came 
with your expansion card.
 •Always turn off the computer and unplug the power cord from the power outlet before installing an 
expansion card to prevent hardware damage.

Read the following guidelines before connecting external devices:
 •First make sure your devices are compliant with the connectors you wish \
to connect.
 •Before installing the devices, be sure to turn off the devices and your computer. Unplug the power 
cord from the power outlet to prevent damage to the devices.
 •After installing the device and before turning on the computer, make sure the device cable has 
been securely attached to the connector on the motherboard.

							3/4) CPU_FAN/SYS_FAN (Fan Headers)
  All fan headers on this motherboard are 4-pin. Most fan headers possess \
a foolproof insertion design. 
When connecting a fan cable, be sure to connect it in the correct orient\
ation (the black connector wire is 
the ground wire). The speed control function requires the use of a fan with fan speed control design. For 
optimum heat dissipation, it is recommended that a system fan be install\
ed inside the chassis.

1/2) ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
  With the use of the power connector, the power supply can supply enough stable power to all the components 
on the motherboard. Before connecting the power connector, first make sure the power supply is turned 
off and all devices are properly installed. The power connector possesses a foolproof design. Connect the 
power supply cable to the power connector in the correct orientation.
 The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, 
the computer will not start.To meet expansion requirements, it is recommended that a power supply that can withstand high 
power consumption be used (500W or greater). If a power supply is used that does not provide the 
required power, the result can lead to an unstable or unbootable system.

BAT (Battery)
  The battery provides power to keep the values (such as BIOS configurations, date, and time information) 
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low 
level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:1. Turn off your computer and unplug the power cord.2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.) 3. Replace the battery.4. Plug in the power cord and restart your computer.
 •Always turn off your computer and unplug the power cord before replacing the battery.
 •Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with 
an incorrect model.
 •Contact the place of purchase or local dealer if you are not able to rep\
lace the battery by yourself 
or uncertain about the battery model.
 •When installing the battery, note the orientation of the positive side (+) and the negative side (-) 
of the battery (the positive side should face up).
 •Used batteries must be handled in accordance with local environmental re\
gulations.
To enable hot-plugging for the SATA ports, refer to Chapter 2, "BIOS Setup," "Peripherals\SATA 
Configuration," for more information.

8) M.2 (M.2 Socket 3 Connector)
  The M.2 connector supports M.2 SATA SSDs and M.2 PCIe SSDs and support RAID configuration through 
the Intel® Chipset. Please note that an M.2 PCIe SSD cannot be used to create a RAID set either with an 
M.2 SATA SSD or a SATA hard drive and can only be used to build a RAID set with UEFI. Refer to Chapter 
3, "Configuring a RAID Set," for instructions on configuring a RAID array .
Follow the steps below to correctly install an M.2 SSD in the M.2 connec\
tor.
Step 1:
Use a screw driver to unfasten the screw and nut from the motherboard. Locat\
e the proper mounting hole 
for the M.2 SSD to be installed and then screw the nut first.
Step 2:
Slide the M.2 SSD into the connector at an angle.
Step 3:
Press the M.2 SSD down and then secure it with the screw.

							Chapter 2 BIOS Setup
 •Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction. •It is recommended that you not alter the default settings (unless you n\
eed to) to prevent system instability or other unexpected results. Inadequately altering the settings may result in system's failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values. (Refer to \
the "Load Optimized Defaults" section in this chapter or introductions of the battery/clear CMOS jumper in Chapter 1 for how to clear the CMOS \
values.)
BIOS (Basic Input and Output System) records hardware parameters of th\
e system in the CMOS on the 
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup, 
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows 
the user to modify basic system configuration settings or to activate certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to 
keep the configuration values in the CMOS.
To access the BIOS Setup program, press the  key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
 •Q-Flash allows the user to quickly and easily upgrade or back up BIOS wi\
thout entering the operating system.
 •@BIOS is a Windows-based utility that searches and downloads the latest \
version of BIOS from the Internet 
and updates the BIOS.
2-1 Startup Screen
The following startup Logo screen will appear when the computer boots.
(Sample BIOS Version: F1h)
Function Keys
 •When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults. •The BIOS Setup menus described in this chapter are for reference only an\
d may differ by BIOS version.
On the main menu of the BIOS Setup program, press arrow keys to move amo\
ng the items and press  
to accept or enter a sub-menu. Or you can use your mouse to select the i\
tem you want.
