1-4 Special Features
Recovery from AC Power Loss
Basic I/O System (BIOS) provides a setting for you to determine how
the system will respond when AC power is lost and then restored to
the system. You can choose for the system to remain powered off, (in
which case you must press the power switch to turn it back on), or for
it to automatically return to a power-on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.
1-5 PC Health Monitoring
This section describes the PC health monitoring features of the board.
All have an onboard System Hardware Monitoring chip that supports PC
health monitoring. An onboard voltage monitor will scan these onboard
voltages continuously: +1.8V, +3.3V, +5V, +/- 12V, +3.3V Stby, +5V
Stby, VBAT, HT, Memory PCH Temperature, and System Temperature.
Once a voltage becomes unstable, a warning is given, or an error message is sent to the screen. The user can adjust the voltage thresholds
to dene the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
PC health monitoring in the BIOS can check the RPM status of the cooling fans. The onboard CPU and chassis fans are controlled by Thermal
Management via SIO.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time
and will turn on the thermal control fan whenever the CPU temperature
exceeds a user-dened threshold. The overheat circuitry runs independently from the CPU. Once the thermal sensor detects that the CPU
temperature is too high, it will automatically turn on the thermal fans to
prevent the CPU from overheating. The onboard chassis thermal circuitry
can monitor the overall system temperature and alert the user when the
chassis temperature is too high.
Note: To avoid possible system overheating, please be sure to
provide adequate airow to your system.
1-4
Chapter 1: Introduction
System Resource Alert
This feature is available when the system is used with SuperDoctor 5
in the Windows and Linux operating systems. SuperDoctor is used to
notify the user of certain system events. For example, you can also
congure SuperDoctor to provide you with warnings when the system
temperature, CPU temperatures, voltages and fan speeds go beyond
predened thresholds.
1-6 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI
specication denes a exible and abstract hardware interface that
provides a standard way to integrate power management features
throughout a PC system, including its hardware, operating system and
application software. This enables the system to automatically turn on
and off peripherals such as CD-ROMs, network cards, hard disk drives
and printers.
In addition to enabling operating system-directed power management,
ACPI also provides a generic system event mechanism for Plug and Play,
and an operating system-independent interface for conguration control.
ACPI leverages the Plug and Play BIOS data structures, while providing
a processor architecture-independent implementation that is compatible
with Windows 7, Windows 8, and Windows 2008 Operating Systems.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will
start to blink to indicate that the CPU is in suspend mode. When the user
presses any key, the CPU will wake up, and the LED will automatically
stop blinking and remain on.
1-5
Supermicro C7Z370-CG-IW Motherboard User’s Manual
1-7 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors
that have high CPU clock rates or overclocked processors.
This motherboard accommodates 24-pin ATX power supplies. Although
most power supplies generally meet the specications required by the
CPU, some are inadequate. In addition, the 12V 8-pin power connector
located at JPW2 is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.
Attention! To prevent damage to the power supply or motherboard, please use a power supply that contains a 24-pin and a
8-pin power connectors. Be sure to connect these connectors to
the 24-pin (JPW1) and the 8-pin (JPW2) power connectors on the
motherboard.
It is strongly recommended that you use a high quality power supply
that meets ATX power supply Specication 2.02 or above. It must also
be SSI compliant. (For more information, please refer to the web site
at http://www.ssiforum.org/). Additionally, in areas where noisy power
transmission is present, you may choose to install a line lter to shield
the computer from noise. It is recommended that you also install a power
surge protector to help avoid problems caused by power surges.
1-8 Super I/O
The Super I/O supports two high-speed, 16550 compatible serial communication ports (UARTs). Each UART includes a 16-byte send/receive FIFO,
a programmable baud rate generator, complete modem control capability
and a processor interrupt system. Both UARTs provide legacy speed with
baud rate of up to 115.2 Kbps as well as an advanced speed with baud
rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Con-
guration and Power Interface), which includes support of legacy and
ACPI power management through an SMI or SCI function pin. It also
features auto power management to reduce power consumption.

Towards the CPU
The C7Z370-CG-IW supports up to 32GB of Unbuffered (UDIMM) nonECC DDR4 memor y with speeds of up to 3733+(OC) in two 288-pin
memory slots. Populating these DIMM modules with a pair of memory
modules of the same type and same size will result in interleaved
memory, which will improve memory performance.
Note: Be sure to use memory modules of the same type, speed,
frequency on the motherboard. Mixing of memory modules of different types and speeds is not allowed.
For Microsoft Windows users: Microsoft implemented a design
change in the Windows XP with Service Pack 2 (SP2) and Win-
dows Vista. This change is specic to the behavior of Physical
Address Extension (PAE) mode which improves driver compatibility. For more information, please read the following article at
Microsoft’s Knowledge Base website at: http://support.micro-

Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in
the following order: DIMMA1 then DIMMB1.
• Always use DDR4 DIMM modules of the same size, type, and speed.
• Mixed DIMM speeds can be installed. However, all DIMMs will run at the
speed of the slowest DIMM.

2-5 Motherboard Installation
All motherboards have standard mounting holes to t different types of
chassis. Make sure that the locations of all the mounting holes for both
motherboard and chassis match. Although a chassis may have both plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure that the
metal standoffs click in or are screwed in tightly. Then use a screwdriver
to secure the motherboard onto the motherboard tray.

Fan Headers
Your motherboard has two 4-pin fan
headers (CPU_FAN1, SYS_FAN1). Although pins 1-3 of the fan headers are
backward compatible with the traditional
3-pin fans, we recommend the use 4-pin
fans to take advantage of the fan speed
control. This allows the fan speeds to
be automatically adjusted based on the
motherboard temperature. Refer to the
table on the right for pin denitions.

2-8 Jumper Settings
Explanation of Jumpers
To modify the operation of the motherboard, jumpers can be used to
choose between optional settings. Jumpers create shorts between two
pins to change the function of the connector. Pin 1 is identied with a
square solder pad on the printed circuit board.
Note: On two-pin jumpers, Closed means the jumper is on, and Open
means the jumper is off the pins.
2-28
Chapter 2: Installation
JCMOS
JCMOS is used to clear the saved system setup conguration stored in
the CMOS chip. To clear the contents of the CMOS using JCMOS, short
the two pins of JCMOS with a metallic conductor such as a athead
screwdriver. This will erase all user settings, revert everything to their
factory defaults, and then start the computer.
Watch Dog Timer Enable/Disable
Watch Dog (JWD1) is a system monitor
that can reboot the system when a software application hangs. Close pins 1 and
2 to reset the system if an application
hangs. Close pins 2 and 3 to generate a
non-maskable interrupt signal for the application that hangs. Refer to the table on
the right for jumper settings.

5. The battery on your motherboard may be old. Check to make sure
that it still supplies ~3VDC. If it does not, replace it with a new
one.
No Video
1. If the power is on, but you have no video--in this case, you will
need to remove all the add-on cards and cables rst.
2. Use the speaker to determine if any beep codes exist. (Refer to Appendix A for details on beep codes.)
3. Remove all memory modules and turn on the system. (If the
alarm is on, check the specications of memory modules, reset the
memory or try a different one.)
Memory Errors
1. Make sure that the DIMM modules are properly installed and fully
seated in the slots.
2. You should be using unbuffered Non-ECC DDR4 (up to 3733MHz
with overclocking) memory recommended by the manufacturer.
Also, it is recommended that you use the memory modules of the
same type and speed for all DIMMs in the system. Do not use
memory modules of different size, speed, and type on the motherboard.
3. Check for bad DIMM modules or slots by swapping modules between slots to see if you can locate the faulty ones.
4. Check the switch of 115V/230V power supply.
When the System is Losing the Setup Configuration
1. Please be sure to use a high quality power supply. A poor quality
power supply may cause the system to lose CMOS setup information. Refer to Section 1-7 for details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that
it still supplies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not x the Setup Conguration problem,
contact your vendor for repairs.
3-2 Technical Support Procedures
Before contacting Technical Support, please make sure that you have
followed all the steps listed below. Also, Note that as a motherboard
manufacturer, Supermicro does not sell directly to end users, so it is
best to rst check with your distributor or reseller for troubleshooting
services. They should know of any possible problem(s) with the specic
system conguration that was sold to you.
1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently
Asked Question' (FAQ) sections in this chapter or see the FAQs on
our website (http://www.supermicro.com/support/faqs/) before
contacting Technical Support.
2. BIOS upgrades can be downloaded from our website at (http://
www.supermicro.com/support/bios/).
Note: Not all BIOS can be ashed. Some cannot be ashed; it
depends on the boot block code of the BIOS.
3. If you've followed the instructions above to troubleshoot your
system, and still cannot resolve the problem, then contact Supermicro's technical support and provide them with the following information:
• Motherboard model and PCB revision number
• BIOS release date/version (this can be seen on the initial display when
your system rst boots up)
• System conguration
• An example of a Technical Support form is on our website at (http://
www.supermicro.com/support/contact.cfm).
4. Distributors: For immediate assistance, please have your account
number ready when placing a call to our technical support depart-
ment. We can be reached by e-mail at support@supermicro.com,

Supermicro C7Z370-CG-IW Motherboard User’s Manual
3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The C7Z370-CG-IW supports up to 32GB of unbuffered Non-
ECC DDR4. See Section 2-4 for details on installing memory.
Question: How do I update my BIOS?
Answer: We do NOT recommend that you upgrade your BIOS if you are
not experiencing any problems with your system. Updated BIOS les are
located on our website at http://www.supermicro.com/support/bios/.
Please check our BIOS warning message and the information on how
to update your BIOS on our web site. Select your motherboard model
and download the BIOS ROM le to your computer. Also, check the current BIOS revision to make sure that it is newer than your BIOS before
downloading. You may choose the zip le or the .exe le. If you choose
the zipped BIOS le, please unzip the BIOS le onto a bootable device
or a USB pen/thumb drive. To ash the BIOS, run the batch le named
"ami.bat" with the new BIOS ROM le from your bootable device or USB
pen/thumb drive. Use the following format:
F:\> ami.bat BIOS-ROM-lename.xxx <Enter>
Note: Always use the le named “ami.bat” to update the
BIOS, and insert a space between "ami.bat" and the lename.
The BIOS-ROM-lename will bear the motherboard name (i.e.,
C7Z370) and build version as the extension. For example,
"C7Z370.115". When completed, your system will automatically
reboot.
If you choose the .exe le, please run the .exe le under Windows to create the BIOS ash oppy disk. Insert the oppy disk
into the system you wish to ash the BIOS. Then, boot the system to the oppy disk. The BIOS utility will automatically ash
the BIOS without any prompts. Please note that this process
may take a few minutes to complete. Do not be concerned if
the screen is paused for a few minutes.
When the BIOS ashing screen is completed, the system will
reboot and will show “Press F1 or F2”. At this point, you will
need to load the BIOS defaults. Press <F1> to go to the BIOS
setup screen, and press <F9> to load the default settings. Next,
press <F10> to save and exit. The system will then reboot.
Attention! Do not shut down or reset the system while updating
the BIOS to prevent possible system boot failure!
