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 dene 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-dened 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 airow 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
congure SuperDoctor to provide you with warnings when the system
temperature, CPU temperatures, voltages and fan speeds go beyond
predened thresholds.

1-6 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI
specication denes 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 conguration 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 specications 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 Specication 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.

2-2 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic com ponents. To avoid damaging your system board, it is important to handle it very
carefully. The following measures are generally sufcient to protect your
equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic bag.
• Handle the board by its edges only; do not touch its components, peripheral chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard and peripherals back into their antistatic bags when not in use.
• For grounding purposes, make sure your computer chassis provides excellent conductivity between the power supply, the case, the mount­ing fasteners and the motherboard.
• Use only the correct type of onboard CMOS battery. Do not install the onboard battery upside down to avoid possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static dam­age. When unpacking the board, make sure that the person handling it is static protected.
2-2
Chapter 2: Installation

2-3 Processor and Heatsink Installation

Attention! When handling the processor package, avoid placing direct pressure on the label area of the fan.
Important:
Always connect the power cord last, and always remove it before adding, re-
moving or changing any hardware components. Make sure that you install the
processor into the CPU socket before you install the CPU heatsink.
If you buy a CPU separately, make sure that you use an Intel-certied multi-
directional heatsink only.
Make sure to install the system board into the chassis before you install the
CPU heatsink.
When receiving a server board without a processor pre-installed, make sure that
the plastic CPU socket cap is in place and none of the socket pins are bent;
otherwise, contact your retailer immediately.
Refer to the Supermicro website for updates on CPU support.

Installing the Processor

1. Press the load lever to release the load plate, which covers the CPU socket, from its locked position.

Installing an Active CPU Heatsink Fan

1. Locate the CPU Fan power con­nector on the motherboard. (Refer to the layout on the right for the CPU Fan location.)
2. Position the heatsink so that the heatsink fan wires are clos­est to the CPU fan power con­nector and are not interfered with other components.
3. Inspect the CPU Fan wires to make sure that the wires are routed through the bottom of the heatsink.
4. Remove the thin layer of the protective lm from the heat­sink.
Attention! CPU overheating may
occur if the protective lm is not
removed from the heatsink.
Thermal Grease
Heatsink Fins
5. Apply the proper amount of thermal grease on the CPU.
Note: If your heatsink came with a thermal pad, please ignore this step.
6. If necessary, rearrange the wires to make sure that the wires are not pinched between the heatsink and the CPU. Also make sure to keep clearance between the fan wires and the
ns of the heatsink.
Note: Graphic drawings included in this manual are for reference only. They might look different from the components installed in your system.
2-6
7. Align the four heatsink fasteners with the mounting holes on the motherboard. Gently push the pairs of diagonal fasteners (#1 & #2, then #3 & #4) into the mounting holes until you hear a click. Also, make sure to orient each fastener so that the narrow end of the groove is pointing outward.
8. Once all four fasteners are securely inserted into the mounting holes, and the heatsink is properly installed on the motherboard, connect the heatsink fan wires to the CPU Fan connector.

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 specic 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-

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 denitions.
Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the ap­propriate cable from the chassis to inform you of a chassis intrusion when the chassis is opened.

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 identied 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 conguration 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.

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all of the procedures below and still need assistance, refer to the ‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter. Always disconnect the AC power cord before adding, changing or installing any hardware components.

Before Power On

1. Make sure that the Standby PWR LED is not on. (Note: If it is on, the onboard power is on. Be sure to unplug the power cable before installing or removing the components.)
2. Make sure that there are no short circuits between the motherboard and chassis.
3. Disconnect all ribbon/wire cables from the motherboard, including those for the keyboard and mouse. Also, be sure to remove all add­on cards.
4. Install a CPU and heatsink (be sure that it is fully seated) and then connect the chassis speaker and the power LED to the mother­board. Check all jumper settings as well.

No Power

1. Make sure that there are no short circuits between the motherboard and chassis.
2. Make sure that all jumpers are set to their default positions.
3. Check if the 115V/230V switch on the power supply is properly set.
4. Turn the power switch on and off to test the system.
3-1
Supermicro C7Z370-CG-IW Motherboard User’s Manual
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 specications 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.

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.
