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 C9Z390-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, removing 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. Remove the WARNING plastic cap from the socket.

2. Press and move the locking lever to the unlocked position.

DIMMs into the memory slots,
starting with DIMMA1, DIMMB1.
For the system to work properly,
please use the memory modules
of the same type and speed.

2. Push the release tab outwards
on the end of the DIMM slot to
unlock it.

3. Align the key of the DIMM mod­ule with the receptive point on the
memory slot.

4. Align the notches on both ends of
the module against the receptive
points on the ends of the slot.

5. Use two thumbs together to press
the notches on both ends of the
module straight down into the slot
until the module snaps into place.

Chapter 2: Installation

Memory Support

The C9Z390-CG-IW supports up to 32GB of Unbuffered (UDIMM) non­ECC DDR4 memory with speeds of up to 4000+MHz (OC) in four 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.

Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated
in the following order: DIMMA1, DIMMB1.

• Always use DDR4 DIMM modules of the same size and type.

• 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

The motherboard has two 4-pin fan head­ers (CPU_FAN1, SYS_FAN1). Although
pins 1-3 of the system fan headers are
backward compatible with the traditional
3-pin fans, we recommend the use of
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.

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.

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 C9Z390-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 3866 if
overclocked) MHz 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 sizes, speeds, and types.

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 Conguration 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 specic
system conguration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The C9Z390-CG-IW supports up to 32GB of unbuffered Non-

ECC U-DIMM 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 inse r t a spa ce be twe en "ami.bat" and the l ename. The BI­OS - ROM-  lenam e will bea r th e motherbo a r d name (i .e., CZ39 0)

and build version as the extension. For example, "C9Z390.115".
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.
