Chapter 1: Introduction

1-2 Chipset and Processor Features Overview

Built upon the functionalit y and t he capabilit y of the Intel 5100 chipset , the X 7DCL-

3/X7DCL-i motherboard provides the performance and feature set required for

dual processor-based high-end servers with conguration options optimized for

intensive computing, high energy-efciency and complex business applications.

The 5100 chipset supports single or dual Intel Xeon 64-bit Quad Core/Dual Core

5400/5300/5200/5100 Series processors with front side bus speeds of up to 1.333

GHz. The chipset consists of the 5100 Memor y Controller Hub (MCH), Intel I/O

Controller Hub (ICH9R) and the I/O subsystem.

The 5100 Memory Controller Hub (MCH)

The Intel 5100 MCH chip is designed for symmetric multiprocessing across two

independent front side bus interfaces. Each front side bus uses a 64-bit wide,

1066/1333 MTS data bus capable of transferring data at 8.5/10.6 GB/s for a total

bandwidth of 17/21.3 GB/s. The MCH supports a 36-bit wide address bus and up

to six DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capac-

ity of up to 32 GB.

The 5100 MCH also provides six x4 PCI-Express interfaces and one x4 DMI

Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bi-

directional bandwidth if congured as a x8 port, or 2 GB/s bi-directional bandwidth

if congured as a x4 port.

The Ninth Generation I/O Controller Hub (ICH9)

The I/O Controller ICH9R provides the data buffering and interface arbitration

required for the system to operate efciently. It also provides the bandwidth needed

for the system to maintain its peak performance. The Direct Media Inter face (DMI)

provides the connection between the MCH and the ICH9R. The ICH9R suppor ts

up to six PCI-Express x1 slots, six Serial ATA ports and twelve USB 2.0 por ts.

In addition, the ICH9R offers the Intel Matrix Storage Technology which provides

various RAID options for data protection and rapid data access. It also supports the

next generation of client management through the use of PROActive technology in

conjunction with Intel's next generation Gigabit Ethernet controllers.

X7DCL-3/X7DCL-i User's Manual

1-3 Special Features

Recovery from AC Power Loss

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 hit the power switch to turn it back

on) or for it to automatically return to a power-on state. See the Power Lost Control

setting in the Advanced BIOS Setup section to change this setting. The default

setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DCL-3/X7DCL-

i. All have an onboard System Hardware Monitor chip that supports PC health

monitoring.

Onboard Voltage Monitors

An onboard voltage monitor will scan for the CPU Cores, Chipset Voltage, +1.8V,

+3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and VBAT continuously.

Once a voltage becomes unstable, a warning is given or an error message is sent

to the screen. Users can adjust the voltage thresholds to dene the sensitivity

of the voltage monitor.

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management via BIOS (under

Hardware Monitoring in the Advanced Setting).

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 it detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, if the system is running low

on virtual memory and there is insufcient hard drive space for saving the data,

you can be alerted of the potential problem. You can also congure Supero Doctor

to provide you with warnings when the system temperature goes beyond a pre-

dened range.

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion 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. This also includes consumer devices connected to the PC

such as VCRs, TVs, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI

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 2000, Windows XP and Windows

2003 Servers.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

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.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button to make the system enter a SoftOff state. The monitor will be

suspended and the hard drive will spin down. Pressing the power button again

will cause the whole system to wake-up. During the SoftOff state, the ATX power

supply provides power to keep the required circuitry in the system "alive". In case

the system malfunctions and you want to turn off the power, just press and hold

the power button for 4 seconds. This option can be set in the Power section of the

BIOS Setup routine.

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the Standby or Off state. Note that external modem ring-on

can only be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN is dened as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN trafc is kept

1-11

X7DCL-3/X7DCL-i User's Manual

to a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.

1-6 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.

The X7DCL-3/X7DCL-i can only accommodate 24-pin ATX power supply. Although

most power supplies generally meet the specications required by the motherboard,

some are inadequate. You should use one that will supply at least 400W of power.

In addition, the 12V 8-pin is also required for adequate power supply to the CPU.

Also your power supply must supply 1.5A for the Ethernet ports.

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 (info

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.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock generator,

drive interface control logic and interrupt and DMA logic. The wide range of functions

integrated onto the Super I/O greatly reduces the number of components required

for interfacing with oppy disk drives. The Super I/O supports 360 K, 720 K, 1.2

M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or

1 Mb/s. It also provides two high-speed, 16550 compatible serial communication

ports (UARTs). 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 supports one PC-compatible printer port (SPP), Bi-directional Printer

Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).

1-12

Chapter 1: Introduction

The Super I/O provides functions that comply with ACPI (Advanced Conguration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through an SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

Electro-Static Discharge (ESD) can damage electronic com ponents. To prevent

damage to your system board, it is important to handle it very carefully. The fol-

lowing 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 as specied by the

manufacturer. Do not install the onboard battery upside down to avoid possible

explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid st atic damage. When

unpacking the board, make sure the person handling it is static protected.

2-2 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing direct pressure

on the label area of the fan.

Notes:

Always connect the power cord last and always remove it before adding, re-•

moving or changing any components. Make sure that you install the processor

into the CPU socket before you install the CPU heatsink.

Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly. •

If you buy a CPU separately, make sure that you use only Intel-certied multi-

directional heatsink and fan.

Make sure to install the motherboard into the chassis before you install the •

CPU heatsink and fan.

When purchasing a motherboard with an LGA 771 CPU Socket, make sure •

that the CPU plastic cap is in place, and none of the CPU Socket pins are

bent; otherwise, contact the retailer immediately.

Refer to the Chipset/MB Features Section for more details on CPU support.•

Mounting the Motherboard in the Chassis

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. Make sure that the metal standoffs click in or are screwed in

tigh tly. Then, use a screwdriver to secure the motherboard onto the motherboard

tray. (Note: some components are very close to the mounting holes. Please take

precautionary measures to prevent damage done to these components when you

install the motherboard into the chassis.)

Caution: To avoid damaging the motherboard and its components, please do

not use a force greater than 8 lb/inch on each mounting screw during mother-

board installation.

2-3 Installing DIMMs

Note: Check the SuperMicro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also note that the

memory is interleaved to improve performance.

DIMM Installation

1. Insert the desired number of DIMMs into the memory slots, starting with DIMM

#1A. The memory scheme is interleaved, so you must install two modules

at a time, beginning with DIMM 1A, DIMM 2A, then DIMM 1B, DIMM 2B, and

DIMM 1C, DIMM 2C. (See the Memory Installation Table Below.)

2. Insert each DIMM module vertically into its slot. Pay attention to the notch along

the bottom of the module to prevent inserting the DIMM module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the slot.

Repeat for all modules (See step 1 above.)

(Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be
populated. ii. Both Registered ECC DDR2 667MHz and 533 MHz DIMMs are supported;
however, you need to use the memory modules of the same speed and of the same type on
a motherboard. iii. For memory to work properly, you need to follow the restrictions listed
above. )

Memory Support

The X7DCL-3/X7DCL-i supports up to 48 GB Single-Rank/Dual Rank, Registered

ECC DDR2 667/533 in 6 DIMMs (The amount and type of memory supported is

dependent on the PCB revision. See Note 1 Below). Populating DIMM slots with

pairs of memory modules of the same size and same type will result in Inter-

leaved Memory which will improve memory performance.

Note 1: For the PCB Rev. 1.1 motherboard, Slots 1A and 2A support Dual-Rank

modules; however, Slots 1B, 2B, 1C and 2C support Single- Rank memory only

(Maximum of 32 GB). The PCB Rev. 1.1a board supports 6 Dual-Rank or 6 Single-

Rank modules (Maximum of 48 GB).

Note 2: Due to OS limitations, some operating systems may not show more than

4 GB of memor y.

Note 3: D ue t o mem ory a lloc ati o n to sys tem d evi c e s, m emory r e main ing ava ilable

for operational use will be reduced when 4 GB of RAM is used. The reduction in

memory availability is disproportional. (Refer to the following Memory Availability

Table for details. For Microsoft Windows users: Microsoft implemented a design

change in Windows XP with Service Pack 2 (SP2) and Windows Vista. This change

is specic to the Physical Address Extension (PAE) mode behavior which improves

driver compatibility. For more information, please read the following article at Micro-

Fan Headers

The X7DCL-3/X7DCL-i has four chassis/

system fan headers (Fan3 to Fan6), and

two CPU Fans (Fans 1/2). All these fans

are 4-p in fans. However, Pins 1-3 of the fa n

headers are backward compatible with the

traditional 3 -pin fans. See the table on the

right for pin denitions. Note: The onboard

fan speeds are cont rolled by Thermal Man-

agement via BIOS Hardware Monitoring in
the Advanced Setting. (The default setting

is Disabled.) Please use all 3-pin fans or

all 4-pin fans on the motherboard.

Chassis Intrusion

A Chassis Intrusion header is located at

JL1 on the motherboard. Attach an appro -

priate cable from the chassis to inform you

of a chassis intrusion when the chassis is

opened.

Alarm Reset

If three power supplies are installed,

the system will notify you when any of

the three power modules fails. Con-

nect JAR1 to a micro-switch to turn

off the alarm that is activated when a

power module fails. See the table on

Fault Detect

The system ca n noti fy you in the

event of a power supply failure. This

feature is available when three power

supply units are installed in the chas-

sis with one acting as a backup. If you

only have one or two power supply

units installed, you should disable

this (the default setting) with JPWF1

to prevent false alarms.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper " consists of contact

pads to prevent the accidental clearing of CMOS. To clear CMOS, use a metal

object such as a small screwdriver to touch both pads at the same time to short

the connection. Always remove the AC power cord from the system before clear-

ing CMOS.

Note: For an ATX power supply, you must completely shut down the system,

remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog

Watch Dog is a system monitor that can reboot

the system when a software application hangs.

Close pins 1-2 to reset the system if an applica-

tion hangs. Close pins 2-3 to generate a non-

maskable interrupt signal for the application that

hangs. See the table on the right for jumper set-

tings. Watch Dog must also be enabled in the

BIOS.

Troubleshooting

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.

Note: Always disconnect the power cord before adding, changing or install-

ing any hardware components.

Before Power On

Make sure that there are no short circuits between the motherboard and the 1.

chassis.

Disconnect all ribbon/wire cables from the motherboard, including those for 2.

the keyboard and mouse. Remove all add-on cards.

Install a CPU in CPU Socket and connect the chassis speaker and the power 3.

LED to the motherboard. (Make sure that the CPU is properly seated. Be sure

to check all jumper settings as well.)

No Power

Make sure that there are no short circuits between the motherboard and the 1.

chassis.

Make sure that all jumpers are set to their default positions. 2.

Make sure that the 115V/230V switch on the power supply is properly set.3.

Turn the power switch on and of f to test the system. The battery on your 4.

motherboard may be old. Check to verify that it still supplies ~3VDC. If it
does not, replace it with a new one.

No Video

If the power is on but you have no video, remove all the add-on cards and 1.

cables.

Use the speaker to determine if any beep codes exist. Refer to the Appendix 2.

for details on beep codes.

LosingtheSystem’sSetupConguration

Make sure that you are using a high quality power supply. A poor quality 1.

power supply may cause the system to lose the CMOS setup information.

Refer to Section 1-6 for details on recommended power supplies.

The battery on your motherboard may be old. Check to verify that it still 2.

3-1

X7DCL-3/X7DCL-i User's Manual

supplies ~3VDC. If it does not, replace it with a new one.

If the above steps do not x the Setup Conguration problem, contact your 3.

vendor for repairs.

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

Make sure the DIMM modules are properly and fully installed. Check if 1.

DIMMs of different speeds or types have been installed. Also make sure that

the BIOS setup is congured for the fastest speed of R AM used.

It is recommended to use the same R AM speed for all DIMMs in the system. 2.

Make sure you are using the correct type of Single-Rank, Registered ECC

DDR2 667/533 SDR AM (recommended by the manufacturer.)

Check for bad DIMM modules or slots by swapping a single module between 3.

four slots and noting the results. Make sure all memory modules are fully

seated in their slots. As an interleaved memory scheme is used, you must

install two modules at a time, beginning with DIMM 1A, then DIMM 2 A, and

so on (see Section 2-3). Check the position of the 115V/230V switch on the

power supply.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a motherboard manufacturer, Super Micro does not sell directly to end-us-

ers, 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.

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

Question' (FAQ) sections in this chapter or see the FAQs on our web site (http://

www.supermicro.com/support/faqs/) before contacting Technical Support.

BIOS upgrades can be downloaded from our web site at http://www.supermicro.2.

com/support/bios/.

If you still cannot resolve the problem, include the following information when 3.

contacting Super Micro for technical support:

Motherboard model and PCB revision number•

BIOS release date/version (this can be seen on the initial display when your •

system rst boots up)

3-2

Chapter 3: Troubleshooting

System conguration•

An example of a Technical Support form is on our web site at http://ww w.•

supermicro.com/support/contact.cfm/.

Distributors: For immediate assistance, please have your account number •

ready when placing a call to our technical support department. We can be

reached by e-mail at [e-mail] or by fax at: [phone],

option 2.

3-3 Frequently Asked Questions

Question: What are the various types of memory that my motherboard can

support?

Answer: The X7DCL-3/X7DCL-i has six 240-pin DIMM slots that support Single-

Rank, Registered ECC DDR2 667/533 SDRAM modules. It is strongly recom-

mended that you do not mix memory modules of different speeds and sizes. (See

Chapter 2 for detailed Information.)

Question: Why does Microsoft Windows XP (SP2) and Windows Vista show

less memory than what is physically installed?

Answer: Microsoft implemented a design change in Windows XP with Service

Pack 2 (SP2) and Windows Vista. This change is specic to the Physical Address

Extension (PAE) mode behavior which improves driver compatibility. For more in-

formation, please read the following article at Microsoft’s Knowledge Base website

at: http://support.microsoft.com/kb/888137.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are not

experiencing any problems with your system. Updated BIOS les are located on

our web site 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 le to your computer.

Also, check the current BIOS revision and make sure that it is newer than your

BIOS before downloading. You can choose from the zip le and the .exe le. If

you choose the zip BIOS le, please unzip the BIOS le onto a bootable device or

a USB pen. Run the batch le using the format ash.bat lename.rom from your

bootable device or USB pen to ash the BIOS. Then, your system will automati-

cally 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, bootup 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.

3-3

X7DCL-3/X7DCL-i User's Manual

(Warning: Do not shut down or reset the system while updating BIOS to

prevent possible system boot failure!)

Question: What's on the CD that came with my motherboard?

Answer: The supplied compact disc has quite a few drivers and programs that will

greatly enhance your system. We recommend that you review the CD and install

the applications you need. Applications on the CD include chipset drivers for the

Windows OS, and security and audio drivers.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required

before any warranty service will be rendered. You can obtain ser vice by calling

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DCL-3/X7DCL-i.

Phoenix ROM BIOS is stored in a ash chip and can be easily upgraded using a

oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been added

or deleted and might not yet be recorded in this manual. Please refer to the Manual

Download area of the Super Micro web site <http://www.supermicro.com> for any

changes to the BIOS that may not be reected in this manual.

System BIOS

BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and PS/2®

compatible computers. Phoenix BIOS stores the system parameters, types of disk

drives, video displays, etc. in the CMOS. CMOS memory requires very little electrical

power. When the computer is turned off, a backup battery provides power to the

CMOS Logic, enabling it to retain system parameters. Each time the computer is

powered on, the computer is congured with the values stored in the CMOS Logic

by the system BIOS, which gains control at boot up.

HowToChangetheCongurationData

The CMOS information that determines the system parameters may be changed by

entering the BIOS Setup utility. This Setup utility can be accessed by pressing the

<Delete> key at the appropriate time during system boot. (See below.)

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As

the memory is being tested, press the <Delete> key to enter the main menu of the

BIOS Setup utility. From the main menu, you can access the other setup screens,

such as the Security and Power menus. Beginning with Section 4-3, detailed de-

scriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating BIOS

to prevent possible boot failure.

This option allows the user to select the CPU Overheat Alarm setting which de-

termines when the CPU OH alarm will be activated to provide warning of possible

CPU overheat. Refer to the the next item, CPU Temperature for more information

regarding PECI, DTS and other thermal features of this motherboard.

Warning: Any temperature that exceeds the CPU threshold temperature

predened by the CPU manufacturer may result in CPU overheat or system

instability. When the CPU temperature reaches this predened threshold,

the CPU and system cooling fans will run at full speed.

The options are:

The Default Alarm Setting: Select this setting if you want the CPU overheat alarm

(including the LED and the buzzer) to be triggered when the CPU temperature

reaches about +5 PECI counts above the threshold temperature as predened by

the CPU manufacturer to give the CPU and system fans additional time needed

for CPU and system cooling.

The Early Alarm Setting: Select this setting if you want the CPU overheat alarm

(including the LED and the buzzer) to be triggered as soon as the CPU temperature

reaches the CPU overheat threshold as predened by the CPU manufacturer.

CPU1 Temperature/CPU2 Temperature

The CPU Temperature feature will display the CPU temperature status as detected

by the BIOS:

Low – This level is considered as the ‘normal’ operating state. The CPU temperature

is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will

run normally as congured in the BIOS (Fan Speed Control).

User intervention: No action required.

Medium – The processor is running warmer. This is a ‘precautionary’ level and gen-

erally means that there may be factors contributing to this condition, but the CPU is

still within its normal operating state and below the CPU ‘Temperature Tolerance’.

The motherboard fans and CPU will run normally as congured in the BIOS. The

fans may adjust to a faster speed depending on the Fan Speed Control settings.

User intervention: No action is required. However, consider checking the CPU

fans and the chassis ventilation for blockage.

4-17

X7DCL-3/X7DCL-i User's Manual

High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-

perature Tolerance’ has been reached (or has been exceeded) and may activate

an overheat alarm:

The Default Alarm – the Overheat LED and system buzzer will activate if the High

condition continues for some time after it is reached. The CPU fan will run at full

speed to bring the CPU temperature down. If the CPU temperature still increases

even with the CPU fan running at full speed, the system buzzer will activate and

the Overheat LED will turn on.

The Early Alarm – the Overheat LED and system buzzer will be activated exactly

when the High level is reached. The CPU fan will run at full speed to bring the

CPU temperature down.

Note: In both the alarms above, please take immediate action as shown below.

See CPU Overheat Alarm to modify the above alarm settings.

User intervention: If the system buzzer and Overheat LED has activated, take

action immediately by checking the system fans, chassis ventilation and room

temperature to correct any problems. Note: the system may shut down if it con-

tinues for a long period to prevent damage to the CPU.

Notes: The CPU thermal technology that reports absolute temperatures

(Celsius/Fahrenheit) has been upgraded to a more advanced feature by

Intel in its newer processors. The basic concept is each CPU is embedded

by unique temperature information that the motherboard can read. This

‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned

at the factory and is the baseline on which the motherboard takes action

during different CPU temperature conditions (i.e., by increasing CPU Fan

speed, triggering the Overheat Alarm, etc). Since CPUs can have different

‘Temperature Tolerances’, the installed CPU can now send information to

the motherboard what its ‘Temperature Tolerance’ is, and not the other way

around. This results in better CPU thermal management.

Supermicro has leveraged this feature by assigning a temperature status to certain

thermal conditions in the processor (Low, Medium and High). This makes it easier

for the user to understand the CPU’s temperature status, rather than by just simply

seeing a temperature reading (i.e., 25oC).

The information provided above is for your reference only. For more information on

thermal management, please refer to Intel’s Web site at www.Intel.com.

System Temperature

This feature displays the system's absolute temperature reading (i.e., 34oC).

CPU on-die temperature increases, the fan speed will also increase, and vise versa.

If the option is set to 3-pin fan, the fan speed is controlled by voltage. If the option

is set to 4-pin, the fan speed will be controlled by Pulse Width Modulation (PWM).

Select 3-pin if your chassis came with 3-pin fan headers. Select 4-pin if your chas-

sis came with 4-pin fan headers. Select Workstation if your system is used as a

Workstation. Select Server if your system is used as a Server. Select Disable to

disable the fan speed control function to allow the onboard fans to run at full speed

(12V) at all times. The Options are: 1. Disable (Full Speed), 2. 3-pin (Server), 3.

3-pin (Workstation), 4. 4-pin (Server) and 5. 4-pin (Workstation).

Voltage Monitoring

The following items will be monitored and displayed:

Vcore A, Vcore B, -12V, P1V5, +3.3V, 5Vsb, 5VDD, P_VTT, Vbat

Note: In the Windows OS environment, the Supero Doctor III settings take prece-

dence over the BIOS settings. When rst installed, Supero Doctor III adopts the

temperature threshold settings previously set in the BIOS. Any subsequent changes

to these thresholds must be made within Supero Doctor, since the SD III settings

override the BIOS settings. For the Windows OS to adopt the BIOS temperature

threshold settings, please change the SDIII settings to be the same as those set

in the BIOS.

The Supero Doctor III program is a Web-based management tool that supports

remote management capability. It includes Remote and Local Management tools.

The local management is called the SD III Client. The Supero Doctor III program

included on the CDROM that came with your motherboard allows you to monitor

the environment and operations of your system. Supero Doctor III displays crucial

system information such as CPU temperatures, system voltages and fan status.

See the Figure below for a display of the Supero Doctor III interface.

Note 1: Both default username and password are ADMIN.

Note 2: In the Windows OS environment, the Supero Doctor III settings take

precedence over the BIOS settings. When rst installed, Supero Doctor III adopts

the temperature threshold settings previously set in the BIOS. Any subsequent

changes to these thresholds must be made within Supero Doctor, since the SD

III settings override the BIOS settings. For the Windows OS to adopt the BIOS

temperature threshold settings, please change the SDIII settings to be the same

as those set in the BIOS.
