X6QT8/X6QTE+ User's Manual
1-2 Chipset Overview
The E8501 Chipset
Built upon the functionality and the capability of the E8501 chipset, the X6QT8/
X6QTE+ motherboard provides the performance and feature set required for 4-Way
servers with confi guration options optimized for communications, storage, computa-
tion or database applications. The Intel E8501 chipset is built around the E8501
chipset North Bridge (NB), and the Intel E8501 chipset external Bridge (XMB).
The E8501 chipset North Bridge (NB) provides the interconnection between 64-bit
Intel Xeon MP/7000 Series/7100 Series Processors, XMB (via four independent
Memory Interfaces), I/O components via PCI-Express Links and ICH5R. It sup-
ports up to four 64-bit Xeon processor MP/7000 Series/7100 Series processors at
a Front Side Bus of 667MHz or 800MHz. It offers ECC protection on data signals,
parity protection on address signals, and supports Return Data by Enhanced Defer
to allow for extraordinary completion.
Independent Memory Interface
Memory support features include the following:
• Four Independent Memory Interface (IMI) ports, each with up to 5.33 GB
bandwidth (read) and 2.67 GB bandwidth (write) simultaneously at 166.7 MHz,
or with up to 6.4 GB bandwidth (read) and 3.2 GB bandwidth (write) simulta-
neously at 200 MHz
• 40-bit addressing support provides one terabyte addressing capability
• Memory technology independent
I/O Interfaces
The E8501 chipset relies on PCI Express to provide the interconnection between
the North Bridge and the I/O subsystem. The I/O subsystem is based on three x4
PCI Express links, two x8 PCI Express links, and one HI1.5 link.
• Three x4 and two x8 (each can be confi gured as two x4,) making a total of
seven x4 links
• Dual PXH Controllers with 2 PCI-X buses per controller. (Each bus supports
up to 133 MHz.) (*Note: for the X6QT8 only.)
HI 1.5
• 8-bit wide, 4x data transfer, 66 MHz base clock with 266 MB/s bandwidth
• Legacy I/O interconnection to the ICH5R
Transaction Processing Capabilities
• 64 transactions processed concurrently
• 128-entry Common Data Cache (CDC) for write combining and write buffering
1-12
Chapter 1: Introduction
1-3 Special Features
Recovery from AC Power Loss
The feature allows the user to set the power state after a power outage. You can
select Power-Off for the system power to remain off after a power loss. Select
Power-On for the system power to be turned on after a power loss. Select Last
State to allow the system to resume its last state before the power loss. The default
setting is Last State.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER X6QT8
/X6QTE+. It has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for the CPU Cores, +3.3V, +5V, +12V,
-12V and +3.3V Standby
An onboard voltage monitor will scan these voltages 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 (via Supero Doctor III) to defi ne the sen-
sitivity of the voltage monitor.
Fan Status Monitor with Fan Speed 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.
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-defi ned
threshold. The overheat circuitry runs independently from the CPU. It can continue
to monitor for overheat conditions even when the CPU is in sleep mode. Once it
detects that the CPU temperature is too high, it will automatically turn on the ther-
mal control fan to prevent any overheat damage to the CPU. The onboard chassis
thermal circuitry can monitor the overall system temperature and alert users when
the chassis temperature is too high.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature.
1-13
X6QT8/X6QTE+ User's Manual
Thermal Management/CPU VRM Overheat
When the CPU reaches 700 C and above (Overheat), the CPU will go into throttling
state. CPU Voltage will decrease to reduce CPU power consumption. When the
CPU temperature reaches 780 C (*Default) and above, the Overheat LED and the
Alarm Buzzer will be turned on in addition to the slowing down of the CPU. Once
the CPU temperature returns to normal, the CPU voltage will return to normal as
well, allowing the CPU to run at maximum speed.
VRM Protection
When the CPU VRM temperature reaches the threshold preset by the user in the
BIOS, the system will go into TM (Thermal Management) mode. The CPU will slow
down and the VRM current will drop to prevent the VRM from overheating. (The
settings are: 88
0
C, *980C, 1080C.) (*Default)
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to 20A current.
This will allow the regulator to run cooler and thus make the system more stable.
1-5 ACPI Features
The ACPI (Advanced Confi guration and Power Interface) specifi cation defi nes a
fl exible and abstract hardware interface that provides a standard way to integrate
power management features throughout a PC system, including its hardware, op-
erating 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 confi 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
Server 2003.
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.
1-14
Chapter 1: Introduction
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 Button Instant-Off
feature under the Advanced Chipset Section in the BIOS Setup.
External Modem Ring-On (WOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can only
be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, updates and asset-
tracking can occur after hours and on weekends so that daily LAN traffi c is kept
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 X6QT8/X6QTE+ can only accommodate ATX 24-pin and 8-pin power supplies.
Although most power supplies generally meet the specifi cations required by the
CPU, some are inadequate. Your power supply must have one 24-pin and two
12V 8-pin connectors and should supply at least 650W of power; an even higher
wattage power supply is recommended for high-load confi gurations. Also, your
power must supply 1.5A for the Ethernet ports.
*Note: Two additional 12V 8-pin power connectors (JPW2/JPW3) are required for
Intel Xeon MP CPUs. Failure to provide this extra power to the CPU may make it
unstable within a few minutes of operation. See Section 2-6 for details on power
connectors.
1-15
X6QT8/X6QTE+ User's Manual
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 2.01 or above. It must also be SSI compliant (-refer to
the web site at http://www.ssiforum.org/ for details). Additionally, in areas where
noisy power transmission is present, you may choose to install a line fi 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 fl 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 genera-
tor, 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 fl 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). 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 supports one PC-compatible printer port (SPP), Bidirectional Printer
Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Confi 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
Electric-Static-Discharge (ESD) can damage electronic com ponents. To
prevent damage to your system board, it is important to handle it very
!
carefully. The following measures are generally suffi 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 specifi ed by the manu-
facturer. Do not install the onboard battery upside down to avoid possible explo-
sion.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.
2-1
X6QT8/X6QTE+ User's Manual
2-2 Processor and Heatsink Installation
When handling the processor package, avoid placing direct pressure
on the label area of the fan. Also, do not place the motherboard on a
conductive surface which can damage the BIOS battery and prevent
!
system bootup.
IMPORTANT: Always connect the power cord last and always remove it before add-
ing, removing or changing any hardware components. Make sure that you install
the processor into the CPU socket before you install the CPU heat sink.
*Note: For proper system cooling, please use the heatsink provided by
Supermicro.
CPU Installation
1. Lift the lever on the CPU socket--lift
the lever completely as shown on the
picture on the right; otherwise, you will
damage the CPU socket when power is
applied. (Install CPU1 fi rst.)
2. Insert the CPU in the socket, making
sure that pin 1 of the CPU aligns with pin
1 of the socket (both corners are marked
with a triangle). When using only one
CPU, install it into CPU socket #1 (CPU
sockets will be automatically disabled if
not in use).
3. Press the lever down until you hear a
click, so you can be sure that the CPU is
securely installed in the CPU socket.
(*Note: CPUs shown in the pictures are for display only.

Heatsink Installation
IMPORTANT: Due to the weight of the Passive Heatsink (about 1KG), you
need to have Heatsink Mounting plate installed on the chassis to prevent
!
damage to the CPU and the motherboard)
Chapter 2: Installation
1. Do not apply any thermal compound to
the heatsink or the CPU die-the required
amount has already been applied.
2. Place the heatsink on top of the CPU so
that the four mounting holes are aligned with
those on the retention mechanism.
3. Screw in two diagonal screws (ie the #1
and the #2 screws) until just snug (-do not
fully tighten the screws to avoid possible
damage to the CPU.)
4. Finish the installation by fully tightening
all four screws.

1. Insert the desired number of DIMMs into the memory slots, starting with the fi rst
DIMM of the fi rst bank. Each UXMB chip is independent from each other,
so memory modules can be installed on the fi rst bank of a UXMB Controller.
For best memory performance, 8 memory modules minimal are required (-2
modules for each UXMB chip. See the Memory Table below.)
