About This Manual
This manual is written for system integrators, PC technicians and knowledgeable
PC users. It provides information for the installation and use of the
X6QT8/X6QTE+ motherboard. The X6QT8/X6QTE+ supports single, dual
or quad 64-bit Intel®Xeon processor MP, 7000 Series and 7100 Series processors
at a front side bus speed of 800 or 677 MHz. Based upon the 64-bit Intel Xeon
MP/7000 Series/7100 Series processors, the X6QT8/X6QTE+ supports
the dual system bus architecture, and allows for symmetric multiprocessing across
two shared system bus interfaces, providing performance enhancement with
increased bus speeds and bandwidth. This motherboard is especially designed
for the 4-way server platform, and can be used in front-end, back-end, general-
purpose, communication and storage market segments. Please refer to our web
site (http://www.supermicro.com/products/motherboard/) for updates on supported
processors. This product is intended to be professionally installed.

Important Notes to the User
1. All images and graphics shown in this manual were based upon the latest
PCB revision available at the time of publishing of this manual. The motherboard
you've received may or may not look exactly the same as the graphics shown in
this manual.
2. The X6QTE+ does not contain onboard SCSI components and dual PXH Con-
trollers. It has only one PCI-Exp. slot (Slot 6: PCI-Exp. x16).
3. When one CPU is used, install it in CPU Socket #1. When two CPUs are
used, install them in Socket #1 and Socket #2. If three CPUs are used, install
them in Sockets #1, #2 and #3.
4. To optimize memory performance, please refer to Memory Installation on Page
2-6 in Chapter 2.

•1.Jumpers not indicated are for testing only.
•2. " " indicates the location of "Pin 1".
•3. SCSI, PCI Slots #1-#5, ZCR and PXHs are available on the X6QT8 only.
•4. Both IDE#1 and IDE#2 support compact flash cards. When a compact flash
card is installed, be sure to connect a power cable to its PWR header (JWF1
for IDE1, JWF2 for IDE2).
•5. UXMB1-UXMB4: These are extended memory bridge chips that came with the
chipset.
•6. CPLD stands for Complex Programmable Logic Devices.
•7. For the SCSI ZCR card to work properly, please install it in the green slot.
•8. If one CPU is used, install it in CPU Socket#1; if two CPUs are used, install
them in Sockets #1 & #2. If three, install them in Sockets #1, #2 and #3.
•9. For best memory performance, install DIMM modules in the following slots
first: DIMMs A1& B1, DIMMs A3 & B3, DIMMs A5 & B5, DIMMs A7 & B7. Also

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 configuration 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 configured 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

1-3 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 define 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-defined
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 define an overheat temperature.

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: 880C, *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 Configuration and Power Interface) specification defines a
flexible 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 configuration 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.
