Desktop Board DG33TL
Supported processors http://www.intel.com/go/findcpu
Chipset information http://www.intel.com/products/desktop/chipsets/index.htm
BIOS and driver updates http://downloadcenter.intel.com
The board is designed to support the following processors:
• Intel Core 2 Quad processor in an LGA775 socket with a 1066 MHz system bus
• Intel Core 2 Duo processor in an LGA775 socket with a 1333 or 1066 or 800 MHz
system bus
•Intel Pentium Dual-Core processor in an LGA775 socket with an 800 MHz
system bus
•Intel Celeron processor in an LGA775 socket with an 800 MHz system bus
Other processors may be supported in the future. This board is designed to support
processors with a maximum wattage of 105 W. The processors listed above are only
supported when falling within the wattage requirements of the DG33TL board. See
the Intel web site listed below for the most up-to-date list of supported processors.
The board has four DIMM sockets and support the following memory features:
• 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
•8 GB maximum total system memory using DDR2 800 or DDR2 667 DIMMs; refer
to Section
2.1.1 on page 39 for information on the total amount of addressable
memory.
• Minimum total system memory: 512 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 800 or DDR2 667 MHz SDRAM DIMMs
• DDR2 667 DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
• DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the DIMMs may not function under the
determined frequency.
The Intel 82G33 GMCH supports the following types of memory organization:
•Dual channel (Interleaved) mode. This mode offers the highest throughput for
real world applications. Dual channel mode is enabled when the installed memory
capacities of both DIMM channels are equal. Technology and device width can vary
from one channel to the other but the installed memory capacity for each channel
must be equal. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
•Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
•Flex mode. This mode provides the most flexible performance characteristics.
The bottommost DRAM memory (the memory that is lowest within the system
memory map) is mapped to dual channel operation; the topmost DRAM memory
(the memory that is nearest to the 8 GB address space limit), if any, is mapped to
single channel operation. Flex mode results in multiple zones of dual and single
channel operation across the whole of DRAM memory. To use flex mode, it is
necessary to populate both channels.
Figure 3 illustrates the memory channel and DIMM configuration.
NOTE
The DIMM 0 sockets of both channels are blue. The DIMM 1 sockets of both channels
are black.
Figure 3. Memory Channel and DIMM Configuration
INTEGRATOR’S NOTE
#
Regardless of the memory configuration used (dual channel, single channel, or flex
mode), DIMM 0 of Channel A must always be populated. This is a requirement of the
®
Intel
Management Engine.

the board’s I/O paths.
The chipset supports the following features:
• Onboard Graphics
• Dynamic Video Memory Technology
• USB
• Serial ATA
For information about Refer to
The Intel G33 Express chipset http://www.intel.com/products/desktop/chipsets/index.htm
Resources used by the chipset Chapter 2
1.6.1 Intel G33 Graphics Subsystem
The Intel G33 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel Graphics Media Accelerator 3100 (Intel GMA 3100) graphics
controller (contained within the 82G33 GMCH) is used, or a PCI Express x16 add-in
card can be used. When a PCI Express x16 add-in card is installed, the Intel GMA
3100 graphics controller is disabled.
1.6.1.1 Intel® Graphics Media Accelerator 3100 Graphics
Controller
The Intel GMA 3100 graphics controller features the following:
• 400 MHz core frequency
• High quality texture engine
⎯ DX9.0c* and OpenGL* 1.4 compliant
⎯ Hardware Pixel Shader 2.0
⎯ Vertex Shader Model 2.0
• 3D Graphics Rendering enhancements
⎯ 1.6 dual texture GigaPixel/sec max fill rate
⎯ 16-bit and 32-bit color
⎯ Vertex cache
• Video
⎯ Software DVD at 30 fps full screen
⎯ DVMT support up to 256 MB

⎯ Supports analog displays up to 2048 x 1536 at 75 Hz refresh (QXGA)
⎯ Dual independent display support
⎯ DDC2B compliant interface with Advanced Digital Display 2 card or Media
Expansion Card (ADD2/MEC), support for TV-out/TV-in and DVI digital display
connections
1.6.1.2 Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization. DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance. Up to 256 MB of system memory can be
allocated to DVMT on systems that have 512 MB or more of total system memory
installed. DVMT returns system memory back to the operating system when the
additional system memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications. An example of this
would be when using VGA graphics under DOS. Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.
NOTE
The use of DVMT requires operating system driver support.
1.6.1.3 Configuration Modes
The video modes supported by this board are based on the Extended Display
Identification Data (EDID) modes of the monitor to which the system is connected.
Standard monitors are assumed.
1.6.1.4 Digital Video Interface (DVI)
The DVI port supports only DVI-D displays. If a DVI-I display is connected, only the
digital signal will be displayed. The maximum supported resolution is 1600 x 1200 at
60 Hz. The DVI port is compliant with the DVI 1.0 specification.
Depending on the type of add-in card installed in the PCI Express x16 connector, the
DVI port will behave as described in
Table 4. DVI Port Status Conditions
PCI Express x16 connector status DVI port status
No add-in card installed Enabled
Non-video PCI Express x1 add-in card installed Enabled

Product Description
1.6.1.5 Advanced Digital Display (ADD2/MEC) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
225 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC card is
detected, the Intel GMA 3100 graphics controller is enabled and the PCI Express x16
connector is configured for SDVO mode. SDVO mode enables the SDVO ports to be
accessed by the ADD2/MEC card. An ADD2/MEC card can either be configured to
support simultaneous display or can be configured to support dual independent display
as an extended desktop configuration with different color depths and resolutions.
ADD2/MEC cards can be designed to support the following configurations:
• Low Voltage Differential Signaling (LVDS)
• Single device operating in dual channel mode
• HDTV output
• HDMI support (when used with the HD Audio Link)
1.6.2Intel® Viiv™ Processor Technology
This Intel desktop board supports Intel® Viiv™ processor technology. To be eligible for
the Intel Viiv processor technology brand, a system must meet certain hardware and
software requirements. To get the list of requirements for Intel Viiv processor
technology branding as well as all the features supported by Intel Viiv processor
technology, refer to:
http://www.intel.com/products/viiv/index.htm
1.6.3 USB
The board supports up to 12 USB 2.0 ports, supports UHCI and EHCI, and uses UHCIand EHCI-compatible drivers.
The ICH9R provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Six ports are routed to three separate front panel USB headers
For information about Refer to
The location of the USB connectors on the back panel Figure 9, page 43
The location of the front panel USB headers Figure 10, page 44
The board provides five Serial ATA (SATA) connectors, which support one device per
connector. The board also provides one red-colored external Serial ATA (eSATA)
connector.
1.6.4.1 Serial ATA Support
The DG33TL Desktop Board’s Serial ATA controller offers six independent Serial ATA
ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device
can be installed on each port for a maximum of six Serial ATA devices. A point-topoint interface is used for host to device connections, unlike Parallel ATA IDE which
supports a master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
and 15). In Native mode, standard PCI Conventional bus resource steering is used.
Native mode is the preferred mode for configurations using the Windows* XP and
Windows Vista operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.
For more information, see:
For information about Refer to
The location of the Serial ATA connectors Figure 10, page 44
http://www.serialata.org/.
1.6.4.2 Serial ATA RAID
The DG33TL Desktop Board supports the following RAID (Redundant Array of
Independent Drives) levels:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and mirroring
• RAID 5 - distributed parity
22
Product Description
1.7 Parallel IDE Controller
The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The
Parallel ATA IDE interface supports the following modes:
• Programmed I/O (PIO): processor controls data transfer.
• 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to
16 MB/sec.
•Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
•ATA-66: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
•ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce
reflections, noise, and inductive coupling.
The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives)
and ATA devices. The BIOS supports Logical Block Addressing (LBA) and Extended
Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate
and translation mode to the BIOS.
For information about Refer to
The location of the Parallel ATA IDE connector Figure 10, page 44
1.8 Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied.
NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded
into CMOS RAM at power-on.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one.
Figure 1 on page 12 shows the location of the battery.
The I/O controller provides the following features:
• Consumer Infrared (CIR) headers
• One serial port header
• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• PS/2-style mouse and keyboard interfaces
• Intelligent power management, including a programmable wake-up event interface
• PCI power management support
The BIOS Setup program provides configuration options for the I/O controller.
1.9.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer
Infrared usage models. Microsoft Windows Vista* is the supported operating system
The CIR feature is made up of two separate pieces: the receiving header, and the
emitter header. The receiving header consists of a filtered translated infrared input
compliant with Microsoft CIR specifications, and also a “learning” infrared input. This
learning input is simply a high pass input which the computer can use to “learn” to
speak the infrared communication language of other user remotes. The emitter
header consists of two output ports which the PC can use to emulate “learned”
infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to plug into Intel
Desktop Boards for this feature to work.
1.9.2 Serial Port
The board has one serial port header located on the component side of the board. The
serial port supports data transfers at speeds up to 115.2 kbits/sec with BIOS support.
