• DDR2 800 MHz 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.

Product Description
1.5.1 Memory Configurations
The Intel 82Q45 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 4 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.

DMI interconnect. The component also provides integrated graphics capabilities
supporting 3D, 2D, and display capabilities. The ICH10DO is a centralized controller
for 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 Q45 Express chipset http://www.intel.com/products/desktop/chipsets/index.htm
Resources used by the chipset Chapter 2
1.6.1 Intel Q45 Graphics Subsystem
The Intel Q45 Express chipset contains the Intel Graphics Media Accelerator 4500
(Intel GMA 4500) graphics controller.
1.6.1.1 Intel® Graphics Media Accelerator 4500 Graphics
Controller
The Intel GMA 4500 graphics controller features the following:
• High quality texture engine
⎯ DirectX10* and OpenGL* 2.0 compliant
⎯ Shader Model 4.0
• 3D Graphics Rendering enhancements
⎯ 1.6 dual texture GigaPixel/sec max fill rate
⎯ 16-bit and 32-bit color
⎯ Vertex cache
• Video
⎯ Hi-Definition playback (partial hardware acceleration for MPEG-2, full hardware
acceleration for VC1 and AVC)
⎯ Dynamic Video Memory Technology (DVMT) 5.0 uses system memory
depending on the OS and the amount of memory installed
19
Intel Desktop Board DQ45EK Technical Product Specification
• Display
⎯ Supports digital and analog displays up to 2048 x 1536 at 75 Hz refresh
(QXGA); also supports 1920 x 1080 resolution for full High Definition video
playback quality
⎯ Dual independent display support
1.6.1.2 Dynamic Video Memory Technology (DVMT 5.0)
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. The amount of system memory
allocated to DVMT varies depending on the amount of total system memory installed
as well as the operating system being used. For Windows Vista, a minimum of 128 MB
can be allocated to DVMT and a maximum of over 2 GB can be allocated to DVMT with
the correct amount of 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 Visual Interface (DVI)
The DVI-I port supports both digital and analog DVI displays. The maximum
supported resolution is 2048 x 1536 at 75 Hz refresh (QXGA). The DVI port is
compliant with the DVI 1.0 specification.
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 2048 x 1536 at 75 Hz refresh (QXGA). The DVI-D port is compliant with the DVI
1.0 specification.

connector. The board also provides one red-colored external Serial ATA (eSATA)
connector on the back panel.
1.6.3.1 Serial ATA Support
The board’s Serial ATA controller offers five 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 five Serial ATA devices. A point-to-point 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.

1.6.3.2 Serial ATA RAID
The 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
1.6.3.3 Intel® Rapid Recover Technology
The board incorporates the Intel® Rapid Recover Technology (Intel® RRT). Intel®
Rapid Recover Technology is a feature of Intel® Matrix Storage Manager. It uses RAID
1 (mirroring) functionality to copy data from a designated master drive to a
designated recovery drive. The master drive data can be copied to the recovery drive
either continuously or on request.
When using the continuous update policy, changes made to the data on the master
drive while the recovery drive is disconnected or offline are automatically copied to the
recovery drive when it is reconnected. When using the on request update policy, the
22
Product Description
master drive data can be restored to a previous state by copying the data on the
recovery drive back to the master drive.
1.7 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. If the battery is removed or exhausted, the Intel TPM
data will be deleted in accordance to Trusted Computing Group guidelines. Please read
the user guide and back-up Intel TPM keys and data before removing the coin cell
battery.
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 11 shows the location of the battery.
