• 1.8 V DDR2 SDRAM DIMMs with gold plated contacts, with the option to raise the
voltage to 1.92 V to support higher performance DDR2 SDRAM DIMMs
• Dual channel interleaved mode support
• 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 MHz or DDR2 667 MHz
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 MHz or DDR2 667 MHz SDRAM DIMMs
⎯ DDR2 667 MHz DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
⎯ 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 82Q43 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.

INTEGRATOR’S NOTE

Regardless of the memory configuration used (dual channel, single channel, or flex
mode), Channel A must always be populated. This is a requirement of the Intel
Management Engine.

Q43 Express Chipset
1.6.1 Intel Q43 Graphics Subsystem
The Intel Q43 Express chipset contains two graphics options. Either the Intel Graphics
Media Accelerator 4500 (Intel GMA 4500) graphics controller (contained within the
82Q43 GMCH) is used or a PCI Express x1 add-in graphics card can be used.
1.6.1.1 Intel
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 based on
the operating system and the amount of memory installed
®
Graphics Media Accelerator 4500 Graphics
19
Intel Desktop Board DQ43AP 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 (VGA and DVI-D)
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.

Product Description
1.6.1.4 Digital Visual Interface (DVI)
The DVI-D port supports 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.
1.6.2 USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers.
The ICH10D provides the USB controller for all ports. The port arrangement is as
follows:
• Four ports are implemented with stacked back panel connectors
• Four ports are routed to two 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
1.6.3 Serial ATA Interfaces
The board provides two Serial ATA (SATA) connectors, which support one device per
connector. The board also provides one red external Serial ATA (eSATA) connector.
1.6.3.1 Serial ATA Support
The board’s Serial ATA controller offers three 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 three Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA 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.

Intel Desktop Board DQ43AP Technical Product Specification
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. Refer to the
TPM Quick Reference and back-up Intel TPM keys and data before removing the coincell 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.
