1.5 System Memory
The board has four DIMM sockets and supports the following memory features:
•1.8 V DDR2 800 MHz and DDR2 667 MHz SDRAM DIMMs
•Two independent memory channels with interleaved mode support
•Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
•16 GB maximum total system memory (with 2 Gb memory technology). Refer to
Section 2.1.1 on page 41 for information on the total amount of addressable
memory.
•Minimum total system memory: 512 MB
•Non-ECC DIMMs
•Serial Presence Detect
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.

1.5.1 Memory Configurations
The Intel 82G43 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 16 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.
Figure 3. Memory Channel and DIMM Configuration
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.

1.6 Intel®G43 Express Chipset
The Intel G43 Express chipset consists of the following devices:
•Intel 82G43 Graphics and Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
•Intel 82801JIB I/O Controller Hub (ICH10)
The GMCH component provides interfaces to the CPU, memory, and the DMI
interconnect. The component also provides integrated graphics capabilities supporting
3D, 2D, and display capabilities. ICH10 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 G43 Express chipset http://www.intel.com/products/desktop/chipsets/index.htm
Resources used by the chipset Chapter 2
1.6.1 Intel G43 Graphics Subsystem
The Intel G43 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel GMA X4500 graphics controller (contained within the 82G43
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 X4500 graphics controller is disabled.
1.6.1.1 Intel®Graphics Media Accelerator X4500 Graphics
Controller
The Intel GMA X4500 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/s 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

Intel Desktop Board DG43GT Technical Product Specification
20
•Display
⎯Supports digital and analog displays up to 1920 x 1200 at 60 Hz refresh
(WUXGA) and 2560 x 1600 at 60 Hz refresh (WQXGA) respectively; also
supports 1920 x 1080 resolution for full High Definition video playback quality
⎯Dual independent display support (HDMI and DVI-I)
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.
