1.5 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.5 V DDR3 800 MHz, DDR3 1066 MHz, and DDR3 1333 (OC) 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.
• 8 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.
Table 3 lists the supported DIMM configurations.

Product Description
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 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.

G43 Express Chipset
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 Intel
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
19
Intel Desktop Board DG43RK Technical Product Specification
• 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.

1.6.1.6 Advanced Digital Display (ADD2/MEC/ADD2+) Card
Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
400 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC/ADD2+
card is detected, the Intel GMA X4500HD 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/ADD2+ card. An ADD2/MEC/ADD2+ 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 with DVI analog output only. ADD2/MEC/ADD2+ cards can be
designed to support the following configurations:
• Low Voltage Differential Signaling (LVDS)
• Single device operating in dual channel mode
• HDTV output
1.6.1.7 PCI Express x16 Graphics
The GMCH also supports add in discrete graphics card via the PCI Express 2.0 graphics
connector.

Product Description
1.6.3 ATA Support
The board provides five ATA interface connectors:
• One PATA connector that supports two devices
• Four SATA connectors that support one device per connector
1.6.3.1 PATA Interface
The discrete PATA controller has one bus-mastering PATA interface that is accessible
through a 44-pin connector. The PATA 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/s.
• Ultra DMA: DMA protocol on ATA bus supporting host and target throttling and
transfer rates of up to 33 MB/s.
• ATA-66: DMA protocol on ATA bus supporting host and target throttling and
transfer rates of up to 66 MB/s. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
• ATA-100: DMA protocol on ATA bus allows host and target throttling. The
controller’s ATA-100 logic can achieve read transfer rates up to 100 MB/s and write
transfer rates up to 88 MB/s.
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce
reflections, noise, and inductive coupling.
The PATA interface also supports ATAPI devices (such as optical drives) and ATA
devices using the transfer modes.
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.

Intel Desktop Board DG43RK Technical Product Specification
1.6.3.2 SATA Interfaces
The Intel ICH10 SATA controller offers four independent SATA ports with a theoretical
maximum transfer rate of 3.0 Gb/s on each port. One device can be installed on each
port for a maximum of four SATA devices. A point-to-point interface is used for host
to device connections, unlike PATA which supports a master/slave configuration and
two devices on each channel.
For compatibility, the underlying SATA functionality is transparent to the operating
system. The SATA controller supports IDE and AHCI (Microsoft Windows Vista only)
configuration and can operate in both legacy and native modes. In legacy mode,
standard ATA I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode,
standard Conventional PCI bus resource steering is used. Native mode is the
preferred mode for configurations using the Windows* XP and Windows Vista
operating systems.

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.
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.
