Intel Desktop Board D865GSA Technical Product Specification
1.4 System Memory
The board has two DIMM sockets and supports the following memory features:
• 2.6 V (only) 184-pin DDR 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.
• 2 GB maximum total system memory.
• Minimum total system memory: 64 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR400, DDR333, and DDR266 SDRAM DIMMs
Table 3 lists the supported system bus frequency and memory speed combinations.
Table 3. Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM… The processor's system bus frequency must be…
DDR400 800 MHz
DDR333 (Note) 800 or 533 MHz
DDR266 800, 533, or 400 MHz
Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz.
This minimizes system latencies to optimize system throughput.
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 enables 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.

1.4.1 Memory Configurations
The Intel 82865G GMCH component provides two features for enhancing memory
throughput:
• Dual Channel memory interface. The board has two memory channels, each with a
single DIMM socket, as shown in Figure 3
• Dynamic Addressing Mode. Dynamic mode minimizes overhead by reducing
memory accesses
Table 5 summarizes the characteristics of Dual and Single Channel configurations with
and without the use of Dynamic Mode.

Product Description
1.5.1.3 Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through Direct AGP, and
highly efficient memory utilization. DVMT ensures the most efficient use of available
system memory for maximum 2-D/3-D graphics performance. Up to 64 MB of system
memory can be allocated to DVMT on systems that have 256 MB or more of total
system memory installed. Up to 32 MB can be allocated to DVMT on systems that have
128 MB but less than 256 MB of total installed system memory. Up to 8 MB can be
allocated to DVMT when less than 128 MB of system memory is 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.
1.5.1.4 Zone Rendering Technology (ZRT)
The Intel Extreme Graphics 2 Controller supports Zone Rendering Technology (ZRT).
ZRT is a process by which the screen is divided into several zones. Each zone is
completely cached and rendered on chip before being written to the frame buffer. The
benefits of ZRT include the following:
• Increased memory efficiency via better localization of data
• Increased on-chip processing speed due to decreased wait time for data
• Increased effective pixel fill rates
• Increased headroom for larger resolution and color depth
• Reduced power as a result of decreased memory bandwidth
• Reduction in depth and color bandwidth associated with conventional rendering
1.5.1.5 Rapid Pixel and Text Rendering (RPTR)
The Rapid Pixel and Text Rendering Engine (RPTR) architecture utilizes special pipelines
that allow 2D and 3D operations to overlap. By providing 8X compression, the RPTR
engine reduces the memory bandwidth required to read texture memory, and reduces
the amount of memory required for texture storage.
A dedicated, non-blocking, multi-tier cache is provided for textures, colors, Z and
vertex rendering. With single-pass, quad texture support, the drivers can submit up to
four textures that pass to the graphics engine concurrently. The graphics core can
switch between 2D and 3D operations without having to complete all operations of the
same mode, which minimizes the overhead time required in switching between modes.
27
Intel Desktop Board D865GSA Technical Product Specification
A 2D Block Level Transfer (BLT) in the RPTR engine is extended to 256-bit, which
supports fast blitter fill rate. This enables the blitter sequence of the same addresses
to access the cache and offloads the memory bandwidth required to support blitter fill
rate. Then the cache is emptied automatically when the sequence of operations are
complete.
1.5.1.6 Intelligent Memory Management (IMM)
Intelligent Memory Management (IMM) technology is Intel’s unique UMA memory
manager architecture, consisting of these key elements:
• Tiled memory addressing capability
• Deep display buffer implementation
• Dynamic data management scheme
The memory addressing allows address remapping in the hardware for all graphics
surfaces including textures, frame buffer, Z buffer, and video surfaces. Deep display
buffers and dedicated screen refreshes improve visual performance, while the dynamic
data management scheme manages burst size and page closing policies for memory
accesses.
IMM reduces the aggregate processor latency and allows longer in-page bursts for
higher system performance. IMM also increases page coherency and improves
memory efficiency in texture loads, 2D blitters, color/Z, MPEG2 motion compression,
and other operations.
1.5.1.7 Video Mixing Renderer (VMR)
The Intel Extreme Graphics 2 controller features VMR technology. VMR is a process
where various data types can be blended together before being displayed. VMR allows
applications to bend and twist images such as 3D textures so that special effects such
as wipes, spins, and fades can be achieved.
1.5.1.8 PC/VCR Time Shifted Viewing
PC/VCR requires a TV-tuner add-in card and a third party application. PC/VCR time
shifted viewing allows the user to view and digitally record video pictures on their PC.
Users can view stored images while recording and by using time-shifted viewing they
can pause, resume, replay, and catch up to real time. The Intel Pentium 4 processor in
combination with the Intel 82865G GMCH optimizes performance so that the video
output is smooth without leaving any visual artifacts. Video tearing and corruption is
prevented by the use of multiple buffers within the Intel Extreme Graphics 2 controller.
1.5.1.9 Bi-cubic Filtering
Bi-cubic filtering is a new 4X4 filter that allows images to be generated more smoothly
in the 3D pipeline. The bi-cubic filter can be used to improve image quality for all 3D
texture engine components.
28
Product Description
1.5.1.10 AGP Digital Display (ADD) Card Support
The GMCH routes two 12-bit multiplexed DVO ports that are each capable of driving a
165 MHz pixel clock to the AGP connector. The DVO ports can be paired for dual
channel mode. In dual channel mode, the GMCH is capable of driving a 24-bit 330 MHz
pixel clock. When an AGP add-in card is used, the Intel Extreme Graphics 2 controller
is disabled and the AGP connector operates in AGP mode. When an ADD card is
detected, the Intel Extreme Graphics 2 controller is enabled and the AGP connector is
configured for DVO mode. DVO mode enables the DVO ports to be accessed by an
ADD card. ADD cards can support up to two display devices with the following
configurations:
• TV-Out
• Transition Minimized Differential Signaling (TMDS)
• Low Voltage Differential Signaling (LVDS)
• Single device operating in dual channel mode
INTEGRATOR’S NOTES
#
• Synchronous display is not supported when one of the display devices is a TV.
• Synchronous display with two digital displays is not supported.
• Digital Visual Interface (DVI) support is present only when an ADD card is installed.
1.5.2 Universal 0.8 V / 1.5 V AGP 3.0 Connector
The AGP connector supports the following:
• 4x, 8x AGP 3.0 add-in cards with 0.8 V I/O
• 1x, 4x AGP 2.0 add-in cards with 1.5 V I/O
• AGP Digital Display (ADD) cards
AGP is a high-performance interface for graphics-intensive applications, such as 3D
applications. While based on the PCI Local Bus Specification, Rev. 2.2, AGP is
independent of the PCI bus and is intended for exclusive use with graphical display
devices. AGP overcomes certain limitations of the PCI bus related to handling large
amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for nearly 100 percent efficiency
INTEGRATOR’S NOTES
#
• AGP 2x operation is not supported.
• Install memory in the DIMM sockets prior to installing the AGP video card to avoid
interference with the memory retention mechanism.
• The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0
cards only. Do not attempt to install a legacy 3.3 V AGP card. The AGP connector
is not mechanically compatible with legacy 3.3 V AGP cards.
