1.4 System Memory
The board has four DIMM sockets and support the following memory features:
• 1.8 V (only) DDR2 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.
• 8 GB maximum total system memory. Refer to Section
information on the total amount of addressable memory.
• Minimum total system memory: 512 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 667 or DDR2 533 MHz SDRAM DIMMs
NOTE
A minimum of 512 MB of system memory is required to fully enable both the onboard
graphics and the manageability engine.
2.1.1 on page 41 for
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
NOTE
Regardless of the DIMM type used, the memory frequency will either be equal to or
less than the processor system bus frequency. For example, if DDR2 667 memory is
used with a 533 MHz system bus frequency processor, the memory will operate at
533 MHz.
Table 4 lists the resulting operating memory frequencies based on the
combination of DIMMs and processors.

DDR2 667 800 MHz 667 MHz
DDR2 667 1066 MHz 667 MHz
1.4.1 Memory Configurations
The Intel 82Q963 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.

Regardless of the memory configuration used (dual channel, single channel, or flex
mode), DIMM 0 of Channel A must always be populated. This is a requirement of the
ICH8 Manageability Engine feature.

Zoom Utility
1.5.1.2 Dynamic Video Memory Technology (DVMT)
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. Up to 256 MB of system memory can be
allocated to DVMT on systems that have 512 MB or more of total system 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.
24
Product Description
NOTE
The use of DVMT requires operating system driver support.
1.5.1.3 Configuration Modes
A list of supported modes for the Intel GMA 3000 graphics controller is available as a
downloadable document.
For information about Refer to
Supported video modes for the board Section 1.2, page 15
1.5.2 USB
The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCIand EHCI-compatible drivers.
The ICH8 provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Four ports are routed to two separate front panel USB headers
NOTE
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable. Use
shielded cable that meets the requirements for full-speed devices.
For information about Refer to
The location of the USB connectors on the back panel Figure 15, page 49
The location of the front panel USB headers Figure 16, page 50
1.5.3 Serial ATA Interfaces
The board provides four Serial ATA (SATA) connectors, which support one device per
connector.
1.5.3.1 Serial ATA Support
The ICH8’s Serial ATA controller offers four 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 four 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.
25
Intel Desktop Board DQ963FX Technical Product Specification
Native mode is the preferred mode for configurations using the Windows* XP and
Windows 2000 operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adaptors or
power supplies equipped with low-voltage power connectors.
For more information, see:
For information about Refer to
The location of the Serial ATA connectors Figure 16, page 50
http://www.serialata.org/.
1.5.4 Parallel IDE Interface
The Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The
Parallel ATA IDE 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/sec.
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 33 MB/sec.
• ATA-66: DMA protocol on IDE bus supporting host and target throttling and
transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is
device driver compatible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
• ATA-133: DMA protocol on IDE bus allows host and target throttling. The ATA-133
logic is designed to achieve read transfer rates up to 133 MB/sec and write transfer
rates in excess of 100 MB/sec.
NOTE
ATA-66, ATA-100, and ATA-133 are faster timings and require a specialized cable to
reduce reflections, noise, and inductive coupling.
The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives)
and ATA devices. 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.

Product Description
1.5.5 Real-Time Clock, CMOS SRAM, and Battery
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.
1.6 Legacy I/O Controller
The I/O controller provides the following features:
• One serial port
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) support
