CAUTION
Use only the processors listed below. Use of unsupported processors can damage the board, the
processor, and the power supply. See Intel’s World Wide Web site for the most up-to-date list of
supported processors for this board.
The board provides an mPGA478 processor socket. Table 4 lists the supported processors. All
supported onboard memory can be cached. See the processor’s data sheet for cachability limits.

INTEGRATOR’S NOTES
• Use only ATX12V- or SFX12V-compliant power supplies with the board. ATX12V and
SFX12V power supplies have an additional power lead that provides required supplemental
power for the processor. Always connect the 20-pin and 4-pin leads of ATX12V and SFX12V
power supplies to the corresponding connectors, otherwise the board will not boot.
• Do not use a standard ATX power supply. The board will not boot with a standard ATX
power supply.

Processor support Section 1.3, page 16
Power supply connectors Section 2.8.2.2, page 50

1.7 System Memory
The Desktop Board D845GLVA has two DIMM sockets and supports the following memory
features:
• 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
• Unbuffered single-sided or double-sided DIMMs
• Maximum total system memory: 2 GB; minimum total system memory: 64 MB
• DDR266/200 MHz SDRAM DIMMs only
• Serial Presence Detect (SPD)
CAUTION
Do not use ECC DIMMs with this board. Using ECC DIMMs could damage the board.
INTEGRATOR’S NOTES
• Registered DIMMs are not supported.
• Double-sided x16 DIMMs are not supported.
Product Description
• If a full-length PCI add-in card is installed in PCI bus connector 1 (the PCI bus connector
closest to the processor), remove the add-in card before installing or upgrading memory
to avoid interference with the memory retention mechanism.
• This board has been designed to support DIMMs based on 512 Mbit technology for a
maximum onboard capacity of up to 2 GB, but this technology has not been validated
(currently validated up to 1.0 GB) on this board. Please refer to the following Intel web
sites for the latest lists of tested memory:
http://developer.intel.com/design/motherbd/va/va_mem.htm
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.

1.8.1.1 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 (up
to 64 MB) for maximum 2-D/3-D graphics performance.
DVMT uses a 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 the buffers needed for
performing graphics functions.
NOTE
✏
The use of DVMT requires operating system driver support.
For information about Refer to
Obtaining the DVMT white paper http://developer.intel.com/products/desktop/chipsets/graphics/index.htm

Intel Desktop Board D845GLVA Technical Product Specification
1.8.1.2 Zone Rendering Technology (ZRT)
The Intel Extreme Graphics 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
For information about Refer to
Obtaining the Zone Rendering white paper http://developer.intel.com/design/chipsets/845gl/
1.8.2 USB
The Desktop Board supports up to four USB 2.0 ports, fully support UHCI and EHCI, and use
UHCI- and EHCI-compatible drivers. For more than four USB devices, an external hub can be
connected to any of the ports.
The ICH4 provides the USB controller for all ports. The port arrangement is as follows:
• Two ports are implemented with stacked back panel connectors, adjacent to the audio
connectors
• Two ports are routed to the front panel USB connector
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.
1.8.3 IDE Interfaces
The ICH4’s IDE controller has two independent bus-mastering IDE interfaces that can be
independently enabled. The IDE interfaces support 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 ICH4’s ATA-100
logic can achieve transfer rates up to 100 MB/sec.
28
Product Description
INTEGRATOR’S NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections,
noise, and inductive coupling.
The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices.
The BIOS supports 48-bit Logical Block Addressing (LBA) and Extended Cylinder Head Sector
(ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The Desktop Board supports Laser Servo (LS-120) diskette technology through the IDE interfaces.
The BIOS supports booting from an LS-120 drive.
NOTE
✏
The BIOS will always recognize an LS-120 drive as an ATAPI floppy drive. To ensure correct
operation, do not configure the drive as a hard disk drive.
1.8.4 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.
INTEGRATOR’S NOTE
If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS
RAM at power-on.
