1.6 System Memory
1.6.1 Memory Features
The Desktop Board D865PERL has four 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 with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 4 GB maximum total system memory. Refer to Section 2.2.1 on page 51 for information on
the total amount of addressable memory.
• Minimum total system memory: 64 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR400, DDR333, and DDR266 SDRAM DIMMs
Table 4 lists the supported system bus frequency and memory speed combinations.
Table 4. 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 800 or 533 MHz (Note)
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.
✏ NOTES
• Remove the AGP video card before installing or upgrading memory to avoid interference with
the memory retention mechanism.
• 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.

• 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 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
28
Product Description
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 specification-compatible cards or
1.5 V AGP 2.0 specification-compatible 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.
For information about Refer to
The location of the AGP connector Figure 1, page 14
Obtaining the Accelerated Graphics Port Interface Specification Section 1.4, page 17
1.7.2 USB
The Desktop Board D865PERL supports up to eight USB 2.0 ports, supports UHCI and EHCI, and
uses UHCI- and EHCI-compatible drivers.
The ICH5/ICH5-R 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 PS/2
connectors
• Two ports are implemented with stacked back panel connectors, adjacent to the audio
connectors
• Four ports are routed to two front panel USB connectors
NOTES
✏
• 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.
• Native USB 2.0 support has been tested with drivers for Windows 2000 (with Service Pack 3)
and Windows XP (with Service Pack 1) and is not currently supported by any other operating

Intel Desktop Board D865PERL Technical Product Specification
1.7.3 IDE Support
The board provides four IDE interface connectors:
• Two Parallel ATA IDE connectors, which support a total of four devices (two per connector)
• Two Serial ATA IDE connectors, which support one drive per connector
1.7.3.1 Parallel ATA IDE Interfaces
The ICH5’s Parallel ATA IDE controller has two independent bus-mastering Parallel ATA IDE
interfaces that can be independently enabled. The Parallel ATA 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 ICH5’s ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.
NOTE
✏
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections,
noise, and inductive coupling.
The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA
devices using the transfer modes listed in Section 4.4.4.1 on page 105.
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.
The Desktop Board D865PERL supports Laser Servo (LS-120) diskette technology through the
Parallel ATA 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.
For information about Refer to
The location of the Parallel ATA IDE connectors Figure 22, page 68
1.7.3.2 Serial ATA Interfaces
The ICH5’s Serial ATA controller offers two independent Serial ATA ports with a theoretical
maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a
maximum of two Serial ATA devices. A point-to-point interface is used for host to device
connections, unlike 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
