1.3 Processor
The board is designed to support the following processors:
•Intel Pentium 4 processor in an LGA775 processor socket with an 800 or 533 MHz system bus
•Intel Celeron processor in an LGA775 processor socket with a 533 MHz system bus
See the Intel web site listed below for the most up-to-date list of supported processors.
For information about… Refer to:
Supported processors for the D915PDT
board http://www.intel.com/design/motherbd/dt/dt_proc.htm
CAUTION
Use only the processors listed on web site above. Use of unsupported processors can damage the
board, the processor, and the power supply.
# INTEGRATOR’S NOTE
•Use only ATX12V-compliant power supplies.
•Refer to Table 3 on page 16 for a list of supported system bus frequency and memory speed
combinations.
For information about Refer to
Power supply connectors Section 2.7.2.1, page 51

Intel Desktop Board D915PDT Technical Product Specification

1.4 System Memory
The board has two DIMM sockets and support the following memory features:
•2.5 V (only) 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: 128 MB
•Non-ECC DIMMs
•Serial Presence Detect
•DDR 400 MHz and DDR 333 MHz 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…
DDR 400 800 MHz
DDR 333 (Note) 800 or 533 MHz
Note: When using an 800 MHz system bus frequency processor, DDR 333 memory is clocked at 320 MHz. This minimizes
system latencies to optimize system throughput.
NOTES
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 4 lists the supported DIMM configurations.

1.4.1 Memory Configurations
The Intel 82915P MCH supports two 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.
Figure 3 illustrates the memory channel and DIMM configuration.

1.5 Intel®915P Chipset
The Intel 915P chipset consists of the following devices:
•Intel 82915P Memory Controller Hub (MCH) with Direct Media Interface (DMI) interconnect
•Intel 82801FB I/O Controller Hub (ICH6) with DMI interconnect
•Firmware Hub (FWH)
The MCH is a centralized controller for the system bus, the memory bus, the PCI Express bus, and
the DMI interconnect. The ICH6 is a centralized controller for the board’s I/O paths. The FWH

1.5.1 USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and
EHCI-compatible drivers.
The ICH6 provides the USB controller for all ports. The port arrangement is as follows:
•Four ports are implemented with dual stacked back panel connectors adjacent to the audio
connectors. These connectors are yellow, indicating that they support USB anti-theft circuitry.
•Four ports are routed to two separate front panel USB connectors. These connectors do not
support USB anti-theft circuitry.
 NOTE
USB anti-theft circuitry requires the use of Intel®Platform Administration Technology software.
Contact your Intel representative for more information.
 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.
