Desktop Board Features Processor CAUTION Failure to use the appropriate power supply and/or not connecting the 12 V (2 x 2 pin) power connector to the desktop board may result in damage to the board or the system may not function properly. Desktop Board D945GCPE supports an Intel processor in the LGA775 package. Processors are not included with the desktop board and must be purchased separately. The processor connects to the desktop board through the LGA775 socket.
Intel Desktop Board D945GCPE Product Guide 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 533 memory is used with an 800 MHz system bus frequency processor, the memory will operate at 533 MHz.

Intel Desktop Board D945GCPE Product Guide RJ-45 LAN Connector LEDs Two LEDs are built into the RJ-45 LAN connector located on the back panel (see Figure 2). These LEDs indicate the status of the LAN. Figure 2. LAN Connector LEDs Table 3 describes the LED states when the board is powered up and the LAN subsystem is operating. Table 3.
Desktop Board Features Enhanced IDE Interface The desktop board’s IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. The interface supports: • • • • Up to two IDE devices (such as hard drives) ATAPI-style devices (such as CD-ROM drives) Older PIO Mode devices Ultra DMA-33 and ATA-66/100 protocols Serial ATA The desktop board supports two Serial ATA channels (3.0 Gb/s) via ICH7, connecting one device per channel.
Intel Desktop Board D945GCPE Product Guide PCI* Auto Configuration If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card. Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer.
Desktop Board Features Chassis Intrusion Detection The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 1, S on page 11 for the location of the chassis intrusion header.
Intel Desktop Board D945GCPE Product Guide Fan Headers The function/operation of the fans is as follows: • • • • • The fans are on when the computer is in the ACPI S0 or S1 state. The fans are off when the computer is in the ACPI S3, S4, or S5 state. Each fan header is wired to a tachometer input of the hardware monitoring and control device. All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. All fan headers have a +12 V dc connection.
Desktop Board Features +5 V Standby Power Indicator CAUTION If the AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices. The desktop board’s standby power indicator, shown in Figure 3, is lit when there is standby power still present on the board even when the computer appears to be off.
Intel Desktop Board D945GCPE Product Guide Wake from USB NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. USB bus activity wakes the computer from an ACPI S1 or S3 state. Wake from PS/2* Keyboard/Mouse PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state. PME# Signal Wake-up Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state.

Intel Desktop Board D945GCPE Product Guide Installation Precautions When you install and test the Intel desktop board, observe all warnings and cautions in the installation instructions.
Installing and Replacing Desktop Board Components Installing the I/O Shield The desktop board comes with an I/O shield. When installed in the chassis, the shield blocks radio frequency transmissions, protects internal components from dust and foreign objects, and promotes correct airflow within the chassis. Install the I/O shield before installing the desktop board in the chassis. Place the shield inside the chassis as shown in Figure 4. Press the shield into place so that it fits tightly and securely.
Intel Desktop Board D945GCPE Product Guide Installing and Removing the Desktop Board CAUTION Only qualified technical personnel should do this procedure. Disconnect the computer from its power source before performing the procedures described here. Failure to disconnect the power before you open the computer can result in personal injury or equipment damage. Do not lift or handle the desktop board by the chipset heat sink.
Installing and Replacing Desktop Board Components Installing and Removing a Processor Instructions on how to install the processor on the desktop board are given below. Installing a Processor CAUTION Before installing or removing the processor, make sure the AC power has been removed by unplugging the power cord from the computer; the standby power indicator should not be lit (see Figure 3 on page 21). Failure to do so could damage the processor and the board.
Intel Desktop Board D945GCPE Product Guide 3. Lift the load plate (Figure 7, A). Do not touch the socket contacts (Figure 7, B). Figure 7. Lift the Load Plate 4. Remove the plastic protective socket cover from the load plate (see Figure 8). Do not discard the protective socket cover. Always replace the socket cover if the processor is removed from the socket. Figure 8.
Installing and Replacing Desktop Board Components 5. Remove the processor from the protective processor cover. Hold the processor only at the edges, being careful not to touch the bottom of the processor (see Figure 9). Do not discard the protective processor cover. Always replace the processor cover if the processor is removed from the socket. Figure 9. Remove the Processor from the Protective Processor Cover 6. Hold the processor with your thumb and index fingers oriented as shown in Figure 10.
Intel Desktop Board D945GCPE Product Guide 7. Pressing down on the load plate (Figure 11, A) close and engage the socket lever (Figure 11, B). Figure 11. Close the Load Plate Installing the Processor Fan Heat Sink Desktop Board D945GCPE has an integrated processor fan heat sink retention mechanism (RM).
Installing and Replacing Desktop Board Components Connecting the Processor Fan Heat Sink Cable Connect the processor fan heat sink cable to the 4-pin processor fan header (see Figure 12). A fan with a 4-pin connector as shown in Figure 12, A is recommended; however, a fan with a 3-pin connector (Figure 12, B) can be used. Since the 3-pin fan cannot use the onboard fan control, the fan will always operate at full speed. Figure 12.
Intel Desktop Board D945GCPE Product Guide Installing and Removing Memory NOTE To be fully compliant with all applicable Intel SDRAM memory specifications, the board requires DIMMs that support the Serial Presence Detect (SPD) data structure. You can access the PC Serial Presence Detect Specification at: http://www.intel.com/technology/memory/ddr/specs/dda18c32_64_128x72ag_a.pdf The desktop board has two 240-pin DDR2 DIMM sockets providing Channel A and Channel B.
Installing and Replacing Desktop Board Components To make sure you have the correct DIMM, place it on the illustration of the DDR2 DIMM in Figure 14. All the notches should match with the DDR2 DIMM. Figure 14.
Intel Desktop Board D945GCPE Product Guide Installing DIMMs To install a DIMM, follow these steps: 1. Observe the precautions in "Before You Begin" on page 23. 2. Turn off all peripheral devices connected to the computer. Turn off the computer and disconnect the AC power cord. 3. Remove the computer’s cover and locate the DIMM sockets (see Figure 15). Figure 15. Installing a DIMM 4. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position. 5.
Installing and Replacing Desktop Board Components Removing DIMMs To remove a DIMM, follow these steps: 1. 2. 3. 4. 5. Observe the precautions in "Before You Begin" on page 23.
