Date January 2006 If an FCC declaration of conformity marking is present on the board, the following statement applies: FCC Declaration of Conformity This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. For questions related to the EMC performance of this product, contact: Intel Corporation 5200 N. E. [. . . ] Align notches (see Figure 10, G) with the socket see (Figure 10, H). Lower the processor straight down without tilting or sliding the processor in the socket. G G H F H F OM19105 Figure 10. While pressing down on the load plate (Figure 11, I), close and engage the socket lever (Figure 11, J). J I OM17215 Figure 11. Close the Load Plate 30 Installing and Replacing Desktop Board Components Installing the Processor Fan Heat Sink Desktop Board D945PWM has an integrated processor fan heat sink retention mechanism (RM). For instructions on how to attach the processor fan heat sink to the integrated processor fan heat sink RM, refer to the boxed processor manual or the Intel World Wide Web site at: The Boxed Intel Pentium 4 Processor in the 775-Land Package Connecting the Processor Fan Heat Sink Cable Connect the processor fan heat sink cable to the 4-pin processor fan connector (see Figure 12). OM19106 Figure 12. Connecting the Processor Fan Heat Sink Cable to the Processor Fan Connector Removing the Processor For instructions on how to remove the processor fan heat sink and processor, refer to the processor installation manual or the Intel World Wide Web site at: The Boxed Intel Pentium 4 Processor in the 775-Land Package 31 Intel Desktop Board D945PWM 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 four 240-pin DDR2 DIMM sockets arranged as DIMM 0 (blue) and DIMM 1 (black) in both Channel A and Channel B. Guidelines for Dual Channel Memory Configuration Before installing DIMMs, read and follow these guidelines for dual channel configuration. Two or Four DIMMs Install a matched pair of DIMMs equal in speed and size in DIMM 0 (blue) of both channels A and B (see Figure 13). Channel A 1 GB, 533 MHz Channel B 1 GB, 533 MHz DIMM 0 DIMM 1 DIMM 0 DIMM 1 Figure 13. Dual Configuration Example 1 If additional memory is to be used, install another matched pair of DIMMs in DIMM 1 (black) in both channels A and B (see Figure 14). Channel A 256 MB, 533 MHz 512 MB, 533 MHz Channel B 256 MB, 533 MHz 512 MB, 533 MHz DIMM 0 DIMM 1 DIMM 0 DIMM 1 Figure 14. Dual Configuration Example 2 32 Installing and Replacing Desktop Board Components Three DIMMs Install a matched pair of DIMMs equal in speed and size in DIMM 0 (blue) and DIMM 1 (black) of channel A. Install a DIMM equal in speed and total size of the DIMMs installed in channel A in either DIMM 0 or DIMM 1 of channel B (see Figure 15). Channel A 256 MB, 533 MHz 256 MB, 533 MHz Channel B 512 MB, 533 MHz DIMM 0 DIMM 1 DIMM 0 DIMM 1 Figure 15. Dual Configuration Example 3 NOTE All other memory configurations will result in single channel memory operation. 33 Intel Desktop Board D945PWM Product Guide Installing DIMMs NOTE Install memory in the DIMM sockets prior to installing a PCI Express video card to avoid interference with the memory retention mechanism. Observe the precautions in "Before You Begin" on page 23. Turn off all peripheral devices connected to the computer. Turn off the computer and disconnect the AC power cord. Remove the computer's cover and locate the DIMM sockets (see Figure 16). OM19107 Figure 16. Remove the PCI Express video card if it interferes with the DIMM retaining clips from being easily opened and closed. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position. Holding the DIMM by the edges, remove it from its anti-static package. Align the small notch at the bottom edge of the DIMM with the keys in the socket (see inset in Figure 16). Insert the bottom edge of the DIMM into the socket. When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips snap into place. Make sure the clips are firmly in place.
