[. . . ] These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ? [. . . ] A fan with a 4-pin connector as shown in Figure 13, A is recommended; however, a fan with a 3-pin connector (Figure 13, B) can be used. However, since a fan with a 3-pin connector cannot use the onboard fan control, the fan will always operate at full speed. Figure 13. Connecting the Processor Fan Heat Sink Cable Removing the Processor For instructions on how to remove the processor fan heat sink and processor, refer to the processor installation manual. 37 Intel Desktop Board DQ45CB Product Guide Installing and Removing Memory Intel Desktop Board DQ45CB has four 240-pin DDR2 DIMM sockets arranged as DIMM 0 and DIMM 1 in both Channel A and Channel B. NOTE Regardless of the memory configuration used (dual or single channel), Channel A, DIMM 0 must always be populated. This is a requirement of the ICH10DO Manageability Engine feature. 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 (see Figure 14) in DIMM 0 (blue) of channels A and B. Figure 14. Dual Channel Memory Configuration with Two DIMMs 38 Installing and Replacing Desktop Board Components If additional memory is to be used, install another matched pair of DIMMs in DIMM 1 (black) in channels A and B (see Figure 15). Figure 15. Dual Channel Memory Configuration with Four DIMMs Three DIMMs If you want to use three DIMMs in a dual-channel configuration, 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 16). Figure 16. Dual Channel Memory Configuration with Three DIMMs NOTE All other memory configurations will result in single channel memory operation. 39 Intel Desktop Board DQ45CB Product Guide Installing DIMMs To make sure you have the correct DIMM, place it on the illustration of the DDR2 DIMM in Figure 17. Use DDR2 DIMMs 40 Installing and Replacing Desktop Board Components To install a DIMM, follow these steps: 1. Remove the computer?s cover and locate the DIMM sockets (see Figure 18). Figure 18. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position.
