The Desktop Board has two 240-pin DDR3 DIMM sockets providing Channel A and Channel B. For optimum dual-channel performance, install a matched pair of DIMMs equal in speed and size (see Figure 13). Figure 13. Dual-Channel Memory Configuration Example NOTE All other memory configurations will result in single-channel memory operation. 36 Installing and Replacing Desktop Board Components Installing DIMMs To make sure you have the correct DIMM, place it on the illustration of the DDR3 DIMM in Figure 14. Use DDR3 DIMMs 37 Intel Desktop Board DG41KR Product Guide To install a DIMM, follow these steps: 1. Remove the computer?s cover and locate the DIMM sockets (see Figure 15). Figure 15. 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 15). 38 Installing and Replacing Desktop Board Components 7. When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips snap into place. Replace the computer?s cover and reconnect the AC power cord. Removing DIMMs To remove a DIMM, follow these steps: 1. Attach the cable end labeled P1 to the diskette drive connector on the Intel Desktop Board (Figure 20, A).
