Intel Desktop Board DQ965CO Product Guide Installing and Removing Memory CAUTION When connected to AC power, the memory slots on the board will be powered and in use. A red LED, located near the memory slots, will be lit if the memory slots are powered. Installing or removing memory from the board while the memory slots are powered may result in damage to both memory and board. Before installing or removing memory, disconnect the system from AC power and wait for the LED to go off before proceeding. 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 Desktop Board DQ965CO has four 240-pin DDR2 DIMM sockets arranged as DIMM 0 and DIMM 1 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. NOTE The Intel® Management Engine in the chipset requires memory to be populated in Channel A, DIMM 0 in order for it to enable Intel Quiet System Technology and Intel Active Management Technology. Two or Four DIMMs Install a matched pair of DIMMs equal in speed and size (see Figure 16) in DIMM 0 (blue) of both channels A and B. Figure 16. Dual Channel Memory Configuration Example 1 38
