Step 3. Align fasteners with the motherboard
throughholes.
Step 4. Rotate the fastener clockwise, then press
down on fastener caps with thumb to install
and lock. Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise,
the heatsink cannot be secured on the motherboard.
Step 5. Connect the fan header with the CPU fan
connector on the motherboard.
Step 6. Secure excess cable with tie-wrap to ensure
cable does not interfere with fan operation or
contact other components.

16
2.4 Installation of Memory Modules (DIMM)
P4 Combo motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots.
