how to install Asus B660M-C D4-CSM Desktop Motherboard

• Prepare your workspace with a clean, static-free surface. Gather your CPU, cooler, memory, power supply, and case hardware.
• Install the CPU into the LGA-1700 socket on the motherboard, aligning the notches properly and securing the lever. Apply a small amount of thermal paste if your cooler requires it, then mount the CPU cooler according to its instructions for proper contact and cooling.
• Open the RAM slots and align the DDR4 modules with the notches. Press firmly until the modules click into place and are fully seated in all four banks. Ensure the memory is installed in the correct slots for your desired dual-channel or quad-channel configuration as specified by the motherboard manual.
• Place the motherboard into the case, align with the standoffs, and secure using screws. Connect the 24-pin ATX power connector and the 8-pin (or 4+4) CPU power connector from your power supply. Connect case fans and any optional cooling devices.
• Attach storage drives (SSD/HDD) using the appropriate SATA or M.2 slots as available, then connect data cables and power. Connect the front-panel USB, audio, and power/reset buttons to their corresponding headers on the motherboard. Boot into the BIOS to verify hardware detections, set boot order, and configure memory XMP profiles if desired. Save changes and exit to start your operating system installation.
