Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Pre-installation Precautions Take note of the following precautions before you install motherboard components or change any motherboard settings. · Make sure to unplug the power cord before installing or removing the motherboard components. Failure to do so may cause physical injuries and damages to motherboard components. · In order to avoid damage from static electricity to the motherboard's components, NEVER place your motherboard directly on a carpet. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle the components. · Hold components by the edges and do not touch the ICs. · Whenever you uninstall any components, place them on a grounded anti-static pad or in the bag that comes with the components. · When placing screws to secure the motherboard to the chassis, please do not overtighten the screws! Doing so may damage the motherboard. 11 English 2.1 Installing the CPU 1. Before you insert the 1700-Pin CPU into the socket, please check if the PnP cap is on the socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged. 2. Unplug all power cables before installing the CPU. 1 A B 2 3 English 12 B660M-ITX/ac 4 5 6 7 English 13 Please save and replace the cover if the processor is removed. The cover must be placed if you wish to return the motherboard for after service. 14 English 2.2 Installing the CPU Fan and Heatsink B660M-ITX/ac 1 2 CPU_FAN 15 English 2.3 Installing Memory Modules (DIMM) This motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots, and supports Dual Channel Memory Technology. 1. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR4 DIMM pairs. 2. It is unable to activate Dual Channel Memory Technology with only one memory module installed. 3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot; otherwise, this motherboard and DIMM may be damaged. The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation. 16 English B660M-ITX/ac 1 2 3 17 English 2.4 Expansion Slot (PCI Express Slot) There is 1 PCI Express slot slot on the motherboard. Before installing an expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation. PCIe slot: PCIE1 (PCIe 4.0 x16 slot) is used for PCI Express x16 lane width graphics cards. 18 English B660M-ITX/ac 2.5 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on the pins, the jumper is "Short". If no jumper cap is placed on the pins, the jumper is "Open". Clear CMOS Jumper (CLRMOS1) (see p.6, No. 16) 2-pin Jumper CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short the pins on CLRMOS1 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. Please be noted that the password, date, time, and user default profile will be cleared only if the CMOS battery is removed. Please remember toremove the jumper cap after clearing the CMOS. English 19 2.6 Onboard Headers and Connectors Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard.
