For power-saving sake, it is strongly recommended to enable AMD's Cool `n' QuietTM technology under Windows system. See APPENDIX on page 37 of "User Manual" in the Support CD to enable AMD's Cool `n' QuietTM technology. While CPU overheat is detected, the system will automatically shutdown. Before you resume the system, please check if the CPU fan on the motherboard functions properly and unplug the power cord, then plug it back again. To improve heat dissipation, remember to spray thermal grease between the CPU and the heatsink when you install the PC system. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! Power Management for USB 2.0 works fine under Microsoft® Windows® XP SP1 / 2000 SP4. It may not work properly under Microsoft® Windows® 98 / ME. For microphone input, this motherboard supports mono modes. For audio output, this motherboard supports 2-channel, 4-channel, 6-channel, and 8channel modes. Please check the table on page 3 for proper connection. Although this motherboard offers stepless control, it is not recommended to perform over-clocking. Frequencies other than the recommended CPU FSB frequencies may cause the instability of the system or damage the CPU. 2. 3. 4. 5. 6. English English 6 ASRock 939A8X-M Motherboard 2. Installation Pre-installation Precautions Take note of the following precautions before you install motherboard components or change any motherboard settings. 1. Unplug the power cord from the wall socket before touching any component. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components. To avoid damaging the motherboard components due to static electricity, NEVER place your motherboard directly on the carpet or the like. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle components. Hold components by the edges and do not touch the ICs. Whenever you uninstall any component, place it on a grounded antstatic pad or in the bag that comes with the component. When placing screws into the screw holes to secure the motherboard to the chassis, please do not over-tighten the screws! Doing so may damage the motherboard. 2. 3. 4. 5. 2.1 Step 1. Step 2. Step 3. CPU Installation Unlock the socket by lifting the lever up to a 90° angle. Position the CPU directly above the socket such that its marked corner matches the base of the socket lever. Carefully insert the CPU into the socket until it fits in place. The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to avoid bending of the pins. Step 4. 7 ASRock 939A8X-M Motherboard English Step 5. When the CPU is in place, press it firmly on the socket while you push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. Install CPU fan and heatsink. For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink vendors. 2.2 Installation of Memory Modules (DIMM) 939A8X-M motherboard provides four 184-pin DDR (Double Data Rate) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR DIMM pair in the slots of the same color. In other words, you have to install identical DDR DIMM pair in Dual Channel A (DDR1 and DDR2; Blue slots; see p.2 No. 6) or identical DDR DIMM pair in Dual Channel B (DDR3 and DDR4; Black slots; see p.2 No. 7), so that Dual Channel Memory Technology can be activated. This motherboard also allows you to install four DDR DIMMs for dual channel configuration, and please install identical DDR DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration Table below. Dual Channel Memory Configurations DDR1 (Blue Slot) Populated Populated DDR2 (Blue Slot) Populated Populated DDR3 (Black Slot) Populated Populated DDR4 (Black Slot) Populated Populated (1) (2) (3)* * For the configuration (3), please install identical DDR DIMMs in all four slots. * It is recommended to install DDR3 and DDR4 (black slots) first. Then to install in DDR1 and DDR2. (That is, to populate DDR DIMM from the far side of CPU towards to the near side of CPU.) 1. 2. 3. If you want to install two different memory modules, for optimal compatibility and reliability, it is recommended to install them in the slots of different color. In other words, install them either in DDR1 and DDR3. If only one memory module or three memory modules are installed in the DDR DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory Technology. If a pair of memory modules is NOT installed in the same Dual Channel, for example, installing a pair of memory modules in DDR1 and DDR3, it is unable to activate the Dual Channel Memory Technology . English 8 ASRock 939A8X-M Motherboard Installing a DIMM Please make sure to disconnect power supply before adding or removing DIMMs or the system components. STEP 1: STEP 2: Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot. 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. STEP 3: Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated. 9 ASRock 939A8X-M Motherboard English 2.3 Expansion Slots (PCI and AGP Slots) There are 3 PCI slots and 1 AGP slot on 939A8X-M motherboard. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. AGP slot: The AGP slot is used to install a graphics card. The ASRock AGP slot has a special design of clasp that can securely fasten the inserted graphics card. Please do NOT use a 3.3V AGP card on the AGP slot of this motherboard! It may cause permanent damage! For the voltage information of your graphics card, please check with the graphics card vendors. Installing an expansion card Step 1. Before installing the 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 ...
