Overclocking may affect your system stability, or even cause damage to the components and devices of your system. It should be done at your own risk and expense. We are not responsible for possible damage caused by overclocking. ASRock 945GCM-S Motherboard CAUTION! FSB1333-CPU will operate in overclocking mode. Under this situation, PCIE frequency will also be overclocked to 115MHz. Besides, if you want to overclock the CPU you adopt from FSB800 to FSB1066, you need to adjust the jumpers. Please refer to page 14 for proper jumper settings. 2. About the setting of "Hyper Threading Technology", please check page 30 of "User Manual" in the support CD. 3. This motherboard supports Untied Overclocking Technology. Please read "Untied Overclocking Technology" on page 19 for details. 4. This motherboard supports Dual Channel Memory Technology. Before you implement Dual Channel Memory Technology, make sure to read the installation guide of memory modules on page 12 for proper installation. 5. Please check the table below for the CPU FSB frequency and its corresponding memory support frequency. CPU FSB Frequency Memory Support Frequency 1333 DDR2 533*, DDR2 667 1066 DDR2 533, DDR2 667 800 DDR2 400, DDR2 533, DDR2 667 533 DDR2 400, DDR2 533 * When you use a FSB1333-CPU on this motherboard, it will run at DDR2 500 if you adopt a DDR2 533 memory module. 6. Due to the chipset limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® XP, Windows® XP 64-bit, Windows® VistaTM and Windows® VistaTM 64-bit. 7. The maximum shared memory size is defined by the chipset vendor and is subject to change. Please check Intel® website for the latest information. 8.

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. 2. 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. 3. Hold components by the edges and do not touch the ICs. 4. Whenever you uninstall any component, place it on a grounded antstatic pad or in the bag that comes with the component. 5. 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. 2.1 CPU Installation For the installation of Intel 775-LAND CPU, please follow the steps below. ...
