Chapter 1 Main Features Note 1. USBPW0246_1 is for the internal USB connectors, USBPW1357_1 is for the rear USB ports. 2. The USB device wake-up feature requires a power supply that can provide 500mA on +5VSB lead for each USB port; otherwise, the system will not power up. 3. The total current consumed must not exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode. Keyboard and Mouse Jumper: KB/MS_PW This jumper allows you to enable or disable the Keyboard and Mouse wake-up feature. Set the jumper to pins 2-3(+5VSB) to wake up the computer from S3 and S4 sleep modes when you press a key on the keyboard or move the mouse, and a corresponding setting in the BIOS. 1 +5V (Default) 1 +5VSB KB/MS_PW Over Memory Frequency Jumper: JP1, JP2 (for G31MX Series) When you use the memory which support 1066, the jumpers are used to overclock memory frequency. At the same time, the overclock bound depend on CPU FSB, you can achieve the function as below. 1.When the CPU FSB is 1066MHz, set the JP1 pins to 2-3(as status 1), and set "CMOS Setup"->"Fox Central Control Unit"->"DRAM Configuration"->"DRAM Timing Selectable" to "Manual", "System Memory Frequency" will show 886 and 1066. 2.When the CPU FSB is 1333MHz, set the JP2 pins to 2-3(as status 2), and set "CMOS Setup"->"Fox Central Control Unit"->"DRAM Configuration"->"DRAM Timing Selectable" to "Manual", "System Memory Frequency" will show 1000. 1 JP1 1 1 JP1 1 1 JP1 1 JP2 Default JP2 JP2 Status 1 Status 2 19
