    CPU Voltage Selection


  • JP13 for CPU I/O and chipset voltage selection
  • JP14 for CPU core voltage selection
  • JP8 for MMX or split power plane CPU


    Please check your CPU voltage requirements before doing the jumper setting below.


    CAUTION:

    For MMX or other split power plane CPU, JP8 must be fully opened before turning on the system power. Failure to do so may cause damages to your CPU.


    CPU Type I/O Voltage JP13 Core Voltage JP14 JP8
    Intel Pentium
    Cyrix/IBM 6x86
    AMD K5    		 3.5V [1-2] 3.5V [1-2] [1-2],[3-4],
    [5-6] and [7-8]
    Intel Pentium with MMX
    Cyrix/IBM 6x86L    		 3.5V [1-2] 2.8V [2-3] Fully open



    CMOS Reset

    JP9 is used to clear the content of CMOS. After reset, all system BIOS configuration will be lost.

    Description JP9
    CMOS Clear [2-3]
    Normal operation [1-2] (default)
