Boot Failure Guard Count Enable or disable the feature of Boot Failure Guard Count. Spread Spectrum This item should always be [Auto] for better system stability. CPU Ratio Setting If the ratio status is unlocked, you will find this item appear to allow you changing the ratio value of this motherboard. QPI Frequency Use this option to adjust QPI (QuickPath Interconnect) frequency. The default value is [Auto]. Uncore Frequency Use this option to adjust uncore frequency. The value of uncore frequency should be at least double of DRAM frequency. For exanple, if the DRAM frequency is [800MHz DDR3_1600], uncore frequency should be above [3200MHz]. Configuration options: [Auto], [1600MHz], [1866MHz], [2133MHz], [2400MHz], [2666MHz], [2933MHz], [3200MHz], [3466MHz], [3733MHz], [4000MHz] and [4266MHz]. The default value is [Auto]. DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may select [Auto], [400MHz DDR3_800], [533MHz DDR3_1066], [666MHz DDR3_1333], [800MHz DDR3_1600], [933MHz DDR3_1866] or [1066MHz DDR3_2133].
