Displays the support information for the installed processor. Cache Information L1 Data Cache / L1 Code Cache / L2 Cache / L3 Cache CPU Speed / 64-bit Displays the technical specifications for the installed processor. Displays the technical specifications for the installed processor. Allows you to determine whether to enable all CPU cores. When enabled, the processor will limit the maximum COUID input values to 03h when queried, even if the processor suppports a higher CPUID input value. When disabled, the processor will return the actual maximum CPUID input value of the processor when queried. Default setting is Disabled. Active Processor Cores (Note) Limit CPUID Maximum (Note) This item is present only if you install a CPU that supports this feature. For more information about Intel CPUs' unique features, please visit Intel's website. BIOS Setup - 48 - Execute Disable Bit When enabled, the processor prevents the execution of code in data-only memory pages. This provides some protection against buffer overflow attacks. When disabled, the processor will not restrict code execution in any memory area. Options available: C0/C1/C6/C7/No Limit. Energy Performance Bias is Intel CPU function. The larger value in MSR_ENERGY_PERFORMANCE_BIAS register, CPU will save more power but lose more performance. Note: This register will be changed by OS too if OS support it like Windows 2008 or newer Linux. Options available: Performance : Write value 0 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Performance: Write value 7 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Energy: Write value 11 into MSR_ENERGY_PERFORMANCE_BIAS Energy Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS Default setting is Performance. Package C State Limit Energy Performance (Note) This item is present only if you install a CPU that supports this feature.
