L2 Cache
Display the information of L2 Cache per Core.
L3 Cache
Display the information of total L3 Cache per socket.
CPU Speed
Display the current installed CPU speed.
64-bit
Display the supported infprmation of installed CPU.
Hyper-threading
The Intel Hyper Threading Technology allows a single processor to execute two or more separate
threads concurrently. When hyper-threading is enabled, multi-threaded software applications can
execute their threads, thereby improving performance.
Options available: Enabled/Disabled. Default setting is Enabled.
Limit CPUID Maximum
When enabled, the processor will limit the maximum CPUID 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.
Options available: Enabled/Disabled. Default setting is Disabled.
Execute Disable Bit
When enabled, the processor prevents the execution of code in data-only memory pages. This provides
some protection against buffer overow attacks.
When disabled, the processor will not restrict code execution in any memory area. This makes the pro-
cessor more vulnerable to buffer overow attacks.
Options available: Enabled/Disabled. Default setting is Disabled.
Intel Virtualization Technology
Select whether to enable the Intel Virtualization Technology function. VT allows a single platform to run
multiple operating systems in independent partitions.
Options available: Enabled/Disabled. Default setting is Disabled.
Energy Performance
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 Efcient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS
Default setting is Performance.
