BIOS Setup
(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.
L3 Cache
Display the total L2 cache memory of the installed processor in megabytes. This item appears when the
installed processor supports L3 .
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 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.
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 overflow attacks.
When disabled, the processor will not restrict code execution in any memory area. This makes the pro
-
cessor more vulnerable to buffer overflow attacks.
Options available: Enabled/Disabled. Default setting is
Enabled
.
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
Enabled
.
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 Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS
Default setting is
Performance
