Socket 0 CPU Information
This item contains detailed information about the CPU, including the CPU manufacturer, model,
frequency, L1 cache size, and L2 cache size.
CPU Speed
This item shows the processor speed.
64-bit
This item shows whether 64-bit operations are supported.
Limit CPUID Maximum
CPUID refers to CPU information, including model number, CPU family, cache size, clock speed and
brand, as well as transistor number, pin type, size, etc. In the BIOS setup options of the Intel platform, it
is usually Limit CPUID MAX to 3. The meaning is: limit the execution of the CPUID instruction to
return a value greater than 3. Because return values greater than 3 may cause some operating system
wrong, generally set this option to [Disabled] on Windows systems for better overclocking. The default
value is [Disabled].
Execute Disabled Bit
The Execution Disable bit is a hardware feature of the Intel CPU that enables the CPU to avoid certain
malicious attacks based on buffer overflow viruses. In addition, the execution of the prohibition bit
requires Windows XP SP2, Windows Server 2003 SP1 and other OS to work properly. The
implementation principle is that the processor divides several areas in memory, some areas can execute
application code, while others do not allow. The setting items are Disabled/Enabled, and the default is
Enabled.
Intel Virtualization Technology
Intel Virtualization is the system hypothesis technology used in Intel's CPU. It enables multiple OS to run
on a single PC. VT technology will play a very important role in various types of processors (including
dual-core processors). This technology enables the processor to have and/or virtualization technology.
With Virtualization Technology, we can run two operating systems simultaneously on the same machine.
Power Technology
This item sets the way of Power management.
