CPU Information Socket 0 CPU Information CPU Type/ Signature / Microcode Patch / Max CPU Speed / Min CPU Speed / Processor Cores / Intel HT Technology / Intel VT-x Technology Displays the technical specifications for the installed processor. Intel HT Technology / Intel VT-x Technology Displays the support information for the installed processor. Cache Information L1 Data Cache / L1 Code Cache / L2 Cache / L3 Cache Displays the technical specifications for the installed processor. CPU Speed / 64-bit 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. Active Processor Cores (Note) Allows you to determine whether to enable all CPU cores. Options available: All/1/2/3. Default setting is All. 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 processor more vulnerable to buffer overflow attacks. Options available: Enabled/Disabled. Default setting is Enabled. Hardware Prefetcher Select whether to enable the speculative prefetch unit of the processor. Options available: Enabled/Disabled. Default setting is Enabled. Adjacent Cache Line Prefetch When enabled, cache lines are fetched in pairs. When disabled, only the required cache line is fetched. Options available: Enabled/Disabled. Default setting is Enabled. (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. - 45 - BIOS Setup

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

.
Active Processor Cores
(Note)
Allows you to determine whether to enable all CPU cores.
Options available: All/1/2/3. Default setting is
All
.
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

Hardware Prefetcher
Select whether to enable the speculative prefetch unit of the processor.
Options available: Enabled/Disabled. Default setting is
Enabled
