f CPU Features
Press Enter to enter the sub-menu.
fHyper-Threading [Enabled]
Intel Hyper-Threading technology treats the multi cores inside the processor as
multi logical processors that can execute instructions simultaneously. In this way,
the system performance is highly improved. This item appears when the installed
CPU supports this technology.
[Enable]
[Disabled]
fActive Processor Cores Control [All]
Allows you to select the number of active CPU cores.
fLimit CPUID Maximum [Disabled]
Enables or disables the extended CPUID value.
[Enabled]
[Disabled]
fIntel Virtualization Tech [Enabled]
Enables or disables Intel Virtualization technology.
[Enabled]
[Disabled]
fIntel VT-D Tech [Disabled]
Enables or disables Intel VT-D (Intel Virtualization for Directed I/O) technology.
fHardware Prefetcher [Enabled]
Enables or disables the hardware prefetcher (MLC Streamer prefetcher).
[Enabled]
[Disabled]
fAdjacent Cache Line Prefetch [Enabled]
Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher).
[Enabled]
[Disabled]
fCPU AES Instructions [Enabled]
Enables or disables the CPU AES (Advanced Encryption Standard-New
Instructions) support. This item appears when a CPU supports this function.

BIOS Setup
Enables Intel Hyper-Threading technology.
Disables this item if the system does not support HT function.
BIOS limits the maximum CPUID input value to circumvent boot
problems with older operating system that do not support the
processor with extended CPUID value.
Use the actual maximum CPUID input value.
Enables Intel Virtualization technology and allows a platform to run
multiple operating systems in independent partitions. The system
can function as multiple systems virtually.
Disables this function.
Allows the hardware prefetcher to automatically pre-fetch data
and instructions into L2 cache from memory for tuning the CPU
performance.
Disables the hardware prefetcher.
Enables adjacent cache line prefetching for reducing the cache
latency time and tuning the performance to the specific application.
Enables the requested cache line only.
