fLimit CPUID Maximum [Disabled] Enables or disables the extended CPUID value. [Enabled] 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. [Disabled] Use the actual maximum CPUID input value. fExecute Disable Bit [Enabled] Intel's Execute Disable Bit functionality can prevent certain classes of malicious buffer overflow attacks where worms attempt to execute code to damage the system. It is recommended that keeps this item enabled always. [Enabled] Enables NO-Execution protection to prevent the malicious attacks and worms. [Disabled] Disables this function. fIntel Virtualization Tech [Enabled] Enables or disables Intel Virtualization technology.

[Enabled] Allows the hardware prefetcher to automatically pre-fetch data and instructions into L2 cache from memory for tuning the CPU performance. [Disabled] Disables the hardware prefetcher. fAdjacent Cache Line Prefetch [Enabled] Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher). [Enabled] Enables adjacent cache line prefetching for reducing the cache latency time and tuning the performance to the specific application. [Disabled] Enables the requested cache line only. 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. fIntel Adaptive Thermal Monitor [Enabled] Enables or disables the Intel adaptive thermal monitor function to protect the CPU from overheating.
