Parameter Intel Hyper Threading Technology Description 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. Setting the active processor core. Option Enabled Disabled Active Processor Cores All 1 2 3 Enabled Disabled Execute Disable Bit Capability When this item enabled, the processor prevents the execution of code in data-only memory pages. This provides some protection against buffer overflow attacks. Intel Virtualization Technology Select whether to enable the Intel Virtualization Enabled Technology function. VT allows a single platform to run Disabled multiple operating systems in independent partitions. Intel Advanced Encryption Standard Instructions Enabled (AES-NI), is a symmetric block cipher that Disabled encrypts/decrypts data through several rounds. AES-NI can be used to accelerate the performance of an implementation of AES by 3 to 10x over a completely software implementation. Conventional Intel SpeedStep Technology switches both Enabled voltage and frequency in tandem between high and low Disabled levels in response to processor load. In HW_ALL mode, the processor hardware is responsible for coordinating the P-state among logical processors dependencies. The OS is responsible for keeping the P-state request up to date on all logical processors. In SW_ALL mode, the OS Power Manager is responsible for coordinating the P-state among logical processors with dependencies and must initiate the transition on all of those Logical Processors. In SW_ANY mode, the OS Power Manager is responsible for coordinating the P-state among logical processors with dependencies and may initiate the transition on any of those Logical Processors. HW_ALL SW_ALL SW_ANY Intel AES-NI Support (Intel Advanced Encryption Standard Instructions) Intel EIST Support (Enhanced Intel SpeedStep Technology) P-State Coordination Intel Turbo Boost Technology When this feature is enabled, the processor can Enable dynamically overclock one or two of its four processing Disable cores to improve performance with applications that are not multi-threaded or optimized for quad-core processors. Select whether to enable the C1 Enhanced mode for the Enabled processor. If enabled, all logical processors in a physical Disabled processor will run in a C1 state. Enable/Disable C3 Report. Enabled Disabled C1E Support CPU C3 Report 39
