Processor Configuration Parameter Intel Hyper Threading Technology Active Processor Cores Description Option 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. Enabled Disabled Setting the active processor core. All 1 2 3 Execute Disable Bit Capability Intel Virtualization Technology When this item enabled, the processor prevents the execution of code in data-only memory pages. This provides some protection against buffer overflow attacks. Enabled Disabled 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 AES-NI Support (Intel Advanced Encryption Standard Instructions) Intel EIST Support (Enhanced Intel SpeedStep Technology) Intel Turbo Boost Technology 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. When this feature is enabled, the processor can Enabled dynamically overclock one or two of its four processing Disabled cores to improve performance with applications that are not multi-threaded or optimized for quad-core processors. 40
