Automatic overclocking occurs because the motherboard supports automatic overclocking under heavy load.

In the bios of the motherboard, there is a D.O.T? Control(D.O.T control) and D.O.T. (dynamic overclocking technology) self-dynamic overclocking has technical dynamic overclocking function, including MSITM. In the brand-new CoreCellTM technology, it is used to detect the load state of CPU when processing applications and automatically adjust the optimal frequency of CPU.

When the motherboard detects that the CPU is running a program, it will automatically speed up the CPU, making the program run more smoothly and quickly. When the CPU is temporarily suspended or the load is low, it will restore the default settings. In general, dynamic overclocking technology (DOT) will only play a role when a user's PC needs to run a large number of programs, such as 3D games or video processing. At this time, the increase of CPU frequency will improve the performance of the whole system.

Extended data:

In the Nehalem micro-architecture, each processing core has its own PLL synchronization logic unit, the clock frequency of each core is independent, and each processing core has its own independent core voltage. The advantage of this is that it can almost completely shut down a single processing core during deep sleep.

It is precisely because of the special design of Nehalem that it has a very important technology, which is also very practical for users, that is, Turbo Boost technology, which can make the kernel run faster dynamically. You can turn on, turn off and speed up the operation of single-core or multi-core as needed. For example, in a quad-core Nehalem processor, if a task is single-threaded, the other three cores can be turned off and the main frequency of the working core can be increased, so that the overall energy efficiency ratio of the system and CPU can be improved through dynamic adjustment.
