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 dynamically accelerate the core operation. 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.
Lynnfield core's Core i5-750 (Core i5-750) and Core i7-860/870 (Core i7-860/870) can support Turbo Boost technology, which is more powerful than Bloomfield core. For example, the highest single-core turbo frequencies of Core i5-750 and Core i7-920 with the same frequency are 3.2GHz and 2.93GHz respectively.
The core frequency of Core i5-750 was also verified in the test. When the BIOS is set to Auto, the frequency doubling of Core i5-750 will be automatically increased from 20x to 24x by specifying the SuperPI of the first core running single thread. At this time, the first core frequency reaches 3.2GHz, and the core voltage is also increased from 1. 15V to stabilize this frequency.
Before upgrading to Turbo frequency, PCU power consumption control unit shall conduct testing to ensure that TDP will not exceed the rated range. That is to say, turbocharging technology is quite safe and reliable. It gives full play to the power of CPU, and all this is automatic. For many ordinary users, you can get tangible benefits.
Intel i5 i7 Turbo Boost Technology
Intel turbo boost technology is a unique feature of Intel Core i7 processors and Intel Core i5 processors. This technology can intelligently accelerate the processor to provide the best performance for high-load tasks-that is, maximize performance to match the workload.
Acceleration technology definition
Intel turbo boost technology means that when there is enough space to increase the main frequency, intel turbo boost technology supports one or more processing cores to run at a frequency higher than the rated frequency. Therefore, it can support the processor to automatically and flexibly improve the performance of the processor according to the strength of the application program, and the processor can automatically and intelligently complete the work of improving the running frequency without user intervention.
principle of operation
When the operating system encounters computation-intensive tasks (such as processing complex game physics engines or previewing multimedia editing content in real time), it needs CPU to provide stronger performance. At this point, the CPU will judge whether its current working power, current and temperature have reached the highest limit. If there is extra space, the CPU will gradually increase the frequency of active cores to further improve the processing speed of the current task.
superiority
The easiest way to prove the advantages of intel turbo boost technology is to compare it with the heaters in cars. In normal mode, the heater will provide some heat through the dashboard and floor vents. After closing the floor vent, it can provide more heat through the dashboard with extra power.
Intel Core i7/i5 processors are configured in the same way, providing the overall rated power for each core. However, if one or more cores are not using their rated power, the processor can automatically and intelligently transfer the unused power to the working core. In this way, the working kernel can run at a main rate higher than the rated frequency, thus completing the task faster.

Overclocking motherboard Microstar "Easy Overclocking" The second generation of "Easy Overclocking" technology-"Easy Overclocking Switch"
Many users are not very worried about inserting jumpers, so MSI engineers changed the original jumper design into a three-switch combination design. In fact, its principle is the same as the previous jumper design, except that the user only needs to wave three switches up and down to realize the corresponding overclocking combination, which further facilitates the user to overclock the processor.
MSI has used this simple and practical "easy overclocking" technology on a large number of P43/P45! Even on AMD platform, this technology is widely used. It provides a double switch design, which can adjust the frequency of HT bus from 200MHz to 220MHz, 230MHz and 240 MHz. Users can also achieve the purpose of improving performance through such a simple switch after purchasing low-frequency AMD processors.
The third generation of "easy overclocking" technology-"easy overclocking knob"
If some players think that the easy overclocking switch is not simple enough, MSI's third-generation "easy overclocking" technology-"easy overclocking knob" can be said to be extremely convenient.
As shown in the above figure, players can see the increase and decrease of external frequency in BIOS or operating system in real time by gently turning the "Easy Overclocking knob", thus completely getting rid of the situation that they have to restart the computer, enter BIOS settings first, and then adjust it before booting. Real-time overclocking can be realized by using MSI's "Easy overclocking knob" without tedious repeated startup, which is simple and easy to use.
At present, MSI's latest 790GX-GD70 motherboard adopts the technology of "easy overclocking knob", which provides a more convenient overclocking method for players. I believe that "Easy Overclocking Knob" will be widely used in other motherboards of MSI.
Asustek's "one-click overclocking" ASUS's "one-click overclocking" technology is far from being as simple as literally understood, and users need to make certain settings to achieve real one-click overclocking. Of course, this process is not complicated, we only need to set it once, and we can complete one-button overclocking without setting it many times in the future. The whole technology includes "turbine V" and "turbine key". First, we need to use Turbo V software (provided by the file attached to the motherboard) to set the state of the system, complete overclocking by setting CPU external frequency, voltage, frequency division and other options, and save the current overclocking state after success.
One-key overclocking is completed and saved by Turbo V. After that, we use the Turbo key to call up the just saved overclocking state, and click OK to complete the whole one-button overclocking setting part. Finally, after clicking the power button, we can make the system run in the previously set overclocking state. Know that the whole process is not as complicated as expected?
