Q: I've seen this term lately, and I don't know how to explain it. Why some CPU is doubled frequency lock, some did not answer: CPU main frequency = FSB number x times frequency FSB general to see motherboard support (usually two), also depends on the CPU itself (Intel out of 800 FSB P4). The frequency multiplier is al

packaging, specifications and even the graphics card label, the use of memory type, capacity, bit width, we can easily identify at a glance. Second, we can use hardware detection/testing software to see the video memory frequency, memory bit width, memory capacity and other details. For example, many people will use gpu-z to identify the video card memory information, in the lower part of the gpu-z will show the video card using the type of memory,

Ibus database high-frequency keyword Error Correction script-general Linux technology-Linux technology and application information, the following is a detailed description. After using ibus for a long time, I often suddenly find that some of the original preference or commonly used words suddenly fall behind, or even to the second page, it is not squeezed out by other words, however, the ibus user database may be out of order. I don't know whether th

By default, the Windows 7 system Synchronizes time automatically once a week. For those who have strict requirements on time, the frequency is too low. In this regard, the author provides two methods to adjust the time synchronization frequency of Windows7 system. Under www.2cto.com by default, Windows 7 automatically synchronizes time every week. For those who have strict requirements on time, the

Article Title: CPU frequency adjustment in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. There are third-party CPU frequency adjustment software developed by Windows. In fact, there have been related software in linux for a long time. The default CPU operation

I am so ashamed to learn "digital signal processing" for a long time. I also remembered the Fourier transformation formula and made the FFT program, but I don't know what the significance of Fourier transformation is! That's it !! Fortunately, I understand it. Aside from the mathematical meaning, let alone some practical meanings. Fourier transform is used to convert signals from the time domain to the frequency domain. In this way, the characteristic

Label: blog HTTP using Java file SP Div 2014 C 1. before doing this project, I had worked on some projects in the OO class, and I was very familiar with this algorithm. Therefore, I learned the simple lexical algorithm and file operations in the C # language, it is expected to be written in one day.2. In fact, I found that C # is a little different from Java I have learned before. The algorithm is very simple, but it took a lot of time to learn to use C #. It took two days to complete the proce

After a piece of work, I decided to play with the super-frequency. I took a layer-2 bf531 board and tried to overtake it. from 400 to 600 m, the chip was running stably, I hit it with an infrared, and kept the temperature below 36 degrees. Well, I think of the famous saying of our hardware buddy who used the Beidou system. The high level of layout is to deploy the Six-layer layout on two layers and ensure stability! ***********************************
