The overclocking of the computer is to improve the working frequency of the CPU, graphics and other hardware by artificial way, so that they work stably under the rated frequency state. The Intel P4C 2.4GHz CPU For example, its rated operating frequency is 2.4GHz, if the operating frequency to 2.6GHz, the system can still run stably, then the overclocking was successful. The main purpose of

I. Preface in order to understand the meaning of this article more conveniently, it is better to look at the following cumbersome concepts and make it easier to understand. Do not understand these concepts, even after reading you can only know, run the next vmstat, look at the results of Linux feedback, but also to know why ~ First said the concept of memory. It's not about the CPU. Because the memory will consume

In the last blog post, we talked about how to get the results of executing the command line in Linux, and eventually get CPU usage, but unfortunately it is:1) via Top-n 1 | The CPU usage obtained by the GREP CPU is not refreshed, and the results of the first execution are only available for each read.2) may cause a conflict on signalThe new code solves the princi

Before the interview was asked, the cause of the CPU load is too high. How to quickly troubleshoot the cause.Open a post and summarize the relevant knowledge what is CPU load value The load average shown in the top command is the system average load for the last 1 minutes, 5 minutes, and 15 minutes. The system average load is defined as the average number of processes running in the queue during a specific

Choose 533 or 667? Detailed description of the relationship between CPU and memory I recently read some questions from some netizens about CPU, such as the gap between front-end bus 533 and 667, and how about the memory of ddrii667 on t2050 (Front-End bus 533 MHz ?...... I want to write thisArticleSo that more friends can understand this layer-by-layer relationship and know how to choose

A computer overclock increases the operating frequency of CPU, video card, and other hardware manually so that they can work stably at a higher rate than its rated frequency. Taking intel p4c 2.4ghz CPU as an example, its rated operating frequency is 2.4 GHz. If the operating frequency is increased to 2.6 GHz, the system can still run stably, and the overclocking is successful. The main purpose of

Loadaverage is displayed when we use the top command to view system resource usage, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the relationship between it and cpu utilization? When we use the top command to view the system resource usage, we will see the load average, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the rel

I tried to detect Keyboard Events in python by placing a function event. get () in pygame IN THE while loop. The result is that the cpu usage is always 100%. However, the event listening functions in the operating system and other languages (such as C #) basically do not occupy the cpu. How do they do this? Does it sacrifice the real-time response of events? I tried to detect Keyboard Events in python by pl

General CPU failure has the following: thermal failure, restart failure, black screen fault and overclocking failure (CPU go to die, of course, do not forget) 　One, the CPU pin contact is bad, cause the machine can not start General performance in a sudden unable to boot, the screen shows no signal output, excluding video card, monitor no problem, unplug the

IntroductionMpstat is the abbreviation of multiprocessor statistics and is a real-time system monitoring tool. Some statistical information about its report and CPU, which is stored in the/proc/stat file. In a multi-CPUs system, it not only can view the average status information of all CPUs, but also can view the information of specific CPU. Mpstat's biggest feature is the ability to view statistics for ea

Multi-Threading vs. CPU:1. Single-core CPU CPU-intensive program (the program to do the calculation) single-threaded (this time the task has already consumed CPU resources 100%, there is no need to use multithreading to improve computational efficiency)2. Single core CPU IO-

With the RX470 graphics card officially listed, these performance is second only to the RX480 and the relatively inexpensive graphics card has been favored by some players and attention. As a graphics product positioned slightly below 480, RX470 is very similar in design to RX480, with the main difference being the streamlining of some core specifications. So what's the problem, RX470 with what CPU and motherboard? If the next installed RX470 graphics

We are in the process of using the computer will inevitably encounter such or such a problem, where the computer blue screen is the problem we often encounter, when our computer CPU overclocking, it will easily damage the hardware, affecting the life of the CPU time. Blue screen is generally the reason for the hardware is incompatible, such as memory, driver incompatibility, and other system failure program

Recently in the upgrade netback, during the testing process, found that the VM full-duplex pressure, rx PPS Volatility is very strong, see the RX Kthread Although the CPU affinity is 0-7 (Dom0 8vcpu), but often run to the physical interrupt of the CPU.By manually binding the RX Kthread CPU to the other CPUs, Rx PPS is up and stable, and it is obvious that the PPS fluctuation of RX is due to

How do I install the CPU heatsink? The CPU heatsink is used to heat the CPU. Radiator on the stable operation of the CPU plays a decisive role in the assembly of computers to choose a good radiator is very important.

The concept of load average Load average in the top command shows the system average load for the last 1 minutes, 5 minutes, and 15 minutes. The system average load is defined as the average number of processes running in the queue during a specific time interval (running on the CPU or waiting to be run). If a process satisfies the following conditions, it is located in the run queue: it is not waiting for the I/O operation result it does not activel
