AMD platform has always provided strong overclocking performance and a variety of playability. Last month, amd just released the LEO platform, now let's take a look at the LEO platform with the latest 890 series chipset and ddr3 memory. What kind of surprises can it bring to us during overclocking. Now use ASUSThe m4a89gtd Pro/usb3 motherboard is used as an example to describe overclocking BIOS settings in detail.First, let's introduce my basic configurations:CPU: AMDPhenom II X4 955 (Rev C3, ba
Assembled computer friends generally must have a certain understanding of computer hardware, must understand its balance, the balance between components and hardware performance, processor is computer enthusiasts are very concerned about, so what kind of processor is a good processor (CPU)? Generally we look at the main processor parameters can be known in the current processor to what level, today to explain the processor
General CPU failures are the following: thermal failure, restart failure, black screen fault and overclocking failure

Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate.

The full name of CPU is central processing unit, that is, the central processor.

The CPU occupies a high amount of unnecessary. Application response is slow. Suffers from the lack of analytical tools.
Oprofile leverages CPU hardware level performance counters (performance counter) to help us identify CPU-hogging "culprit" from process, function, and code levels by
Walk the computer market and you'll be pleasantly surprised to find that computers configured with more than 1Ghz of CPUs have become the mainstream of the market. When the CPU is more than 1GHz, the maintenance of the hardware CPU becomes the first important event, if still not enough attention, will cause computer failure or even crash, burn. CPU is like a huma
When we use the Windows XP operating system, we are slow to use it, and we see "Task Manager" to find that CPU occupancy is up to 100%. What the hell is going on? There is a virus, hardware problems, or system settings have problems, in this article I will be from the hardware, software and virus three aspects to explain the system resource occupancy rate of why it will reach 100%.

It represents the average workload of the system at 1, 5, 15 minutes. So what's the load? How does it relate to CPU utilization?Load average: The system average load is the load of the CPU, which contains information that is not

The basis of a multi-channel program operating system. By switching CPUs between processes, the operating system can increase the throughput rate of the computer.For single-processor systems, only one process is allowed to run at a time: any other process must wait until the CPU is idle to be dispatched.
The CPU selects a process from the ready queue according to a certain scheduling algorithm, gi

Linux provides a wealth of commands to monitor CPU-related data, such as top and vmstat. Top is a dynamic display process, that is, you can press the key to continuously refresh the current status. If you execute this command on the foreground, it will exclusively occupy the foreground until the user terminates the program. More accurately, the top command provides real-time monitoring of
When we use the Windows XP operating system, the system slows down when we use it. When we look at "Task Manager", we find that the CPU usage reaches 100%. How did this happen? In this article, I will explain why the system resource usage reaches 100% from three aspects: hardware, software, and virus.
CPU usage is usually 100%, and the main problems may occur in the following aspects:
