Among the CPUs currently produced by Intel, Pentium 4 and celon are PC oriented, while Xeon, XeonMP, and Itanium are for workstations and servers. Among them, Itanium is a 64-bit CPU that is completely different from other CPUs. It is not designed for use in existing Windows applications. Although other processors differ in the highest operating frequency, FSB (Front-End bus frequency), and cache capacity, the internal design is basically the same, wh
IPC (Instruction per clock):Number of commands executed by the CPU per clock cycle
In fact, the frequency and IPC really affect the CPU performance. Accurate CPU performance judgment criteria should be:CPU performance = IPC (number of commands executed by the CPU per clock cycle) x frequency (MHz clock speed)This form

Today, a problem arises: what is a 32-bit CPU, a 32-bit OS, and a 32-bit program? Why can 32-bit CPU only support 4 GB memory?
This problem occurs. Today, I ran SSIS and found that the memory was not enough. I checked the memory and found that 4 GB memory only showed more than 3 GB memory. I want to add memory. But I have heard that 32-bit computers can only support 4 GB memory at most. Why? I don't know.

Computer used for a long time, the computer will be a lot of ash, especially the CPU fan, resulting in poor heat dissipation, slow running and so on a series of problems. Today's small knitting to teach you how to remove the CPU fan.

the recording time was over 30 seconds, I found that the memory and cpu parameters were still quite normal. When I looked at the disk, it was so bad that it actually occupied 100% of the total, the saved temporary file also has more than 1 GB. After seeing such data, I was again silenced.
Although the attempt ended in failure again, it has improved a lot compared with the previous one. At least three minutes of recording can be used to record instant

In Windows, the operation system does the allocation for you based on CPU usage. you can set the affinity but, it will not determine which processor you run on. on the Xbox 360, the affinity is needed otherwise the 360 will not allocate your threadA s

Have seen a few times before the concept, but still always remember, simply write it down, easy to see in the future ~The so-called clock time is also called the wall clock time, it is the total number of clocks that the process is running, and its value is related to how many processes are running concurrently in the system, although it is generally measured when there are no other activities in the system when discussing clock time.User CPU Time: Is
radiator. Due to improper installation caused the radiator and CPU contact bad, the impact of the CPU heat dissipation, after a long period of use, greatly shorten the life of the CPU.
Summary: For general computer failures, if the system is not completely paralyzed, we rarely suspect the possibility of CPU damage. B
What is a computer CPU? Cup is the CPU (central processing unit), which is the computing core and control core of a computer.
