Q: I heard that CPU two cache on the CPU overclocking has a certain impact, what is the impact?A: Yes, CPU integrated two level cache, can effectively improve the performance of the CPU, but for overclocking, it is a bottleneck problem. The old Pⅱ, Pⅲ processor Two cache frequency is half the

the difference between CPU bulk and boxed From the technical point of view, the bulk and boxed CPU is not the essence of the difference, at least in terms of quality and performance does not exist problems, more impossible to have a fake CPU (no manufacturers can counterfeit such high-tech products), of course, do not rule out profiteers after grinding to low fr

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 CPU Fan How to remove (text) How to remove the CPU fan 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. Related

A question was discussed with a reader friend last night:on a multi-core CPU Web server, there is a load imbalance, in which the load of CPU0 is significantly higher than other cpux, further investigation indicates that the PHP-FPM suspicion is very large. I have previously documented a similar problem with soft interrupts, but in this case we can exclude suspects.Let's sample the data on a four-core server to see if there is a load imbalance problem:

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
