Personal computer hardware information detection method

I. processor Information Detection

Although the remark CPU phenomenon has basically disappeared as the processor technology has been continuously upgraded over the past two years, due to the increasingly detailed differentiation of the current processor, even if the processor's series and clock speed are identical, they also support different functions. For example, in the previous articleArticleP4 530j and P4 531 +. Although the two processors are identical in most aspects, such as the front-end bus, interface type, and actual frequency, there is a fundamental difference in whether the 64-bit technology is supported, this will have a great impact on both the cost-effectiveness of hardware products and future applications.

CPU-Z

The most convenient way to detect processor information is to use CPU-Z. The latest version of CPU-Z has been updated to version 1.30, to accurately identify the current mainstream market of the full range of Intel and AMD processors (Click here to download ). On the "CPU" page of The CPU-Z, you can clearly see the processor model, core code, production process, cache capacity and supported instruction sets. If you are using a processor that supports 64-bit processors, then in the command set column will appear "X86-64", this need to pay attention.

Although the CPU-Z has the advantages of small and fast, but it can display the content is relatively limited after all. If you want to learn more about the processor, the best and most appropriate method is to use the official detection software. Here I will first introduce intel processor identification utility (Intel processor identification utility)Program), The program size is 878kb, you can click here to download. The intel processor identification utility supports a full range of Intel processors, including Pentium D, P4, sai Yang D, Pentium M, and even Xeon, the identification scope includes frequency testing, CPU technology, and cpu id data.

The frequency test page includes the processor model, FSB, L2 cache, expected frequency, and report frequency. Note that the frontend bus of different P4 boards may have a small gap, so as long as the gap between the reporting frequency (and actual frequency) and the expected frequency does not exceed 100 MHz, we can think it is normal.

The following CPU Technology page displays whether the Intel processor currently in use supports HT hyper-Threading Technology, Intel em64t technology, and enhanced speedstep technology. From these test results, we can clearly know whether the Intel processor we are using supports 64-bit processing, and avoid JS using 32-bit processor impersonating.

The cpu id data displays the processor model and other information. AMD's official CPU detection program is amd cpuinfo. The software interface is very simple and the information is clear at a glance. I will not give more introductions here. If you need this software, click here to download it.

Ii. Memory Information Detection

At present, counterfeit memory is rampant on the market and the simulation is very high. In addition to some conventional anti-counterfeiting methods, we can also use related software to further detect the authenticity of memory. Among them, CPU-Z and Everest are the two most commonly used memory detection software.

Memory Information Detection

Although CPU-Z is a software to detect processor information, but it can also read the information in the memory SPD, according to the information we can also judge the memory specifications and authenticity. We can learn about the module size (capacity) and Max bandwidth (maximum Specification) of the memory from the SPD page of The CPU-Z software to verify whether the dealer sells memory of the specified specification, if ddr400 exists in this project, the correct display should be "pc3200 (200 MHz)", while ddr333 is "pc2700 (166 MHz)", and so on.

Manufacturer, part number, serial number, and other information determine whether the memory is genuine. For example, the content displayed in manufacturer and part number in genuine Kingston is "Kingston" and "K". If the Kingston memory purchased by everyone cannot correctly display this information, it is very likely to be fake. Generally, the manufacturer information of Hy Assembly memory and counterfeit memory is "0000000000000000 ". The following lists the manufacturers and particle numbers of mainstream DDR memory brands:

In addition, you can check the memory SPD information on the motherboard> spd of the everst Home software. Everest software can be divided into multiple versions, including the Home edition, the Professional Edition, and the Enterprise Edition. The Home Edition is available for free, while the other two versions require paid registration. The free home edition is sufficient for most DIY players (Click here to download Everest Home Edition v2.20 ). Note that the evetst Home software combines the manufacturer and part number options in the CPU-Z into the module name item, as shown in ).

Evetst home Software

Finally, you can use the "Performance Test" function provided by Everest home to check the memory compatibility. The "Performance Test" includes three sub-projects: Memory read, memory write, and memory latent. Based on my experience, these projects can well detect the compatibility of your memory-if you pass the test, it indicates that the memory has good compatibility; if a crash occurs during the test, the compatibility between the memory and other hardware is abnormal. If you are interested, try again.

Iii. Overall system information detection

In fact, Everest is very powerful. It can detect the hardware information of almost all accessories including CPU, memory, motherboard, hard disk, video card, sound card, and BIOS version, in addition, Everest can detect the temperature of hardware such as processors and hard disks (which must be supported by the motherboard ). Here I will introduce the detection of CPU, hard disk and video card.

1. CPU Information Detection

CPU Information Detection

You can view the details of the processor on the motherboard> central processor> cpuid of Everest Home software. The "central processor" option mainly displays the processor model, clock speed, and other main information, while the cpuid shows in detail the instruction set supported by the processor and other features. Although compared with the official detection software released by Intel and AMD, the Everest home processor detection is not so authoritative, it displays more detailed information and can be used as a reference for the official detection software.

2. Hard Disk Detection

Hard Disk Detection

To learn more about the hard disk, go to Everest home and find the storage> Windows storage option. After you click it, you can see the configuration of the current computer storage device in the device description. For example, the author uses the Seagate st380013as hard drive (cool fish 7200.7 80 gb sata) on his computer ). After you click "st380013as", the software will display the speed, interface type, cache size, and other key information of the hard disk in detail, in this way, JavaScript cannot use a 2 mb ide hard disk to pretend to be an 8 Mb IDE hard disk or a SATA hard disk to cheat us.

3. Video Card Detection

Video Card Detection

From the Display Device of Everest Home> graphics processor options, we can see the hardware information of the video card. You need to pay attention to the chip type, core/Display memory frequency, memory capacity, bit width, and other important aspects of the video card, check whether the specification is consistent with that of the video card in the configuration sheet (display the hardware information of the radeon 8500 video card, we can see the video memory capacity, video memory type, default frequency, DirectX version and other detailed specifications supported by the video card ).
