According to the serial number of the hardware, the corresponding official website found the detailed information of the product, but now Samsung's hardware product has not been found.
Check CPU
Intel's CPU has been boxed for 3 years, so you can check the code through Intel's toll-free phone to distinguish the true from the false. As for the authenticity of AMD's batch CPU, there have been many articles on this site in detail, so I won't say much here. When you get the CPU, you should observe whether there is any damage around the CPU and whether the pins are twisted.
Check the motherboard
The main version should be packaged and the supporting accessories should be complete. As far as the whole motherboard is concerned, the first thing to look at is that the motherboard model given by the merchant is inconsistent with the motherboard model you want to buy; Second, see if there is a warranty label posted by the merchant; Third, look at the whole board for signs of damage; Fourth, see if there is dust in PCI slot, AGP slot and memory stick to prevent them from becoming the bottom of the merchant's warehouse; Fifth, it depends on whether the interface of the motherboard has flower marks, the most obvious one is the socket of the mouse and keyboard to prevent someone from using this motherboard; Sixth, some motherboard manufacturers provide 800 free hotlines. You should call to confirm whether it is genuine. As long as you check the motherboard at 6 o'clock as mentioned above, there is basically no problem.
Check memory
In terms of memory, the quality of memory chips produced by HY's original factory is very good, but a large number of unqualified polished memories pretend to be the market, which ruined the prestige of HY's original memory. Samsung, Kingston, KINGMAX and other brands have less false memories. If you are afraid of buying fake goods, you can verify whether it is real goods through the verification method provided by the manufacturer.
Look at the parallel hard drive
There are no fake hard disks, only parallel and licensed products from regular agents. The warranty service of parallel hard disks is poor. According to the agent's understanding, Hitachi's hard disk has been packed in a hard disk box, and there is a warranty card for Hitachi's hard disk for consumers to use in the future. Seagate hard disk licensed products are marked with agent and nationwide warranty, and can also be identified through the 800 hotline provided by Seagate. Maituo has two kinds of goods on the market now. It is said that those with a one-year warranty are parallel imports and those with a two-year warranty are licensed, but hard disks with a two-year warranty will be much more expensive. Samsung and Western Digital don't have much contact with these two hard disk agents, so you can only go online to find information to understand clearly.
Check the graphics card
At present, the same core graphics card will be divided into many categories, such as standard version, advanced version, gold version, diamond version and so on. So many versions make consumers confused and don't know which one to choose. At present, the minimum memory of graphics card is 64M DDR, and the key is whether the bandwidth is 64bit or 128bit. The performance of the same capacity graphics card 128BIT bandwidth is more than 30% higher than that of the 64bit bandwidth graphics card, but the price difference is very small. The key is to find out whether the model is what you want, and don't change the gold version into the standard version casually. Specific identification methods, you can see the articles in the library of this site.
Optical drive inspection
Used for optical disk storage, such as CD-ROM drive, DVD, burner, etc. First of all, look at the complete package to see if there are any flower marks on both sides. If there are flower marks, it means that someone put the CD-ROM drive into the chassis, which proves that the CD-ROM drive has been used. You see, you have to have the warranty label of the merchant, which is basically no problem.
Chassis power supply
It is recommended to buy a brand when the chassis is powered on. The most important thing is that the chassis should be strong and the power supply should be stable. The most important thing to note is that the chassis is given a brand-name power supply, which requires connection to the front USB port. As for some fancy functions brought by some cases, the price will be very expensive. Personally, I think it is better for the average user to choose the price of these two things around 250, and the highest price should not exceed that of 300 yuan. The monitor should be certified by TCO99, and the quality of big brands such as LG, Samsung and Philips is guaranteed, so the warranty is more convenient.
After the computer is installed, check whether the driver inside is installed, and then run the classic test software 3DMARK200 1. If there is no problem, then the machine is basically fine.
