How do I know if processor and motherboard are second hand? How to identify used processors and motherboards
How to check if processor and motherboard are used? For users who like to build their own computers, it is very important to determine if hardware is used, so today I will share with you how to determine if processor or motherboard is used.CPU
The CPU is divided into individual chips and a box, and box package has National Bank and parallel imports. There is an agent logo sticker on National Bank box, such as JD.com, Shenzhou Digital, etc., and there is a serial number, which can be requested.
Original Intel processor box will have original heatsink, except for K suffix processor, there are others, plus instructions, warranty cards, and stickers.
The CPU model, S-Spec number, and batch number will be printed on original processor. It must match number on box. If these three numbers are not marked, it is usually an ES or QS product that is used for testing. Generally, only certain treasures and certain fish can buy products, and price is cheap, but not everyone is recommended to buy.
There will be no dents on new CPU top cover, which is also key to checking if it is a used one.
New processors are very clean, there are no traces of silicone grease on top cover, and color of contacts is almost silvery white, while used ones are usually yellowish.motherboard
When you buy a motherboard, you usually buy first-line products, which is also best choice for Xiaobai. At very least, this avoids many problems, and a sufficient warranty is provided after sale. However, although product is genuine, some sellers may also send you some products returned by others. Although this does not affect use, if it is obsessive-compulsive disorder, it is a different matter. So how to judge whether motherboard is second-hand? Take ASUS motherboard as an example.
In addition to Chinese packaging, ASUS Bank of China motherboards also come with product information labels that include product name, agent, address, official website, and place of origin.
Most major brand motherboards have a sticker with product information, such as product serial number, detailed model, motherboard production date, etc. You can find this information on official website or public WeChat account.
For example, ASUS motherboards can be requested on official WeChat account, and since ASUS provides a one-year renewal service, when you sign up for a one-year renewal service, you can clearly understand whether national bank product you purchased is genuine.
The above is all about how to tell if it's genuine, so let's move on to how to look at used items.
A brand new ESD motherboard packaging bag won't have many wrinkles, and seals won't be damaged either.
Besides main board, everyone should carefully read instructions. The items mentioned in description must be in stock. This does not only apply to whether item is used. If there are other problems, seller can use this as a reason for not returning and exchange.
Check processor base pins carefully before installing. If pins are bent, it's a defective, used, or defective product.
Check screw holes of main board. If it's a brand new board, tin spots on screw holes are shiny and full, no scratches.
Check rear I/O interface, all interfaces should be clean and tidy, free of dust and oxidation.
