What is DDR memory?

DDR = Double Data Rate, DDR SDRAM = Double Rate Synchronous Dynamic Random Access Memory, commonly known as DDR by people. Among them, SDRAM is the abbreviation of Synchronous Dynamic Random Access Memory, which is synchronous dynamic random access memory. DDR SDRAM is the abbreviation of Double Data Rate SDRAM, which means double-rate synchronous dynamic random access memory. DDR memory is developed on the basis of SDRAM memory, and it still uses the SDRAM production system, so for memory manufacturers, only a little improvement on the equipment for manufacturing ordinary SDRAM can achieve DDR memory production, which can effectively reduce cost.

Use the search function to find the driver you need

Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.

If you have a laptop or an all-in-one PC, you can also use the product name to search, and then go to the download page which has all the drivers for this machine (including: graphics card, network card, sound card, etc.). For example, if your laptop product name is: "Dell A6-9220e Inspiron Flagship", then type "Dell A6-9220e" to find all the drivers for this laptop.

Search steps:

1. Enter a keyword in the input box and click the "Search" button
