What is DDR2 memory?
DDR2 (Double Data Rate 2) SDRAM is a new generation of memory technology standards developed by JEDEC (Joint Committee of Electronic Equipment Engineering). The biggest difference from the previous generation of DDR memory technology standards is that although they both apply the basic method of data transmission at the same time on the rising / falling edge, the DDR2 memory has more than twice the pre-read capacity of the previous generation of DDR memory (that is, 4 bit data read pre-fetch). In other words, DDR2 memory can read / write data at 4 times the speed of the external bus per clock, and can run at 4 times the speed of the internal control bus.
As the DDR2 standard stipulates that all DDR2 memories are packaged in FBGA, which is different from the widely used TSOP/TSOP-II package, the FBGA package can provide better electrical performance and heat dissipation, as a solid foundation for the stable operation and the future development of frequency of DDR2 memory.
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
2. In the query results, find the driver file you need, and click the download button
