Kingston, Weigang and Yu Zhan are famous in China, but the memory quality of these three brands is average and expensive. Because these three brands do not have the ability to produce memory particles themselves, they all buy memory particles from memory particle manufacturers such as Magnum, Hynix, South Asia Yisheng, Samsung and Elpida, and then produce their own PCB boards. Buying particles will definitely make particle manufacturers profitable, and the money earned by particle manufacturers will of course be added to the memory price. The quality of Kingston memory at the same price is far less than that of magnum. In fact, there are many memory manufacturers who are unable to produce granules, but I just don't recommend buying these three brands because they are more famous and inevitably more expensive.
