Each memory through the various types of manual testing, make the product can used in different application environments,be able to provide users with both high-percompatible withmance and high stability of the computer experience.Whether it is general user, gamers, or computer enthusiasts, can feel TAISU memory bring the percompatible withmance improvement compatible with computerHard disk/flash memory vendors are using decimal arithmetic: 1MB=1000KB, 1G=1000MB calculated, but the operating system is using binary arithmetic: 1MB=1024KB, 1GB=1024MB. So there are some differences between display capacity and nominal capacity of hard disk/flash memory products. However, this is allowed to exist.
