1, the material used for the narrow plate saves a lot, which is directly reflected in the height of the memory. The height of the narrow board is only about half the height of the wide board (the size of the pcb board is about half smaller). 2. The overclocking performance and the maximum performance limit are very different. -Because materials are saved a lot, there is a big difference in various electrical properties. Now many computers can "automatically overclock" and "overclock with one button", which means overclocking will become a trend in the future. The overclocking performance of the narrow version is much worse. 3. Heat dissipation becomes worse. -Heat dissipation is also one of the most common problems in computers. The heat dissipation is poor, so computers are prone to more problems.
