If the DRAM individual crystal capacitors cannot be refreshed, memory data may be lost or incorrect. The specific situation: 1. The performance of the memory module is low and the operation is unstable. 2. When running a program or other operations, there will be memory errors such as read-only, insufficient memory, and so on. 3. The system crashes and the computer has a blue screen and a black screen. So what will cause DRAM to fail to refresh?

1. The particle quality is too bad, the frequency is not going up, the refresh rate is slow, but the leakage is very serious. Such granules are generally black sheets. Therefore, you must pay attention to the choice of memory, even a wafer manufacturer LOGO is not, you must not.
2. DRAM requires a process of charging and discharging. If you want to speed, you can't reach it. Pressurized overclocking, although refreshing is fast, the speed of discharge is constant. This limits the speed of the refresh, which limits the frequency of the memory bank. The memory module frequency is too high, refreshing too fast, and easily leading to data loss and errors.
Many times we blame all the problems on the memory stick when the computer's memory is faulty. In fact, it is inaccurate and unfair.
