电脑8g内存可用内存只有3.25g(win10电脑4g内存够用吗)

The highest memory recognized by Win732-bit system is 3.25G. Only 64-bit operating system can recognize memory above 4G, so you can consider it If you switch to 64-bit, 8G of memory can be recognized. As long as you have an independent graphics card, it will basically not occupy your memory. XP 64-bit system is also available, which is currently the most stable and software-compatible 64-bit system.

Whether the installed software 360 ​​acceleration ball supports 64-bit operating system? If not, download and install the 64-bit version of 360 tools.
Do you have two 4G memory sticks or one 8G memory stick?

Installed memory (RAM) 8.00GB means that the total physical memory capacity actually installed on the device is 8G, and 3.25G available means the memory capacity that can be used in real time, indicating that the system has used 4.75G of memory. A total of 8G is available with +.

The role of RAM is to provide fast reading speed for system operation. As the number of open applications and documents increases, the CPU will transfer more data into the memory, and the available memory space will gradually decrease. Used memory and available memory change dynamically.

Extended information

Memory adjustment method:

1. Close documents and applications that are not in use for the time being

< p>As the available memory decreases, the running speed of the system will decrease and it will obviously feel stuck. At this time, you need to close some documents and programs that are not used temporarily to release the occupied memory space and reserve a certain amount of available memory for the system to run. Very important.

2. Install physical memory

The most direct and effective method can fundamentally solve the problem. Dual-channel large-capacity physical memory can fully unleash the potential of the CPU.

3. Set virtual memory

Programs need to be executed through memory. If the executed program takes up a large amount of memory, it will cause the memory to be exhausted. To solve this problem, Windows uses virtual memory technology, which allocates part of the hard disk space for memory use. When the memory is exhausted, the computer will automatically call the hard disk to act as memory to relieve memory tension.
