As computer configurations become higher and higher, especially when we run more and more software and require larger memory, the maximum memory usage is 4 GB in 32-bit systems, however, in actual use, there may be more than 3G. For example, our programmers may open multiple Visual Studio 2010 and open some other software, and the computer will be stuck there. Previously, my computer used the win7 32-bit system, 2 GB of memory, and the memory usage was usually above 80%. At that time, the computer was very stuck. In my opinion, when memory usage is high, there will inevitably be a lot of memory fragments, and the use and management of memory becomes a burden. A few days ago, I added 4G memory and switched to the 64-bit win7 system. Then I observed that the memory usage is only around 30%. When the memory usage is more than 2 GB, the computer is still running very smoothly. It can be imagined that there is no need to consider memory usage or insufficient use, and there are 3 or 4 GB of memory available, even if it is used. Many may want to install a 64-bit system. Check whether your machine supports 64-bit. Most dual-core machines support this function. You can also view it in the following way. There are also specialized software for viewing on the Internet.
1. Click Start, right-click computer, and select Properties.
2. Select to refresh the Windows experience Index
3. Click to view and print detailed performance and system information.
4. Check whether 64-bit is supported in the system column. (If your system is of the 64-bit version, it is not displayed here, because obviously, it must support 64-bit)
To check whether Windows XP runs 64-bit windows, you need to download the Windows 7 update consultant. If the 64-bit system is not supported, there will be a Red Cross, for example, the 64-bit system is supported but not installed:
