Is Win7 64-bit system 4G memory enough?

Q: Is Win7 64-bit system 4G memory enough? My computer uses 4GB of memory, 32-bit system cannot support 4GB of memory, and if I want to replace it with a 64-bit system, will the 64-bit system take up more? RAM.

64-bit system does not take up more memory, just to support larger memory, generally installed Windows 7 64-bit Ultimate system installed all the required drivers, and did not install anything Too many other optional software will not take up more than 1.5GB of memory. Of course, with the extension of the system's use time, as well as the usage habits of different users, the operation mode, the ability to maintain 4GB of memory, etc., is no longer a problem with the system version.

The benefits of 64-bit systems can be used for a wider range of integer operations; larger memory can be supported. But because of the digital changes, it is simply assumed that the performance of a 64-bit processor must be better than that of a 32-bit system. In fact, 32-bit applications will perform even better on 32-bit systems and 32-bit processors. Even 64-bit processors are currently more powerful in 32-bit applications.

In general, if 4G memory is sufficient in a 32-bit system, 64-bit is enough. Even if 4GB of RAM is not enough, you can continue to upgrade the memory. 8GB of memory is definitely enough (64-bit system supports up to 128G of memory), and the memory is cheap.
