How much memory can the XP system support?

There are a lot of friends on the computer memory there is a misunderstanding, that is to think that as long as the computer installed a large amount of memory, the system will read how much memory, in fact, whether it is XP, WIN7 read memory will have a limit, when we installed more memory than the limited memory, the extra part is completely ineffective.

How much memory does the XP system support? XP system is divided into 32-bit system and 64-bit system, read the quota of memory is not the same, like the XP32 system can only read 3.25G of memory, if you install 4G memory, then the extra memory is completely useless. If you have a XP64 bit system, you can read 128G physical memory and 16TB virtual memory.

Therefore, if your computer memory to install a relatively large, then recommend that you install 64-bit operating system, can be fully used.
