How much memory does the Vista system support?

                        How much memory does each Vista support? Now, everyone has always thought that Vista is a resourceless bottom hole, especially for memory capacity. However, the bigger the memory of the Vista computer is, the faster the machine is. So this article will tell you a positive answer: No!

Vista's memory requirements are like people's stomach, total There is a maximum that can withstand. For Vista, the maximum physical memory supported by each version has a fixed value.

In all versions of Vista, the Windows Vista Starter version is the one with the lowest memory capacity requirements, and its 32-bit version only supports up to 1GB of memory.

The 32-bit versions of Windows Vista Home Basic, Home Premium, Business, Enterprise, and Ultimate support a maximum of 4GB of content. Note that the so-called "4GB" is not the same as real physics. Memory, but refers to the available memory addressing space.

The maximum supported memory capacity of 64-bit Vista is much higher than that of 32-bit. On a system running x64 Vista Home Basic, you can add up to 8GB of memory, while x64 Vista Home Premium supports up to 16GB of memory.

But for x64 Vista Business, Enterprise and Ultimate, it can support up to 128GB of memory.

So, to put it this way, 128GB is the maximum amount of memory supported by Vista.

However, during the use of Vista, there is a significant gap between the maximum supported physical memory and the virtual memory that the operating system will use. When the physical memory installed in the system reaches the maximum value of 4GB, the x86 version of Vista does not fully support such a large amount of memory. It is believed that users with computer basics know that for 32-bit systems, 4GB is capable of addressing space. The limit, unless the memory above 4GB is mapped by the PAE (Physical Address Extension) as a page in 4GB space. In this 4GB address space, you must leave a location for the computer's system resources such as BIOS, graphics card, PCI-Express and other PCI interfaces. Again, there are such limitations on the x64 platform.
