How much memory does a 32 bit system support, and how much memory does a 32 bit system support

In general, 32-bit systems only support the maximum memory (usually around 3G). If you want a 32-bit system to support more than 4G large memory, there is actually a way, just install a Primo Ramdisk virtual memory disk software!

With the help of this Primo Ramdisk virtual memory disk software, you can make the 32-bit system support more than 4G large memory, without cracking the system and not affecting the stability of the system. Since there is only 8G of RAM, it can only be said that a 32-bit system can perfectly support 8G of large RAM (test platform: 4570 +8G).

Why should you take the help of Primo Ramdisk?

Many netizens may have questions, why are there so many virtual memory disk software, why do you recommend primo ramdisk?

Reason 1, primo ramdisk has an official Chinese version; The second reason is that Primo RamDisk has a feature that other virtual memory disks do not have - the memory management interface (UIMMI is not recognized). The best thing about the Unrecognized Memory Management Interface (UIMMI) is that it allows 32-bit systems to support more than 4G of large memory!

The reason is simple enough, let's take a look at how to use Primo Ramdisk to support large memory on 32-bit systems! The first step is to *** Primo Ramdisk, which is known as the most powerful virtual memory disk software!

The 32-bit system can support 4GB, 32GB memory, 64GB memory.

1. The ordinary home version of the 32-bit operating system supports a maximum of 4GB memory, but it is actually impossible to fully use 4GB of memory. Generally around the to.

2. The 32-bit operating system of the enterprise version can support up to 32GB memory.

3. The 32-bit operating system of the data center version supports up to 64GB memory.

The relationship between the operating system and the CPU:The amount of memory recognition is directly related to the addressing of the computer's CPU. A 32-bit operating system can theoretically recognize 2 addresses to the 32nd power (4294967296B=4GB), but the computer also needs to connect peripherals (mouse, printer, keyboard, network card, sound card, graphics card, etc.) These peripherals also need to occupy address space.

The maximum supported memory is directly related to the operating system, even if it is a 64-bit processor, the memory supported by the 32-bit operating system is up to 2 to the 32nd power, which is 4G. In Windows 32-bit operating systems, the maximum recognition is only between and varies depending on the Windows version.

The addressing capability of a 64-bit operating system is 2 to the 64th power. That is17179869184G,Of course, this is only a theoretical value,It is impossible to use such a large memory in practice,At present, the 64-bit Windows system only supports a maximum of 128G。 At present, mainstream motherboards can only be added up to 16G.

The maximum amount of memory that can be supported by a bit operating system.

The bit operating system can support a maximum memory capacity of 128G.

To put it simply, x86 stands for a 32-bit operating system, and x64 stands for a 64-bit operating system. If the CPU is more than dual-core, then it supports 64-bit operating systems. If the computer memory is greater than 4G, then you generally need to use a 64-bit system, because 32-bit Windows7 or Vista only supports 3 25G memory at most.

And 64-bit Windows 7 will support up to 128G of memory.

There are two main benefits of 64-bit computing: it can perform a wider range of integer operations; Larger memory can be supported.

MemoryThis is the most significant advantage of a 64-bit system, which can use more than 4GB of memory. Most new desktops and laptops have at least 4GB of RAM. The problem is that 32-bit versions like Vista and Win7 are only capable of using about 3GB of RAM.

In contrast, 64-bit Windows can not only take advantage of up to 128GB of memory, but also be able to use memory mapping instead of the BIOS feature, allowing the operating system to truly use the full 4GB.

In general:

1. Under the Windows operating system, the 32-bit system does support up to 4G. The reason is that 2 to the 32nd power is 4G.

Second, but the 64-bit operating system is indeed not 128G. It is also 2 to the 64th power, which is about 17179869184G, so the 64-bit system, the memory module supports hundreds of millions of G, but the actual good motherboard may support up to 128G.

The maximum memory of 32 bits is 2 32 bytes = 4,294,967,296, which is 4G.

The theoretical maximum of 64 bits is 2 64 bytes = 18,446,744,073,709,551,616 = 18 EB, about 18 billion GB

32-bit refers to the 32nd power of 2, 8 * 1024 * 1024 * 4 = 4294967296 = 2 to the 32nd power, so the 32-bit system supports a maximum of 4G memory, and 64-bit is 2 to the 64th power = 18446744073709551616, divided by 8 * 1024 * 1024 = 2199023255552G, that is, 64 bits can support more than 2 trillion GB of memory!! It's too big, so it's going to have to look at the motherboard or something.

32-bit can recognize up to 128g, while 64-bit can recognize up to 128g.

The Akiba system is easy to use, and the game is very smooth!!

My win7 32-bit, with 4G of memory, but the system can only recognize it.

I just bought ACER,Installed with 32-bit win7 ultimate version,Can only be used。

It seems that it can only recognize my win7's system 2g*2=4g memory and only shows it because my graphics card shares 256m

The 32-bit system can only support up to 2G 64-bit system and can support up to 128 This is basic, but when it comes to cracking, of course, it's a different matter.

In actual use, a 32-bit operating system can use more than 4GB of memory;

For example, in Windows Server 2003, the maximum memory supported by each version is as follows:

The standard version supports RAM in the 32-bit version and up to 32 GB RAM in the 64-bit version.

The Enterprise Edition supports up to 32 GB of RAM in the 32-bit version and 1 TB RAM in the 64-bit version

The 32-bit version of the Data Center Edition supports 64 GB of RAM, and the 64-bit version supports 1 TB of RAM

The web version can support up to 2G RAM.

In the current computer knowledge, we know that the maximum memory supported by the 32-bit system of win7 system is about, that is, 2 to the 32nd power byte, which means that if the user inserts a 4GB memory module into a computer with a 32-bit Windows 7 operating system, then the system will only display the available memory capacity.

If your computer is installed with a 64-bit system of Windows 7, the maximum memory it can support is 2 to the power of 64 bytes, which is 16TB of memory.

The XP 32 can theoretically support up to 4G memory.

A 32-bit operating system can support a maximum of 2 to the 32nd power of bytes, which is 419430400 bytes, which is exactly equal to 4GB when converted to GB. This means that a 32-bit operating system can only read about 4GB of memory at most.

32-bit CPU design for 32-bit operating systems. The bits of the CPU refer to the amount of data that can be processed at one time, 1 byte = 8 bits, the 32-bit processor can process the amount of data that can process 4 bytes at a time, and so on.

A 32-bit CPU only has about 4G of memory addressing space, which is far from enough for some servers. If we need more memory addressing space, we need to upgrade the CPU. This is how the 64-bit CPU was born.

The 64-bit CPU extends the original CPU bus to 64, which makes the memory addressing range of the CPU reach 2 64. In fact, only newer 64-bit operating systems support larger than 4GB of RAM space, and large memory support can complicate the operating system's memory manager.

At a glance, they all answered the question.

The maximum memory supported by a 32-bit operating system refers to the number of bytes that can be addressed, and the number of bytes that can be addressed by a 32-bit operating system is the number of bytes that can be addressed by a 32-bit operating system. Therefore, 4GB here refers to the ability to address 4GB bytes, not the capacity size of 4GB. It's easy to confuse concepts here.

I don't know if you can understand it.

1024 bytes 1kb, 1024kb 1m, 1024m 1g, so 4294967296 bytes 4194304kb=4096m

4G, 32-bit system, there is reserved for the system, so the 32-bit system can only recognize and use memory at most.

My legion: help others, to this membership!

Theories are theories, after all.

It actually supports about 3G, and it has been reported.

If you crack it, the 32-bit system will also support more than 4G memory:

I don't understand what kind of bit you are talking aboutbyte?
