Please provide an XP version that can fully display 4G memory

Only 64 bits are OK, and 32 bits are only displayed left and right. The D version of the 64-bit XP is easy to buy.

It seems that the landlord is a big user of memory.

A 32-bit system cannot be used to 4G, so a 64-bit system is required.

The original 4GB memory capacity was.

Only the left and right are recognized. The reason why the motherboard and operating system can't use all 4GB of memory is the root cause of the computer's 32-bit x86 architecture.

The 32-bit x86 architecture means that the address bus of the personal computer is 32-bit, the CPU, the memory controller, and the operation.

The system is designed according to the 32-bit address bus. The memory address ** that the 32-bit address bus can support is 4096MB, that is, there are 4GB addresses**, and 4GB addresses can be programmed. These 4GB addresses.

The code can be allocated exactly 4GB of memory. However, these 4GB address codes cannot be allotted to the physical memory installed on the motherboard. Because PCs also have a lot of devices that need an address** so that the CPU can be able to follow it.

Address codes to find them, and the CPU and these devices exchange data with the memory – registers – that temporarily hold the data, and these registers also need addresses**. For example, hard disk controllers, floppy drive controllers, and management plug-ins.

The PCI slot on the PCI card is the PCI bus controller, PCI-E bus controller and PCI-E graphics card, all of which all have registers that need to be assigned to them by the system**. These addresses are assigned by the system, Electric.

Brain users don't feel it in use. As a result, when we plug in a total of 4GB of memory into our computer, some of the memory will not be allocated an address** and cannot be used.

The 32-bit operating system is designed according to the 32-bit address bus, and the 32-bit address register, so it can only manage 4GB of addresses, and it cannot be completely occupied by the system.

Uses the full 4GB of RAM. None of the PC's 32-bit operating systems can support 4GB of RAM, even Vista

Neither can 32sp1. vista

32sp1 than xp

32sp3 is a little more advanced in the system properties to show how much memory is actually installed.

Although the 4GB memory is not recognized under the XP system, it can be used around the right and left, so that it is fully suitable for personal needs (virtual memory can be disabled at this time).

If you feel that 4GB is not being used, you can set a part of the memory as a virtual hard disk, so that some software that needs to read and write the hard disk frequently is placed on the virtual hard disk, so that the entire memory is used.

The XP system only recognizes the memory below 4G, and cannot fully recognize 4GOnly 64 systems with Win7 installed can recognize systems above 4G.

The Windows XP operating system has been working continuously for 13 years, making it the longest-lived operating system to date. On April 8, 2014, Microsoft will officially end service support for Windows XP. You can continue to use it after the XP stops service.,Just like the mobile phone you bought.,The official website says that you don't update the flashing package!!

And XP stopped serving, but the official website does not update the vulnerability patch!

The biggest risk to continuing to be practical XP is security. Because if you don't update the vulnerability, it will give hackers a chance!! For the safety of the computer in the future, please upgrade the system of win7 or later.

Windows 7-64-bit: Win7-64-bit system requirements for computer configuration: need more than dual-core CPU (as long as it meets the requirements of dual-core) and at least 4GB or more memory.

This system is the best system in the current Windows system, the most mainstream system, the game compatibility is good, there are compatibility options in the "Properties" column, you can set the backward compatibility with a variety of low-level systems, and support the operation of virtual DOS programs, you can run games in the DOS era virtually, which greatly improves the compatibility of this system; It perfectly supports 4GB and above memory, and can support up to 128GB of memory; Support AHCI hard disk mode; Support DIRECT10 and up to the latest DIRECT11; Moreover, at present, most mainstream software and hardware manufacturers support the system, and mainly develop corresponding software for the system. Win7 has even been hailed as the next WinXP-style legend.

The XP system cannot support 4G memory, and can only recognize the left and right.
