Why is my XP showing 3G than RAM

System problems, the XP system is 32-bit, and it can't display 4G memory.

If you want to display it, you need to use a 64-bit system, and some people use a higher version of the system, which is optimized, and may display a higher version.

It also has something to do with the motherboard.

XP 32-bit does not support 4G memory, so it is displayed like this, if you want to use 4G memory, please use a 64-bit operating system.

Programs in 64-bit systems are more memory-intensive, and the performance is not necessarily as good as that of 3G memory).

If you are sure that both are 2G

Then rule out the problem of poor compatibility of the memory support of the motherboard of the old machine.

It has to do with your other devices, such as the system BIOS, motherboards, graphics cards, expansion cards, storage bodies, and other PCI devices, all of which have their own storage space, and they all take up a portion of the system memory, so that there is less memory left to recognize.

But I feel like you're a lot smaller, and you'll see if there's any other problem, like which settings aren't very good......

XP operating system does not support 4G memory because you and your friends have different XP versions caused by different display want to use 4G memory It is recommended that you upgrade to the visit operating system There will be no abnormal display problem.

This has something to do with the processing speed of the CPU, because the CPU can't reach the ideal 32-bit state.

===Don't do the first reply, only the best reply ==

There are three ways to fix this:

1.Install the 64-bit win7 operating system, basically the mainstream software now supports the 64-bit operating system. Moreover, 64-bit systems are also compatible with 32-bit software, so the software compatibility problem you are worried about is basically non-existent.

2.Use Readyfor 4GB, this software.

It works by cracking the Windows PAE kernel file, bypassing the licensing restrictions of the ZWQueryLicenseValue API function, and enabling 32-bit x86 Vista Windows 7 to support more than 4GB of physical memory.

Now there is a discussion on the Internet about whether Hu Suiye's readyfor 4GB is real science or pseudo-technology. But whether it's really useful, I think it's better for you to try it yourself, and it's better to try it yourself than to hear hearsay.

3.If you just want to use the remaining memory, you can use the RAMdisk software to make the remaining unrecognizable memory into a temporary system disk, because it is a direct memory read, so the speed is much faster than what you set on the hard disk.

You can choose to install a 64-bit system! But you can't install the limb hall directly under the 32-bit system, and the recommended software NT6 HDD installer is very convenient!

Only 3G can be recognized, and 64-bit systems can recognize 4G

XP is also available in 32-bit and 64-bit configurations. The 64-bit one can recognize more than 4GB of memory, but the compatibility is not very good, and few people use it. Generally speaking, XP is 32-bit.

The addressing capability of the bit operating system is 4G, but some should be reserved for hardware use, so the available memory left for the user is generally . The rest is wasted.

2. If you have more than 4GB of physical memory, you must use a 64-bit operating system. With a 32-bit system, a lot of memory is wasted. At most, use the RAMdisk class software to virtualize as a virtual disk, and then put the virtual memory.

But this is useless, because the virtual memory Microsoft recommended value is multiple of the physical memory, and doing virtual memory, the system is prone to crash because it is small.

3. It is still the total memory, but the application, the 32-bit one can only use 2GB. You need to add 3GB of RAM to use 3GB of RAM, which is very restrictive. Therefore, even if it is within the memory, it is not used well. It's better to switch to a 64-bit system.

XP, 32-bit can only use memory, can only use so much, it is impossible to use 4GB

This problem is normal, it is not the system itself, but the number of bits in the system, we know that whether it is XP, win7 or win8 have 32-bit and 64-bit systems, resulting in the above situation shows that we must be using 32-bit operating system, and because the 32-bit system is still more mainstream for everyone, the above problems are more common. The 32-bit system theoretically supports up to 4G memory, and some of the memory it disappears is a memory hole, which is occupied by hardware devices such as hard disks, optical drives, sound cards, graphics cards, and wireless network cards. Due to the different hardware configuration of the machine, the size of the allocated memory space is also different, and the memory capacity has, 3GB, and other different sizes and capacities, which is why we see a variety of small capacities.

The best way to solve this problem is to install the increasingly mainstream 64-bit operating system, which can solve the hole of insufficient free capacity of 32-bit memory. In addition, the 32-bit system can also use some cracking tools, so that the Win7 system can also display 4GB memory available, which will not cause system instability, so it is generally not recommended.

Normal, 32-bit XP can only recognize so much! My 4G RAM shows up as!

Hello landlord! Windows XP only supports the maximum memory, some can only support the memory, and some also depend on the limitations of the motherboard, such as Sony Vaio's Ben 4 early model, the computer also indicates that it only supports a maximum of 768M memory. If your new machine is equipped with 2 2G memory, but the installation is Windows XP operating system, then it is a bit sad that the memory is read out, and only recognized, and some memory is wasted.

Using Windows 7 can effectively break through the limitation of 4G memory:

There are 7 major versions of the Windows 7 family:

1. The OEM installed version is the starter version, 32-bit operating system, and the maximum support is 2G

2. Home Basic 32-bit maximum memory supports 8G

3. Home Premium 64-bit Max memory supports 16G

4. Windows 7 Professional (Professional) 64-bit maximum memory support 192G

5. Windows 7 Enterprise Edition (Enterprise) 64-bit maximum memory support 192G

6. Windows 7 Home Server Edition, 64-bit maximum memory support 192G

7. Windows 7 Ultimate Edition (Ultimate), 32-bit maximum memory support 16G

Note: Microsoft has officially announced that it will end support for Windows XP on April 8, 2014, when Windows XP will no longer have new automatic update patches.

I hope the above suggestions will be a reference for the landlord.
